Staking & Yield in the UK: The Custody Trap
Published 18 May 2026
Staking and yield-earning programmes appeal to crypto holders seeking passive returns. But the UK regulatory environment is shifting, and there is a significant difference between staking on-chain — where you retain control of your keys — and depositing assets with a platform that stakes or lends them on your behalf. The phrase "Custody Trap" is a descriptive label used here to highlight the risks of the latter; it is not an official regulatory term.
- On-chain self-staking is outside the scope of FCA regulation under CP25/40 proposals
- Custodial staking and lending is likely to become a regulated activity requiring authorisation
- Platform failures in 2022–23 demonstrated the scale of custodial counterparty risk
- Staking rewards are generally taxable as income at the point of receipt — see the tax guide
The regulatory context
FCA CP25/40 and the UK framework
In December 2025 the FCA published Consultation Paper 25/40 (CP25/40), its proposals for a comprehensive regulatory framework covering cryptoasset activities in the UK. For staking specifically, the consultation draws a clear line between two types of activity:
- Self-staking — where an individual participates directly in network consensus, using their own wallet or a non-custodial validator service, retaining control of their private keys — is proposed to remain outside the scope of FCA regulation.
- Custodial staking and lending — where a platform holds customer assets and stakes or lends them — is proposed to become a regulated activity. Firms would need FCA authorisation, must provide clear risk disclosures, obtain explicit client consent, and comply with rules on marketing and collateralisation.
CP25/40 is a consultation, not final rules. The framework is expected to be implemented progressively from 2026 onwards. Monitor FCA announcements for updates as the rules are finalised.
What this means
Staking yield is not interest — it's a reward for participating in network consensus, and carries different risk and tax treatment than savings products. Slashing risk means yield is not guaranteed. This is context, not advice.
On-chain staking
Protocol staking — how it works
Protocol staking involves locking tokens on a proof-of-stake blockchain to participate in network validation. According to staking infrastructure provider Figment, protocol staking is a more conservative and reliable way to earn returns than liquidity or lending schemes. Tokens remain under the control of the staker via their own wallet; rewards come from the network itself rather than from a commercial counterparty.
For most proof-of-stake networks, self-staking requires either running a validator node directly (which involves technical setup and minimum stake requirements) or delegating to a validator — where you instruct the network to direct your staking weight to a chosen validator while your keys remain in your own wallet. Non-custodial hardware wallets that support staking are covered in the wallet series; the air-gapped device guide covers options for cold-storage staking.
Risks with on-chain staking are limited to network-level slashing penalties (a reduction in stake if a validator misbehaves) and smart-contract vulnerabilities. These are meaningfully different from the platform-level risks of custodial products.
The FCA's inclusion of staking services within the proposed FSMA authorisation regime means that platforms offering staking to UK users will need regulatory approval — bringing yield products closer to traditional financial oversight.
Custodial products
Exchange staking and lending programmes
Many exchanges and platforms offer staking or "earn" products where customers deposit tokens and the platform stakes or lends them on their behalf. In exchange, the platform pays a yield. These products create custodial risk: if the platform fails, is hacked, or mismanages funds, customer assets may be lost entirely. Unlike bank deposits, there is no FSCS protection for crypto assets held with an exchange.
The scale of this risk was demonstrated during the 2022–23 market downturn, when multiple major custodial lending platforms — including Celsius, BlockFi and Voyager — entered insolvency, leaving customers unable to withdraw assets. Recovery for creditors was partial at best and took years.
Regulatory changes have already affected UK customers. In response to the FCA's financial promotion rules implemented in 2023 and 2024:
- Nexo terminated crypto cash-back and referral programmes for UK users
- PayPal temporarily paused crypto sales in the UK
- Bybit stopped accepting new UK customers
- Luno suspended certain crypto investment products
These are historical examples illustrating how regulatory tightening can affect product availability. Always check current platform announcements before relying on a yield product.
Side-by-side
On-chain vs custodial: key differences
| Feature | On-chain (self) staking | Exchange / custodial staking |
|---|---|---|
| Control of private keys | You retain your private keys and delegate to a validator. Rewards are paid directly by the network. | Your tokens are deposited with a third party, which controls the keys and generates yield as it sees fit. |
| Counterparty risk | Minimal — limited to network slashing penalties or smart-contract failures. | High — you are exposed to the platform's solvency, security and operational decisions. Platform failure may mean total loss. |
| Regulatory status (UK) | Self-staking is proposed to remain outside FCA regulation under CP25/40. | Custodial staking and lending are proposed to become regulated activities requiring authorisation. |
| Returns | Generally lower and more predictable — based on network inflation and transaction fees. | May carry higher advertised yields, but returns depend on the platform's business model and reflect higher risk. |
Tax note
Staking rewards and HMRC
Staking rewards are generally treated as miscellaneous income by HMRC at the point of receipt — the GBP value of tokens received is taxable in the tax year they are received, regardless of whether you sell them. When you later dispose of those tokens, any increase in value since receipt is subject to Capital Gains Tax. Full detail is in the Crypto Tax 101 guide.
Practical guidance
Tips for UK stakers
- Understand the product before depositing: Is the platform staking on your behalf (with your keys held by them), or are you lending tokens to borrowers? Read the terms carefully, including redemption conditions and lock-up periods.
- Consider hardware wallets for self-staking: To stake on-chain, you need a wallet that supports delegation to validators. Hardware wallets and non-custodial solutions keep your private keys under your control. See the wallet series for options.
- Diversify and limit exposure: Do not concentrate holdings in a single platform. Keeping assets spread across on-chain and custodial options, with a portion in cold storage, reduces the impact of any single point of failure.
- Monitor regulatory changes: CP25/40 proposals are not yet final rules. As the UK framework is implemented, platform products may change or require new authorisations. Keep up to date with FCA announcements and communications from your chosen platform.
