Key Highlights
- BitMEX’s Arthur Hayes says Bitcoin could rise if the Fed expands its balance sheet to stabilize the yen and Japanese government bond markets.
- Stress in Japan’s weakening yen and rising JGB yields may push US authorities to intervene to protect global and US financial stability.
- Bitcoin, trading near $89,000, has historically benefited from increased liquidity during central bank market interventions.
Arthur Hayes, Co-Founder of BitMEX, says Bitcoin could see a strong upside move if the US Federal Reserve intervenes in Japan’s currency and bond markets through balance sheet expansion.
In his latest essay titled “Woomph,” Hayes argues that stress in the Japanese yen and government bond market may eventually force central banks to inject fresh liquidity into the global financial system, a development that has historically supported Bitcoin prices.
Hayes uses the metaphor of a “woomph,” a sound that signals hidden danger in a snowpack, to describe recent market signals coming from Japan. According to him, the sharp weakening of the yen alongside rising yields on long-term Japanese Government Bonds (JGBs) is an unusual and troubling combination.
Normally, a country’s currency strengthens when bond yields rise, reflecting investor confidence. Japan’s divergence, Hayes notes, suggests growing strain beneath the surface.
Why Japan’s bond and currency stress matters
Japan plays a major role in global financial markets. Its investors hold one of the largest foreign investments in the US Treasury bonds, and the nation is highly dependent on imports, in particular, energy.
A weaker yen raises inflation risks for Japan, while higher JGB yields increase borrowing costs for the government and pressure the Bank of Japan’s balance sheet. Hayes argues that the Japanese authorities should not be able to stabilize these markets otherwise the US can intervene to safeguard its interests.
Japanese investors selling US Treasuries in large amounts in a brief period would drive up US yields at a time when Washington is already operating at historically large deficits.
To avoid this instability, Hayes thinks that the Federal Reserve might act indirectly by increasing its balance sheet to boost the prices of the yen and the JGBs.
“The line item to monitor is Foreign Currency Denominated Assets,” Hayes emphasized. “They will not provide a detailed breakdown of exactly which assets it owns. We must infer from JGB price action whether the Fed is present. “
Such intervention, he explains, would involve the New York Fed creating new dollar liquidity, exchanging it for yen, and potentially buying Japanese government bonds. This process would increase the Fed’s balance sheet and inject more dollars into the financial system.
Implications for Bitcoin and crypto markets
Hayes says this type of liquidity expansion would be positive for Bitcoin. Historically, Bitcoin has been doing well when central banks inject more money into the economy because investors seek an alternative to fiat currencies.
While Hayes cautions that the impact may not be immediate, he believes sustained balance sheet growth would eventually lift Bitcoin and other crypto assets in nominal terms.
“Bitcoin will pump alongside a growing Fed balance sheet (gold). It might not happen on your timeframe if you are 100x leveraged trading 1m candles on some shitcoin perp, but Bitcoin and quality shitcoins will mechanically levitate in fiat terms as the quantity of paper money rises,” he said.
Recent market activity supports his broader thesis. In the last year, Bitcoin has been mostly trading flat even with the interest rate cuts in the US indicating that traders are waiting to see more indicators of new liquidity and not policy signals alone.
Current Bitcoin Market Snapshot
The current price of Bitcoin was $88,753.36 and the 24-hour trading volume was $38.17 billion at the time of writing. It is down nearly 10% from the month high, according to CoinMarketCap data.
While Hayes’ analysis remains a theory and not a proven policy outcome, it points to the way in which the traditional financial market changes, especially in Japan, might determine the next significant step of Bitcoin.
