The US 10-year Treasury yield dropped below the 4.5% threshold on Monday, marking a sharp repricing of geopolitical risk following the announcement of a ceasefire agreement between the United States and Iran.
The move underscores how quickly bond markets are adjusting to the prospect of lower energy costs and reduced inflationary pressure from the Middle East.
Despite the geopolitical thaw, interest-rate markets are pricing in a prolonged pause from the Federal Reserve.
A potential peace agreement in Iran is currently viewed as insufficient to tame the broader inflation pressures that keep policymakers on hold.
The disconnect between the headline geopolitical relief and the stubborn underlying price data is keeping the Fed's hands tied.
The ceasefire announcement triggered a broad sell-off in equities and a rally in safe-haven assets, with the Treasury yield decline serving as the primary signal of shifting market sentiment.
