The 10-Year Treasury yield is closing in on 4.70%, a fresh 52-week high, and is now up more than 70 basis points since the Iran war began, according to the Kobeissi Letter, as bond markets keep pricing in an energy shock rather than the rate cuts investors expected earlier this year. The move extends a broader climb across the curve. The 30-Year Treasury yield has now traded above 5.00% for the longest stretch since 2007, spending 27 trading days above that level so far in 2026, or roughly 19% of all sessions this year. Just a few months ago, markets were pricing in three or more Federal Reserve rate cuts for 2026, a bet that has largely unwound as inflation risk from a wider Middle East conflict, including the threat to oil supply through the Strait of Hormuz, keeps upward pressure on long-term borrowing costs. Rising yields on the long end typically raise the discount rate applied to future corporate earnings, which weighs hardest on growth and technology stocks trading on distant profit expectations, while also raising the government's own interest expense on new debt. With both the 10-Year and 30-Year yields near multi-year highs at the same time oil is trading near its own highs, the bond market is effectively pricing the Iran conflict as a persistent inflation risk rather than a short lived spike.
Why it matters · Yields near a 52-week high are not just a bond market story. They raise the discount rate on future profits, hurting expensive growth and AI stocks, raise the government's own borrowing cost, and confirm that the market now sees the Iran war as an inflation risk rather than a one-off shock, which is why the rate-cut bets from earlier this year have mostly disappeared.
Worth asking · Long-term Treasury yields are near multi-year highs at the same time oil is near its own highs, with markets now pricing the Iran war as an ongoing inflation risk rather than a short lived spike. Does that combination make you more worried about a broader risk-off move in stocks, or do you think yields are already close to peaking?
