Oil fell by more than $1 a barrel on Monday to settle at over four-year lows as an OPEC+ decision to expedite its output hikes stoked fears about rising global supply at a time when the demand outlook is uncertain.

When US President Donald Trump was inaugurated to his second term as president on Jan. 20, oil prices were close to the highs of the summer before. By early May, they had plunged by nearly a quarter.

Oil prices may have no relief from further downside in the second half of 2025 with increased supply from the OPEC+ flooding the market.
