SEC sets 2% haircut for stablecoins

TLDR

The SEC has allowed U.S. broker-dealers to treat certain payment stablecoins almost like cash, using only a 2% capital haircut instead of effectively a 100% deduction.

1. The SECs updated broker-dealer FAQ lets firms count 98% of qualifying payment stablecoin holdings as regulatory capital under Rule 15c3-1, instead of valuing them at zero.
2. This sharply reduces the penalty for holding stablecoins, making it easier for regulated brokers to use assets like USDC for liquidity, settlement and tokenized securities activity.
3. The relief applies only to fully reserved, non-yield payment stablecoins and comes as informal staff guidance, so eligibility, due diligence and future rulemaking are critical to monitor.

Deep Dive

1. What The SEC Actually Changed

The SEC updated its Broker-Dealer Financial Responsibilities FAQ so that broker-dealers can apply a 2% haircut to proprietary positions in certain payment stablecoins when calculating net capital, instead of a de facto 100% haircut that excluded them from capital calculations altogether. In practice, that means a broker can now treat a 100 million dollar qualifying stablecoin position as 98 million dollars of regulatory capital, with 2 million dollars deducted for risk, similar to cash-like instruments such as money market funds. This shift is described in detail in coverage of the new FAQ, which notes that stablecoins like Circles USDC had previously been treated as having no capital value in many firms models.[^1]

2. Impact On Stablecoins And Market Structure

By letting stablecoins count as working capital, the SEC removes a major balance-sheet friction that discouraged broker-dealers from holding or using them at scale.[^1] Reports note that this should make it easier for brokers to fund trading inventory, support client flows and settle trades in payment stablecoins, which in turn supports tokenized securities and on-chain settlement rails.[^2] Industry voices, including Hester Peirce, have argued that a 100% haircut was unnecessarily punitive given high-quality reserves, and that a 2% haircut aligns stablecoins more closely with money market funds in the regulatory toolkit.[^3]

3. Scope, Limits And What To Watch

The guidance applies only to payment stablecoins that are fiat-redeemable at par, fully reserved, and non-yielding; yield-bearing or algorithmic designs are explicitly outside this 2% framework.[^3] It covers broker-dealer proprietary positions, not customer assets in custody, and comes as staff guidance rather than a formal rule, which means it can be modified or reversed more easily than full rulemaking.[^2] Next, the big variables to watch are: which specific stablecoins brokers treat as eligible, how aggressively large firms adopt stablecoin-based settlement, and how this interacts with upcoming legislation like the GENIUS and CLARITY Acts that aim to lock in a broader federal framework for stablecoins.[^3]

Conclusion

The SECs 2% haircut decision is a technical tweak with potentially large consequences, shifting qualifying payment stablecoins from capital dead weight toward near-cash status on broker balance sheets. If adoption follows, this can deepen liquidity, normalize stablecoins inside traditional market plumbing, and accelerate tokenized settlement, while putting a premium on conservative, fully reserved designs that can meet both regulatory and institutional risk standards.
