Stablecoins

What it is

Stablecoins are blockchain tokens built to hold a steady value by tracking a reference asset — most often the U.S. dollar, one token to one dollar. The leading ones are fully reserved: every token in circulation is backed by cash and short-term U.S. Treasuries that the issuer holds and reports on. That pairing — the stability of the dollar with the speed and global reach of a blockchain — is what makes them useful for moving and holding value.

Holding it in a self-directed IRA

Stablecoins are held for the account through the platform’s qualified digital-asset custody — in the account’s name, not in a personal wallet. Purchases, sales, transfers, and conversions settle into the account, and balances and cost basis are recorded.

Requirements

Held in the account’s name through qualified digital-asset custody — you don’t hold the private keys.
Transfers, conversions, and any yield settle into, and are funded from, the account.
Only stablecoins the custody arrangement supports can be held.

Limitations and prohibitions

The IRS treats digital assets as property (Notice 2014-21), so converting or spending a stablecoin can create a gain or loss; in a retirement account, the usual prohibited-transaction rules apply.
A stablecoin is only as sound as its reserves and its issuer — a token can lose its peg if reserves fall short or confidence breaks.
Stablecoins are not bank deposits and are not FDIC-insured.
The federal framework is new (the GENIUS Act of 2025); rules and the set of supported tokens are still developing.

Valuation and liquidity

Fiat-backed stablecoins are designed to sit at $1, but the peg is a target, not a guarantee — well-reserved tokens have held it closely, while weaker, thinly-backed designs have broken. Liquidity is generally deep for the major regulated stablecoins.

Tax considerations

Favor regulated, fully-reserved, dollar-backed stablecoins with transparent reserve reporting. Know who the issuer is, what backs the token, and your redemption rights before you hold size — and read the full guide below.

A worked example

You hold 25,000 units of a dollar-backed stablecoin in your account and send $25,000 to a counterparty in minutes for a fraction of a cent — versus a wire that costs more and settles in days. Because the token tracks the dollar 1:1, there’s almost no price movement; but if you had acquired it slightly below $1 and it redeemed at $1, that small difference is a taxable gain.

IRS forms & records

Form 1099 information reporting may apply to digital-asset transactions.
Form 8949 and Schedule D — to report any gain or loss on conversion or disposal.
In a retirement account: Form 5498 (year-end value) and Form 1099-R (distributions).

Common mistakes that can cost you

Treating a stablecoin as an insured bank dollar — it is an issuer’s promise backed by reserves, not a deposit.
Ignoring the tax on conversions — swapping or spending a stablecoin can be a taxable event.
Reaching for an algorithmic or thinly-reserved token in the name of ‘stability’ — those are the designs that have de-pegged.
In an IRA, taking personal custody of the keys — a deemed distribution.

Before you invest

The token is a regulated, fully-reserved, fiat-backed stablecoin.
You know the issuer, what backs the token, and your redemption rights.
It is held through qualified custody in the account’s name.
You understand the tax treatment of conversions and of any yield.
