Government bond yields in the United States and Japan have climbed to levels not seen in years, drawing renewed attention to the rising cost of borrowing across global markets and to what higher rates could mean for risk assets such as Bitcoin.

The U.S. 30-year Treasury yield rose above 5.33% this week, its highest level since 2007, while the 10-year yield moved above 4.74%. In Japan, the 10-year government bond yield approached 2.93%, its highest level since the 1990s and a level unseen since 1996. Yields have also risen across major European bond markets.

Drivers Behind the Rise

Investors have pointed to several factors behind the increase, including inflation concerns, increased government borrowing, and a surge in corporate debt issuance tied to artificial intelligence investment.

Higher energy prices have added to concerns about the future path of inflation, while governments continue to issue large amounts of debt to finance budget deficits. At the same time, technology companies are turning increasingly to bond markets to fund the expansion of AI infrastructure.

Alphabet, Amazon and Meta had sold nearly $195 billion in bonds by early July, a 79% increase from the same period a year earlier. The tech giants are also expected to spend more than $730 billion in 2026, with much of that investment directed toward AI infrastructure.

The heavy supply of new debt is landing in markets where years of central-bank balance-sheet runoff have already reduced the amount of liquidity in the financial system, adding to the pressure on yields.

Higher Yields Put Crypto's Liquidity Exposure in Focus

For crypto investors, rising bond yields can make safer fixed-income assets more appealing while increasing borrowing costs across financial markets. That can put pressure on demand for riskier assets such as Bitcoin.

Higher yields do not necessarily mean Bitcoin prices will fall. But if borrowing costs remain elevated, they could influence how investors allocate money between bonds and higher-risk assets, including cryptocurrencies.

The impact could vary across the crypto market. Bitcoin has attracted more institutional interest than many smaller digital assets, while individual cryptocurrencies can respond differently to changes in global liquidity. Those ties to traditional finance have deepened since January 2024, when U.S. regulators approved spot Bitcoin exchange-traded funds, giving conventional investors a direct way to gain exposure and linking Bitcoin's flows more closely to conditions in mainstream markets.

Japan Adds to Global Funding Concerns

Japan is also drawing attention as its government bond yields rise. Higher borrowing costs could make the yen carry trade less attractive, a strategy in which investors borrow yen at relatively low rates and put the money into higher-yielding assets overseas.

Any shift in that trade could affect demand for riskier assets globally, although its direct impact on Bitcoin and other cryptocurrencies is difficult to measure.

The sensitivity is not purely theoretical. In August 2024, a Bank of Japan rate increase contributed to a partial unwinding of yen-funded positions and a sharp sell-off across global risk assets, during which Bitcoin briefly fell below $50,000.

The growing investment in artificial intelligence is adding to financing needs. RBC Global Asset Management said in June that AI infrastructure would require substantial new capital, with a significant share expected to come through bond markets.

Why This Matters

Higher bond yields can pull capital toward relatively safer fixed-income assets and raise the cost of leverage, creating a less supportive liquidity backdrop for Bitcoin and other crypto assets.

The key risk is whether sustained high yields and a potential unwinding of yen-funded positions reduce the global liquidity that has supported crypto demand. In the near term, market participants are watching coming government bond auctions, funding plans and central-bank policy decisions for signals about how long borrowing costs could stay at these levels.
