Coinbase warns UK of stablecoin limits pushing innovation and activity abroad

Crypto exchange giant Coinbase has sharply criticized proposed United Kingdom stablecoin rules that would cap how much digital currency users can hold, warning the move could put $1.35 billion of its business at risk and weaken the UK’s standing as a global digital finance hub.

In a post on social media platform X, Coinbase CEO Brian Armstrong called parts of the Bank of England’s draft stablecoin framework “innovation blockers,” saying the restrictions could deter investment and push crypto activity to more friendly markets.

The Bank of England plans stablecoin limits that could slow UK digital finance

Under the proposed stablecoin laws, the Bank of England will allow individuals to hold up to £20,000 in major UK stablecoins and businesses up to £10 million. Similarly, stablecoin issuers must store most of their reserves in short-term government debt and central banks.

Bank officials claim the new rules will reduce risk, protect users, and guide companies in handling stablecoins.

However, Armstrong warned that these limits will only push builders, money, and users elsewhere rather than keep them in the UK. He said other countries are already working on clear, more open crypto rules because innovation needs space to expand, so the caps will only slow growth rather than manage risk. 

UK lawmakers had also raised similar concerns in the past, saying strict limits would push companies overseas and drain liquidity from the local markets. 

According to Coinbase, the UK’s banking, trading, and capital markets grew because they allowed innovation to scale, but these stablecoin caps will limit how far users and companies can grow.

Coinbase sees these limits as a direct threat to its business and the future of digital finance in the UK, as stablecoins now generate significant revenue and people already use them for almost all trading activities.

Coinbase says stricter rules could hurt its $1.35 billion stablecoin business

Coinbase made $1.35 billion from stablecoins in 2025, up from $911 million in 2024. Out of this amount, $364 million came in during Q4 alone, even as the company reported a quarterly net loss.

Stablecoins have become Coinbase’s most reliable revenue stream, and the company now uses that money to grow into stocks, tokenized assets, and always-on trading.

At the same time, the rate of growth could increase even further. Analysts have predicted that the revenue generated by Coinbase stablecoins could increase by anywhere from two to seven times due to the new US rules. The new rules allow stablecoins to offer yields, meaning users can receive interest simply by holding stablecoins. 

But while the US is opening up to growth, the UK is placing strict limits on how much people can accumulate. Coinbase says this could cause money, builders, and users to move to more welcoming places. Digital finance is an evolving space, and when one region slows, activity shifts elsewhere.

Brian Armstrong has been pushing back against regulations in other areas as well. He says that regulations concerning stablecoins are not solving a problem but are slowing growth. There is a fear among banks that stablecoins can generate interest that could divert from traditional bank accounts.

So, Coinbase is caught in a dilemma between growth and control.

But that gets us back to where we started. Stablecoins are already facilitating real-money transactions in real time. Stablecoins are used for payments, money transfers, and keeping markets functioning. And if stablecoins are an integral part of the system, then restrictions might prevent large institutions from participating.

Coinbase believes this is a defining moment. The UK could establish a framework to support the development of stablecoins with appropriate guardrails. Alternatively, it risks falling behind the next stage in finance.
