Foreign Central Banks Dump $50B in USTs, 10-Year Yield Spikes 25bps; Dealers Swamped, Fed QE Eyed

Foreign Central Banks Dump $50B, Breaking Dealer Capacity Foreign central banks sold $50 billion in U.S. Treasuries this week, the largest weekly liquidation since March 2020, according to Federal Reserve custody data. The selling, led by Asian and Middle Eastern reserve managers, pushed the 10-year yield up 25 basis points to 5.38%, the highest since 2007. Primary dealers absorbed the supply, but their net Treasury positions have ballooned to a record $180 billion, up from $110 billion a month ago, according to New York Fed data. The dealer community is now signaling it cannot absorb another wave without a significant price concession or Fed intervention.

Why Is the Fed Raising Interest Rates? The Fed is not raising rates; in fact, the market-implied probability of a hike at the October 31 meeting is only 6.5%, according to Polymarket, where 'No change' holds a 93.5% probability. The confusion stems from the recent spike in long-term yields, which is driven by foreign official selling and term premium repricing, not by Fed policy. The Fed's current target range is 4.50%-4.75%, unchanged since July. However, the sharp rise in long-end yields is doing the tightening for the Fed, effectively raising borrowing costs across the economy.

Why Is the Federal Reserve Important? The Federal Reserve is important because it controls the supply of the world's reserve currency and sets the benchmark for global borrowing costs. In the current episode, the Fed's role as a backstop for the Treasury market is being tested as foreign selling overwhelms dealer capacity. The Fed's emergency QE consideration underscores its critical function in maintaining market functioning. As the lender of last resort, the Fed may need to step in to prevent a self-reinforcing selloff that could spill over into other markets.

The Fed Today News: Polymarket Consensus and Market Implications Despite the turmoil in the long end, prediction markets show remarkable calm about the Fed's upcoming decision. Polymarket traders assign a 93.5% probability to no change in the fed funds rate on October 31, with only 6.5% odds of a 25bps hike. The 24-hour trading volume of $3.9 million on this market indicates active speculation but strong consensus. The market-implied path contrasts with the Fed's official communications, which have emphasized data dependence. The divergence suggests that traders believe the Fed will prioritize financial stability over inflation concerns, especially given the stress in the Treasury market. The total volume of $61.3 million on this market highlights the growing importance of prediction markets as a real-time gauge of monetary policy expectations.

Key Data Metrics - 10-year Treasury yield: 5.38% (+25bps this week) - Foreign official UST sales: $50 billion (weekly, highest since March 2020) - Primary dealer net Treasury positions: $180 billion (record high) - Polymarket implied probability of no Fed hike: 93.5% - Polymarket 24-hour volume: $3.9 million

What's Next The Fed's emergency QE consideration is a sign of the times. If foreign selling persists, the Fed may announce a new purchase program as soon as next week. For investors, the key is to watch dealer inventories and auction demand. A failed auction could trigger a sharp repricing of rate expectations and force the Fed's hand. In the meantime, the 10-year yield at 5.38% offers value for long-term investors, but the risk of further volatility remains high.
