Brent crude surged above $107 a barrel Thursday, turning the latest Middle East supply shock into a much broader problem for inflation, interest rates and global markets.
The international benchmark settled at $107.63, up about 6.3%, after briefly moving above $108. Brent then extended the rally to roughly $109.62 on Sept. 11 before profit-taking pulled prices back toward $104.
The move was driven by escalating disruption around the Strait of Hormuz and the wider U.S.-Iran conflict, which has restricted Gulf crude flows and increased fears that global supply could tighten further.
We had already flagged the $120 oil risk when Brent first broke $100. The jump through $107 shows that the geopolitical premium is now accelerating rather than fading.
$107 Oil Is Becoming an Inflation Problem
The timing is particularly difficult for central banks.
U.S. producer inflation accelerated to 5.4% year over year in August, up from 4.8%, while energy prices at the producer level jumped 4.2%.
Our latest PPI analysis showed how the inflation surprise immediately pushed markets toward a more hawkish Federal Reserve outlook.
Oil above $107 adds another layer of pressure.
Higher crude prices feed into gasoline, freight, manufacturing and airline costs, meaning the latest energy shock could complicate the inflation picture even if core price pressures begin to cool.
The concern is already visible in rates. The U.S. 10-year Treasury yield climbed to around 4.95%, while the 30-year yield reached 5.36%, its highest level since 2004.
Wall Street Feels the Oil Shock
Stocks also struggled under the combination of expensive energy and higher yields.
The S&P 500 fell 0.6%, the Dow dropped 316 points, and the Nasdaq lost about 0.7% on Sept. 10 as Brent surged. The S&P 500 recorded its fourth straight decline.
That extends the pressure already visible when $100 oil hit stocks.
Markets are increasingly treating crude not just as a commodity story, but as a monetary-policy risk.
Fed-funds futures pushed the probability of another rate hike to roughly 70% or more after the PPI release and oil spike, while investors turned their attention to CPI for confirmation.
Brent has pulled back from its latest high, but that does not erase the bigger move.
The benchmark was below $100 only days ago. Now the market has already tested almost $110, while our recent oil rally analysis had identified the $102–$104 area as an important resistance zone.
