U.S. Secretary of State Marco Rubio stated on Wednesday that the United States remains open to negotiating an end to the Iran crisis, but asserted that Tehran is not acting in good faith regarding diplomatic talks.

The comments come as the escalating conflict continues to disrupt two of the world's most vital oil shipping routes, heightening supply risks for global energy markets.

The diplomatic impasse follows a recent tour of the Gulf by Rubio, which concluded with persistent skepticism from regional allies about the viability of a proposed peace accord.

Iran has formally declared that no meaningful progress was made in recent discussions aimed at establishing an interim peace framework, deepening the standoff between Washington and Tehran.

The disruption to key maritime corridors poses a direct threat to global oil supply chains.

With shipping routes exposed to conflict-related risks, traders are monitoring the potential for further bottlenecks that could tighten supplies and support higher energy prices.
