Core Viewpoint - The U.S. short-term financing market is showing signs of liquidity tightening again, raising doubts about the effectiveness of recent Federal Reserve interventions. The rise in key interest rate indicators suggests speculation that the Fed may be forced to expand its balance sheet again, interpreted by some as a new round of quantitative easing (QE) [1][3]. Group 1: Market Dynamics - The secured overnight financing rate (SOFR) has recently surged, widening the spread with the Fed's interest on reserves (IOR) to 8 basis points, indicating a return to a tense financing environment [1][4]. - Following the Fed's decision to end quantitative tightening (QT) at the end of October, the banking system's reserves may be sliding towards "scarcity" levels, increasing pressure for further Fed action [3][9]. - The rebound in SOFR and tri-party repo rates above the IOR suggests that bank reserves have moved from "ample" to "scarce" levels [4][10]. Group 2: Federal Reserve's Position - Fed officials have indicated that reserves are no longer "ample," hinting that "reserve management purchases" may be the next step in normalizing the Fed's balance sheet [6][11]. - The timing for the Fed to expand its balance sheet will depend on the relationship between the effective federal funds rate (EFFR) and the IOR, with expectations that the EFFR-IOR spread may narrow by year-end [8][9]. - The continued use of the standing repo facility (SRF) is seen as a clear signal of scarce reserves, with recent data showing a resurgence in daily usage of the SRF tool [10][11]. Group 3: Current Reserve Levels - U.S. bank reserve levels have dropped to their lowest point in five years, indicating a challenging transition from "ample" to "scarce" reserves, with market signals suggesting potential volatility in this process [11][12].
