NextFin News - The four-day rout in the U.S. Treasury market deepened on Thursday as the escalating conflict between the U.S.-Israel alliance and Iran sent oil prices to their highest levels in nine months, shattering the fragile consensus that inflation had been permanently tamed. In Singapore trading, the benchmark 10-year U.S. Treasury yield climbed as much as five basis points to reach a three-week peak of 4.131%, marking its most aggressive weekly ascent since April 2025. The selloff reflects a sudden, violent repricing of risk as the prospect of a prolonged Middle Eastern war threatens to choke global energy supplies and force the Federal Reserve to abandon its planned easing cycle.
The catalyst for the bond market’s distress is the paralysis of the Strait of Hormuz, a vital artery for global energy through which roughly a fifth of the world’s oil consumption passes. With Iran launching missile barrages at Israel and U.S. forces engaged in the theater, West Texas Intermediate crude surged to $78.09 a barrel on Thursday. For fixed-income investors, the math is increasingly grim: every dollar added to the price of a barrel of oil acts as a regressive tax on the consumer while simultaneously stoking the headline inflation figures that the Federal Reserve uses to calibrate interest rates. Jose Torres, senior economist at Interactive Brokers, warned that unless crude costs tumble in short order, the U.S. consumer price index is poised to return to the upper 2% range, a reversal that would effectively kill the "immaculate disinflation" narrative that fueled the early 2026 rally.
Market expectations for monetary policy are shifting with startling speed. Only a week ago, the CME FedWatch tool indicated a better than 40% chance of a rate cut in June; by Thursday afternoon, those odds had withered to roughly 30%. Traders are now pricing in just over 40 basis points of total easing for the remainder of the year, a far cry from the aggressive cutting cycle anticipated in January. This hawkish pivot is being reinforced by resilient domestic data, including a February services sector report that showed activity hitting a three-and-a-half-year high. The combination of a "hot" economy and a "hot" war is a nightmare scenario for bondholders who had positioned for a cooling labor market and falling yields.
The pain is particularly acute at the short end of the curve, where the two-year Treasury yield rose to 3.566%, up more than 18 basis points on the week. This move suggests that the market is no longer just worried about long-term inflation, but is actively betting that U.S. President Trump’s administration will face a Federal Reserve that is forced to keep rates "higher for longer" to combat the supply-side shock of expensive energy. While U.S. President Trump has historically favored lower interest rates to stimulate growth, the geopolitical reality of the 2026 conflict may leave the central bank with little choice but to maintain a restrictive stance to prevent inflation expectations from becoming unanchored.
The broader economic fallout extends beyond the bond pits. As yields rise, the discount rate applied to future corporate earnings increases, putting immediate pressure on equity valuations, particularly in the technology and growth sectors. The "risk-off" sentiment is palpable, yet it is being met with a "cost-push" inflation reality that prevents bonds from acting as their traditional safe-haven hedge. In this environment, the traditional 60/40 portfolio is finding no place to hide, as both legs of the strategy buckle under the weight of geopolitical instability and the specter of a second wave of inflation. The focus now turns to whether the conflict remains contained or if the disruption to the energy complex becomes a permanent fixture of the 2026 economic landscape.
