DeFi Yield Update — September 21–27, 2026

1 Yield dashboard

2 Week-over-week comparison

Read the change column with a tolerance of roughly ten basis points. Inside that band you are mostly looking at sampling noise: which pools were included, when each venue reported, and how the weighting moved as TVL shifted between pools.

The rows that clear it are the two lending leaders. Ethereum's +18 basis points is the largest weekly move since the late-August jump, and Arbitrum's rise to 5.22% keeps it the widest spread in the sample again, on a pool set that keeps growing.

3 Spread over the risk-free reference

Judged as spreads, Arbitrum pays the widest premium at 1.79pp and the ordering otherwise holds: Solana staking's 1.46pp sits well above Ethereum lending's 0.74pp — a staking strategy out-earning most credit strategies in the sample, with a different risk content entirely.

The row that should still give an allocator pause is ETH liquid staking at 2.18%, paying -1.25pp against the reference in the lending sense. That is not a flaw — staking is not a lending strategy, and its return includes token exposure rather than a credit premium. It does mean that choosing it on yield alone misreads what you are buying.

4 Lending rates by market

The spread between venues inside a single chain remains wider than the spread between chains, which is the practical argument for reading pool-level rates rather than chain averages. A composite will always look like something nobody can actually deposit into.

5 Liquid staking yields

Lido remains the dominant route by size, and its rate sits close to the sample average. Where providers differ by more than about twenty basis points, the gap is usually attributable to how much of the yield comes from MEV rather than from protocol issuance — which is also the component most likely to move without warning.

6 Stablecoin yields

Two things determine these levels, and only one is durable. The durable part is underlying real-world rate exposure from tokenized Treasuries. The cyclical part is perp funding, which feeds several of the higher-quoting products and can reverse in a day without anything visibly changing in the pool.

9 What we would watch next week

• Whether the Ethereum lending premium holds near 0.74pp or the re-widening proves to be a one-week event-driven spike.
• Whether the tokenized T-bill reference keeps climbing; it has risen two weeks in a row and does the compression work on its own whenever lending stalls.
• Whether Arbitrum's premium persists as its pool set grows, which would suggest the gap is structural rather than a size effect.
• Whether Solana staking holds its rebound or falls back, which keeps the disinflation question open.

10 In brief

The week's signal was re-widening, the reverse of last week. Ethereum stablecoin lending jumped from 3.99% to 4.17% — an 18-basis-point rise, the largest weekly move since the late-August jump — while the tokenized T-bill reference crept up to 3.43%. The premium over the risk-free rate re-opened to 0.74pp, up from 0.59pp. Last week the compression was almost entirely the reference rate catching up; this week the expansion is almost entirely lending demand doing the work.

That reading fits the week's activity data. Network fees across the sample rose 11.1% while blended turnover fell, and utilisation is the variable that feeds lending rates — borrowers pay for capital that is being used. A one-week coincidence is not a trend, but the direction is the one the fee table pointed to.

Solana staking rebounded from 4.70% to 4.89% — about 0.19pp, inside the MEV-and-tips noise band we have tracked. The blended stablecoin rate rose to 4.11% as Base and Arbitrum pool sets grew, and ETH liquid staking eased to 2.18%.
