As a reminder, Japan is one of the most heavily impacted nations by the US-Iran conflict. That as it is unable to secure oil supply from the Middle East amid the de facto closure of the Strait of Hormuz. And for a country ever so reliant on energy imports, it's a massive blow to the economy.Japan prime minister Takaichi and IEA chief Birol held talks today and it is being reported that she has called for an additional coordinated release of oil stockpile.This will add to the already roughly 80 million barrels that Japan has released in the past two weeks. For added context: Japan says to release about one-month supply of crude oil reserves nextAs for the initial total release from IEA coordinated nations, it is believed to be around 400 million barrels. That's the most in history and even dwarfs the action taken during the Russia-Ukraine conflict back in 2022. So, that really puts things into perspective here.Circling back to Japan, they are one to have a massive buffer of around 254 days' worth of oil in its reserve capacity heading into this crisis. So, they still have much room to work with but it remains to be seen if other nations will have a similar appetite or not considering that they are less impacted than Japan is by the war.It would be a bit odd if the next one were to be that Japan carries out on its own. However, desperate times call for desperate measures. And I reckon not too many countries would be opposed to that, definitely not the US at least.
