Odaily Planet Daily News: According to three people familiar with the matter, as the United States re-imposes oil sanctions on Venezuela, Venezuela's state-owned oil company PDVSA plans to increase the use of digital currencies in crude oil and fuel exports. The U.S. Treasury Department last week asked PDVSA's customers and suppliers to end transactions by May 31. The move will make it more difficult for Venezuela to increase oil production and exports because companies will have to wait for individual U.S. authorization to do business with Venezuela. Since last year, PDVSA has been slowly accepting USDT, or Tether, in oil sales, whose value is pegged to the U.S. dollar. People familiar with the matter said the restoration of oil sanctions is accelerating the transition, a move to reduce the risk of sales revenue being frozen in foreign bank accounts due to sanctions.
