The Worst 5-Year Auction in Years - Foreign Buyers Retreat

A significant surge in bond market volatility occurred this week, triggered by hotter-than-expected Purchasing Managers Index (PMI) data. This economic signal sparked a massive sell-off, driving the 5-year Treasury yield up by nearly 17 basis points—one of the largest moves in the post-COVID era. A subsequent 5-year Treasury auction saw the lowest demand since 2020, characterized by a weak 2.2 bid-to-cover ratio and a notable retreat by indirect bidders, typically representing foreign central banks. Consequently, price-sensitive direct bidders demanded a 3.1 basis point tail to absorb the supply. This market frenzy shifted Federal Open Market Committee (FOMC) expectations, with traders increasing the probability of an October rate hike from 50% to 75% and beginning to price in an additional hike for December. These developments underscore a volatile acceleration in the long-term trend of rising yields and tightening monetary policy expectations.
