The U.S. 10-year Treasury yield (US10Y) has surged approximately 48 basis points since the Iran war began on February 28, 2026, reaching levels not seen since the summer of 2025. The benchmark rate closed at 4.39% on March 20 and opened the week of March 23 near 4.40%. This rapid climb mirrors the bond sell-off around "Liberation Day" in April 2025, an event that forced policy changes from the Trump administration.
The 4.5% yield level is seen as a critical threshold. In April 2025, when the 10Y yield surged past 4.50% and broke above 4.60%, President Trump implemented a 90-day pause on reciprocal tariffs on April 9. Analysts, including those from The Kobeissi Letter, warn that the bond market is now dictating how long Trump can maintain pressure in the Iran War, having overtaken oil prices as the primary market threat. Adam Kobeissi highlighted that the U.S. economy "cannot handle a 5% 10Y note yield." This sentiment is echoed by experts like former investment banker Simon Dixon, who stated Trump has "no choice but to crash oil and bond yields by announcing a deal" in the Middle East.
The rising yields exert significant pressure on Bitcoin (BTC) and gold through several macroeconomic channels. Higher yields make U.S. Treasuries more attractive relative to non-yielding assets like BTC and gold, increasing the opportunity cost of holding them. Furthermore, rising yields tend to strengthen the U.S. Dollar Index (DXY), which recently broke above 100, making dollar-denominated assets more expensive for international buyers and applying downward pressure. There is also a discount rate effect, where higher real yields compress the present value of BTC's future growth expectations.
The correlation between rising yields and falling prices for BTC and gold has been a consistent macro pattern in 2025 and 2026. While the two assets do not always move in lockstep—gold can outperform during risk-off episodes due to its traditional safe-haven status—the directional pressure from yields is clear. The situation places the bond market in control of both policy and asset prices. A yield rollover on de-escalation news or dovish Federal Reserve signals could trigger sharp relief rallies in BTC and gold. Conversely, a continued acceleration above 4.5% risks deeper drawdowns for BTC and steeper losses across the crypto market.
