U.S. Treasury: oil prices could spike in winter

U.S. Treasury Secretary Janet Yellen said Sunday that there is a "risk" that U.S. gas prices could rise again later this year, as fears grow over the possibility that Americans' wallets could be strained by a spike in prices similar to the one seen this summer.

"Well, it's a risk. And it's a risk that we're working on the price cap to try to address," Yellen told CNN when asked if Americans should be worried about gas prices rising again later this year.

"This winter, the European Union will cease, for the most part, buying Russian oil. And, in addition, they will ban the provision of services that enable Russia to ship oil by tanker. And it is possible that that could cause a spike in oil prices," she added.

Yellen continued: "Our price cap proposal is designed to both lower Russian revenues that they use to support their economy and fight this illegal war, while also maintaining Russian oil supplies that will help to hold down global oil prices. So I believe this is something that can be essential, and it's something that we're trying to put in place to avoid a future spike in oil prices.

Earlier this month, finance ministers from the G7 group of countries - the US, Japan, Canada, Germany, France, Italy and the United Kingdom - said they would ban the provision of "services which enable maritime transportation of Russian-origin crude oil and petroleum products globally" above the price cap. That could block insurance cover or finance for oil shipments.

The maximum price would be set by "a broad coalition" of countries, they said in a joint statement. It would take effect alongside the European Union's next batch of sanctions, which include a ban on seaborne imports of Russian oil starting in early December.
