What the policy did

Annexed to the Maastricht Treaty as Protocol No. 4, the Statute of the European System of Central Banks and the European Central Bank entered force with the ECB's establishment on 1 June 1998. It enshrined price stability as the primary mandate, prohibited monetary financing of governments (Article 123 TFEU), and made the ECB Governing Council operationally independent of national governments — a Bundesbank-modelled architecture for the single currency.

Policy-content fingerprint — what this policy moved, on which axes

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.

intended
central bank independence
monetary.central_bank_independence
De jure and de facto independence of the central bank from fiscal authority. Per D.1.5 scope, one of the framework's defensible monetary positions.
increased · weak
greater independence (legal, operational, personnel)
Treaty-level independence and a no-bailout/no-monetary-financing clause locked in central-bank autonomy.
spending level
fiscal.spending_level
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
decreased · weak
lower spending share
The price-stability mandate disciplined fiscal policy by removing recourse to inflationary financing.
