European refiners are winding down oil purchases from Iran, closing the door on a fifth of the Opec member's crude exports after the United States imposed sanctions on Tehran, company and trading sources said. The drop in crude purchases from the Islamic republic could complicate efforts by European governments to salvage the Iranian nuclear deal disavowed by US President Donald Trump last month.
Although European governments have not followed Washington by creating new sanctions, banks, insurers and shippers are gradually severing ties with Iran under pressure from the US restrictions, making trade with Tehran complicated and risky.
Trump on May 4 announced his decision to quit the landmark 2015 nuclear deal between Iran and world powers and reimposed sanctions on Tehran. The restrictions on Iran's oil sector take effect after a 180-day "wind-down period" ending on November 4.
Ministers from Germany, France and Britain have urged US officials to shield European companies from the sanctions, but refiners are not taking any chances.
"We cannot defy the United States," said a senior source at Italy's Saras, which operates the 300,000-barrels-per-day (bpd) Sarroch refinery in Sardinia.
Refiners including France's Total, Italy's Eni and Saras, Spain's Repsol and Cepsa as well as Greece's Hellenic Petroleum are preparing to halt purchases of Iranian oil once sanctions bite, the sources said.
These refiners account for most of Europe's purchases of Iranian crude, which represent around a fifth of the country's oil exports.
Iran's crude sales to foreign buyers averaged around 2.5 million bpd in recent months, according to data collected by Reuters and EU statistics office Eurostat. The bulk of the exports go to Asia.
The companies, most of which have long-term contracts with Iran's national oil company, will continue to purchase cargoes until the sanctions take effect, the sources said.
