What the policy did

Abolition of exchange controls that had been in place since 1939 under the Exchange Control Act 1947. Removed restrictions on UK residents' foreign-currency and overseas investment holdings. Seen retrospectively as the single most consequential financial- liberalisation act of the Thatcher era, preceding Big Bang by seven years and enabling City of London's transformation into global financial centre.

Estonia adopted among the most radical market-liberalisation packages of any post-Soviet state — flat tax (26% universal rate, 1994), currency board (EEK pegged to DM/EUR, 1992), rapid privatisation, unilateral free trade, and minimal capital controls — and by 2007 had recovered to Soviet-era GDP per capita levels and substantially exceeded them, while Belarusian and Ukrainian peers had not recovered comparably.

Australia’s long expansion after the Hawke-Keating reforms (1983–1996) — including tariff cuts, financial deregulation, competition-policy introduction, and fiscal consolidation — is better predicted by market liberalisation than by sector-specific state direction.

Singapore's long-run prosperity and frontier convergence are better predicted by extreme trade openness, strong rule of law, competitive product and services markets, and high economic freedom than by state ownership or industrial targeting alone.

The African Continental Free Trade Area (AfCFTA), with trading formally commencing 2021-01-01, has not yet produced a measurable acceleration in aggregate African trade-openness ratios over the 2021-2024 window relative to a synthetic-control donor pool of non-AfCFTA emerging-market regions, because of slow tariff- schedule ratification, COVID-19 trade disruption, and weak cross-border infrastructure.
