The 10-year US Treasury yield touched 5.34% on Oct. 1, its highest level since 2002, capping a third quarter in which it climbed almost 90 basis points — the largest quarterly rise this century. Bitcoin gained roughly 43% over the same three months and Ethereum about 71%, and Bitcoin now trades in the mid-$80,000s. The price survived the bond shock. The financing built around it did not.

A 5% yield raises the bar, and Q3 buyers cleared it

The Federal Reserve's H.15 release for Oct. 1 put the 10-year at 5.29%, the 30-year at 5.64%, and the 10-year real yield at 2.93%. Inflation-adjusted returns on government debt now compete directly with a coupon-free asset like Bitcoin.

Bond yields hit new highs across the US, France, Germany, Japan and the UK, where 30-year borrowing costs reached 6% for the first time since 1998. Brent crude moved back above $100 a barrel. Against that backdrop, US-traded spot Bitcoin ETFs drew about $6.3 billion in the third quarter, and Ethereum ETFs about $3 billion.

Citi raised its 12-month Bitcoin forecast to $113,000 from $82,000, citing stronger crypto activity, ETF inflows, and gradual adviser and brokerage allocations. Higher yields remained a headwind; other sources of demand outweighed it for the quarter. One quarter leaves the long-run relationship open.

The stress showed up in the derivatives market. On Sept. 23, a stronger PMI pushed yields higher, and Bitcoin slipped below $85,000, triggering $135.8 million of long liquidations in a single hour and $510 million over 24 hours. A separate energy shock involving oil, bond yields and Fed expectations forced roughly $568 million in liquidations. The quarter's direction survived both events. Leveraged traders took the damage.

Bitcoin leverage gets repriced

On Sept. 25, open interest on selected exchanges fell 14.3% — about $1.7 billion — as Bitcoin held near $84,000 with the 10-year at 5.22%. Higher benchmark rates raise the cost of capital for explicit borrowing and for implicit leverage: perpetual futures, basis trades, options structures, and collateralized loans. Macro shocks also lift volatility enough to force deleveraging inside a bull run.

The yield shock now stresses a newer structure: Bitcoin treasury companies. These firms fund purchases through common equity, preferred stock and convertible debt, according to Skadden. The model works when shares trade at a premium to net asset value, because selling stock for more than the crypto behind it buys more crypto per share.

Goodwin describes the sector's compression from premium valuations to NAV or below. Many treasury companies now trade at or below NAV, and business models that depend on premium-priced equity and debt face strain. Higher yields lift the return investors demand on preferred shares and convertibles, widen the risk premium on equity, and offer a higher risk-free alternative. Each raises the hurdle for a financing model that already depended on NAV premiums and cheap hybrid capital.

Treasury yields reach DeFi

Academic research confirms the transmission channel. A 2026 Finance Research Letters study using Aave data found stablecoin borrowing and deposit rates linked to US Treasury yields, with the 10-year showing the most consistent explanatory power across maturities. An ECB working paper on Aave found restrictive monetary shocks reduce both stablecoin borrowing demand and liquidity supply, with transmission depending on the balance between arbitrage and leverage channels.

The competitive math has inverted. In the zero-rate era, a 4% or 5% crypto yield looked attractive against cash paying close to nothing. At a 5% Treasury, DeFi yields must compensate for smart contract, liquidity, counterparty, stablecoin, oracle and governance risk — meaning products need higher returns, leverage, token incentives, or different liquidity structures to compete.

The tokenized end of the market is expanding into that gap. RWA.xyz lists 108 tokenized US Treasury fund products, including USYC, USDY, BUIDL and iBENJI. The San Francisco Fed estimates stablecoin issuers' Treasury holdings could roughly double to about $400 billion by 2030 if recent growth continues.

Where Bitcoin and its plumbing go from here

Two paths define the outlook. If the 10-year falls back below 5% as oil and inflation cool, and adviser and brokerage allocations continue, Citi's $113,000 forecast becomes the reference for institutional demand. Treasury-company premiums could reopen, basis trades would improve, and tokenized collateral adoption would broaden — consistent with Citi's tokenization range of $5.5 trillion to $8.2 trillion by 2030.

If yields hold near 5% with real yields close to 3%, Bitcoin can keep rallying in bursts, but each data shock raises the odds of a liquidation flush. Treasury-company discounts would persist, preferred and debt financing would cost more, DeFi borrowing rates would climb, and low-risk DeFi yields would lose appeal against tokenized Treasuries. A disorderly bond or oil move would put the most strain on leveraged perpetuals, crypto-backed loans, and treasury-company debt and preferred stacks.

The 10-year's path through the next few CPI prints and Fed meetings will decide whether crypto's financing markets deleverage again or rebuild on cheaper capital.
