Oil prices move back above $100 a barrel as fresh US strikes on Iran dampen hopes for a Middle East breakthrough and add uncertainty to markets. Multiple outlets report that the renewed fighting follows attempts by the US and Iran to reach an agreement aimed at ending the wider conflict and reopening key shipping routes. While a fragile ceasefire was referenced as starting around April 8, optimism about further progress appears to have weakened after the US carries out strikes described as targeting missile launch sites and vessels.

As a result, energy markets react to increased risk in the region, with Brent crude pushed through the $100 level. Traders also factor in the possibility that negotiations are stalled, with some commentary from experts suggesting talks are stuck in an extended cycle and that the energy market may be entering a phase where the impact is difficult to reverse. Separately, one outlet notes that a rally in US stocks stalls near record highs as investors weigh the renewed escalation.
