Argentine assets ended the week under pressure, pulled lower by international volatility linked to the Middle East war, in a session marked by falling stocks and bonds, a higher country risk index and renewed oil-driven pressure on inflation and financial expectations. Brent crude settled at $103.14 a barrel, while Wall Street extended its weekly losses amid concern over global energy supply.

The United States has temporarily authorized the sale of Russian oil and petroleum products already loaded on tankers, in a limited easing of sanctions adopted as global energy prices rise because of the Middle East war. The measure was announced by the Treasury Department and will remain in force until April 11.

Rising fuel prices have added new pressure to Argentina’s March inflation outlook, in a month already burdened by the start of the school year, utility adjustments and seasonal pressure on food prices. In the local market, gasoline prices have risen by roughly 7% to 8% so far in March, increasing the risk that monthly inflation could move back toward the 3% range.

U.S. President Donald Trump has authorized the release of 172 million barrels of crude from the Strategic Petroleum Reserve as part of a coordinated action with the International Energy Agency, in a bid to contain rising fuel prices after market disruption caused by the war with Iran. The Department of Energy said deliveries will begin next week and will take about 120 days to complete.

The U.S. government has formally recognized Delcy Rodríguez before a federal court in New York as the Venezuelan authority empowered to act on behalf of the state, giving legal effect to the diplomatic shift toward Caracas announced last week. The move appears in a “statement of interest” filed on March 10 in response to a court order on who legally represents Venezuela in ongoing litigation in U.S. courts.

Venezuela this week took another step toward opening its extractive sector to foreign capital, while the United States authorized limited transactions involving Venezuelan gold. The National Assembly approved on first reading a mining reform pushed by Delcy Rodríguez’s interim government, as Washington issued a license allowing dealings with Minerven, Venezuela’s state gold company, just days after the two countries restored diplomatic and consular relations.

British finance minister Rachel Reeves said on Monday that the United Kingdom was ready to support a coordinated release of international oil reserves if the Middle East crisis keeps pushing up energy prices, though no formal G7 decision has yet been taken. Reeves made the statement after joining a virtual meeting of G7 finance ministers, as oil prices remained elevated because of disruption to shipping through the Strait of Hormuz. Reuters reported that the option under discussion is a joint emergency stock release under the International Energy Agency framework.

Oil prices climbed above US$100 a barrel on Sunday in futures trading, reaching their highest levels since 2022 as the war in the Middle East, the effective closure of the Strait of Hormuz and fresh production cuts among Gulf producers tightened supply expectations. Reuters reported Brent rose as high as US$111.04 a barrel while West Texas Intermediate (WTI) touched US$111.24 in early trading. AP later put Brent at US$107.97 and WTI at US$106.22, both more than 16% above the previous close.

Oil became this week’s clearest barometer of the Middle East crisis, with Brent hovering near US$90 a barrel and WTI around US$87.5, putting both contracts on track for their biggest weekly advance since 2020. The same factor sits behind the surge: the de facto blockage of the Strait of Hormuz, through which roughly one-fifth of the world’s oil normally passes.

Iran’s Revolutionary Guards said on Thursday that their naval force struck a US oil tanker in the northern Gulf and that the vessel “is on fire,” raising fresh concerns about maritime security tied to the regional conflict and the safety of the Strait of Hormuz—one of the world’s most sensitive energy choke points.
