After industry pushback, the FCA halved its stablecoin capital requirement from 2% to 1% of issued value in its finalised 2026 rules. Here's what that number actually means, why it was cut, and whether it makes UK stablecoins safer or riskier for you.
Important Risk Warning
This is not financial advice. Cryptocurrency investments are highly volatile. The value of your investment can go down as well as up, and you could lose all the money you invest. Don't invest unless you're prepared to lose all the money you put in.
In its finalised 2026 rules, the FCA cut the capital requirement for stablecoin issuers from 2% to 1% of the value of coins they've issued, after significant pushback from the industry. In plain terms: a firm issuing a sterling or dollar stablecoin in the UK must hold its own capital equal to 1% of the coins in circulation, as a financial buffer on top of the reserves backing the coins themselves. Halving it lowers the cost of issuing stablecoins in the UK — a pro-industry move that the FCA framed as keeping Britain competitive without, it argues, meaningfully weakening protection. Whether that's the right call is genuinely debatable.
It's a technical-sounding tweak, but it says a lot about the balance the FCA is trying to strike: attract crypto business to the UK, while still protecting consumers. Let's unpack what the number does.
It's a buffer of the issuer's own money, sized as a percentage of the stablecoins they've issued, meant to absorb shocks. Separate from the reserves that actually back each coin 1:1, this capital requirement is an additional cushion of the firm's own funds, so the business can withstand losses or operational problems without the stablecoin breaking its peg. Set at 2% in earlier proposals, it's now finalised at 1% in the FCA's stablecoin rules (PS26/10).
Think of it as a solvency margin for the issuer, on top of the pound-for-pound backing. The reserves are what make the coin redeemable; the capital requirement is what keeps the issuer itself robust. A higher percentage means a bigger safety margin but a costlier business; a lower one means cheaper issuance but a thinner cushion. That's the trade-off the FCA just adjusted. Our stablecoin regulation deep dive covers the wider framework.
Industry pushback — issuers argued 2% was too costly and would push stablecoin business away from the UK. Stablecoin firms and industry groups lobbied that a 2% capital charge, on top of full reserves, made UK issuance uncompetitive versus other jurisdictions. The FCA, which has publicly framed its regime as cementing the UK as a "global hub" for crypto, cut the figure to 1% in the final rules — a clear signal it's weighing competitiveness heavily.
Supporters say 1% is still a real buffer and that overly strict rules would simply drive issuers offshore, leaving UK consumers with less-regulated options. Critics counter that halving the cushion trims consumer protection to please industry. Both have a point, honestly — it's a judgement call, and reasonable people land differently. What's clear is that the FCA chose the more issuer-friendly number. Our £40 billion stablecoin cap piece covers another contested design choice.
Marginally thinner protection on paper, but the bigger safety factors are the reserves and whether the issuer is regulated at all. The capital requirement is one layer among several. What actually protects a stablecoin holder most is that each coin is genuinely backed 1:1 by high-quality reserves, and that the issuer is authorised and supervised. A 1% versus 2% issuer buffer is a second-order detail next to those.
For UK users, the more important development is that stablecoin issuers will need FCA authorisation under the new regime at all — a big step up from the current situation. The reserve rules and redemption rights matter more to your day-to-day safety than the capital percentage. And remember the tax quirk that catches Britons out: swapping pounds into a dollar stablecoin and back can create a taxable gain on the currency move, as our USDT vs USDC guide and are stablecoins safe guide explain.
What is the FCA's stablecoin capital requirement? It's a buffer of the issuer's own funds, set at 1% of the value of stablecoins they've issued, separate from the reserves backing each coin 1:1. It's a solvency cushion meant to help the issuer withstand losses without the stablecoin losing its peg.
Why did the FCA cut the requirement from 2% to 1%? After industry pushback arguing that 2% made UK stablecoin issuance too costly and uncompetitive. The FCA, which frames its regime as making the UK a global crypto hub, halved the figure in its finalised rules to balance protection against competitiveness.
Does a lower capital requirement make stablecoins less safe? It slightly thins one protective layer, but the bigger safety factors are whether each coin is genuinely backed 1:1 by quality reserves and whether the issuer is FCA-authorised. A 1% versus 2% issuer buffer is a minor detail next to full reserves and supervision.
Are UK stablecoins now regulated? Under the new regime, stablecoin issuers will need FCA authorisation, with rules finalised in 2026 and the full regime live from 25 October 2027. That's a significant step up from the current position, where stablecoins have been largely outside direct FCA product regulation.
Do I pay tax on stablecoins in the UK? You can. Swapping pounds into a dollar-pegged stablecoin and back can create a capital gain or loss on the currency movement, and using stablecoins in trades is a disposal. Keep records. Our USDT vs USDC guide covers the tax quirk in detail.
Don't lose sleep over 1% versus 2% — for you as a holder, what matters is using stablecoins from issuers that are properly regulated and genuinely back their coins 1:1, plus remembering the UK tax angle on stablecoin swaps. Watch which issuers seek FCA authorisation under the new regime. This isn't financial or tax advice. For choosing between the big stablecoins, read our USDT vs USDC guide.
