KEY POINTS
  • Barclays forecasts the price of Brent crude oil will average about $73 a barrel over the next six months, lower than the cost today.
  • More bullish forecasts underestimate the amount of oil Saudi Arabia and its allies can add to the market to offset output and export declines elsewhere, the bank says.
  • The Saudis are likely to heed President Donald Trump's calls to tamp down gasoline prices, including by shipping more oil to the United States to replenish stockpiles.

Oil prices will back away from $80 a barrel over the next six months as Saudi Arabia and its allies add more supplies to the market, Barclays said in a research note on Tuesday.

The bank said the more bullish outlook held by some of its peers "rests on shaky ground," and the market is underestimating the Saudis' ability to manage the market. Saudi Arabia — along with Russia, Kuwait and the United Arab Emirates — has vowed to meet global oil demand as U.S. sanctions cut off Iranian exports later this year and Venezuela's output continues to decline.
