BitMEX founder Arthur Hayes says Bitcoin could see a strong rally in 2026. His prediction depends on the Federal Reserve taking action to support the Japanese yen.

Hayes shared his view on X after Bloomberg reported the yen reached its strongest level since August. The currency traded around 155.63 per dollar during Asian trading sessions.

The former BitMEX CEO believes the key factor is Fed balance sheet expansion. He argues that if the Fed sells dollars to buy yen, it would inject new liquidity into the financial system.

Hayes told traders to watch the Fed’s weekly H.4.1 report. The “foreign currency denominated assets” line would show whether intervention is happening. Historically, Fed balance sheet growth has matched periods of stronger Bitcoin performance.

Reports indicate the New York Fed conducted dollar-yen rate checks in January. These checks often signal authorities are monitoring currency markets closely. They sometimes come before intervention but don’t confirm action has taken place.

Japanese officials have warned against sharp currency moves this month. The Treasury Department has not announced formal intervention. The Fed’s latest data shows no evidence of the liquidity expansion Hayes describes.

Current Fed Data Shows Different Picture

The most recent H.4.1 releases show foreign currency assets near $19 billion with no increase. The Fed’s total balance sheet sits around $6.58 trillion and continues to shrink.

Balance sheet estimates show a decline of roughly $75 billion per month. Bank reserves also dropped in recent data. This points to ongoing quantitative tightening rather than expansion.

Treasury holdings increased slightly in the latest report. The overall balance sheet did not expand. Analysts say this confirms the Fed is continuing to reduce liquidity.

Hayes believes this could change if yen support becomes official policy. He argues the resulting dollar flow could lift Bitcoin and spread across the wider crypto market.

Market Reaction Remains Cautious

Traders have not fully embraced Hayes’s prediction. Polymarket data shows more users expect Bitcoin to fall toward $80,000 before any rally begins.

Institutional investors are pulling back. Bitcoin ETFs recorded $104 million in net outflows on January 23. This marked the fifth straight day of selling.

Total ETF outflows exceeded $1.4 billion over the past week. The selling pressure comes even as Hayes makes his case for a coming bull run.

The Bank of Japan kept interest rates unchanged last Friday. Markets had expected a possible rate hike. The decision to hold rates steady removed some downside pressure.

Analysts warn that rapid yen appreciation carries risks for Bitcoin. A sharp rise can force investors to unwind yen carry trades. These trades involve borrowing yen to invest in higher-risk assets.

When carry trades unwind, investors sell risk assets to cover positions. This process can weigh on stocks and cryptocurrencies. The effect can happen even if broader liquidity improves later.

Bitcoin currently trades at $89,470. The dollar-yen rate moves between 155 and 158. Markets are waiting for concrete signs of Fed action.

Observers say confirmation would require clear evidence in the H.4.1 report. Foreign currency assets would need to rise without offsetting reductions elsewhere. Until that happens, current conditions reflect liquidity reallocation rather than expansion.

Hayes maintains his view that intervention would be bullish for Bitcoin. Other market participants are watching Fed data releases for proof the policy shift is real.
