The Japanese bond market experienced one of the most dramatic repricing events in its recent history.
The ramifications could extend beyond domestic fixed income, and could spill over to riskier global assets, including Bitcoin.

The tightening of liquidity increases the pressure on the yen carry trade
Japanese government bond (JGB) yields have risen sharply since early 2026. The 10-year yield reached about 2.12%, the highest level since 1999, while the 30-year yield reached a record high of nearly 3.5%.
The total increase in yields was about 104 and 120 basis points respectively, a range of adjustments rarely seen in Japan’s long era of ultra-low rates.
The rebuke reflects growing concerns about Japan’s fiscal and monetary path. The government recently approved a record budget of $780 billion for fiscal year 2026. This decision has increased fears of a growing deficit at a time when inflationary pressures are no longer just a theory.
The continued weakness of the yen has raised doubts about whether the Bank of Japan (BoJ) has failed to control inflation.
Kobeissi Lettera analysts noted that the move represents one of the most dramatic repricing operations in the Japanese bond market. They explained that losses will accelerate as investors price in higher deficit spending and political uncertainty.

For decades, the Japanese bond market has been characterized by stability and dominance of the central bank. Now, this assumption is being challenged.
At the same time, there are real signs of shrinking liquidity. Financial commentator Money Ape has warned that liquidity in Japan is “drying up fast”, pointing to a 4.9% decline in money in circulation by 2025, the first decline in 18 years.
For a system built on abundant liquidity, these changes are fundamental.
The low-interest yen trade meltdown poses a slow-burn risk for Bitcoin and cryptocurrencies
This stringency raises concerns for… Global Carry Yen Tradingwhich has been a basis of taking international risks for years. For a long time, investors have borrowed yen at very low interest rates to fund positions in higher-yielding assets in stocks, emerging markets and cryptocurrencies.

As Japanese yields rise and financing conditions tighten, these businesses become more vulnerable to forced liquidation.
RadarHitz reported that rising 30-year bond yields to record levels is putting immediate pressure on commercial carry positions.
The yield on the 30-year Japanese bond is rising to 3.5%, the highest ever, and the pressures are growing on the carry trades in the yen, they wrote in RadarHits. link.
If liquefaction accelerates, risk assets that have benefited from liquidity via yen financing, including Bitcoin, may face renewed volatility.
Some analysts claim that the danger lies in how slowly the tension develops in the markets. Among them is Gastdario, who described the situation as “boiling frog syndrome”, where structural pressures build up gradually enough for investors not to respond until instability becomes inevitable.

In this context, the Japanese financial system that forms the basis of the global transport trade in the yen in real time is weakening, although the crisis has not crystallized.
However, the image does not appear to be one-dimensional. Despite the increase in nominal interest rates, real interest rates in Japan remain negative, a factor that continues to support liquidity and risk.
This dynamic helps explain why Japanese stocks remain near all-time highs and why global capital continues to flow through Japanese markets, Capital Fellows noted. link.
This means there is a huge amount of liquidity in its market, Capital Fellows analysts wrote, asking: Do you think the Fed is lax? It’s nothing compared to the Bank of Japan. link.
This paradox, where the signs of tightening coincide with persistent negative real interest rates, complicates future prospects. The risk lies less in an immediate shock and more in the possibility that a prolonged liquidation of carry trades could quietly wipe out a major source of global liquidity.
Japanese yields through early January 2026 have witnessed continued volatility and instability. It could be fatal for both Bitcoin and the Japanese economic landscape if the Bank of Japan can achieve a soft landing or if bond market jitters lead to broader financial turmoil in the coming months.
