While many foreign firms have been cutting their exposure to PDVSA since the sanctions were imposed, the fact that a lender closely aligned with the Russian state is following suit is significant because the Kremlin has been among Venezuelan President Nicolas Maduro's staunchest supporters.
"PDVSA's accounts are currently frozen. As you'll understand, operations cannot be carried out," the source said. Gazprombank did not reply to a Reuters request for a comment. Reuters reported this month that PDVSA was telling customers of its joint ventures to deposit oil sales proceeds in its Gazprombank accounts, according to sources and an internal document, in a move to try to sideline fresh US sanctions on PDVSA.
