DeFi Total Value Locked Has Fallen 49% Since October 2025 as Sentiment and Prices Retreat
Decentralized finance protocols collectively held 49% less total value locked on May 17, than they did in October 2025. The contraction spans the major lending platforms, decentralized exchanges, and yield infrastructure that make up the sector’s capital base. Ethereum (ETH), the primary host chain for DeFi activity, has also declined in price over the same period, compressing TVL in dollar terms.
The scale of the decline is large enough that price movement alone does not account for all of it.
What the TVL Numbers Show
Total value locked, the aggregate dollar value of assets deposited into smart contracts across DeFi protocols, is a standard measure of capital commitment to the sector. A fall of 49% in approximately seven months reflects two overlapping forces.
The first is price depreciation: if Bitcoin (BTC) and Ethereum fall in dollar value, the TVL of protocols holding those assets falls even without any user withdrawals. The second force is actual capital withdrawal, where depositors remove assets from protocols entirely.
A 49% decline is too large to be attributed to price movement alone. Data from DefiLlama, the primary TVL aggregator for the sector, shows that both forces are present in the October 2025 to May 2026 contraction.
Active depositor counts and protocol revenue figures have also declined, which are metrics that do not move with token prices.

The Sentiment Component
DeFi participation is highly sensitive to speculative sentiment. During rising markets, yield-seeking capital flows into protocols because the expected return from liquidity provision, lending, and staking exceeds the opportunity cost of holding assets directly.
During falling markets, that calculus reverses. Users who deposited assets expecting yield on top of price appreciation find that price depreciation overwhelms the yield, producing net losses in dollar terms.
This creates a feedback loop. Falling TVL reduces liquidity depth in pools, which widens spreads and reduces fee income for liquidity providers, which makes the protocols less attractive and drives further withdrawal.
The October 2025 to May 2026 period shows this pattern clearly. The sector entered the period near a local TVL peak, driven by the post-election Optimism (OP) that followed the US election results in November 2024, and has contracted steadily since.
Background
DeFi’s TVL peaked in November 2021 at approximately $180 billion before collapsing by more than 80% through 2022, in a contraction closely tied to the collapse of the Terra ecosystem and the broader bear market.
The sector recovered partially through 2023 and 2024, with TVL reaching new local highs in late 2024 and early 2025 as Ethereum and Bitcoin prices recovered. The October 2025 local peak followed a period of elevated institutional interest, driven partly by the approval and growth of spot Bitcoin (BTC) and Ethereum ETFs in the US market.
The current contraction represents a reversion from that elevated baseline. A prior analysis of the Intesa Sanpaolo institutional trade, which involved direct XRP ETF exposure, illustrates how institutional appetite has shifted toward simpler, more liquid cryptocurrency instruments and away from complex DeFi positions.

Which Protocols Are Most Affected
The TVL decline is not uniform across the sector.
Lending protocols, which hold collateral against loans, are typically the most sensitive to price declines because falling collateral values trigger liquidations and reduce borrowing demand. Decentralized exchanges see TVL fall alongside price because liquidity providers hold token pairs whose combined value drops.
Liquid staking protocols, where users deposit ETH in exchange for a staking receipt token, are somewhat more resilient because the withdrawal mechanism is slower and the yield is derived from validator rewards rather than fee income. The DeFi TVL decline tracked by DefiLlama shows lending and DEX categories absorbing the largest absolute dollar losses in the October 2025 to May 2026 period.
What to Watch
Three factors will determine whether the contraction continues or stabilizes.
First is Ethereum’s price, which has an outsized effect on TVL because most major protocols are Ethereum-based. Second is the progress of the CLARITY Act in the US Senate, which would define the regulatory status of many DeFi protocols for the first time.
A positive regulatory outcome could attract institutional capital back into the sector. Third is any new protocol category that generates yield from sources outside of pure speculation, such as real-world asset lending or fee-sharing from on-chain activity.
The real-world asset sector, which has grown consistently through the broader TVL decline, may represent the structural floor beneath which total DeFi capital is unlikely to fall.
