Japan 10-Year Bond Yield Hits 30-Year High as Bitcoin Stabilizes Near $78,000

Japan’s 10-year government bond yield surged to 3 percent on Tuesday, marking its highest level since 1996. The 30-year yield also climbed to a record 4.18 percent, while the 10-year US Treasury yield reached 4.78 percent. Amid this global sovereign debt sell-off, Bitcoin has traded sideways near $78,000 following a minor corrective decline.

The Debasement Narrative

The bond market turbulence follows US Treasury Secretary Scott Bessent’s announcement that the maximum size of debt buyback transactions will increase to $4 billion starting in September. Market observers note this resembles a form of yield curve control, reviving the currency debasement narrative closely watched by cryptocurrency and precious metals investors.

Policymakers in Tokyo and Washington face a complex dilemma regarding the Japanese yen. Japan cannot raise policy rates without triggering operating losses for its Finance ministry, nor can it repatriate capital without divesting the US Treasury securities that underpin American financing.

Industry figures like Arthur Hayes have long argued the Federal Reserve will eventually deploy its Foreign and International Monetary Authorities repo facility. This mechanism would allow Japan to borrow dollars against its Treasury holdings to strengthen the yen, though it would simultaneously inject new dollar liquidity into the system, supporting the case for holding Bitcoin and gold.

The current dynamic has drawn sharp criticism from macroeconomic observers. Robin Brooks, a senior fellow at the Brookings Institution, noted on X that Japan has endured a “Liz Truss” bond market crisis for two years, where the currency falls even as yields rise, calling the unprecedented G10 sovereign situation “deeply destabilizing.”

Technical Resistance and Geopolitical Risks

Despite renewed interest in the debasement trade, Bitcoin faces immediate technical hurdles. A thick band of resistance remains between current levels and $86,000, establishing the $76,000 to $82,000 range as the primary battleground for market direction in the coming weeks.

Broader risk assets are also feeling the pressure from escalating geopolitical friction. S&P 500 index futures dropped 0.3 percent to hover around 7,660, their lowest point since August 4. Concurrently, oil prices jumped more than 2 percent, with WTI crude near $88 per barrel and Brent above $92, driven by renewed US-Iran fighting, tanker incidents in the Strait of Hormuz, and comments from President Donald Trump.
