Oil prices moved higher at the start of the week as military tensions between the United States and Iran intensified, creating fresh concerns for investors already watching inflation and interest rates closely. Brent crude climbed to around $78 a barrel, noticeably above levels seen before the latest escalation in the Middle East, raising questions about how long energy markets can avoid further disruption.
The renewed rise in oil prices arrives at a sensitive moment for Federal Reserve Chairman Kevin Warsh and policymakers on the Federal Open Market Committee. Higher energy costs can feed into inflation expectations, complicating efforts to steer price growth back toward the central bank’s 2% target while maintaining economic stability.
Strait of Hormuz Remains the Market’s Main Concern
Over the weekend, Washington and Tehran exchanged strikes in a conflict that has expanded beyond earlier expectations. While U.S. President Donald Trump stated that the Strait of Hormuz remains open, Iranian authorities reportedly maintained that the strategic waterway is effectively closed.
The Strait of Hormuz is one of the world’s most important energy shipping routes, carrying a significant share of globally traded crude oil. Any threat to traffic through the passage can quickly affect supply expectations and commodity prices.
The situation has broadened beyond direct exchanges between the two countries. Reports indicated that Iran’s Islamic Revolutionary Guard Corps claimed attacks on U.S. facilities in Bahrain, Kuwait and Jordan. Meanwhile, U.S. Central Command said its latest actions followed an Iranian attack on a commercial vessel operating near the Strait.
Financial markets had been hoping for signs that hostilities might ease. Instead, oil futures suggest traders expect elevated crude prices to persist in the coming months, with contracts implying prices could remain above pre-conflict levels through the end of the year.
Goldman Sachs Warns of Inflation Risks From Higher Crude
Economists are now assessing how sustained energy price increases could influence inflation and monetary policy. Goldman Sachs chief U.S. economist David Mericle said several factors may still help moderate inflation over the coming months, including the possibility of reduced geopolitical tensions, fading tariff effects and what he described as overstated demand linked to artificial intelligence investment.
Even so, the bank cautioned that policymakers have little room for error. According to Goldman Sachs analysis, a renewed jump in oil prices to around $100 per barrel could add roughly three to four basis points to monthly core inflation readings in the near term.
That would come on top of the most recent U.S. core inflation rate of 4.2% reported for May, a figure that remains well above the Federal Reserve’s long-term objective.
Mericle noted that the challenge extends beyond the direct mathematical impact of energy prices. Repeated supply shocks can influence how businesses and consumers think about future inflation, making it more difficult for central bankers to maintain confidence that price pressures will eventually subside.
Energy Security Investments Could Accelerate
The latest market reaction also highlights a broader shift underway in global energy infrastructure. Goldman Sachs commodity analysts argued that disruptions around the Strait of Hormuz may encourage governments and producers to accelerate investment in alternative export routes.
That trend has been developing for several years as Gulf nations seek to reduce dependence on a single maritime chokepoint. According to Goldman Sachs estimates, new pipeline projects could eventually shield nearly half of pre-conflict Persian Gulf export volumes from future Hormuz disruptions by the end of 2027, with the proportion rising further by 2028.
The push for greater energy security mirrors earlier responses to supply shocks, including the disruptions that followed Russia’s invasion of Ukraine. Those events prompted governments and companies to diversify supply chains, expand storage capacity and invest in alternative transportation networks. Similar strategic planning could emerge across the Middle East if current tensions persist.
What Investors Will Be Watching Next
For markets, the next phase of the conflict may matter as much as the current price spike. Investors will closely monitor whether shipping traffic continues through the Strait of Hormuz and whether diplomatic channels show signs of reducing tensions.
For the Federal Reserve, the key question is whether higher oil prices become a temporary shock or evolve into a broader inflation problem. If energy costs stabilize, policymakers may be able to maintain their current stance. If crude prices continue rising, the path toward lower inflation could become considerably more complicated.
