Brent crude rose more than 3 percent on Tuesday, topping $100 a barrel as rising tensions over Iran’s nuclear program sparked oil’s second rally in three sessions after a second-quarter slide.
Revived hopes for more economic stimulus also supported oil prices as the U.S. crude contract settled more than 4 percent higher.
Over the past three sessions, Brent is up 10 percent and U.S. crude nearly 13 percent. Both ended the second quarter with their biggest quarterly losses since 2008.
Iran said it had successfully tested missiles capable of hitting Israel in response to threats of military action against the Islamic Republic over its nuclear ambitions.

“Given that oil prices are low, buying in here is cheap portfolio insurance in case an event occurs,” he added.
Brent prices have recovered from an 18-month low of $88.49 a barrel set on June 22, having retreated from the 2012 peak above $128 hit in early March.
Recent data pointing to slowing global growth has fueled hopes that policymakers in China, Europe and the United States will provide more stimulus to shore up sputtering economies.
Brent rose $3.34 to end at $100.68 a barrel, the highest settlement since May 31. Prices reached $101.58, the loftiest intraday price since front-month Brent reached $101.90 on June 11.
U.S. crude jumped $3.91 to settle at $87.66 a barrel, the highest close since May 30, after reaching $88.04 intraday.

Brent trading volume outpaced turnover for U.S. crude, with volume for both eclipsing their 30-day averages.
In Norway, an oil and gas workers’ strike was another factor supporting oil prices. The strike has slowed crude shipments from the world’s eighth-largest oil exporter, although unions on Tuesday decided against escalating the action for now.
REFOCUS ON IRAN
Iran made its missile-test announcement after Iranian parliamentarians proposed a bill urging it to stop tankers taking oil to supporters of U.S.-led sanctions and a European Union embargo from passing through the Strait of Hormuz.
Iran had previously threatened to shut the strait if the EU went through with its embargo threat. About 17 million barrels a day of oil — almost a fifth of global production — from the top Middle East producers sailed through the strait in 2011.
The EU embargo on Iranian oil took full effect on Sunday after the latest talks between Tehran and major world powers in June failed to move the parties closer to resolving the dispute over Iran’s nuclear program.
