- Japan’s 40-year bond yield rose to 3.774% on Thursday.
- The five-year CDS spread hit 21.73 basis points on 20 November.
- GDP contracted in Q3 2025 and inflation reached 3% in October.
Japan’s new stimulus package triggered sharp reactions across global markets: the yen plunged to its weakest level versus the US dollar since January 2025 and long-term bond yields climbed to record levels.
The Cabinet approved a 21.3 trillion yen package on Friday—the largest since the COVID-19 period—and the announcement immediately shifted expectations in currency, bond, and crypto markets.
The scale of fiscal support and the strains on Japan’s finances are prompting investors to reassess how they price global risk, especially as liquidity dynamics evolve.
Economic reset
The package focuses on easing price pressures, supporting growth, and strengthening defense and diplomatic capabilities.
Local government grants and energy subsidies are key elements of the plan, and households are expected to receive roughly 7,000 yen over the next three months.
The government also aims to raise defense spending to 2% of GDP by 2027.
An additional budget is expected to be approved before year-end, though the ruling coalition currently holds only 231 of the Lower House’s 465 seats.
Support has arrived amid a period of weak growth.
Japan’s GDP fell 0.4% in Q3 2025, equivalent to an annualized contraction of 1.8%.
Inflation has remained above the Bank of Japan’s 2% target for 43 consecutive months and reached 3% in October 2025.
Policymakers expect the new measures to raise real GDP by about 24 trillion yen and generate an overall economic effect approaching $265 billion.
Rising market pressures
The fiscal stimulus has intensified concerns about long-term debt sustainability and market stress.
The five-year credit default swap for Japanese government debt reached 21.73 basis points on 20 November, marking a six-month high.
The country’s 40-year bond yield jumped to 3.697% shortly after the announcement and climbed further to 3.774% on Thursday.
Each 100 basis-point rise in yields increases the government’s annual financing cost by roughly 2.8 trillion yen, highlighting the growing strain on public finances.
Nikkei warned of caution around prolonged post-crisis fiscal stimulus, adding another layer to investor concerns.
The debate has become more acute as the yield curve shifts and Japan’s borrowing costs rise.
These moves also matter for the roughly $20 trillion yen-carry trade. Investors typically borrow yen at low rates to invest in higher-yielding markets abroad.
A combination of higher yields and sudden currency moves could force unwindings.
Historical data indicate a 0.55 correlation between reversals of yen-carry trades and declines in the S&P 500, adding another potential source of volatility.
Yen reaction
The yen plunged sharply after the stimulus announcement, fueling speculation about the currency’s future stability and the potential for official intervention.
October exports rose 3.6% year-on-year, but that increase did little to ease broader concerns about economic pressure.
The scale of fiscal support and persistent inflation are now central to how global markets interpret Japan’s next moves.
Crypto shift
These developments are feeding directly into crypto markets.
A weaker yen tends to push Japanese investors toward alternative assets, including Bitcoin, particularly during periods of rising liquidity.
Analysts note that Japan’s decision comes as the global backdrop already features potential Federal Reserve easing, shifting cash flows in Treasuries, and ongoing liquidity support from China.
Taken together, these factors could bolster crypto demand into 2026.
At the same time, higher long-term yields pose risks.
If yen-carry trades unwind rapidly, institutions might be forced to sell assets—including Bitcoin—to meet liquidity needs, creating sharp downward pressure in some markets.
