Energy prices could stay high for months, a year after US-Iran deal

The recent U.S.-Iran peace deal, which aims to restore the flow of oil through the Strait of Hormuz, has triggered a significant shift in global financial markets. While the agreement has brought optimism, particularly among investors who anticipate lower energy costs and reduced inflationary pressures, central banks around the world—led by the U.S. Federal Reserve—are still grappling with the long-term implications of the conflict-driven inflation spike. This has resulted in a renewed focus on tightening monetary policies, despite the apparent easing of geopolitical tensions. The situation highlights how economic stability is increasingly intertwined with political developments, and how even a temporary resolution of hostilities may not immediately reverse the structural shifts in global markets.

Central banks such as the Federal Reserve, the Bank of England, the European Central Bank, and the Bank of Japan have all signaled a willingness to raise interest rates, defying earlier assumptions that inflationary pressures stemming from the Middle East conflict were merely temporary. The U.S. Federal Reserve, in particular, has taken a more hawkish stance, with officials indicating that rate hikes are now on the table rather than being deferred. This marks a departure from previous forecasts, where investors had anticipated two or three rate cuts in 2026. Instead, current market pricing suggests that borrowing costs may rise instead, reflecting growing concerns over persistent inflation and the potential for economic acceleration. The Fed’s shift underscores the broader challenge faced by central banks in balancing the need to control inflation against the risks of slowing economic growth.

The impact of the U.S.-Iran deal extends beyond the immediate relief of energy supply disruptions. Financial markets have reacted positively, with major indices such as the Dow Jones, S&P 500, and Nasdaq recording substantial gains. Investors are betting on the possibility of sustained economic recovery, driven by lower energy costs and improved confidence in global trade. However, these gains have not come without complications. The oil market, though showing signs of stabilization, remains volatile, with Brent crude hovering near $83 per barrel and U.S. crude slightly below $81. Analysts suggest that the market is skeptical about the durability of the peace deal, fearing that the damage inflicted during the conflict may take longer to repair. Additionally, the lack of clarity surrounding the full terms of the agreement has left many uncertainties unresolved, potentially affecting investor sentiment in the long term.

Inflation, which had surged due to the war-related disruptions, remains stubbornly high, particularly in major economies such as the United States and the United Kingdom. These countries struggled to bring inflation back to target levels following the 2021–22 price shocks, and five years of above-target inflation have placed pressure on central banks to maintain credibility. The persistence of inflationary pressures has forced policymakers to reconsider their approach, leading to a more aggressive stance on monetary tightening. For instance, the Bank of England has moved away from its traditional reluctance to act in response to temporary shocks, with policymakers openly discussing the merits of a rate hike. Similarly, the European Central Bank and the Bank of Japan have already initiated rate hikes, signaling a coordinated effort to curb rising prices.

The ripple effects of the Fed’s actions are already being felt globally. The depreciation of the Japanese yen, partly attributed to the hawkish tone of the Fed, has intensified inflationary expectations in Japan and pressured the Bank of Japan to consider further rate hikes. Analysts warn that the weak yen could lead to increased import costs, exacerbating inflationary pressures and prompting the BOJ to adopt a more proactive stance. Meanwhile, the Bank of Norway has also expressed concerns over persistently high inflation, warning that borrowing costs may need to increase later this year. These developments underscore the interconnected nature of global financial systems, where decisions made by one central bank can influence monetary policy across multiple regions.

Looking ahead, the trajectory of global markets will depend heavily on the outcomes of ongoing negotiations between the U.S., Iran, and other regional stakeholders. While the initial success of the peace deal has alleviated some fears, the long-term sustainability of the agreement remains uncertain. If the peace proves durable, the gradual normalization of energy markets could provide a foundation for economic stability. However, if tensions resurface or the agreement fails to address critical issues, the economic consequences could be severe. Investors will continue to monitor developments closely, with the upcoming Federal Reserve meeting serving as a pivotal moment in determining the direction of monetary policy. As the world grapples with the aftermath of prolonged geopolitical instability, the path forward will require careful navigation of both political and economic challenges.
