US 10-Year Yield Hits 4.79% as WTI Surges Above $87 on Reported Supertanker Strikes

Bond markets and energy prices moved in tandem on September 2 as the US 10-year yield climbed to 4.79% while the 10-year JGB crossed 3% for the first time since 1996. Oil futures rose sharply after maritime reports documented strikes on two supertankers, pushing WTI above the July 27 high. Equity index futures opened lower with S&P 500 contracts down 0.6% and Nasdaq futures off 1.2%, led by semiconductor and technology names.

The move reflects two separate but reinforcing state incentives. Higher yields follow sustained fiscal issuance and divergent central bank signals ahead of the September 18 FOMC meeting, while the oil spike traces to documented maritime incidents in a region where Iranian and US naval postures have remained in direct competition. Primary records from the Energy Information Administration show US crude inventories already tight; any sustained supply disruption raises the probability of further price elevation.

Market participants now focus on the September 3 ISM manufacturing release and JOLTS data. A reading above 50 with prices-paid component exceeding 55 would reinforce the case for unchanged policy rates at the next FOMC meeting. Conversely, any sign of demand contraction would test whether the yield curve steepening persists or reverses.

The two-sided ledger is clear: oil-exporting states gain fiscal space while net importers face higher input costs and potential currency pressure; Treasury holders absorb mark-to-market losses but receive higher future coupons if issuance continues at current volumes.
