Oil prices jumped to a four-week high Tuesday, July 14, after renewed U.S.-Iran fighting disrupted tanker traffic near the Strait of Hormuz. Brent crude rose to $86.19 on Tuesday, while West Texas Intermediate advanced to $79.67 a barrel.
President Donald Trump restored restrictions on Iranian shipping as American forces struck targets inside Iran. Iran launched retaliatory attacks, including missiles aimed toward a U.S. base in Jordan. The escalation placed fresh pressure on Federal Reserve Chair Kevin Warsh before the central bank’s July meeting.
Fighting returns near Hormuz
The price surge followed an easing of tensions. Brent settled near $76 on July 10 as traders anticipated smoother shipping through the Gulf.
Those expectations faded after new attacks on commercial vessels and military sites. Tanker movements through the Strait of Hormuz dropped to a two-month low, heightening fears that exporters could struggle to deliver crude and liquefied natural gas.
The United Arab Emirates said Iranian missiles hit two Emirati tankers. One Indian crew member died, and eight others suffered injuries. Iran’s Islamic Revolutionary Guard Corps said the vessels ignored navigation warnings, but independent authorities had not verified that claim.
Trump also announced a renewed blockade of Iranian ports and proposed charging ships for American protection while crossing the strait. The plan’s legal and operational details remained unclear Tuesday.
The fighting weakened a June 17 understanding that had reduced direct attacks. Oil prices fell during that pause as some shipping resumed and traders reduced the conflict premium built into crude contracts.
A critical oil route
The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman. Saudi Arabia, Iraq, Kuwait, the United Arab Emirates, Qatar, Bahrain, and Iran rely on the passage to export energy.
The waterway carried about 20 million barrels of petroleum liquids each day in 2024. That volume represented roughly one-fifth of global petroleum consumption and more than one-quarter of seaborne oil trade.
China, India, Japan, and South Korea receive much of that supply. A serious interruption could force refiners to compete for replacement cargoes from Africa, the Americas, and other producers.
Saudi Arabia and the UAE operate pipelines that bypass the Strait of Hormuz. However, their combined spare capacity cannot replace all normal traffic. New pipelines would require years of construction.
The United States imports less Persian Gulf oil than it did decades ago. American consumers still face global price movements because refiners trade crude against international benchmarks.
Inflation relief faces pressure.
The oil rally arrived as fresh data showed U.S. inflation cooled sharply in June. The Consumer Price Index fell 0.4% during June, marking the largest monthly decline in four years.
Annual inflation slowed to 3.5%, down from 4.2% in May. Core inflation, which excludes food and energy, remained unchanged for the month and rose 2.6% over the previous year.
Lower gasoline prices helped drive the improvement. However, the June figures do not capture the latest jump in crude oil or renewed shipping disruption.
A sustained increase in oil prices could raise gasoline, diesel, and jet fuel prices. Diesel costs can spread through trucking, farming, construction, and retail distribution.
Businesses can absorb short price spikes without immediately changing consumer prices. A prolonged disruption creates greater risk because companies may pass transportation and production costs to customers.
The Federal Reserve will focus on whether energy increases remain temporary. Officials will also watch for signs that higher costs are spreading into services, wages, and long-term inflation expectations.
Warsh faces a divided Fed.
The Federal Open Market Committee maintained rates at 3.5%-3.75% during its June meeting. Policymakers said inflation remained elevated and economic uncertainty stayed high.
The central bank now faces competing risks. Keeping rates high could restrain demand and prevent another inflation surge. Raising them could weaken an economy already absorbing higher fuel and shipping costs.
Cutting rates would lower borrowing costs for households and businesses. It could also leave the Fed more exposed if oil prices push inflation upward again.
Warsh told lawmakers Tuesday that the central bank would not tolerate persistently high inflation. He did not signal whether officials would raise rates, hold them steady, or consider a reduction.
Financial markets initially welcomed the softer June inflation figures. Oil’s renewed rise limited that relief because future price reports may show higher energy costs.
The conflict could also affect consumer spending. Families paying more for fuel often reduce spending on travel, restaurants, clothing, and other optional purchases.
July decision approaches
Oil traders will track tanker traffic, vessel insurance costs, and new attacks near the Strait of Hormuz. A return to stable shipping could remove part of the risk premium and quickly lower crude prices.
Continued disruption could keep Brent elevated and increase pressure on fuel markets. A severe closure would create a larger supply problem than current bypass pipelines could manage.
The Federal Reserve will hold its next policy meeting on July 28 and 29. Until then, officials will monitor fuel prices, inflation expectations, and economic activity as the United States and Iran determine whether the confrontation expands or eases.
