U.S. Treasury yields climbed on Monday as investors sought clarity on the status of peace talks between the United States and Iran, which led to a surge in oil prices. Conflicting reports about the negotiations caused market volatility, with yields initially rising sharply before easing after U.S. President Donald Trump indicated that talks were ongoing.
The yield on the benchmark U.S. 10-year Treasury note increased by 2 basis points to 4.473%, having reached 4.518% earlier in the day. This movement followed a report from Iran's Tasnim news agency suggesting a halt in message exchanges between Tehran and Washington due to regional conflicts. However, Trump's statement on social media countered this, calming market fears temporarily. The U.S. crude oil price rose 5.39% to $92.07 per barrel, while Brent crude increased by 4.2% to $94.95 per barrel.
The two-year U.S. Treasury yield, closely tied to Federal Reserve rate expectations, gained 3.7 basis points to 4.051%, peaking at 4.09%, the highest since May 22. Persistently high crude prices, with the Strait of Hormuz remaining closed, have shifted market expectations for a Federal Reserve rate hike, now seen as more likely at the December meeting.

Yields briefly extended gains after the Institute for Supply Management reported its manufacturing PMI rose to 54.0 in May, surpassing economist forecasts. Meanwhile, the Commerce Department noted a 0.4% increase in construction spending, exceeding expectations. Despite these positive economic indicators, the geopolitical tensions overshadowed market sentiment.

Background
The geopolitical tensions between the U.S. and Iran have been a significant factor influencing market dynamics, with previous optimism about a potential peace agreement leading to a decline in yields last week. The ongoing situation continues to impact investor sentiment and market expectations.
Looking ahead, investors will closely monitor developments in U.S.-Iran relations and their implications for global oil prices and Federal Reserve policy. The evolving geopolitical landscape will likely remain a key driver of market movements in the coming weeks.
