European ERM crisis and Britain’s Black Wednesday
1992.09.16
Despite a large-scale defense of sterling, the United Kingdom suspended participation in the Exchange Rate Mechanism.
Shows the United Kingdom’s suspension of ERM participation as the representative event, rather than the entire European crisis.
Conditions at the time
German interest rates diverged from the policy needs of countries with weaker economies.
How events unfolded
On 9/16, after intervention and announcements of rate increases, the United Kingdom suspended ERM participation.
Stakeholders and impacts
The UK government, the Bank of England and other European monetary authorities responded to exchange-rate pressure.
Information available at the time
The Bank of England’s contemporary report explained the conflict between domestic policy objectives and exchange-rate commitments.
Findings confirmed later
After leaving, the United Kingdom gained room to adjust monetary policy.
Alternative interpretations and limitations
The UK suspension date does not mean every European country left the framework or that the crisis ended.
Source-based context and interpretation
The Bank of England's quarterly account records large sterling purchases and announced defensive rate increases failing to preserve the exchange-rate floor. ERM membership constrained UK easing through German rates; suspension allowed a rate reduction and depreciation to ease monetary conditions. ASSETCASTING interpretation: Failure to defend an exchange-rate commitment can coexist with greater domestic-policy flexibility. Examine the conflict between the parity and domestic objectives rather than only speculators' success; later recovery cannot be attributed solely to suspension.
