Has shrinking the central bank balance sheet actually reduced bank reserves?
Core argument: Bank reserves at the Federal Reserve stand near 2022 levels despite quantitative tightening, as reserves shift between the reverse repo facility and the Treasury General Account even while the overall balance sheet shrinks.
The Fed operates an “ample reserves” framework, but is not sure how to view non-reserve liabilities. Under the framework, the Fed primarily adjusts monetary policy through changes in short-term interest rates and provides the banking system with a bit more reserves than it actually needs. Reserves are just deposits commercial banks hold at the Fed. Although QT has been shrinking the overall size of the Fed’s balance sheet, the composition of the Fed’s liabilities is dynamic. Reserves can move into the RRP and into the TGA (and vice versa), so reserve levels today are around 2022 levels despite QT. Fed officials unanimously note that reserve levels are far above ample, but have diverged on how they view changes in the RRP. These differences have led to different potential QT timelines.
