Oil prices edged up about 1% to a two-week high in volatile trade on Tuesday as the market focused more on tight supplies and a weaker dollar than fears an economic slowdown will hit oil demand.
Brent futures finished the day 1% higher at $107.35 a barrel. U.S. West Texas Intermediate (WTI) crude settled 1.6% higher at $104.22 per barrel.
Brent was on track for its highest close since July 4 and WTI for its highest close since July 8.

Last week, U.S. President Joe Biden visited top oil exporter Saudi Arabia, de facto leader of the Organization of the Petroleum Exporting Countries (OPEC), whose crude exports slipped in May to a four-month low at 7.050 million barrels per day (bpd).
Biden hoped to strike a deal on an oil production boost to tame fuel prices, but got no clear assurances from Saudi officials. The kingdom's foreign minister said he saw no shortage of crude in the market, just a lack of refining capacity.
In the United States, expectations for an increase in crude inventories weighed on prices. Analysts polled by Reuters forecast crude inventories rose by 1.4 million barrels last week.
The American Petroleum Institute (API), an industry group, will issue its inventory report at 4:30 p.m. EDT (2030 GMT) on Tuesday. The U.S. Energy Information Administration (EIA) reports at 10:30 a.m. EDT (1430 GMT) on Wednesday.
The U.S. 3:2:1 and gasoline crack spreads - measures of refining profit margins - both fell to their lowest since April.
"Crack spreads continuing plunge of past four weeks to narrowest level since late April ... suggesting weakening product demand," said analysts at Ritterbusch and Associates, a consultancy.
