UK entry into the European Exchange Rate Mechanism on 8 October 1990 at central rate DM 2.95/£, used as a counter-inflation anchor under Chancellor John Major. The peg collapsed on Black Wednesday (16 September 1992) when speculative attacks forced sterling out of the ERM despite emergency rate hikes from 10% to 15% and large-scale Bank of England intervention. The episode discredited the fixed-rate framework and paved the way for inflation targeting in 1992.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
