The average price for a gallon (3.78 litres) of petrol topped $4.00, up from $3.87 just a week ago, according to the American Automobile Association (AAA), which tracks daily petrol prices. It marks the second successive week of increases.The rise comes despite claims that petrol prices are beginning to fall after a report last week showed consumer inflation declined by 0.4 percent on a monthly basis. That was driven by a 9.5 percent drop in petrol prices, according to the Department of Labor’s Bureau of Labor Statistics Consumer Price Index (CPI), released last week. The inflation data reflects a short-lived reprieve in tensions between the US and Iran before fighting intensified again.Between July 17 and 19, only 30 vessels travelled through the Strait of Hormuz, according to Kpler data. LSEG data shows traffic was even more limited over the weekend, with only eight ships transiting the waterway on Saturday and four on Sunday.The tensions are continuing to affect shipping companies. Greece’s Dynacom Tankers said two projectiles struck two of its ships while sailing through the waterway near the Omani coast. The company did not identify who fired the projectiles.“Higher energy prices remain in focus as a re-escalation in the Middle East tensions adds to concerns that last week’s cooler-than-expected inflationary data may not be enough to deter the Fed from raising interest rates later this year,” David Meger, director of metals trading at High Ridge Futures, told the Reuters news agency.US markets were mixed amid the escalating geopolitical tensions, but also as the US chip sector rallied after China’s Alibaba previewed its latest artificial intelligence model, following Apple unveiling new AI developments for its Siri assistant.The tech-heavy Nasdaq was up 0.6 percent, while the S&P 500 gained 0.2 percent in midday trading. The Dow Jones Industrial Average was down 0.25 percent since opening on Monday.Gold, which is typically considered a safe investment during periods of economic uncertainty, slipped slightly on Monday, despite the heightened tensions. Spot gold was down 0.1 percent to $4,011.96 per ounce in midday trading.Treasury yields rose 0.5 percent, while the US dollar gained 0.1 percent.
