OKX is one of the world's largest cryptocurrency exchanges by trading volume, with a broad range of crypto assets, derivatives, and Web3 tools. However, it holds no FCA authorisation to offer crypto asset services in the UK, which is a significant regulatory gap for British users. UK consumers use OKX without the protections afforded by FCA-regulated platforms, including no FSCS compensation scheme coverage.
OKX, operated by Aux Cayes FinTech Co. Ltd and headquartered in the Seychelles, is one of the world's top five cryptocurrency exchanges by spot and derivatives trading volume. Founded in 2017 and originally known as OKEx, the platform serves tens of millions of users globally and offers spot trading, futures, options, staking, NFTs, and a non-custodial Web3 wallet. It is a well-established name in the crypto industry with a substantial operational track record.
The critical concern for UK consumers is that OKX does not appear on the FCA's register of approved cryptoasset businesses, meaning it is not authorised to offer crypto services in the UK under current money laundering regulations. This leaves British users without the regulatory protections that FCA-registered firms must provide, and there is zero FSCS coverage for any losses. OKX does publish Proof-of-Reserves data to demonstrate solvency, and it holds licences in other jurisdictions including Dubai, but these do not extend UK consumer law protections to British users.
UK consumers considering OKX should be fully aware they are using an offshore, unregulated-in-UK platform with no formal recourse through UK financial regulators if something goes wrong. High-risk products like perpetual futures and leveraged tokens carry substantial loss potential. If you proceed, limit exposure to funds you can afford to lose entirely, use the non-custodial wallet where possible to retain control of your assets, and keep records of all transactions for HMRC tax reporting purposes.
