G7 leaders agreed October 2 on a coordinated set of measures intended to steady energy markets, including the release of 100 million barrels from emergency reserves through the International Energy Agency. The release is scheduled across four months, with diesel supplies front-loaded during the first 20 days.

The statement also calls for refinery maintenance to be coordinated and utilization to rise temporarily where operations allow. G7 members said they would engage other major refining countries about increasing production of refined fuels, particularly diesel, and avoid restrictions on energy exports among member countries.

The IEA is expected to monitor market conditions and report back within 20 days. Leaders left open the possibility of an additional coordinated diesel release if supply conditions require it, making the initial action part of a continuing review rather than a fixed endpoint.

The measures respond to disrupted shipping and elevated price volatility. An emergency-stock release can add supply while infrastructure and navigation remain constrained, but its effect will depend on how quickly barrels reach refiners and consumers and whether commercial flows stabilize.
