UK regulators are moving to implement a nationwide ban on crypto-backed loans, citing growing macroeconomic risks. The Financial Conduct Authority (FCA) has raised red flags over the rapid growth of lending within the decentralized finance (DeFi) sector, warning that it poses significant threats to consumer protection and the stability of the broader financial system. The proposed measures come after months of consultation with central banks, policymakers, and key stakeholders in the crypto industry. As of Friday, the total value locked (TVL) in DeFi lending and staking protocols has surged past $101 billion, underscoring the scale and urgency of the regulatory response.
UK Regulators Target Crypto Lending with Nationwide Ban Over Systemic Risk Concerns
UK financial authorities are set to prohibit cryptocurrency lending across the country, warning that the practice poses growing threats to financial stability and economic integrity—particularly within the DeFi sector and Ethereum’s ecosystem.
In a newly released proposal, the Financial Conduct Authority (FCA) announced intentions to impose a broad ban on crypto-backed borrowing. The move, developed in collaboration with the Bank of England and international regulators, is designed to curb what officials describe as “unchecked expansion” of digital lending platforms that could endanger the wider financial system.
Key concerns include the surge in under-collateralized lending and the increasing reliance on decentralized finance protocols to distribute credit, which regulators argue operate without sufficient oversight.
UK’s Proposed Crypto Lending Ban Raises Concerns Over DeFi Stability and Ethereum’s Market Share
Sarah Pritchard, Executive Director of Markets at the UK’s Financial Conduct Authority (FCA), expressed concern that the rapid growth of crypto lending was outstripping the ability of regulators to keep pace. She emphasized that unregulated financial channels posed a threat to economic stability and could not be allowed to continue unchecked.

Under the new proposal, crypto platforms operating within the UK would be prohibited from issuing loans backed by digital assets, including major tokens such as Ether, Bitcoin, and stablecoins. The draft regulation will be open for a 90-day public consultation period before heading for parliamentary consideration in the third quarter of 2025.
Implications for the Market: Ethereum and DeFi in the Crosshairs
The proposed restrictions are expected to deliver a significant blow to the decentralized finance (DeFi) landscape, especially impacting protocols that rely on crypto-collateralized lending and staking—most of which are heavily built on the Ethereum network.
As of Friday, data from DeFiLlama shows that the total value locked (TVL) in DeFi protocols has reached \$101 billion. Ethereum remains the dominant player with a TVL of \$51.9 billion, commanding roughly 52% of the market. However, that figure marks a notable decline from the 71% share Ethereum held during the peak of the 2021 bull run, as competition from BNB Chain and Tron has intensified.
Leading Ethereum-based DeFi protocols like Aave, Compound, and Lido may experience reduced participation from UK users and tighter capital inflows if the new regulations are enforced. Institutions operating in DeFi may also reassess their engagement due to compliance concerns, potentially limiting broader market access.
Furthermore, staking rewards could decline if borrowing activity slows under the regulatory changes, possibly triggering a ripple effect that undermines liquidity and returns across the DeFi ecosystem.
