Oil prices plunged this week to $65 per barrel as the United States import tariffs and an unexpected OPEC+ supply hike erased $10 per barrel from global benchmarks.

The price appreciated last week when US President Donald Trump imposed tariffs on any country that buys crude from Venezuela.

However, oil prices turned around the corner as of Friday, with Brent falling to $65, the first time since 2021.

According to oilprice.com, the combined effect of Trump’s import tariffs, OPEC+’s inopportune decision to speed up the unwinding of production cuts, and China’s retaliatory actions wiped off $10 per barrel from global oil prices, “with ICE Brent falling below $65 per barrel for the first time since August 2021.”

The US West Texas Intermediate crude futures lost $4.96, or 7.4 per cent to end at $61.99.

“Seeing backwardation barely change compared to the beginning of the week, one could assume that US tariffs are the defining factor for the price change. Nevertheless, this week will not go down well in the history of oil markets,” oilprice.com reports.

China’s retaliatory tariffs on US goods have escalated a trade war that has led investors to price in a higher probability of recession.

China, the world’s top oil importer, announced it will impose additional tariffs of 34 per cent on all US goods from April 10.

According to Reuters, nations around the world have readied retaliation after Trump raised tariffs to their highest in more than a century.

Aside from the tariffs, another factor that further pressured oil prices was the Organisation of the Petroleum Exporting Countries and Allies’ decision to advance plans for output increases.

The group now aims to return 411,000 barrels per day to the market in May, up from the previously planned 135,000 bpd.
