De-dollarization continues accelerating with news of the Shanghai Petroleum and Natural Gas Exchange (SHPGX), a Chinese-backed exchange for trading energy-related products, settling its first cross-border transaction in digital yuan.

Chinese-based financial news outlet “Yicai” first reported PetroChina International bought one million barrels of crude oil using digital yuan on Thursday. It was the exchange’s first overseas oil settlement in digital yuan. However, the name of the seller was not disclosed.

SHPGX has made several transactions in yuan earlier this year: In March, PetroChina and TotalEnergies completed a yuan-denominated liquefied natural gas transaction on the exchange. According to the exchange, four such LNG transactions have occurred this year.
