According to Woofun AI, the $202 billion Treasury coupon settlement scheduled for execution by the U.S. Treasury on September 30 has become a focal point for markets. This massive capital flow not only tests the overnight funding conditions at quarter-end, but may also indirectly affect the Bitcoin market through interest rate volatility, sparking investor vigilance against unexpected price swings.
Looking at the specific structure of the debt issuance, this settlement involves several key maturity varieties. The U.S. Treasury has arranged to reopen 10-year inflation-protected securities, 2-year notes, 5-year notes, and 7-year notes, all set to complete trading on that day. The public face values for each variety are set at $19 billion, $69 billion, $70 billion, and $44 billion respectively, bringing the total scale to $202 billion. At the same time, $143.58 billion in publicly held coupon-bearing debt will mature on the same day, resulting in a net new face value of $58.42 billion. It is worth noting that this net new figure only reflects the amount of securities that still need to be issued after maturities, and does not directly equate to actual cash outflows or a reduction in bank reserves. The final actual cash flow situation will also be influenced by multiple factors including auction prices, inflation adjustments, and the pace of Treasury spending. Additionally, bonds auctioned before quarter-end are scheduled to settle on October 1, and therefore are not included in the above coupon settlement amount.
In the face of potential liquidity pressure, the central bank's response strategy and the current interest rate situation have become key observation indicators. The New York Federal Home Loan Bank plans to execute approximately $15.6 billion in reinvestment purchases between September 15 and October 14, but has explicitly suspended operations specifically designed to manage bank reserves. This means the Federal Reserve is still replacing maturing mortgage-backed securities principal with Treasury bills, rather than actively increasing reserves. Roberto Perli of the New York Federal Home Loan Bank emphasized on September 22 that bank reserves are currently ample and funding markets remain orderly. As a comprehensive indicator measuring the cost of overnight Treasury-backed borrowing, SOFR recorded a value of 3.88% on September 24. Data compiled by Woofun AI shows that SOFR stood at 3.85% on September 18 and September 21, consistently below the 3.90% rate the Federal Reserve pays on bank reserves. Although SOFR shows an upward trend, institutions still believe market funding conditions are stable. If SOFR only briefly rises at quarter-end and then quickly falls back, its signal strength will be weaker than a sustained pressure situation above the reserve rate.
In verifying the transmission mechanism to the Bitcoin market, traders are closely monitoring whether the funding conditions of perpetual contract futures deteriorate and whether the futures market premium narrows. Declining market depth, reduced leverage, and spot weakness can serve as corroborating indicators. Recent reports from CryptoSlate point out that the reduction in derivatives positions before settlement mainly stems from changes in U.S. Treasury bond yields, rather than repo operations. If repo rates and Bitcoin funding conditions remain stable after settlement, then the expected transmission effect lacks supporting evidence. Even if a decline in Bitcoin prices coincides with a rise in SOFR, the mere overlap in timing cannot establish a causal relationship between the two; rational analysis requires ruling out other confounding variables.
