Oil prices gave up nearly all of early Friday’s gains after an Iranian official told Reuters that there hadn’t been a missile attack against Iran.

Oil surged by as much as $3 per barrel in Asian trade early on Friday after a U.S. official told ABC News today that Israel launched missile strikes against Iran in the early morning hours today. After briefly spiking to above $90 per barrel early on Friday in Asian trade, Brent fell back to $87.10 per barrel in the morning in Europe.

The news was later confirmed by Iranian media, which said the country’s air defense system took down three drones over the city of Isfahan, according to Al Jazeera. Flights to three cities including Tehran and Isfahan were suspended, Iranian media also reported.

Israel’s retaliation for Iran’s missile strikes last week was seen by most as a guarantee of escalation of the Middle East conflict since Iran had warned Tel Aviv that if it retaliates, so will Tehran in its turn and that retaliation would be on a greater scale than the missile strikes from last week. These developments were naturally seen as strongly bullish for oil prices.
