Brent crude oil has surpassed $100 a barrel, reaching this level for the first time in six weeks, driven by heightened tensions and military actions between the U.S. and Iran. U.S. forces destroyed five Iranian tankers, directly impacting oil supply and contributing to the price surge. This escalation in conflict has intensified worries about global oil supply, especially given already low stock levels and reduced exports from the Middle East. The price jump represents a quarter increase since early last month, although it remains below the year's high of $126 reached in April.

The rising oil prices are sparking fears of increased inflationary pressures and higher energy costs for consumers and businesses worldwide. This situation is leading central bankers to closely monitor oil-related metrics, such as the "crack spread"—the difference between the price of finished fuels and crude oil—as an indicator of inflation. Bank of England Governor Andrew Bailey, for instance, has noted increased attention to this spread rather than just headline oil prices.

In response to the volatile geopolitical landscape, oil traders are reportedly becoming more cautious and selective in their long-term investments. According to Morgan Stanley, traders are now concentrating derivatives positions over shorter time horizons and shifting from broad derivatives exposure to more specific instruments. This reflects a more "clinical" approach to risk management amidst the uncertainties posed by ongoing conflicts in Iran and Ukraine, which are clouding the market outlook beyond the immediate future.
