Treasury yields dropped across all maturities, with declines ranging from four to six basis points. This decline reversed the increases seen on Friday, when the US benchmark crude futures contract closed near $100 per barrel. On Monday, after briefly exceeding this level, crude prices sharply fell more than 5%, settling under $94 a barrel, which eased concerns about inflationary pressure. The decrease in oil prices also led to a significant rally in bonds, particularly US Treasuries.

The drop in oil prices was primarily driven by the US pausing its two-week bombing campaign against Iran on Friday, which prompted Iran to suspend its retaliatory attacks. This de-escalation in the Middle East conflict revived hopes for diplomacy and boosted market sentiment, leading to a "risk-on" environment. Investors became more optimistic, reducing demand for safe-haven assets. This also cooled expectations for aggressive rate hikes from the Federal Reserve, as lower energy prices could mitigate inflation.

In related market movements, crude oil prices tumbled over 5% at the start of the week, with Brent crude futures falling $4.89, or 5.05%, to $91.89, and West Texas Intermediate (WTI) crude futures trading 5.36% lower at $84.52 per barrel. The US Dollar, typically a safe-haven currency, retreated from its monthly high. US stock futures, including the Dow Jones Industrial Average, S&P 500, and Nasdaq 100, all traded higher on the news. Asian markets generally opened positively, with the Indian Sensex and Nifty 50 showing strong gains of 1.02% and 0.96% respectively. Japan's shorter-dated bond yields also slipped, further reflecting the cooled inflation concerns.
