Markets Respond to Oil and Middle East Tensions

The increasing likelihood of a rate hike is attributed not only to persistent inflation. According to Reuters, several major brokerage firms have begun to view the Fed's July decision as having a less predictable outcome than usual.

BofA Global Research has linked the shift in expectations to rising oil prices. While most brokers, including Deutsche Bank, still anticipated the rate to remain unchanged, they acknowledged a higher risk of an increase amid escalating tensions in the Persian Gulf and limited signals from Fed Chair Kevin Warsh.

Last week, Brent crude briefly surpassed $100 per barrel for the first time since May 26. On July 23, the September futures contract closed at $100.69, according to S&P Global. However, by July 27, oil had retreated from its peak, falling 9% to $87.84 per barrel.

Conversely, data from June provided arguments for a pause in rate hikes. The U.S. Bureau of Labor Statistics reported that the Consumer Price Index fell by 0.4% month-over-month last month, while year-over-year inflation slowed to 3.5% from 4.2% in May.

Additionally, analysts at Grayscale previously indicated a potential bottom for Bitcoin could be influenced by the Fed's future policy decisions.
