Frequently Asked Questions (FAQSchema Verified)
Why did the FOMC taper Quantitative Tightening (QT) while rates remain restrictive?▼
Tapering the pace of SOMA Treasury redemptions prevents sudden money-market rate spikes similar to September 2019 by allowing non-reserve liabilities and Treasury General Account (TGA) swings to clear smoothly as ON RRP balances approach structural floors.
How does the SOFR-EFFR spread signal repo market funding pressure?▼
When primary dealer balance sheets become saturated with Treasury collateral, overnight repo borrowers bid up SOFR relative to unsecured EFFR. A sustained spread above +10 bps outside quarter-end dates indicates scarce reserve distribution.
What reserve threshold does the New York Fed consider transitionally ample?▼
Desk surveys indicate aggregate commercial bank reserves between $3.0 trillion and $3.25 trillion (roughly 10.5% to 11.5% of nominal U.S. GDP) represent the boundary between abundant and ample liquidity.
