Oil Price Volatility and Inflation Data Impact Treasury Bonds

U.S. Treasury bonds experienced volatility between August 11 and 12 as investors balanced domestic inflation data against geopolitical instability in the Middle East. On Tuesday, the benchmark ten-year note yield dipped to 4.684 percent, though buying interest was limited by rising crude oil prices. This volatility stems from the closure of the Strait of Hormuz, which Mohsen Rezaei, Secretary of Iran's Supreme National Security Council, stated will not reopen until Tehran's conditions are met.

On Wednesday, bonds initially gained strength following a Labor Department report showing July consumer price inflation in line with estimates. Consumer prices rose 0.1% and core prices increased 0.2%, with the annual inflation rate holding at 3.4%. These figures initially pushed the ten-year note yield to a low of 4.646%.

However, these gains evaporated by the end of the session. Investors grew concerned that elevated crude oil prices and ongoing tensions in the Middle East could reaccelerate inflation, erasing early progress. The ten-year note yield ultimately closed Wednesday at 4.682%, ending the session roughly flat.
