Curve Finance's PegKeeper reserve system has pulled back to $15.8 million as of September 10, down from a peak of $65 million recorded on August 27, according to the protocol's Week 37 yield report. The 76% contraction is the second consecutive weekly decline, pulling reserves below any level recorded since they were rebuilt from zero following June's drawdown. Meanwhile, crvUSD supply has climbed to $75.8 million, more than double the $36.7 million recorded at the start of July, though still well below the stablecoin's all-time high of $181 million reached in May 2025. That supply growth has been supported by a low borrowing environment: the average crvUSD borrow rate has run near 2.1%, cheapening the cost of minting and drawing in supply beyond what organic stablecoin demand alone would suggest.

The PegKeeper contracts are autonomous smart contracts that hold pre-minted crvUSD and deposit or withdraw it from Curve liquidity pools to keep the stablecoin's price near $1. When crvUSD trades above $1, the contracts deploy reserves outward and supply rises. When the price dips below $1, the contracts pull back, reducing deployed positions. The current retreat to $15.8 million signals that the mechanism is actively contracting peg support, consistent with crvUSD trading fractionally below parity at $0.9996. The fact that this marks a second consecutive weekly decline reinforces a downward trend rather than a single-week anomaly. A comparable episode played out at the end of June 2026, when reserves fell to zero entirely. As Curve's own July recap noted: "Peg stability reserves stood at zero at the end of June, two months of falling leverage having left nothing for them to do. July put them back to work." That recovery required 24 consecutive PegKeeper deployments across roughly one week.

Yield picture: read the fee line, not just the headline rate

The highest-yielding pool in Week 37 is sUSG/reUSD at 21.5% APY, of which 8.5 percentage points come from trading fees. Two other notable pools, OUSD/USG at 18.1% APY and MUSD/USDC/USDT at 17.9% APY, carry no disclosed fee contribution, suggesting their returns lean more heavily on external token incentives. The remaining portion of the sUSG/reUSD yield is similarly composed of external incentives, which depend on continued governance emissions and prevailing token prices. By contrast, the sUSDx/USDx pool offers 11.0% APY sourced entirely from trading fees, with no incentive top-up. For users evaluating where to deploy stablecoin capital, particularly in markets where yield reliability matters more than yield size, the fee-only pool represents a cleaner benchmark for what Curve generates organically. CRV, the protocol's governance token, is currently trading around $0.30 to $0.36, with veCRV (vote-escrowed CRV, the locked form used for governance and fee sharing) yielding 2.256% annually. Weekly CRV emissions run to approximately 2.22 million tokens, worth roughly $456,000 at current prices. On the lending side, Llamalend's highest supply rate this week is 7.9% on the crvUSD/CRV pair, with 6.5% available on a crvUSD/Swiss franc stablecoin market.

YieldBasis completes fee unification for BTC pools

A governance vote finalised this week brings all three YieldBasis Bitcoin liquidity pools onto a single flat fee rate, replacing a previous tiered structure. YieldBasis is a separate protocol founded by Curve's creator Michael Egorov that runs leveraged BTC liquidity pools on top of Curve's infrastructure. The product is designed to let Bitcoin holders earn yield while limiting impermanent loss (the value erosion that occurs when the price ratio between two pooled assets shifts). The protocol processed $1.97 billion in trading volume in the first half of 2026, distributing LP fees reported at $10.98 million by Crypto Briefing; Bitcoin.com News has reported a figure of approximately $12 million, which may reflect a different measurement period or methodology. TVL sits between $130 million and $180 million. The move to a uniform fee follows an earlier September 1 reduction across pools, intended to attract volume during periods of lower Bitcoin price volatility. A flat fee structure simplifies LP return calculations.

Regional context: infrastructure, not just yield

For users in Nigeria, Pakistan, India, and other markets where stablecoin adoption is growing fastest, Curve's pool depth and peg stability carry implications beyond yield farming. Stablecoins now account for 30% of all on-chain crypto transaction volume globally, according to the Stablecoin Insider Global Adoption Index 2026, with the heaviest adoption concentrated in countries facing high domestic inflation or unreliable banking access. India ranked first in Chainalysis's 2026 Global Crypto Adoption Index, and Sub-Saharan Africa recorded roughly 52% stablecoin adoption growth in 2025, the highest rate of any region globally. Pakistan ranked third in the same index, where chronic inflation above 25% and an economy supported by approximately 10 million freelancers have driven strong stablecoin preference; the country has also established a formal crypto regulatory body, the Pakistan Virtual Assets Regulatory Authority (PVARA), signalling institutional recognition of the sector. Curve functions as the primary deep-liquidity venue for many stablecoin pairs; any degradation in peg stability or pool depth feeds through to the costs borne by protocols and users routing trades through it. Curve's July 2026 deployment on Robinhood Chain, which is expanding beyond the United States, opens an additional access point for retail users in these markets.

Risk monitor Pharos flags that "Bitcoin collateral running through BitGo and Coinbase introduces exactly the centralized custody dependencies crypto-native collateral was supposed to avoid." A March 2026 exploit in the sDOLA/crvUSD LlamaLend market, which triggered hard liquidations for 27 borrowers through oracle manipulation, remains the most significant security incident of the year for the protocol.

What to watch next

The PegKeeper reserve trajectory is the leading indicator to track over the coming weeks. If reserves continue declining toward zero without a corresponding recovery in crvUSD demand above $1, the peg will depend more heavily on interest rate adjustments alone. The July episode showed the system can self-correct, but the process is not instantaneous. For developers and protocols building on Llamalend's isolated market structure, the March oracle exploit warrants active audit attention before integrating new pool configurations. Llamalend TVL surged from $146 million to $243 million between the Week 32 and Week 35 reports, a 66% increase in roughly three weeks, making the concentration of capital there a live concern rather than a theoretical one. On the supply side, crvUSD at $75.8 million and growing warrants close attention: whether the average borrow rate holds near 2.1% will determine whether the current supply trend continues or reverses as credit conditions shift. Finally, the YieldBasis fee unification is the protocol's stated mechanism for attracting volume during lower-volatility periods; whether the flat rate structure delivers a measurable increase in pool activity will be an early test of that thesis.
