30-Year Treasury Yield Hits Highest Since 2007 as Iran Ceasefire Expires

The 30-year Treasury yield closed at its highest since 2007 on August 18, 2026, with the 10-year near 5.3%, per WSJ and Reuters. The expired 60-day U.S.-Iran ceasefire lifted oil prices, feeding inflation pressure into long-dated bonds. Tech and chip stocks dragged Wall Street to two-week lows as higher yields compressed growth valuations.
