Oil prices rose Tuesday after fresh fighting overnight between Israel and Iran diminished hopes that an end to the Middle East war, now in its fourth week, might be imminent.

Brent crude, the global oil benchmark, climbed 1.6% to $101.5 a barrel. WTI, the US benchmark, rose 2.7% to $90.5 a barrel.

Brent had reached more than $114 a barrel at one point Monday before plunging to settle at $99.94, after Trump hailed “very good and productive conversations” with Iran about ending the war.
