Oil prices held near a one-week high on Wednesday on worries about supply disruptions in Russia and the U.S., while the market awaited clarity on sanctions as Washington tries to broker a deal to end the war in Ukraine. Brent futures rose 20 cents, or 0.3%, to settle at $76.04 a barrel, while U.S. West Texas Intermediate (WTI) crude rose 40 cents, or 0.6%, to settle at $72.25. "The market is trying to make up its mind on three bullish drivers: Russia, Iran and OPEC," said BNP Paribas commodities strategist Aldo Spanjer.
