Net Liquidity Multi-CB (Fed + ECB + BoJ)TRINITY EXCLUSIVE
Aggregated central bank net liquidity in USD billions: Fed Net Liquidity (Federal Reserve balance sheet (total assets) - TGA - RRP) + ECB Total Assets + BoJ Total Assets, all converted to USD via daily FX rates.
Trinity exclusive model
This metric is a proprietary Trinity Insights model. Its formula, inputs, weights and parameters are NOT disclosed. The page documents only the output (bounded scale, interpretation zones, historical context). Access to the score and its time series is via the REST API and the MCP server, subject to the required tier.
What is it?
Net Liquidity Multi-CB sums the net liquidity contributions of the three largest central banks in the developed world, all expressed in U.S. dollar billions. The Federal Reserve component subtracts the Treasury General Account and Reverse Repo balances from total Fed assets (Federal Reserve balance sheet (total assets)), capturing the truly available liquidity in the U.S. banking system. The ECB component adds total Eurosystem assets converted to USD via daily ECB reference rates. The BoJ component adds total Bank of Japan assets converted to USD via daily Tokyo fixings. The result is a single metric that tracks the combined macro liquidity of the largest reserve-currency-issuing central banks.
How to read
The trend matters more than absolute levels. A rising line indicates aggregate central bank balance sheet expansion (quantitative easing, reserve creation, asset purchases). A falling line indicates aggregate balance sheet runoff (quantitative tightening, asset sales, reserve drain). Plateau periods reflect coordinated policy holds. Divergences between Fed and other central banks are visible in the decomposition sub-pane: when Fed shrinks while ECB and BoJ expand, the Multi-CB total can remain neutral despite headline Fed tightening, providing a more accurate read of global liquidity than Fed-only metrics.
Key zones
• Sustained rising trend with steep slope: aggressive coordinated easing - historical post-crisis stimulus phases • Rising trend with moderate slope: normal expansion - productive credit creation period • Plateau: coordinated holds, often late-cycle equilibrium • Falling trend with moderate slope: coordinated normalisation - restrictive but orderly • Sustained falling trend with steep slope: aggressive coordinated tightening - historical late-bull / early-bear contexts
What to observe
• Trend reversals are more meaningful than absolute levels - watch the slope rather than the value • Decomposition divergences (e.g., Fed shrinking + ECB expanding) often precede currency moves • Periods where all three are growing simultaneously are historically rare and bullish for risk assets • Periods where all three are shrinking simultaneously are historically associated with major risk-off events • Watch for liquidity arbitrage: when one central bank dominates, the others often respond within 6-12 months
Historical context
Combined central bank net liquidity expanded sharply during the post-Lehman recovery (2009-2014) as the Fed launched QE1/QE2/QE3, the ECB initiated APP, and the BoJ rolled out QQE. The 2015-2018 period saw divergence: Fed normalising while ECB and BoJ continued expansion. The COVID response in 2020 produced the largest synchronised expansion in history. The 2022 tightening cycle marked the first synchronised contraction since 2008. The series naturally aligns with major liquidity-driven risk asset cycles.
Expert notes
⚠️ Trinity Exclusive Model - Multi-CB aggregation methodology proprietary to Trinity. Standard practice in industry research limits liquidity tracking to a single central bank (typically the Fed) or simple summation without FX conversion. Trinity's daily FX conversion via ECB Frankfurter rates ensures cross-currency comparability. PBoC excluded from MVP due to data availability and renminbi regime differences; future versions may incorporate PBoC reserves once a stable data pipeline is established. Cross-rubric position: distinct from individual central bank balance sheet metrics already available in Macro v1 - this composite adds value by enabling regime-level analysis.
Common mistakes to avoid
• 'Multi-CB rising = guaranteed bullish' - The series is a leading regime indicator with multi-month lags before transmitting to risk asset prices. • 'Three central banks suffice for global liquidity' - The PBoC, BoE and SNB are non-trivial contributors. The MVP scope captures the dominant 80% but is not exhaustive. • 'USD conversion distorts the reading' - Currency conversion at daily rates is the standard institutional approach for cross-region liquidity analysis. Without conversion, comparisons are meaningless.
