A Panicking Japan Considers Shorting Oil To Prop Up The Crashing Yen
With the yen collapse accelerating, and pushing the USDJPY above 160 for the first time since 2024, markets are on edge expecting a BOJ intervention at any moment as this was the price when the BOJ intervened last time.
However, with BOJ interventions having been consistently proven futile with a half life of just weeks if not days, Japan - facing soaring inflation yet desperate not to raise rates as that would crash the stock market - is weighing a controversial (some would say idiotic) new plan to arrest the yen's slide: stepping into oil futures markets.
Reuters was informed by "market sources" that Japan's government is considering intervening in the crude oil futures market as the Middle East crisis drives energy prices up sharply. Under the scheme, Japan would tap its $1.4-trillion foreign exchange reserves and build short positions in the oil futures market by selling futures contracts to push down prices.
By dampening demand for dollars to buy oil, the "brilliant" thinking goes, Tokyo can ease selling pressure on the yen.
The oil futures and currency markets (which in turn are driven by soaring yields) have recently moved in tandem, with the Middle East conflict pushing oil prices higher while lifting safe-haven demand for the dollar.
Details of the proposal remain scant, after Reuters reported on Monday that it was under discussion, but the idea underscores Tokyo's mounting frustration. Policymakers increasingly see speculative surges in energy prices as a major driver of the yen's weakness against the dollar - and a problem monetary easing and verbal intervention no longer seem able to contain.
Of course, anyone with even half a brain - which unfortunately excludes everyone at the BOJ these days - including analysts and even some in the government, are questioning whether such a strategy would have any meaningful impact in arresting the yen's current weakness, which they mostly attribute to dollar strength, rather than speculative yen short-selling.
"The government must be aware that the impact would inevitably be temporary," Shota Ryu, FX strategist at Mitsubishi UFJ Morgan Stanley Securities, said. "They would likely use it mainly to buy time till the Middle East situation improves."
Japanese law allows use of foreign exchange reserves, preserved as a war chest for direct currency-market intervention, to take positions in futures markets if the objective is to stabilise the yen. After all, the BOJ is one of the few central banks that takes pride in directly manipulating the stock market through purchases of ETFs. Might as well start shorting oil too.
The idea is being contemplated within the government, though there is no consensus on its feasibility, said three government sources with knowledge of the deliberations.
"I personally wonder whether it would mean anything if Japan did it on its own," one of the sources said, casting doubt on whether Tokyo can get much bang for its buck without joint action with other countries.
The unconventional step has emerged as policymakers privately worry that conventional yen-buying intervention could prove futile under current circumstances, as any such action could be blunted by a surge in dollar demand that could intensify if the Middle East conflict drags on.
The shift in the government's tactics has been signalled in government officials' recent comments. Instead of warning against speculative trading in the foreign exchange market, Finance Minister Satsuki Katayama on Tuesday blamed speculative moves in crude oil futures markets for swaying the foreign exchange market.
"The Japanese government is determined to take thorough action at all times and on all fronts," she said, signaling the possibility of being more creative in propping up the yen as the currency approached the psychologically important 160 line.
There was no immediate clarity on which international platform Japan may intervene - NYMEX, on which WTI crude oil futures trade, ICE, where Brent trades, or the Dubai futures trade, a benchmark for Asia. Not that Japan has even thought ahead that far.
But no worries, "as with currency intervention, such an operation could be made on any platform," a second source said. Just brilliant.
Any such move would follow Japan's decision to partially release its oil stockpiles, in coordination with the International Energy Agency and on its own, to soften the supply disruptions which started to hit end-users.
But analysts are skeptical whether the move would pay off.
"The government's strategy is likely aimed at dampening near-term volatility more than anything. It's not possible to financially engineer a way out of a physical oil shock," Yuriy Humber, CEO of Tokyo-based consultancy Yuri Group, said. "If officials want intervention to make an impact, it must be synced with an inflow of real barrels of oil, and ideally, it should be an international effort."
On March 5, a senior White House official said that the US was considering potential action involving the oil futures market, but the idea was promptly shot down by Scott Bessent.
Of course, holding large short positions could also potentially cause losses if the market continues to move higher, and could even force a state-wide margin call on Japan especially if oil hits $200 as some speculate, resulting in total fiscal destruction, something never seen before.
Japan burnt through more than $10 billion in foreign reserves per round of intervention in its most recent currency actions in 2024.
Tony Sycamore, market analyst with IG in Sydney, suggested Japan would need to spend at least $10 billion to $20 billion for the effects to be noticeable.
"I don't think it makes sense at all irrespective of whether Japan does it alone or it teams up with other nations," Sycamore said. "The key to all of this is opening the Strait of Hormuz."

Four leading AI models discuss this article
"Japan is attempting to solve a monetary/yield problem through commodity futures manipulation, which will fail and likely cost $10-50B in losses without addressing the 450bp US-Japan rate differential driving yen weakness."
The article conflates three separate problems—yen weakness, oil price volatility, and dollar strength—and proposes a solution that addresses none of them directly. Japan shorting oil futures won't weaken the dollar; it will only create a massive contingent liability if crude rallies. The real driver of USDJPY weakness is the 450bp+ yield gap favoring the US, not oil speculation. The BOJ's actual constraint is political: raising rates crashes the Nikkei and exposes zombie corporates. Oil shorts are theater masking the core problem: Japan needs either US rate cuts (unlikely) or domestic fiscal/structural reform (politically impossible). The $10-20B spend is also trivial relative to daily oil futures volume (~$100B+), making any price impact ephemeral.
If coordinated multilaterally and paired with actual SPR releases, oil futures intervention could suppress energy-driven dollar demand enough to buy time for geopolitical de-escalation or Fed pivot—and the article dismisses this possibility too quickly by focusing on Japan acting alone.
"Japan is attempting to use financial engineering to solve a structural trade deficit and interest rate disparity, which risks catastrophic fiscal losses if oil prices continue to rise."
This proposal is a desperate pivot that signals the Bank of Japan (BOJ) has exhausted its traditional toolkit. Shorting oil futures to support the Yen (JPY) is fundamentally flawed because it ignores the interest rate differential—the primary driver of USD/JPY strength. While Japan holds $1.4 trillion in reserves, entering the highly leveraged commodities market introduces 'state-wide margin call' risks. If Middle East tensions escalate, Japan could face uncapped losses on short positions while the Yen continues to slide due to its status as a net energy importer. This is a move of fiscal theater that likely marks the 'blow-off top' for Yen weakness before a forced, painful rate hike.
If Japan's shorting coincides with a de-escalation in the Middle East, the resulting 'double-whammy' of falling energy costs and reduced dollar demand could trigger a massive short squeeze on Yen speculators, propping up the currency without raising rates.
"Using FX reserves to short oil futures is a high-risk, temporary tactic that misreads the primary driver of yen weakness—interest-rate differentials—and could produce outsized losses without resolving structural FX pressure."
This proposal reads like a politically driven Hail Mary: using FX reserves to short oil futures may have a fleeting psychological impact but is unlikely to fix the structural cause of USD/JPY weakness — the US-Japan yield gap and dollar strength. Operationally it raises thorny questions: which venue, margin rules, mark-to-market risk, legal optics of market manipulation, and coordination with physical oil releases. Large short positions can generate catastrophic losses if the Middle East risk premium stays elevated; meanwhile importers and corporates will keep buying dollars to pay for physical barrels, muting any FX benefit. The move buys time, not a durable solution.
If oil price spikes are currently the dominant driver of dollar demand, a well-sized, coordinated futures short plus strategic SPR releases could temporarily reduce dollar bids and stabilize USD/JPY—especially if allied buyers dampen the counter-movements. Short-term volatility suppression could be politically valuable even if not permanent.
"Oil shorting won't meaningfully prop the yen, as rate differentials dominate and market depth overwhelms Japan's firepower."
This ZeroHedge-sourced rumor of Japan shorting oil futures reeks of desperation but ignores scale: global oil futures turnover exceeds $1T daily, vs Japan's contemplated $10-20B salvo—barely a ripple, as past FX interventions (burning $60B+ in 2024) proved futile within days. Key omission: yen's 30% plunge since 2022 stems from US-Japan yield gap (5% vs 0.25%), not oil imports (~3% of CPI). Execution risks margin calls if Middle East flares push WTI/Brent >$100 (from $75 now), eroding $1.4T reserves further. Signals policy exhaustion, but no G7 buy-in means vaporware.
If Japan syncs with IEA oil releases and G7 partners for a multi-$100B short blitz, it could cap prices effectively, slashing USD oil demand and buying yen time without rate hikes.
"Margin call mechanics on a $20B short position in a $1T/day market could force Japan to exit at a loss before any yen benefit materializes."
Everyone's underweighting execution risk on the margin call scenario. Grok flags it, but nobody quantifies it: if WTI hits $100 (plausible if Iran escalates), Japan's $20B short position loses ~$8-10B in mark-to-market within weeks. That's not theoretical—it forces either capitulation (losing the trade) or doubling down (burning reserves faster). The real tell: no panelist mentioned whether BOJ has legal authority to hold leveraged commodity shorts. That's not theater; that's a structural blocker.
"The proposed intervention creates a massive moral hazard that invites speculative attacks on Japan's remaining reserves."
Claude is right about the legal void, but everyone is missing the 'crowding out' effect. If Japan shorts oil to save the Yen, they signal to every macro hedge fund that the BOJ is the ultimate counterparty. This won't just fail; it will invite a speculative attack on both the Yen and WTI simultaneously. Traders will front-run the BOJ's exit, turning a $20B intervention into a liquidity trap that accelerates the very reserve depletion Grok fears.

"Gemini's crowding out scenario is implausible due to oil futures' immense liquidity relative to BOJ's position."
Gemini's 'crowding out' and speculative attack thesis ignores liquidity reality: oil futures average $1T+ daily turnover dwarfs Japan's $20B position, making BOJ the mouse, not the whale. Hedge funds won't pivot from profitable USDJPY longs (~$200B speculative net shorts on yen per CFTC) to chase a sideshow. Connects Claude's margin math: $10B loss at $100 WTI just accelerates reserve burn without FX upside, per my opener.
