Bitcoin surged 43% in the third quarter to trade in the mid-$80,000s even as the US 10-year Treasury yield reached 5.34% on Oct. 1—its highest level since 2002—putting an end to the crypto market's cheap-money era.
Key Takeaways
- Bitcoin gained 43% and Ethereum rose 71% during Q3 despite a 90-basis-point surge in the US 10-year Treasury yield.
- US spot Bitcoin ETFs brought in $6.3 billion in Q3 inflows, while spot Ethereum ETFs attracted $3 billion.
- Citi upgraded its 12-month Bitcoin price forecast from $82,000 to $113,000, citing ETF adoption and brokerage allocations.
- Forced deleveraging wiped out $510 million in long liquidations over 24 hours on Sept. 23 as Bitcoin fell below $85,000.
Sovereign Bond Yields Surge Amid Liquidation Waves
Sovereign bond yields climbed across the US, France, Germany, Japan, and the UK, where 30-year borrowing costs reached 6% for the first time since 1998. Data from the Federal Reserve's H.15 release for Oct. 1 showed the 10-year yield at 5.29%, the 30-year yield at 5.64%, and the 10-year real yield at 2.93%, alongside Brent crude rising above $100 a barrel.
Despite macro headwinds, US spot Bitcoin ETFs recorded $6.3 billion in net Q3 inflows while Ethereum ETFs pulled in $3 billion. The sustained demand led Citi to challenge traditional targets and raise its 12-month Bitcoin forecast from $82,000 to $113,000, referencing broader institutional entry as the fundamental case for $113,000 Bitcoin continues to build.
However, rising yields triggered sharp leverage flushes. A strong PMI print on Sept. 23 pushed Bitcoin below $85,000, causing $135.8 million in long liquidations in one hour and $510 million over 24 hours. An energy-driven shock caused another $568 million in forced liquidations. On Sept. 25, exchange open interest dropped 14.3% as Bitcoin traded near $84,000 with the 10-year yield at 5.22%.
Corporate Treasuries and DeFi Adapt to Higher Rates
Higher baseline interest rates are testing crypto financing structures. Law firm Skadden notes that treasury companies fund holdings using common equity, preferred stock, and convertible debt. However, legal firm Goodwin reports that valuations have compressed, leaving many corporate treasury firms trading at or below net asset value (NAV).
In decentralized finance, a 2026 Finance Research Letters study using Aave data demonstrated that stablecoin borrowing and deposit rates directly link to US Treasury yields. An ECB working paper on Aave similarly established that restrictive monetary policy reduces stablecoin borrowing demand. RWA.xyz now tracks 108 tokenized US Treasury fund products, such as USYC, USDY, BUIDL, and iBENJI. The San Francisco Fed projects stablecoin issuers' Treasury holdings could double to $400 billion by 2030.
Why It Matters
Bitcoin's quarterly rally during a major bond market sell-off proves that direct institutional access through spot ETFs can decouple digital asset prices from macroeconomic headwinds. However, persistent 5% Treasury yields permanently alter crypto funding markets by raising the return hurdle for DeFi protocols and eliminating cheap hybrid capital for corporate treasury models. Going forward, market participants should watch whether persistent NAV discounts force consolidation among public Bitcoin treasury companies or accelerate capital migration into tokenized real-world assets.
