Japan plans to release crude oil from reserves to stabilize fuel prices amid Middle East tensions and supply disruptions.

Japan is poised to initiate the release of crude oil from its strategic reserves, starting next Monday. This move aims to mitigate potential increases in gasoline and petroleum prices, which have been influenced by ongoing conflicts in the Middle East and interruptions in oil shipments from the Persian Gulf. The action, as announced by Prime Minister Sanae Takaichi, signifies a historic moment as it will be the first instance the country has accessed its oil reserves without the prior coordination of the International Energy Agency since it began stockpiling in 1978.

This release will begin with 15 days worth of crude oil held by private-sector entities, followed by an additional month’s supply drawn from government reserves. Japan's proactive stance reflects the country’s significant reliance on energy imports from the Persian Gulf region. Takaichi highlighted that current geopolitical tensions have effectively restricted commercial traffic through the strategically vital Strait of Hormuz. This strait is crucial, given that over 90% of Japan's crude oil imports come from Persian Gulf nations.

The prime minister expressed concerns regarding the imminent decline in shipments, anticipating drastic reductions by late March. Such a decrease could lead to severe shortages of gasoline and refined products. As a result, retail gasoline prices have already begun to rise, with recent data indicating that the national average has climbed to approximately 162 yen, which is equivalent to $1.02 per liter, a notable increase from mid-January figures. Projections suggest that prices may surge beyond 200 yen, prompting government intervention to limit costs to around 170 yen, aiming to soften the blow on consumers.

As of December, Japan held around 470 million barrels in petroleum reserves, sufficient to maintain 254 days of domestic consumption. The government's strategy includes adapting and reviewing support measures to ensure public relief continues, even amid prolonged disruptions. Investors should monitor this situation closely, as the developments not only impact Japan's energy landscape but may have wider implications for oil markets globally.
