The past few days have seen significant fluctuations in the US financial markets, particularly in the Secured Overnight Financing Rate (SOFR) and General Collateral (GC) repo rates. This spike in SOFR rates indicates a potential strain in USD liquidity, with USD rising and VIX staying elevated. The Federal Reserve's recent decision to cut interest rates by 50 basis points may have been influenced by banks' efforts to manage their debt, as evidenced by a sharp decline in outstanding loans from the Bank Term Funding Program (BTFP). Additionally, the Federal Reserve's balance sheet has decreased by $66 billion in September, continuing its quantitative tightening measures, which have reduced the balance sheet by $1.92 trillion from its peak. The Reverse Repurchase Agreements (RRPs) at the New York Fed are also trending down and may fall below $300 billion soon.
