Sanctions, disinvestment and the anti-apartheid movement¶
Did trade, financial and investment sanctions, divestment and codes of conduct impose real costs and help end apartheid, and who bore those costs?
Works engaging the debate: 61
Positions¶
- Effective, especially the 1985 financial sanctions (Hanlon, Manby, Schwartzmann, Rodman)
- Trade sanctions trivial or counterproductive; financial withdrawal a market response to risk (Levy, Lowenberg, Lipton)
- Divestment imposed little cost on whites (Kaempfer, Teoh et al.)
- Sullivan Principles and constructive engagement: workplace reform vs withdrawal
Evidence base¶
Most of the debate rests on a thin layer of aggregate and secondary evidence. A few works do real data work. The most-cited quantities recur from paper to paper: the Hufbauer, Schott and Elliott estimate that trade sanctions cost about 0.5 per cent of GNP (roughly $354m a year); Jones and Müller's real GDP growth series showing a break in 1974; Waldmeir's figure of a 26 per cent rise in export volumes; and Industry Week's '$11 billion and 250 US firms' withdrawal figure. All of these reach the literature second-hand through (Levy (1999a)), (Miller (2004)) and Effect of Sanctions on South... (n.d.). The financial-sanctions case rests mainly on South African Reserve Bank (SARB) debt series. Hirsch (1989) uses the December 1987 Quarterly Bulletin to show short-term debt rising from 49 to 72 per cent of foreign debt between 1980 and 1985, with total foreign debt near 50 per cent of GDP. He adds OECD financial statistics, Euromoney league tables, CANNICOR estimates of creditor shares and leaked bank documents. Coulibaly (2005) combines SARB net capital inflow, foreign liability and current-account series with Trade and Industrial Policy Strategies (TIPS) investment, capital-stock and output-per-worker aggregates. It compares averages for 1976-84, 1985-93 and 1994-2001 and calibrates a borrowing-constrained growth model. The trade side has one econometric study. Evenett (2002a) (duplicated as Evenett (2002b) and Evenett (2002c)) runs year-by-year gravity regressions for 1978-1999 on World Bank Trade and Production/COMTRADE bilateral imports. The sample is 8 industrial importers and 31 middle-income exporters (248 pairs, trimmed to 199), with sanction effects identified by South Africa-importer dummies. Descriptive trade evidence comes from Overseas Development Institute (1986): 1984/85 commodity-by-destination data showing that the 1986 measures touched about 7 per cent of exports, or 16 per cent under a total ban on food, coal and steel. Becker (1988) adds the 1978 and 1985 input-output tables and Foreign Trade Statistics.
On divestment, the evidence is US stock-market data. Teoh et al. (1999) runs event studies using CRSP returns, IRRC (Bowers and Cooper) bank-loan and exposure data, and hand-collected Financial Times daily series for Anglo American, the JSE gold and industrial indices and the rand. It covers 10 legislative dates leading to the Comprehensive Anti-Apartheid Act (CAAA), 16 pension-fund divestments and 46 voluntary corporate exits. Wright and Ferris (1997) (31 announcements) and III et al. (1995b) (59 boycotts, 35 divestitures, 1969-91) use the same CRSP and press-dating approach. Wagner et al. (1984) builds a counterfactual portfolio from Wilshire's list of 229 South Africa-linked firms against the S&P 500 (152 constituents removed). Evidence on firm behaviour comes from IRRC withdrawal studies and Arthur D. Little Sullivan compliance reports, used in Rodman (1994) and Massie (1997). It also comes from UK Department of Trade and Industry (DTI) and Dutch and German government summaries of company reports under the EC Code, tabulated for 1977/8-1987/8 in Holland (1989). The same sources include Financial Mail top-100 rankings and a Commonwealth Secretariat count of 115 US withdrawals, 59 per cent sold to South African capital, in Nishiura (2006). Political-causation claims draw on elite interviews and private archives. Stemmet (2002) uses the PW Botha and Le Grange collections at the Institute for Contemporary History (INCH) and interviews with Botha, Malan and Coetsee. Massie (1997) uses the Diggs, ICEOP/Sullivan, American Committee on Africa and JFK Library collections plus more than 150 interviews. John (2000) uses Anti-Apartheid Movement (AAM) and End Loans to Southern Africa (ELTSA) reports and bank-chairman interviews. Rodman (1995a) relies on FOIA documents, GAO reports and bank interviews. Several of the most-cited contributions are theoretical: Lundahl (1984), (Becker (1987)) and Brealey and Kaplanis (1989). Others are advocacy or testimony with unsourced figures: Minter (1986), (Steward (2004a)) and Truth and Reconciliation Commission, Reparation and Rehab... (1998).
Contested evidence¶
The sharpest dispute is over the 1985 credit cutoff. Levy (1999a), (Lowenberg (1997)), (Steward (2004a)) and Holland (1989) read Chase Manhattan's July/August 1985 refusal to roll over loans as a market response to risk. Their evidence is a chronology in which private withdrawal precedes public sanctions, plus SARB-derived figures on short-term debt exposure. Hirsch (1989) reads the creditor composition the other way. US banks had shifted most heavily into short-term lending and acted first, which he takes as evidence that political pressure shaped creditor behaviour. Bowman (n.d.) notes that the June 1985 House vote preceded the Chase decision. Rodman (1994) and Rodman (1995a) treat congressional action as amplifying market and NGO pressure. Neither side has bank-level rollover data, so the same timeline supports both readings. A parallel conflict concerns timing and growth. Levy (1999a) uses Jones and Müller's period averages to place the break in 1974 and to show growth recovering after 1985-87. Bowman (n.d.), using Penn World Table 6.2, places the decisive relative decline after 1985, with South African GDP per capita falling from one third to one quarter of the US level. Coulibaly (2005) finds investment and output per worker below their pre-embargo trend paths during 1985-93. On trade, the Hufbauer 0.5 per cent of GNP figure and Waldmeir's export-volume rise sit uneasily beside (Evenett (2002a))'s finding that the CAAA cut South African exports to the US by about a third, with no recovery after 1991. Coulibaly (2005) and Teoh et al. (1999) report no fall in aggregate trade or in JSE and rand responses. Evenett (2002a)'s own EC result also flips with outlier trimming: from roughly a halving to about 27 per cent and mostly insignificant. The incidence of divestment is read from incompatible evidence. Teoh et al. (1999) finds no abnormal returns for exposed firms or South African markets. Wright and Ferris (1997) finds a significant -0.249 per cent day-zero return for divestors, so the costs fall on US shareholders. Brealey and Kaplanis (1989) and Becker (1987) argue theoretically that South African buyers gained a price discount. Rodman (1994) and Nishiura (2006) support the windfall reading with IRRC and Commonwealth evidence that exits mostly took the form of sales to local management or conglomerates that kept licensing ties. On who bore the costs, (Becker (1988)) infers from sectoral labour shares by race that whites lose more. Steward (2004a) asserts, citing unnamed surveys, that blacks were the main victims and opposed sanctions. Minter (1986) cites Sunday Times and Ilanga polls showing urban black support. On codes of conduct, the same company self-reports support different conclusions. Holland (1989) shows UK minimum-pay compliance reaching 97.6 per cent but attributes this to a lowered benchmark, set against an independent EIRIS survey. Gould (1981) and Massie (1997) read the Sullivan and Arthur D. Little reports as showing nominal progress. Wright and Ferris (1997) asserts, without employment data, that good-rated Sullivan firms were forces for reform.
Underused and missing sources¶
The source that would settle the most is primary SARB data at quarterly or monthly frequency. This includes the balance of payments, the capital account by type, foreign debt by maturity and creditor, the financial rand discount and the debt-standstill and rescheduling records. These could date capital flight against unrest, the Rubicon speech and congressional votes. Only (Hirsch (1989)), (Coulibaly (2005)) and, in passing, (Aron and Muellbauer (2006)) draw on the Quarterly Bulletin directly; Levy (1999a) never does. So is the ELTSA archive at the Bodleian, noted in Effect of Sanctions on South... (n.d.) and used only through movement publications by John (2000). For trade, product-level COMTRADE data separating sanctioned goods (coal, iron and steel, agriculture) from unsanctioned ones (gold) would test (Evenett (2002a))'s pair dummies. Shipping Research Bureau oil-embargo data, used only anecdotally by Minter (1986) and Van Vuuren (2006), could be used to cost circumvention. Cabinet and State Security Council minutes, which (Steward (2004a)), (Stemmet (2002)) and Levy (1999a) all invoke implicitly, remain unused apart from Stemmet's INCH private collections. Three further kinds of evidence are rarely used. One is firm-level IRRC withdrawal and post-sale licensing data. Another is UK DTI Code reports at company level rather than in national summaries. Together these would let incidence on white voters, black workers and buyers of divested assets be measured rather than asserted. No study attempts a formal counterfactual, such as a synthetic control against other commodity exporters.

Works and their positions¶
| Work | Position |
|---|---|
| Aron and Muellbauer (2006) | Treats sanctions and the debt crisis as constraints on capital and trade that weakened growth and real house prices and raised the relative price of durables, but does not test this causally. |
| Barber (1991) | Notes the British government's claim that engagement and contacts helped bring reform, but says it cannot be proved or disproved. Treats the sanctions dispute as a clash of convictions, not a testable question. |
| Barber (1991) | Sceptical. Argues the dividend can be exaggerated: investors need stability and profit prospects, and international capital markets are now less hospitable. |
| Becker (1987) | Argues against the claim that all effective sanctions would greatly hurt poor blacks; carefully designed sanctions (high-tech export ban, gold/diamond boycott) could spare unskilled nonwhites in the medium run, though an oil embargo would not. |
| Becker (1987) | Critical of forced divestment, which would give white South Africans windfall gains and could worsen conditions for black workers; prefers a ban on new investment. |
| Becker (1987) | Sees clear gains for skilled nonwhites and the expanding middle class but possible unskilled unemployment; supports them as part of a package. |
| Becker (1988) | Challenges the claim that sanctions must hurt poor blacks most. Argues that tailored sanctions (gold, high-tech, finance) fall mainly on whites and skilled workers and cause only moderate losses to unskilled blacks. Concedes that no stringent package is costless, since the frontline states and black South Africans would still suffer. |
| Becker (1988) | Sceptical: divestment mostly transfers assets to white South Africans, and Sullivan-principle firms' exits may leave black workers worse off. It is useful chiefly for high-tech firms, and indirectly through expectations and rand depreciation. |
| Becker (1988) | Apartheid is a compact serving virtually all white groups. Semi-skilled white workers will not yield to sanctions, but skilled workers, farmers and industrialists may erode in support as turnover costs rise and sanctions bite. |
| Becker (1988) | Criticises Spandau and Richardson for ignoring imported intermediates, foreign-exchange constraints and changes in final demand. Holds that these flaws probably understate the impact of export boycotts on whites. |
| Bell (1995) | Finds no evidence in the import-substitution indices of an exceptional drive for self-sufficiency. The economy was not unusually closed in trade or protection terms. |
| Bergholm (2009) | Holds that union action, not government initiative, drove Finland's shift to sanctions. The footnote says the author sides with Heino over Soiri and Peltola on the leverage of NGOs. |
| Bergholm (2009) | Challenges the memoir and press picture of Kuisma as the lone heroic initiator. The archives show a collective, internationally driven process, though Kuisma's resolve still mattered. |
| Bergholm (2009) | Treats the Finnish government's stance as a Janus-faced policy of condemning apartheid while trading, and presents the union action as breaking that stance. |
| Bond (2004) | States that financial sanctions and economic constraints forced white business to negotiate and brought Pretoria 'to its senses'; treats disinvestment as a central pillar of the anti-apartheid movement. |
| Bowman (n.d.) | Sides firmly with Manby, Desmond and Schwartzmann. It argues sanctions caused the 1985 financial crisis and a lasting growth shortfall, and were the main factor behind the move to negotiations. |
| Bowman (n.d.) | Presents both views, citing Lowenberg on costly capital-intensive synfuel and Schwartzmann on arms exports. It finds neither conclusive. |
| Brealey and Kaplanis (1989) | Sceptical. The direct welfare effect on South African investors is positive, so a securities boycott is unlikely to impose hardship that pressures the government. |
| Brealey and Kaplanis (1989) | Rejects coercion as a plausible mechanism but accepts that a boycott is a credible, costly signal of opposition. |
| Christopher (1994a) | Argues that diplomatic non-recognition was the symbolically most severe sanction and was widely adopted, while noting that even states imposing economic sanctions stopped short of withdrawing recognition. It does not assess economic effects. |
| Christopher (1994a) | Holds that isolation was partly self-inflicted, through the rejection of communist states and black African diplomats and the Commonwealth exit, and that the government was not greatly concerned by it. |
| Coulibaly (2005) | Finds the trade embargo a 'paper tiger' with aggregate trade unaffected, while financial isolation and disinvestment were effective and produced the macroeconomic damage. |
| Coulibaly (2005) | Argues that capital controls, the dual exchange rate and the 1985 debt standstill contained rather than caused the fall in investment, capital and output. |
| Evenett (2002a) | Finds that US sanctions had a large, robust and persistent negative effect on South African exports (about one third), while EC effects are not robust and Nordic and Japanese effects are insignificant. This is more favourable to sanctions' trade impact than Levy's 'trivial' thesis, though it does not address the effect on regime change. |
| Evenett (2002a) | Suggests trade flows need not return to pre-sanctions levels after sanctions are lifted (hysteresis), which weakens the incentive value of promised sanctions relief. |
| Evenett (2002b) | Finds measurable trade effects, but only robustly for US sanctions. EC effects are an artefact of outliers, and Nordic and Japanese effects are insignificant. This is more nuanced than Levy's claim that sanctions had a trivial role, though the paper estimates trade effects only, not political effects. |
| Evenett (2002b) | Suggests hysteresis. US exports stayed low or fell after 1991, and the EC showed only a small recovery, so removing sanctions need not restore pre-sanction trade. |
| Evenett (2002c) | Finds measurable trade effects, but concentrated in US sanctions (about a third reduction) rather than EC, Nordic or Japanese measures. The footnote on Levy's claim that sanctions played a 'trivial' role in toppling apartheid is noted but not tested, since the paper only measures trade effects. |
| Evenett (2002c) | Suggests effects endure, especially for US-bound exports, via sunk costs and new supplier relationships. EC exports show some bounce-back. |
| Giliomee (1995) | Sanctions played a definite but complex role. Financial sanctions (the 1985 bank refusals to roll over loans) were the most serious, while trade sanctions were circumvented. Disinvestment mattered chiefly by triggering the 1986 US Act, and ideological and diplomatic isolation may have been more effective than economic sanctions. |
| Gould (1981) | Ineffective without monitoring and legal force; advocates mandatory US legislation requiring recognition of black unions. |
| Harvey (1974) | Sceptical. Withdrawal would not harm the economy because real assets stay, exchange controls can block outflows, and the economy grew despite capital outflow in 1959-65. He favours pressing firms on wages, and personally favours reducing British investment for political reasons. |
| Hepple (2006) | Hepple defends the single-issue 'broad church' as the source of the AAM's success and compares it to the anti-slave-trade movement. He disagrees with Fieldhouse, who treats it as a weakness, and he criticises the militant far-left groups (CLAAG, RCG). |
| Hepple (2006) | Hepple, following Fieldhouse, holds that British governments of both parties resisted sanctions and a full arms embargo and favoured 'constructive engagement'. He ranks Cold War anti-communism above economic interest as the motive. |
| Hirsch (1989) | Argues that external economic and financial pressure, including sanctions, has pressured the regime. Financial sanctions work mainly by making business harder and costlier rather than by cutting off supplies completely. |
| Holland (1988) | Holland treats positive regional measures as a consensus-driven substitute for economic sanctions, which Britain, West Germany and Portugal resisted. He judges them modest but suitable, while acknowledging a sceptical view that they are window-dressing. |
| Holland (1989) | Sceptical. The EC investment ban was diluted by loopholes such as reinvested earnings, and companies left for profit reasons. Disinvestment sometimes preserved economic links through licensing and sales to local managers. |
| Holland (1989) | The Code improved some labour practices and spurred domestic codes, but its overall effect was marginal and it served as a justification for continued economic links. |
| Holland (1989) | Sees the Code as successful only if judged by different objectives: delaying sanctions, protecting business interests, and building common EPC policy. |
| Horrell (1968) | Records UN calls for mandatory sanctions and Western reluctance; the UN seminar declaration claimed trade with the West encouraged defiance; no evaluation of effects. |
| Horrell (1970) | Documents UN General Assembly votes urging economic disengagement from South Africa, without assessing their effect. |
| Horrell et al. (1972) | Reports both sides (Polaroid experiment, Diggs, US church pressure versus Buthelezi and Mvubelo opposing withdrawal) without taking a position. |
| III et al. (1995b) | Skeptical on the financial channel. Divestment announcements produce no significant stock-price reaction, because other investors buy the shares and expected cash flows are unchanged. Few targeted firms announced changes. The authors allow that media attention may still harm a firm's image. |
| III et al. (1995b) | Treats both the classic (Alchian/Manne) and Fama views as implying that a negative price reaction can motivate managerial change. The classic view is seen as more immediate and easier to observe. |
| John (2000) | Argues that financial sanctions, especially the 1985 loan withdrawal, were an important lever that created a 'siege economy' and helped force De Klerk to negotiate. Concedes that the precise impact is hard to measure and that campaign influence is hard to separate from normal commercial considerations. |
| John (2000) | Treats Barclays' 1986 sale as commercially motivated but shaped by the damage the boycott did to its British retail business. Treats Standard Chartered's exit as less campaign-driven than Barclays'. |
| Kirsten et al. (2007) | Treats sanctions and isolation as a secondary influence. Sanction-busting costs and targeted export campaigns (Outspan oranges) hit fruit-exporter returns, but domestic support policy and fiscal and macroeconomic pressure drove the timing of reform. |
| Levy (1999a) | Sceptical: the trade sanctions' contribution was probably trivial and possibly counterproductive; the role was mainly psychological and cannot be fully excluded. |
| Levy (1999a) | The capital reversal was far more painful than trade sanctions, but it was driven by private lenders responding to unrest and instability, so it cannot be counted as evidence of sanctions' efficacy. |
| Levy (1999b) | Sceptical. Government-imposed trade sanctions played no significant positive role and may have delayed change. Private financial and disinvestment actions mattered more but cannot be counted as evidence for public sanctions. |
| Levy (1999b) | Uses their framework but disputes the 'contribution' score for South Africa. He cites Morgan and Schwebach (1997) as arguing that their success rate is overstated. |
| Lowenberg (1997) | Sceptical: sanctions were partly an effect of South African turmoil. Financial withdrawal was the most damaging channel, and it was a market response to risk. Sanctions' main effect was to push the state into inefficient self-sufficiency projects such as SASOL. Apartheid would have collapsed without them. |
| Lundahl (1984) | Sceptical of sanctions as an 'infallible weapon'. Boycotts shift incomes among white groups, and a boycott may be preferred to reducing discrimination. Effective short-run pressure would need to target agriculture, with industrial sanctions more effective in the longer run. |
| Major (2005) | Argues the TUC was cautious and 'led from behind', favouring fraternity with white labour over African unions. This made it largely ineffective and left African unionists to apartheid. |
| Major (2005) | Shows the TUC doubted that boycotts would work and feared job losses. It favoured a voluntary consumer boycott and treated sanctions as a government responsibility, deferring to the Labour Party. |
| Major (2005) | Argues fear of association with Communism (Sachs, SACTU, WFTU) was a persistent brake on TUC initiative, unlike the American CIO. |
| Mariotti and Fourie (2014) | They pose the question of whether sanctions force regime change or strengthen the oppressor. They report Kaempfer and Lowenberg's conclusion that the domestic costs of running apartheid, rather than sanctions, made the system untenable. |
| Massie (1997) | Strongly pro-effectiveness: argues that economic pressure imposed a stiff tax on the economy, destroyed business confidence, split the Afrikaner community and aided peaceful transition, and that predictions of intensified Afrikaner resolve were wrong. |
| Massie (1997) | Critical of Crocker's constructive engagement as ineffective and slow to change; documents its collapse after 1985-86 and the Congress override of Reagan's veto. |
| Massie (1997) | Sees the Principles as useful insider pressure but insufficient; notes activists' critiques, and Sullivan's 1987 shift to total withdrawal. |
| Miller (2003) | Sanctions had some effect, with bank loan withdrawals and public or private pressure stronger than government-ordered trade sanctions. The author gives internal resistance greater weight and calls the exact effect unmeasurable. |
| Miller (2003) | Treats the Sullivan Principles and constructive engagement as insufficient because they dealt only with workplace treatment. Sees Sullivan's 1987 call for full withdrawal as a sign of their failure. |
| Miller (2004) | Holds that sanctions had some effect, with bank loan withdrawals in 1985 the strongest weapon, but that internal resistance was more significant. It says a precise attribution is impossible. |
| Miller (2004) | Treats the Sullivan Principles as inadequate because they addressed only workplace treatment and not political rights. It notes Sullivan himself called for full withdrawal by 1987. |
| Miller (2004) | Following Rodman, argues that voluntary private pressure worked better than government mandates, which firms evaded. |
| Minter (1986) | Strongly pro-sanctions: judged by cumulative, long-term and indirect effects, sanctions have a respectable record and comprehensive measures could bite; partial sanctions are only modest in effect. |
| Minter (1986) | Rejects the dichotomy as false; Pretoria lacks the will to negotiate until weakened by sanctions and internal pressure. |
| Minter (1986) | Short-term hardship for blacks acknowledged, but whites probably hurt more proportionately; the front-line states back sanctions despite vulnerability. |
| Minter (1986) | Closer to the revisionist side: white business, notably Anglo American built on cheap black labour, profited from the system and favours reform only under threat; liberal patience is a 'broken record'. |
| Minter (1986) | Rejects it as a myth; pressure can fragment Afrikaner and white unity. |
| Nishiura (2006) | Argues that sanctions and disinvestment fostered concentration, since local business groups with ample capital became buyers of withdrawing foreign firms. |
| Nishiura (n.d.) | Sanctions stimulated concentration because local conglomerates, with large funds, bought out departing foreign firms. |
| Overseas Development Institute (1986) | Financial sanctions (bank credit withdrawal) and any action to lower the gold price matter far more than trade or investment bans, which are limited in scope or circumventable. |
| Overseas Development Institute (1986) | Evasion is possible but costly. Oil import premiums, storage, exploration and SASOL investment imposed large costs even though oil kept arriving. |
| Overseas Development Institute (1986) | The rand fall and the gold price rise gave short-term relief. The paper doubts they will last, since medium-term forecasts point to flat or falling prices and oversupply of other minerals. |
| Overseas Development Institute (1986) | Sanctions would raise black unemployment in absolute terms, especially through export-sector job losses, but the white-dominated modern sector would lose proportionately more. The long-run low-growth trend matters more than marginal sanctions effects. |
| Rex (1975) | He is sceptical that the policy studies can show which strategy is superior, given the lack of experimental control. |
| Rich (1990) | Sceptical of the reviewed texts. They offer no graduated link between pressure and specific policy changes, and may provoke entrenchment. He leans towards the view that the threat of sanctions, or the climate it created, mattered more than the sanctions themselves. |
| Rich (1990) | Reports the SAIRR liberal view that recession and lack of investment could leave a crippled economy for an ANC government to inherit, and notes that the reviewed texts do not engage with it. |
| Rodman (1994) | Argues that MNCs and NGOs were autonomous actors, and that private actors rather than states delivered the most damaging sanctions. Public authority still mattered indirectly by shaping risk perceptions. |
| Rodman (1994) | Rejects the reading of the 1985 bank withdrawal as a vindication of constructive engagement. It sees the credit boycott as driven by anticipated sanctions, the loss of a US-backed IMF safety net, and anti-apartheid pressure, not just market risk. Disinvestment itself was largely cosmetic. |
| Rodman (1994) | Holds that external risk alone cannot explain the scale of retreat. Anti-apartheid pressure, the 'hassle factor', municipal contract rules and the threat of future sanctions amplified market signals. |
| Rodman (1995a) | Partially confirms the hegemonic decline model: the state cannot command affiliates. Argues the model overstates corporate autonomy, since the state can shape firms' perceptions of risk and induce compliance. |
| Rodman (1995a) | Treats the CAAA as leaky in law, but argues that the credit cutoff, disinvestment and the cost of sanctions (market pressures amplified by Congress and activists) did weaken South African creditworthiness. Constructive engagement and the 1982 IMF loan had earlier encouraged lending. |
| Rodman (1995a) | Argues disinvestment often imposed little cost on white South Africans, because firms sold to local management and kept licensing ties, and it reduced social accountability. |
| Rodman (1995b) | Partly confirms the decline thesis (no extraterritorial control, no persuasion) but argues it overstates corporate autonomy, since the state can shape corporate risk perceptions and so induce voluntary compliance. |
| Rodman (1995b) | Market pressures (unrest, recession, credit risk) were primary, but congressional action and subnational anti-apartheid pressure amplified them by eroding business confidence, removing the IMF safety net and imposing direct costs. |
| Rodman (1995b) | Sceptical of its direct impact: departing firms sold to local managers and kept licensing ties, imposing little cost on white South Africans and reducing social accountability. |
| Rodman (1995b) | Describes Congress's shift from constructive engagement to linkage conditioned on reforms as a real change that altered creditor and investor expectations. |
| Sabbagh (1968) | Briefly suggests in a footnote that boycotts have not worked because they hurt the Bantu they are meant to help. |
| Stemmet (2002) | Treats sanctions and the 1985 bank withdrawals as the decisive external pressure that made the status quo unaffordable. Notes they did not collapse the economy in the short run; their weight lay in lost investment and future growth. Reports the opposing anti-sanctions arguments (Suzman, Reagan, Thatcher, Walters) at length and sympathetically. |
| Stemmet (2002) | Following Sampson, concludes that political pressure and 'hassle' outweighed commercial calculation in the banks' withdrawal. |
| Steward (2004a) | Argues from the perpetrator-regime side that sanctions were one factor to be weighed but not the main driver; economic and social change and the end of the Cold War mattered more. Sanctions were effective only where core interests were not threatened. |
| Steward (2004a) | Concedes they cut growth by roughly 1.5% a year and forced costly strategic investment, but stresses unintended benefits such as SASOL, armaments and oil reserves, and the 1985 banking crisis as market-driven rather than a sanction. |
| Steward (2004b) | Sanctions cut growth by about 1.5% a year and forced costly strategic investments, but also spurred import substitution. The 1985 debt crisis was market-driven rather than a sanction. |
| Teoh et al. (1999) | Sceptical. Finds no discernible negative announcement effects on US banks, on exposed US firms, on divesting firms or on South African financial markets. It concedes that sanctions may have raised moral awareness. |
| Teoh et al. (1999) | Finds little price effect from institutional withdrawal or return, consistent with highly elastic demand. |
| The Liberation Struggle in South... (n.d.) | No explicit position. It lists the sequence of sanctions, bank withdrawals and divestment (including Thatcher's opposition and Japanese and Taiwanese trade growth), which gives context for the debate but does not weigh their effect. |
| Truth and Reconciliation Commission, Reparation and Rehab... (1998) | Holds that Swiss banks and other lenders, notably through the 1985 debt standstill and continued gold imports, helped prolong apartheid and gave the state a breathing space. |
| Van Vuuren (2006) | Argues that embargoes forced purchases through middlemen at a premium, creating opportunities for graft and imposing large costs on the economy. |
| Wagner et al. (1984) | Argues against Rudd, Calderwood and Schwartz. It says restrictions have little effect only on funds of about $50 million or less, and that large funds face higher risk and costs and may need to restructure their portfolios. |
| Wagner et al. (1984) | The 152 South African-linked stocks returned less than their replacements over five years. The authors attribute the gap to the small-firm effect, not to a benefit of divesting, and say higher returns carry higher risk. |
| Washington Office on Africa (1985) | The factsheet comes from a sanctions-supporting lobby. It records France's investment cut-off and the Shultz defence of constructive engagement, but offers no analysis of effectiveness. |
| Wright and Ferris (1997) | Sceptical of divestment: argues it hurt shareholders and was probably not beneficial to black South Africans, and that continued US business engagement helped drive reform and the end of sanctions. |
| Wright and Ferris (1997) | Supports the agency view: negative announcement returns are read as managers responding to political pressure rather than to shareholder value. |
