Bitcoin ETFs Shed $485 Million in a Day as the 30-Year Treasury Yield Hits 5.7%

Spot bitcoin ETFs lost $484.9 million on Wednesday, October 7, their largest one-day outflow since June 25, according to Decrypt. The same day, the 30-year Treasury yield rose to about 5.7%, which Decrypt describes as its highest level since 2002. The two moves landed together, and a calm question follows: when the U.S. government will pay you 5% or more to lend it money, what does that do to the case for holding something as volatile as bitcoin?

What happened

• The outflows. BlackRock's IBIT led with $207.7 million out and Fidelity's FBTC followed with $105.1 million, per Decrypt. The day erased about 81% of the inflows from the previous nine sessions.
• The bigger picture. Cumulative net inflows into the funds still stand at $57.8 billion. Month to date through October 7, the funds are down $163.3 million after opening October with $321.6 million in inflows over four sessions.
• The price. Bitcoin fell as low as $81,749.83 on Thursday, about 6% below its $86,978 peak earlier in the week.

Decrypt places the move inside a broader risk-off mood: Brent crude near $100 a barrel, stocks off their record highs, and a Federal Reserve that raised rates in September for the first time since 2023, with minutes showing most officials expect another hike by year-end. Those are Decrypt's reports, and we haven't independently verified each one.

The yield side

The Treasury Department's daily par yield curve gives the official numbers. The 30-year yield closed at 5.67% on October 7, the highest close of the first eight days of October, and eased to 5.60% on October 8.

*Simple arithmetic, not a forecast: yield times $10,000, ignoring compounding, taxes, and price changes. Treasury interest is subject to federal income tax and exempt from state and local income tax, per the IRS.

Why a 5% Treasury competes with bitcoin

Every asset competes for the same pool of money, and a yield sets a benchmark. A Treasury note held to maturity pays a known amount of interest, and Treasuries carry the full faith and credit of the U.S. government. Bitcoin pays nothing, and its return depends entirely on what the next buyer will pay. When a government-backed alternative offers 5% or more, depending on maturity, a volatile asset has a higher bar to clear, because an investor who holds bitcoin is giving up that interest.

That logic is why economists talk about opportunity cost, and it's why rising yields have often coincided with pressure on riskier assets. It is not a mechanical law, though. Bitcoin has moved with stocks, with the dollar, and with its own news at different times, and one or two days of fund flows say little about what comes next.

What the 5% number doesn't tell you

• A Treasury can lose value before it matures. The SEC notes that interest rate risk is common to all bonds, even U.S. Treasury bonds, and that the government does not guarantee a bond's market price. Longer maturities carry more of it. A 30-year bond bought at 5.6% can fall sharply if yields keep climbing.
• Held to maturity, the picture changes. If you hold a Treasury until it comes due, you receive the face value back, regardless of what the market price did in between. Our bond series walks through how that works.
• The two aren't the same job. A Treasury is a way to lend money for a known return. Bitcoin is a bet on adoption and price. Comparing yields alone treats them as substitutes, which they are not.

Questions worth asking, whatever you hold

• What is this money for, and when will I need it?
• If this holding fell by 30% and stayed there for two years, would I be able to leave it alone?
• Did I buy it for a reason that is still true today, or because the price was rising?
• Is it a size that a bad year wouldn't change my plans?

Common questions

Why did bitcoin ETFs have outflows when Treasury yields rose?

Decrypt linked the outflows to a risk-off backdrop that included the 30-year Treasury yield near 5.7%, oil near $100, falling stocks, and expectations of another Fed rate hike. Higher yields raise the return on safer alternatives, which can reduce the appeal of volatile assets, but the relationship isn't mechanical and flows can reverse quickly.

Is a 5% Treasury risk-free?

Treasuries carry the full faith and credit of the U.S. government, so default risk is considered minimal. They still carry interest rate risk: if you sell before maturity, the price may be lower than what you paid. Held to maturity, you receive the face value back.

What was the largest one-day outflow for spot bitcoin ETFs this month?

According to Decrypt, spot bitcoin ETFs lost $484.9 million on October 7, 2026, their largest one-day outflow since June 25. Cumulative net inflows since launch remained $57.8 billion.
