Brent Crude Tops $100 a Barrel as Middle East Tensions Flare, and the Fed Now Has an Inflation Problem

Brent crude opened at 108.92 dollars a barrel on September 11, after a week that saw prices surge 9.7 percent. The move followed renewed advances by Iran-backed Houthi forces toward the Bab al-Mandeb Strait, a key shipping chokepoint, and a precautionary shutdown of Saudi Arabia’s East-West pipeline after a string of attacks. Iranian state media later said Tehran would meet Gulf states in Oman to discuss the Strait of Hormuz, and the rally paused as oil settled near the 100 dollar mark.

This is the first time Brent has traded above 100 dollars since 2022, and the reason it matters well beyond energy desks is straightforward: fuel costs feed into almost every other price in the economy. The longer oil stays elevated, the more likely that pressure shows up in core inflation figures over the coming months.

Why currency traders are watching an oil chart

Higher inflation risk narrows a central bank’s options. If energy costs keep core prices moving up, the Federal Reserve has less room to cut rates even where growth data looks soft, which is exactly the tension already splitting Wall Street ahead of the September 16 decision. Pricier fuel does not just cost more at the pump; it feeds into the cost of shipping, manufacturing and eventually almost everything on a supermarket shelf, which is why one commodity can move an entire currency market. That dynamic has been pushing both Treasury yields and the dollar higher in recent sessions, and it is a large part of why gold has struggled to hold its own gains even with inflation risk rising.

Supply-side numbers complicate any quick resolution. The International Energy Agency has cut its global demand outlook by 2.5 million barrels a day for 2026, even as the US Energy Information Administration raised its 2027 production forecast to 14.3 million barrels a day. Those figures point to a market that should loosen over time, but geopolitical risk in the Gulf can override that math for as long as tensions stay high.

Trader’s takeaway: as long as Brent holds above 100 dollars, lean toward dollar strength and be cautious on risk-sensitive currencies like the Australian and New Zealand dollars. Keep an eye on headlines out of the Oman talks over the Strait of Hormuz specifically, since a single line of news there can move oil, and currency pairs with it, within minutes.
