Stablecoin Treasury Policy: Which, How Much, and What If It Depegs

Most stablecoin treasury losses are not bad asset picks — they are the absence of a policy: everything in one issuer, no due-diligence cadence, no plan for a depeg. This guide is the policy, not the comparison: eligibility, concentration limits, due diligence, and the contingency.

TL;DR

• A written policy beats picking "the best" stablecoin — it is the durable governance, not a point-in-time call.
• Components: eligibility, concentration limits (per issuer + aggregate), issuer/reserve due diligence, custody rules, depeg contingency.
• Concentration limits are the core control — single-issuer concentration is the dominant risk.
• Due diligence is recurring — issuer status/reserves change (track vs GENIUS / MiCA).
• Depeg contingency is pre-decided — decide calm, not mid-stress.
• Distinct from the asset comparison (#61): the comparison informs eligibility; the policy governs behaviour.

Policy, not a pick

"Which stablecoin is best?" is a point-in-time market judgement (the USDC vs USDT vs DAI comparison answers that). A treasury policy is the durable framework that survives any single asset's changing standing. The recurring failure is treating the pick as the policy — and discovering, during a depeg, that there was no framework at all.

The components

This is an operational governance document, not a market opinion.

Concentration limits: the core control

Single-issuer concentration is the dominant stablecoin treasury risk. A depeg, freeze, or issuer failure hits the whole position if it is all in one stablecoin. Concentration limits — caps per issuer and in aggregate — convert a binary catastrophic exposure into a bounded, survivable one. The limit is the control; which stablecoins is secondary to not over-concentrating in any. This is the diversification discipline as a hard policy rule.

Issuer and reserve due diligence

Test, recurring (not one-off):

• issuer regulatory status — permitted payment stablecoin issuer under GENIUS? MiCA-compliant (EMT/ART)?
• reserve composition/quality — cash & short Treasuries vs riskier assets;
• transparency cadence — monthly disclosure + independent audit, not only a proof-of-reserves dashboard;
• operational controls at the issuer.

Issuer practices and status change — diligence is a cadence, not a checkbox.

The depeg contingency plan

A pre-decided playbook for a held stablecoin losing its peg:

• detection triggers and thresholds;
• who decides;
• actions: rotate, redeem, hedge, halt usage;
• how the event is recorded (the audit trail).

Decide under calm conditions. A treasury without a depeg plan improvises exactly when improvisation is most costly (see stablecoin depeg risk).

Practical guidance

1. Write the policy — eligibility, limits, due diligence, custody, contingency.
2. Make concentration limits hard rules — per issuer and aggregate.
3. Run recurring issuer/reserve due diligence — status changes.
4. Pre-decide the depeg playbook — triggers, decision rights, actions.
5. Keep the policy distinct from the asset pick — the pick feeds eligibility.
6. Record policy adherence in the audit trail; confirm with advisers.

How vendor tools support a stablecoin policy

Cryptio and Request Finance can tag holdings by issuer and surface exposure for limit monitoring. Confirm the tool reports per-issuer and aggregate concentration against policy limits and retains the audit trail — a policy you cannot measure exposure against is unenforced.

How Wag3s helps

Wag3s Ledger tags stablecoin holdings by issuer, reports per-issuer and aggregate concentration against policy limits, and keeps the audit trail of policy adherence and depeg-event handling — so the treasury policy is measurable and enforced, not just written. See the Ledger product page and the Wag3s for accountants page.
