Oil prices edged higher on Wednesday, finding some respite after plummeting in the last two sessions, as investors assessed the stability of a ceasefire between Iran and Israel.

Oil prices fell sharply Tuesday, returning to levels last seen before the Iran-Israel conflict, as investors cheered news of a ceasefire, albeit fragile, between the two countries.

The fear throughout the Israel-Iran conflict is that it could squeeze the world’s supply of oil, which would pump up gas prices and hurt the global economy.
