SKN | Bitcoin Funds Took In $2.5 Billion as Treasury Yields Surged. Is Crypto Ignoring the Bond Market?

Key Points:

• Global digital-asset investment products attracted $3.55 billion in the week ended September 29, with Bitcoin accounting for $2.52 billion, according to CoinShares.
• The 10-year U.S. Treasury yield subsequently reached approximately 5.31%, its highest level since 2002, creating a significant test for non-yielding assets such as Bitcoin.
• The key question is whether recent crypto inflows represent durable institutional demand or a short-term rotation that could weaken if yields remain elevated.

Bitcoin is facing an unusual macroeconomic test: institutional money has poured into crypto investment products even as U.S. Treasury yields have climbed to levels rarely seen in recent decades. Digital-asset products attracted $3.55 billion during the week ended September 29, including $2.52 billion for Bitcoin, before the 10-year Treasury yield reached approximately 5.31%. The divergence raises an important question for crypto investors: has Bitcoin become less sensitive to bond-market competition, or has the adjustment simply not fully reached digital assets yet?

Bitcoin Inflows Have Been Strong, but the Timing Matters

The latest inflow figure was the largest weekly total of 2026, lifting assets under management across digital-asset investment products to roughly $173 billion. Bitcoin captured about 71% of the week’s inflows, while Ethereum attracted $702 million, Solana $193 million and XRP $92.3 million. U.S.-listed products accounted for approximately $3.43 billion, showing that institutional demand was concentrated in the world’s largest capital market.

But the sequence is important. The $3.55 billion arrived before the Treasury yield reached 5.31%. On September 30, Bitcoin investment products subsequently recorded approximately $148.7 million in outflows, suggesting that investors did respond when rates moved to their highest level in years. Bitcoin was trading near $84,600 on October 3, after previously climbing above $87,000 in late September.

A 5.3% Treasury Yield Changes the Opportunity Cost

The bond market remains a fundamental benchmark for institutional portfolios. A 10-year Treasury yield near 5.3% provides investors with a relatively high nominal return without the price volatility associated with Bitcoin. CoinShares noted that the 10-year yield reached approximately 5.34% earlier in the week before easing toward 5.15% following weaker payroll data.

That creates pressure on assets that generate no conventional income. Bitcoin’s investment case depends primarily on capital appreciation, while Treasury securities provide contractual interest payments. Goldman Sachs’ Tony Pasquariello has therefore warned that higher long-term yields are reintroducing pressure on equities and other yield-less assets, including Bitcoin, according to the source report.

Bitcoin Has Not Actually Decoupled From Macro

The recent performance should also be viewed against a longer horizon. Bitcoin has gained approximately 33% over 90 days, but the source notes that it remains down roughly 30% over the previous 12 months. That distinction matters because a strong quarterly rebound does not necessarily establish a structural break from interest-rate sensitivity.

CoinShares’ broader market analysis similarly argues that crypto has not truly decoupled from macroeconomic conditions. Instead, investors appear increasingly focused on whether the policy framework behind elevated yields is sustainable, particularly as fiscal deficits, inflation and Treasury supply push longer-term borrowing costs higher.

The Next Few Weeks Could Provide the Answer

The most important signal will be whether fund inflows remain consistent while Treasury yields stay above 5%. One exceptionally strong week can reflect portfolio rebalancing, tactical positioning or delayed deployment of capital. Consecutive weeks of inflows would provide stronger evidence that institutional demand is becoming less sensitive to the opportunity cost created by government bonds.

Conversely, sustained yields above 5.3% combined with renewed fund outflows would reinforce the traditional relationship between higher real financing costs and pressure on risk assets. For crypto investors, the central issue is therefore not whether Bitcoin can rally while yields rise—it already has—but whether institutional demand can remain durable when the bond market offers increasingly competitive returns.
