Oil prices increased sharply following air strikes by the United States and Israel on Iran after nuclear talks in Geneva ended without agreement. The attacks, which began Saturday morning, targeted several locations and reportedly resulted in the deaths of Iran’s Supreme Leader, Ali Khamenei, and four other senior officials. Military operations were ongoing as of midday Tuesday, with continued air strikes from the U.S. and Israel, while Iran responded by targeting U.S. interests in the region and striking energy infrastructure and airports across Middle Eastern countries.
Brent Crude oil rose approximately $10 per barrel to nearly $83. Natural gas prices also climbed by 10%, although they remained below levels seen during a cold snap earlier this year. These price movements affected financial markets, as investors reconsidered inflation risks and the Federal Reserve’s possible policy responses.
Bond markets adjusted expectations for interest rate cuts by the Federal Reserve in 2026. Previously anticipating about 2.5 additional cuts this year, market participants now expect closer to 1.9 cuts as of midday Tuesday. Yields on U.S. government bonds increased between 0.08% and 0.12% across maturities from two to thirty years, reflecting concerns that higher energy prices could drive up inflation and reduce the likelihood of near-term rate reductions.
Stock markets declined overall, with regions dependent on imported energy experiencing larger losses. Developed international stocks fell 6.5%, emerging market stocks dropped 7.8%, and the S&P 500 decreased by 1.7% since Friday’s close. In contrast, energy sector stocks gained 2%, while lower-rated corporate bonds declined by 0.4%.
According to data from the International Energy Agency (IEA), Iran supplied between three and four percent of global oil output in 2024; the United States contributed about twenty-two percent over the same period. Despite Iran’s smaller share, transportation risk remains a focus for markets because roughly twenty-one percent of worldwide oil shipments pass through the Strait of Hormuz—a key waterway adjacent to Iran and Oman—raising security concerns and insurance costs that have temporarily reduced oil supply.
Countries reliant on imported energy have been particularly affected by these developments: Japan imports eighty-seven percent of its total energy use, while the European Union imports sixty-four percent according to IEA figures; meanwhile, the United States is a net exporter producing more energy than it consumes.
Rising oil prices can impact consumers directly; analysis from Rice University indicates that every ten-dollar increase per barrel can add about twenty-five cents per gallon at gasoline pumps. Prolonged disruptions in shipping through the Strait of Hormuz could push both energy and gasoline prices higher, potentially acting as a drag on economic growth for companies and households alike while increasing inflationary pressures—thereby further reducing chances for immediate Federal Reserve rate cuts.
Despite current volatility, broader economic conditions remain robust with productivity gains and consumer spending supporting growth forecasts for both economies and corporate earnings in the United States. Wage increases continue to outpace inflation rates domestically, sustaining positive trends in high-frequency consumer spending indicators; recent policy measures such as lower taxes for corporations and individuals alongside earlier Fed rate cuts are also providing support for ongoing economic activity.
Short-term portfolio volatility has risen but remains within normal historical ranges for diversified investors: since Friday’s close (using intraday prices Tuesday), a typical balanced portfolio (sixty percent global stocks/fourty percent core bonds) lost around two percent—a move seen about once monthly since 2008.
“We encourage investors to stay focused on long-term goals during periods of volatility,” stated U.S Bank representatives in their release, “because missing the best 30 days from 1990 to 2025 cut performance roughly in half, reducing annualized S&P 500 returns from 10.8% to 5.3%.”
The bank added: “We continue to emphasize diversification paired with a growth orientation in portfolios, and we are monitoring developments for signs the situation could extend beyond near-term volatility.”
They concluded: “Please reach out to your Wealth Management advisor if you would like additional support or information.”
