Bitcoin Lags Treasuries as IBIT/TLT Ratio Falls to 81
Bloomberg Intelligence strategist Mike McGlone says Bitcoin’s performance against long-term US Treasury bonds could offer a warning signal for crypto markets. The IBIT/TLT ratio, comparing BlackRock’s spot Bitcoin ETF with the long-term Treasury ETF, stood at 81 on October 30, down 19% from its end-2024 baseline of 100. It has not held above that level since the fourth quarter of 2025. McGlone also noted that IBIT is typically about four times as volatile as TLT.
Bitcoin traded at $78,101 on November 1, 2026, up 1% over 24 hours but down 9.25% over 30 days. The Crypto Fear & Greed Index was 34, indicating fear. McGlone said continued Bitcoin weakness below $80,000 could raise concerns about the wider crypto market, but framed this as a warning rather than a forecast.
The IBIT/TLT ratio measures relative ETF performance; it does not directly show Bitcoin’s dollar value or explain why the funds have moved differently. Traders are watching both the $80,000 Bitcoin level and the ratio’s 100 baseline for signs of market direction.
Bearish
The report is a cautious signal for Bitcoin and crypto sentiment, rather than a confirmed market catalyst. Bitcoin is below $80,000, down 9.25% over 30 days, and the IBIT/TLT ratio is 19% below its baseline. Combined with a Fear & Greed reading of 34, these indicators suggest investors may remain defensive and could limit near-term risk-taking. If Bitcoin stays below $80,000 and the ratio remains under 100, traders may interpret that as continued relative weakness, potentially adding selling pressure or delaying recovery attempts.
Similar periods of Bitcoin underperformance against lower-volatility assets have often coincided with reduced risk appetite, although the comparison alone does not establish the cause or predict the next price move. The ratio tracks ETF performance, not Bitcoin’s direct valuation against the dollar or changes in Treasury yields. IBIT’s stated higher volatility also means the ratio can move sharply in either direction.
In the short term, traders may watch the $80,000 threshold, ETF flows, and broader market sentiment for confirmation. A sustained move back above $80,000 and a recovery in the ratio could ease concerns; further weakness could weigh on crypto assets. Longer term, the ratio may help investors assess relative performance, but it is not by itself evidence of a structural decline or a reliable forecast.
