WTI Crude Tops $100 Intraday, a Roughly Four-Month High as Mideast Risk Bites

For Japan, which imports nearly all its energy, oil is the upstream tap for prices—when it rises, freight, power, and food costs seep in, ending up in your travel budget and Japan's inflation data. On the 10th, WTI futures briefly topped $100 a barrel, a roughly four-month high. The driver is Middle East tension, especially U.S.-Iran friction that raises supply fears; oil trades on expectations, so worry alone can lift prices before any actual disruption. Read alongside rising Treasury yields, the chain is clear: higher oil, higher inflation expectations, higher yields. Practical notes: travelers may face higher fuel surcharges and local transport costs during an oil spike; for those tracking Japanese inflation and BOJ hikes, sustained high oil strengthens the case for tightening. Watch whether Middle East tensions escalate and how major producers respond on supply—that determines whether $100 is a brief spike or a new plateau.
