Brent crude oil prices surged by more than 4% following fresh attacks targeting US troops and Saudi energy infrastructure. These developments have cast doubt on the likelihood of a US–Iran agreement, according to FX Street.

ING analysts Warren Patterson and Ewa Manthey highlighted that Brent's rebound came after recent declines, driven by heightened geopolitical tensions undermining diplomatic progress between the US and Iran.

For Japanese investors, this rise in Brent oil prices could impact energy-related equities and influence FX markets, particularly the yen, given Japan's reliance on imported energy resources.
