Japan’s heavy reliance on imported oil means swings in crude prices feed quickly into its currency and trade balance. The government has hinted that it might step into the oil market in an indirect bid to support the weakening yen, as the war in the Middle East drives up energy costs and threatens the global economy.Trading oil futures to prop up the currency would be a novel approach for Japan and mark the latest effort to mix up its intervention approach to keep speculators guessing. National governments rarely step into energy derivatives markets directly, but Japan’s Finance Minister Satsuki Katayama has expressed concern that speculative trading in oil futures is affecting the foreign exchange market. She said the government stands ready to take “all possible measures, on all fronts.” How are oil prices affecting the yen?Almost all of Japan’s oil consumption is met by overseas imports, and more than 90% of these shipments usually come from the Middle East. The disruption to supply from the Arabian Gulf and increase in benchmark crude prices since late February has driven up the cost of fuel, electricity and food. The risk of a hit to Japan’s economy has already triggered the government to begin releasing 80mn barrels of oil from its national reserves.When energy costs rise, the country needs more dollars to pay for imports, putting downward pressure on the yen and adding to inflation. In the shorter term, speculators can bet on the direction of oil prices and the yen, amplifying volatility. If Japan can cool crude prices, this might ease the pressure on the currency by shaking off some of the speculators. The yen has weakened sharply against the dollar since the start of the Iran conflict.Proponents of government intervention argue that the sheer size of the so-called paper oil market — futures and derivatives trading, which far exceeds physical supply — could make such action effective, even if the impact is indirect. How would intervention in the oil market work?The government could enter the market in many ways. The challenge is finding an approach that maximizes the impact while minimizing the potential cost. One option is to short oil — selling futures contracts in an effort to push current benchmark prices lower — and covering those positions in small amounts over time. Position limits could cap the number of trades in a single contract month, avoiding concentration by spreading the intervention across the futures curve.Any trades would likely be executed through financial institutions, as with standard intervention in foreign exchange markets. The Finance Ministry has contacted major banks in Tokyo with oil trading operations to gather views on intervening in crude oil futures, according to people familiar with the matter.It’s unclear how big any oil market intervention would be, though it would likely be far smaller than the government’s currency interventions, given the experimental nature of the trade and the scale of the dollar-yen market. Japan spent ¥5.9tn ($37bn) on currency intervention in a single operation in April 2024, helping move the exchange rate by more than ¥5 — its largest-ever effort to support the yen. Risking a similar amount on an untested approach seems unlikely.It also remains to be seen at what point Japan would potentially step in. Unless oil prices rise significantly beyond current levels, the incentive to intervene may remain limited. The yen didn’t breach ¥160 per dollar — the rough threshold for Japan’s most recent currency market interventions in 2024 — even when crude approached $120 a barrel in March. Have other countries intervened in the oil trading market?Few countries have ventured into oil trading for macroeconomic purposes.Mexico runs a sovereign oil hedge — the so-called hacienda hedge — which uses derivatives to protect government revenue in the event of falling prices, rather than to influence markets. Malaysia’s state-owned Petroliam Nasional Bhd also known as Petronas, also uses financial hedges, including oil options, to cushion its revenue from crude price volatility.Influencing oil prices — and by extension a currency — would be far more complex.The US considered trading in the oil futures market as one way to contain rising energy prices amid the Iran war. But the Trump administration appears to have ruled out this option. Treasury Secretary Scott Bessent said in mid-March “we’re absolutely not doing that.” What are the risks for Japan?Sometimes just talk of intervention can itself be a tool to prop up the yen. Authorities may be hoping to influence speculative traders through verbal warnings, contacting dealers, and by floating new ideas.If the government were to actually intervene in oil markets, it would be doing so at a time of high volatility driven by the conflict in the Middle East. Shorting oil risks steep losses if crude prices rise and may not have a meaningful impact on the yen, which could damage the government’s credibility. Any trading losses would compound the pain the economy feels from rising import costs.Some are skeptical that Japan will step into the market. Junya Tanase, chief Japan currency strategist at JPMorgan Chase & Co, said that the likelihood of an oil futures intervention is “extremely low, at least in the near term.”
