30-Year US Treasury Yield Breaks 5%: Background and Reasons
Since May 2026, the US 30-year government bond yield has continued to climb, repeatedly breaking the key psychological barrier of 5%. This landmark breakthrough marks the first time long-term US Treasury yields have reached such high levels since the eve of the 2007 global financial crisis. Specifically, in May 2026, the 30-year government bond yield surged to 5.046% in an auction; it then broke above 5% again in July and remained there for over two weeks; by August 18, it reached 5.339%, rose to 5.353% on September 10, and further touched 5.36% on September 15, all new highs since 2007.
The reasons driving the rise in long-term US Treasury yields are complex and diverse. The market reacted strongly to higher-than-expected Consumer Price Index (CPI) and Producer Price Index (PPI) data, with investors demanding higher long-term inflation compensation. Furthermore, escalating tensions in the Middle East pushed up oil prices, exacerbating deep market concerns about stagflation risks. High US debt levels and bond issuance by tech companies competing for capital also prompted investors to demand higher risk premiums to hold long-term US sovereign debt. Analysts generally believe that interest rates are returning to historical norms after the Federal Reserve's rate hike cycle concludes.
Bitcoin Market Performance: Capital Outflows and Brief Rebounds
Against the backdrop of continuously rising 30-year US Treasury yields, Bitcoin's market performance has shown complexity. On one hand, high yields put pressure on risk assets. For example, on April 30, 2026, Bitcoin fell to $74,900 after the Federal Reserve meeting and the 30-year government bond yield touched 5%. On May 18, 2026, US spot Bitcoin ETFs saw a single-day net outflow of approximately $649 million, the largest since January, with cumulative outflows reaching $1.6 billion over 10 days, coinciding with the surge in long-term yields. On July 21, 2026, when the 30-year government bond auction yield reached 5.06%, Bitcoin traded slightly above $64,000, down 1.3% in 24 hours. As of September 15, 2026, Bitcoin traded at approximately $75,750, down 3.5% in 24 hours, its lowest price since August 21, with a market capitalization of about $1.52 trillion. This price is still about 40% lower than its all-time high of over $126,000 on October 6, 2025.
However, Bitcoin is not entirely passive. On August 20, 2026, after the US Treasury Department announced increased liquidity support for long-term bond buybacks, Bitcoin jumped from about $64,000 to $70,000, demonstrating sensitivity to specific macro policy changes.

Impact of High Yields on Risk Assets
The prevailing view is that higher government bond yields negatively impact risk assets like cryptocurrencies. When investors can earn a guaranteed 5% return risk-free, their interest in speculative assets naturally decreases. This high discount rate compresses valuations across the entire risk curve, making speculative allocations harder to justify.
For institutional investors, it's a simple arithmetic problem: a 5% risk-free rate can yield 4.3 times the return over 30 years, meaning every Bitcoin allocation must exceed this threshold to justify its place in a portfolio. The attractiveness of this "risk-free rate" causes some capital to flow from risk assets to the relatively safe government bond market.
Controversy Over Bitcoin's Safe-Haven Properties
Bitcoin's status as a safe-haven asset has always been controversial. Some observers believe that Bitcoin exhibits certain safe-haven properties during specific periods of geopolitical tension. For example, during the outbreak of the Iran war in April 2026, Bitcoin prices rose, even as stocks and gold saw capital outflows, leading some to re-emphasize its role as "digital gold."
However, more analyses suggest that Bitcoin remains primarily a risk asset. In 2022 and 2025, Bitcoin showed a high correlation with tech stocks, being considered a "risk asset." Its correlation with global equities is unstable, rising during periods of market stress, which weakens its diversification role. Analyst Hupzy points out that high yields are a structural headwind for Bitcoin and risk assets, as yields above 5% make speculative allocations harder to rationalize. When geopolitical risks suddenly increase, investors typically seek assets they perceive as defensive, with gold historically benefiting. Bitcoin's reaction, however, is less predictable; during periods of high market tension, it may initially behave more like a high-risk tech asset.
Market Sentiment and Future Outlook
Current market confidence in US fiscal discipline and inflation management capabilities is facing severe tests. The breakthrough in the 30-year US Treasury yield not only reflects concerns about inflation but also embodies investors' cautious attitude towards the long-term economic outlook and the government's ability to repay debt. For Bitcoin, it stands at a critical crossroads, where the tension between its narrative as a safe-haven asset and its reality as a risk asset will continue to be tested amidst macroeconomic headwinds.
