SINGAPORE: Oil prices edged higher on Monday helped by a weak dollar and expected US stimulus measures but gains were capped by rising global coronavirus cases and tensions between the United States and China.

Brent crude rose 32 cents, or 0.7 percent, to $43.66 a barrel, while US West Texas Intermediate (WTI) crude was up to $41.62 a barrel or 33 cents.

The US dollar index reached its lowest since September 2018, hurt by deteriorating US-China relations and domestic economic concerns as coronavirus infections showed no sign of slowing.

“Massive monetary stimulus has bullish implications for oil,” analysts from Raymond James said in a note, adding that oil prices have historically moved upwards with inflation spikes and that the current US money supply increase is unprecedented.

Oil price gains were capped by escalating China-US tensions following the closures of consulates in Houston and Chengdu. Global coronavirus cases, meanwhile, exceeded 16 million.

In Asia, fresh lockdowns were imposed and in Europe, Britain imposed a quarantine on travelers returning from Spain.

Brent is on track for a fourth straight monthly gain in July and WTI is set to rise for a third month. Helping are unprecedented supply cuts from the Organization of the Petroleum Exporting Countries and others including Russia.

Output has also fallen sharply in the United States although the US oil rig count rose last week for the first week since March.

Oil demand has improved from the deep trough of the second quarter, although the recovery path is uneven as resumption of lockdowns in the United States and other parts of the world is capping consumption.

“Oil appears to be caught between opposing forces, crushing price volatility and ranges,” said Jeffrey Halley, senior market analyst for the Asia Pacific at OANDA.
