Oil prices climbed over 3% on Tuesday as the Iran-Israel conflict raged with no end in sight, though major oil and gas infrastructure and flows have so far been spared from substantial impact. Brent crude futures gained $2.

Investors are regaining some appetite for risk amid rising optimism that the conflict won't spill over into a broader regional crisis.

Oil surged, stocks fell and investors sought safety in the U.S. dollar and government bonds Friday after Israel struck Iranian nuclear and military targets in an attack that raised the risk of war between the two countries and broader instability in the Middle East.
