Yield Week In Review: September 26, 2025

Yield Week In Review: September 26, 2025

Yield markets advanced further this week, with new stablecoin launches, major valuation moves, and continued protocol innovation keeping momentum high. From USDC expansion to Tether’s headline-grabbing fundraise, stablecoins remained at the center of activity, while new networks and yield strategies reinforced DeFi’s rapid pace of innovation.

Let’s take a closer look at yield developments from this week.

New Yield Support

The Yield.xyz API expanded its coverage this week with two notable additions:

Stablecoin Developments

USDC broadened its footprint with new deployments on Ink and Plume. Ink, Kraken’s Layer 2 built on the OP Stack and part of the Superchain, adds another major exchange-led entry into rollup ecosystems. Plume, an EVM-compatible chain focused on real-world assets, positions USDC to play a central role in tokenized RWA finance.

Meanwhile, Tether is reportedly seeking funding at a staggering $500 billion valuation, underlining the scale and dominance of USDT in global crypto markets.

Finally, Sky Ecosystem saw surging demand for its Sky Savings Rate product. TVL rose 25% this week, climbing from $1B to $1.25B in USDs deposits. The program’s 4.75% APY continues to draw capital and expand Sky’s stablecoin footprint.

Protocol Updates

Pendle markets remain a hub for stablecoin yield strategies. Fixed APYs are drawing strong participation, with returns as high as 25% on USDai and around 9% on USDC, demonstrating ongoing demand for tokenized fixed income.

On the infrastructure side, Plasma rolled out its new Layer 2, immediately attracting stablecoin flows. Ethena’s USDe reached its $1B supply cap on Aave within hours of launch, a signal of both confidence in the product and significant appetite for stablecoin lending on emerging networks.

Flowdesk, a full-service digital asset trading and technology firm, announced its collaboration with Morpho to optimize liquidity and balance sheet management. By integrating Morpho’s lending and borrowing infrastructure, Flowdesk aims to unlock liquidity across majors, LSTs, and altcoins. The firm also plans to deploy capital into Morpho’s yield opportunities to capitalize on low-risk looping strategies.

Finally, Gauntlet unveiled a landmark partnership with DeFiDevCorp (Nasdaq: DFDV), the first publicly traded Solana Digital Asset Treasury (DAT). This initiative will see Gauntlet apply its quantitative risk frameworks to move DFDV’s treasury—anchored in dfdvSOL—beyond traditional staking into advanced, risk-adjusted yield strategies on Drift Protocol.
