Bonds sell off as oil rises

Government bond markets fell across the United States, Europe and Asia on May 15 as investors absorbed a fresh rise in oil prices and a run of hotter U.S. inflation data. U.S. Treasury yields climbed to their highest levels in about a year, with the longest maturities leading the move. Reuters and Bloomberg both reported that investors were repricing the risk that energy-driven inflation could keep central banks on a tighter path for longer. Bloomberg Television used the same framing in its May 15 program “The Close,” which highlighted a global bond selloff as oil rose. (money.usnews.com) (finance.yahoo.com) The move was broad rather than isolated to one market. Bloomberg reported yields surged from Japan to the United States, while Reuters said investors were assessing the economic costs of the war with Iran and the effect of energy disruptions on inflation. Brent crude rose 4% to above $109 a barrel in one Reuters account, while another Reuters report said oil gained 3% on the day. ### Which bond markets moved the most on May 15? U.S. Treasuries set the pace on May 15. Reuters reported the benchmark 10-year Treasury yield rose 9.3 basis points to 4.552%, after touching 4.558%, the highest since May 2025. (money.usnews.com) The 30-year bond yield rose 8.6 basis points to 5.0992% and reached 5.103%, also the highest since May 2025. The 2-year yield climbed to 4.071% at its session high, the highest since March 2025. Japan and Britain also saw large moves at the long end of their curves. Bloomberg reported Japan’s 30-year government bond yield hit 4% for the first time since that bond was first issued in 1999, while 30-year gilt yields in Britain reached a 28-year high. (finance.yahoo.com) Reuters described the global selloff as one that was pushing investors to brace for “interest-rate pain.” ### Why did oil matter so much to bond traders? Oil prices fed directly into inflation fears. Reuters reported that investors were already rattled by U.S. inflation readings showing the largest annual gain in consumer prices in three years and the biggest increase in producer prices in four years. (money.usnews.com) In that setting, a further rise in crude added to concern that energy costs would keep price pressures elevated. The Middle East conflict was central to that calculation. Reuters said ongoing ship attacks and seizures around the Strait of Hormuz were part of the disruption driving concern, while Bloomberg said the U.S.-China summit failed to produce a breakthrough toward ending the war in Iran. (finance.yahoo.com) Both accounts tied the oil move to a wider repricing of inflation and rate expectations. ### What were investors and strategists saying? Subadra Rajappa, head of research at Societe Generale Americas, told Bloomberg Television that bond yields “feel like they are getting unhinged.” She said the market was “not only testing the Fed” but also putting pressure on Congress as financing costs rise. (money.usnews.com) Seth Hickle, a portfolio manager at Mindset Wealth Management in Indianapolis, told Reuters that “with sticky inflation, higher rates are going to be here for longer.” Kenny Polcari, chief market strategist at Slatestone Wealth Management, told Reuters that equity investors had not been paying enough attention to what the bond market and economic data were signaling.

Reuters said major global stock indexes were down between 1% and 2%, one day after the S&P 500 and Nasdaq had hit new highs. (finance.yahoo.com) Bloomberg also reported that investors were beginning to worry the rise in yields could reverse part of the rally in equities since late March. The next official checkpoint comes this week in Paris. Bloomberg reported that Japan Finance Minister Satsuki Katayama said she and her Group of Seven counterparts would discuss the bond selloff at their meeting, putting sovereign borrowing costs and market volatility on the agenda.
