Bitcoin could see significant upside if the United States Federal Reserve steps in to stabilise Japan’s currency and bond markets, according to Arthur Hayes, co-founder of crypto exchange BitMEX. Hayes believes that mounting stress in Japan’s financial system may ultimately trigger fresh liquidity injections from central banks—a development that has historically favoured Bitcoin and other scarce assets.
In a recent essay titled Woomph, Hayes draws attention to unusual signals emerging from Japan, particularly the combination of a weakening yen and rising yields on long-term Japanese Government Bonds. Under normal circumstances, higher bond yields tend to support a country’s currency by attracting capital flows. Japan’s divergence from this pattern, Hayes argues, suggests that deeper structural pressure is building beneath the surface of the market.
Japan’s importance to the global financial system makes this situation especially sensitive. The country is one of the largest foreign holders of US Treasury securities and relies heavily on imports, particularly energy. A falling yen increases domestic inflation risks, while higher government bond yields raise borrowing costs and place further strain on the Bank of Japan’s balance sheet. Hayes warns that sustained instability could force Japanese investors to reduce their holdings of US Treasuries, potentially pushing US yields higher at a time when Washington is already running historically large fiscal deficits.
To prevent such spillover effects, Hayes suggests the Federal Reserve may be compelled to act indirectly. Rather than announcing a formal intervention, the Fed could expand its balance sheet by creating new dollar liquidity, exchanging it for yen, and potentially purchasing Japanese government bonds. According to Hayes, the key signal to watch would be changes in the Fed’s holdings of foreign currency-denominated assets, even if the specific details are not publicly disclosed. Any improvement in yen strength or JGB prices could hint at behind-the-scenes involvement.
Such an intervention, Hayes argues, would be constructive for Bitcoin. He notes that Bitcoin has typically benefited during periods when central banks expand liquidity, as a rising money supply weakens fiat currencies in real terms and pushes investors toward alternative stores of value. While he cautions that price reactions are rarely immediate, sustained balance-sheet growth has historically lifted Bitcoin over time.
Hayes also points out that Bitcoin’s recent price behaviour supports his thesis. Despite interest rate cuts in the United States, Bitcoin has largely traded sideways, suggesting that markets are waiting for tangible liquidity expansion rather than policy signals alone. In his view, once balance sheets begin to grow meaningfully, Bitcoin and select crypto assets are likely to rise in nominal terms as the supply of fiat money increases.
At the time of writing, Bitcoin was trading around $88,700, with daily trading volume exceeding $38 billion. Although the asset remains below its recent monthly high, Hayes believes developments in traditional financial markets—particularly in Japan—could play a decisive role in shaping Bitcoin’s next major move.
