Oil prices steadied on Tuesday as investors bet tight supply and rising vaccination rates will help offset any impact on demand from surging COVID-19 cases worldwide.

Brent crude futures rose 1 cent to $74.51 a barrel by 0819 GMT. U.S. West Texas Intermediate (WTI) crude futures fell 8 cents, or 0.1%, to $71.83 a barrel.

Benchmark prices held their ground even after the United States issued travel warnings to Spain and Portugal due to rising COVID-19 cases. A White House official told Reuters wider travel curbs would not be lifted due to the highly infectious Delta variant and rising domestic infections.

"With oil demand growth likely outpacing supply growth in the near term, we expect oil tightness over the summer, which should boost oil prices," analysts at UBS said in a research note.

In one encouraging sign for fuel demand, Britain reported its lowest daily total of new COVID-19 cases since July 4 on Monday, suggesting a recent surge in infections has passed its peak.

Olympic host city Tokyo, however, is on track to report a record number of coronavirus cases on Tuesday even as athletes continued to compete across the city in the fourth day of the Games.

Analysts tracking mobility data remain confident about fuel demand, counting on vaccinations to guard against strict new lockdowns.

Global oil markets are expected to remain in deficit despite a decision by the Organization of the Petroleum Exporting Countries (OPEC) and its allies, collectively known as OPEC+, to raise production through the rest of the year.

"Robust road traffic data across most major regions suggests rising infections are having minimal impact," ANZ Research analysts said.

Investors are awaiting inventory data from the American Petroleum Institute industry group on Tuesday and the U.S. Energy Information Administration on Wednesday for further evidence that demand is holding up.

Five analysts polled by Reuters estimated, on average, that U.S. crude stocks fell by about 3.4 million barrels and gasoline stocks fell by 400,000 barrels in the week to July 23.
