What the policy did

In response to the global financial crisis the Bank of Japan cut the uncollateralised overnight call rate from 0.5% to 0.1% in two steps (October and December 2008), expanded outright JGB purchases, and introduced complementary deposit facility, CP/corporate bond purchase and US-dollar funds-supplying operations. The actions stabilised yen money markets and supported bank balance sheets through the post-Lehman dislocation.

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
spending level
fiscal.spending_level
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
increased · weak
higher spending share
BOJ purchases absorbed JGB issuance, indirectly enabling larger fiscal spending packages.
transfer expansion
fiscal.transfer_expansion
Size of cash and near-cash transfer programmes (unemployment benefits, means-tested assistance, universal child benefits). Architecturally distinct from forced-saving schemes — see condition welfare_architecture.
increased · weak
larger transfer footprint
Cheaper financing for the state supported expansion of crisis-era household and firm transfers.
sectoral subsidy
fiscal.sectoral_subsidy
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
increased · weak
expanded sectoral subsidies
CP/corporate-bond purchases functioned as targeted credit support to manufacturing and finance.
monetary expansion direction
monetary.monetary_expansion_direction
Direction of monetary-base expansion decisions relative to trend. Separate from fiscal.transfer_expansion even when correlated.
increased · weak
expansionary (balance sheet, rates lower than Taylor)
Rate cuts and JGB/CP purchases jointly extended monetary easing through the GFC.

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?".

Truss 2022 mini-budget shows that unfunded fiscal expansion above the ZLB triggers sharp bond-market and currency responses through expected-inflation and risk-premium channels.

Across the 2008-2014 ZLB era and the 2020-2021 pandemic-response window, large-scale de-facto monetary finance of fiscal expansion in the US, Japan, and the Eurozone did not produce headline-CPI inflation consistent with naive quantity-theoretic monetisation predictions: cumulative central-bank balance-sheet expansion exceeded 15% of GDP while CPI YoY remained below 3% in each economy across both windows.

Post-2008 large-scale asset purchase programmes by the Federal Reserve, ECB, Bank of England, and Bank of Japan produced a measurable divergence between asset-price inflation (equities and residential real estate) and headline consumer-price inflation until roughly 2021.
