Direction of monetary-base expansion decisions relative to trend. Separate from fiscal.transfer_expansion even when correlated.
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.
Federal Reserve Quantitative Easing 1 (QE1), announced 25 November 2008 and expanded 18 March 2009, comprised large-scale asset purchases (LSAP) of approximately USD 1.25 trillion in agency-MBS, USD 175 billion in agency debt, and USD 300 billion in Treasury securities under FOMC authority. The intended effect was to repair the impaired mortgage-finance market post-Lehman, compress long-term Treasury and MBS yields, support housing-market recovery, and provide monetary stimulus once the federal funds rate had reached the zero lower bound — establishing unconventional monetary policy as a mainstream Fed tool.
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.
