Bitcoin merchants are as soon as once more anchoring to FX, after intervention rumors round USD/JPY revived a well-recognized tug-of-war: short-term shock danger from a strengthening yen versus the longer-horizon bid that usually follows a softer greenback and simpler world liquidity.
The spark over the weekend was a viral X thread (2.9 million views) from Bull Principle (@BullTheoryio), which framed reported “price checks” by the Federal Reserve Financial institution of New York as a prelude to coordinated motion. “The New York Fed has already completed price checks, which is the precise step taken earlier than actual forex intervention,” the account wrote. “Which means the US is making ready to promote {dollars} and purchase yen. That is uncommon. And traditionally, when this occurs, world markets surge.”
Bitcoin In The Crosshairs
Bull Principle pointed to the macro backdrop in Japan, years of yen weak point, Japanese bond yields at multi-decade highs, and a still-hawkish Financial institution of Japan, because the stress cooker forcing officers towards extra aggressive signaling. Within the thread’s telling, the important thing variable is coordination: Japan appearing alone “doesn’t work,” whereas joint US-Japan motion “does,” citing 1998 and the Plaza Accord period as historic reference factors.
A Bloomberg report cited by the account described the yen’s sharp leap on hypothesis that Japanese authorities could possibly be making ready intervention to arrest the forex’s slide, after merchants reported the New York Fed had performed price checks with main banks.

The struggle within the replies was much less about whether or not markets moved and extra about what a “price examine” really indicators.
Daniel Kostecki (@Dan_Kostecki) dismissed the viral framing outright, arguing the mechanism is usually misinterpret. “The Japanese requested the NY Fed to behave as their agent within the American market,” Kostecki wrote. “NY Fed workers then began calling banks in New York to carry out the ‘price examine’—strictly on the Japanese’s request. If officers from Tokyo had referred to as New York banks, merchants might need ignored it as a ‘native Japanese downside.’ However when the Fed calls, banks deal with it as a sign {that a} joint intervention (USA + Japan) is likely to be coming.”
That distinction issues for crypto as a result of the thread’s “bull case” leans closely on the concept promoting {dollars} to purchase yen mechanically weakens the greenback and expands liquidity, situations many macro-focused crypto merchants affiliate with risk-asset upside.
Ted (@TedPillows) echoed the liquidity-first interpretation whereas flagging the trail dependency. “The Fed is making ready for a attainable yen intervention,” he wrote, earlier than laying out the causal chain: {dollars} offered, yen purchased, greenback weaker, liquidity larger, danger belongings helped, then warning that “a strengthening yen might first trigger an identical crash like in August 2024.” After that, he added, markets might stabilize and rally.
Michael A. Gayed (@leadlagreport), Portfolio Supervisor of The Free Markets ETF, supplied a distinct rationale for why Washington would care, suggesting the Fed is appearing to stop a situation the place Japan would want to promote US Treasuries to lift {dollars} to intervene—“It’s not that Japan will panic. It’s the Fed that can panic,” he wrote.
Bull Principle’s most concrete crypto declare was that the setup comprises each a near-term lure and a medium-term tailwind. The account argued there are “tons of of billions of {dollars} tied into the yen carry commerce,” which means abrupt yen power can drive deleveraging within the very belongings, shares and crypto, funded with low-cost yen borrowing.
For example, the account pointed to August 2024, claiming a small BoJ price hike pushed the yen larger and “Bitcoin crashed from $64K to $49K in six days,” with crypto shedding “$600B in worth.” Bull Principle framed that episode because the template for the “catch” in 2026: yen power could be poisonous within the first act, even when sustained greenback weak point finally improves the liquidity backdrop for Bitcoin.
LondonCryptoClub (@LDNCryptoClub) leaned into that lagged-liquidity framing, arguing {that a} weaker greenback tends to filter into danger belongings with a delay, whereas additionally introducing a further US liquidity variable. “Continued and accelerated breakdown of the greenback shall be good for Bitcoin and broad danger over the subsequent few months,” the account wrote, including that the greenback “tends to behave with a 3 months lag” exterior of “knee jerk reactions.” It additionally warned {that a} potential US authorities shutdown and subsequent Treasury Common Account rebuild might offset a number of the optimistic liquidity impulse.
At press time, Bitcoin traded at $87,926.
