Answer capsule. Treasury management is the discipline of holding and moving a company's cash and near-cash assets so it can pay bills, absorb shocks, earn a reasonable return on idle balances, and manage counterparty and currency risk. For a company that holds stablecoins, the mechanics shift: settlement runs 24/7 across chains rather than through bank cutoff windows, custody splits between self-custody and regulated venues, and yield options widen to include on-chain money markets alongside traditional sweep accounts and Treasury bills.

This guide covers what treasury management means in a traditional finance context, how it changes when a company holds stablecoins, when a bank still belongs in the stack, and a worked example splitting a $10M Series B SaaS treasury across traditional and onchain-native allocations.

Answer capsule. Treasury management spans four jobs: keeping enough liquidity to meet payroll and vendor obligations, earning yield on idle balances, managing foreign-exchange exposure when revenue and costs span currencies, and limiting counterparty risk from any single bank, broker, or custodian holding the money.

Liquidity management means projecting inflows and outflows across the next few weeks and quarters so the operating account never runs dry and idle cash never sits at zero yield longer than necessary. Yield management means placing balances not needed this week into instruments that pay something, typically sweep accounts, money market funds, or short-dated Treasury bills. FX management applies when a US company pays a European contractor in euros or collects revenue from Asia, and matters because currency moves can eat margin faster than product costs. Counterparty risk management is the discipline of not holding more with any one bank than FDIC insurance covers (US limit is $250,000 per depositor per bank per ownership category, per FDIC), which is why enterprise treasurers spread balances across multiple banks and money funds.

Answer capsule. The classic corporate treasury sits on operating deposits at one or two banks, sweep or money market balances for near-cash yield, short-dated US Treasury bills for the middle tenor, and FX hedges when currency exposure runs large enough to hurt.

Operating deposits handle payroll, AP, and expense card float. Sweep programs automatically move balances above a threshold into a money market fund each night; the return sits close to the Federal Reserve's target range, less the fund's expense ratio (see the Federal Reserve's overnight rate page). Direct T-bill purchases through TreasuryDirect or a broker capture the same yield without the fund fee, at the cost of manual laddering. FX exposure, when material, is hedged through forwards or options at a rate a corporate FX desk quotes; small companies often accept the exposure rather than pay hedge costs.

Answer capsule. A stablecoin balance settles in seconds across chains, is available on weekends and holidays, sits in self-custody or with a regulated custodian rather than a bank, and can earn yield from onchain money markets whose rates float with borrow demand rather than a central bank target.

The most obvious shift is settlement timing. A bank wire in the US clears through Fedwire or CHIPS within business hours; ACH runs on batch cycles; SWIFT correspondent chains take one to three business days across borders. A USDC transfer confirms in seconds on any chain the counterparty accepts, at any hour. For a company paying international contractors, closing an acquisition on a weekend, or funding a subsidiary that missed a wire cutoff, the round-the-clock property changes what treasury operations can promise the business.

The custody model also changes. Traditional operating cash sits at a bank under FDIC coverage up to $250,000 per depositor per bank per ownership category. Stablecoin balances sit either in self-custody (the company controls keys, via a multisig or MPC wallet) or with a regulated custodian (Fireblocks, Anchorage, Coinbase Custody). Neither carries FDIC coverage; the risk model swaps counterparty bank failure for private-key management and issuer solvency. USDC's issuer, Circle, publishes monthly attestations of its reserves at Deloitte's audit page for public review, and Tether publishes quarterly attestations. Reading these matters the way reading a money market fund's holdings mattered in 2008.

Multi-chain custody adds a new axis. A traditional treasury holds dollars in USD-denominated accounts, full stop. An onchain treasury may hold USDC on Base for one counterparty, USDT on Tron for another, and PYUSD on Ethereum for a third, because that is where each counterparty settles. Managing balances across chains, and moving value between them without paying bridge costs that eat the yield, is a workflow traditional finance does not have.

Yield options widen. On-chain money markets like Aave and Compound let stablecoin holders supply USDC or USDT and earn a variable rate driven by borrow demand on that chain (see the Aave analytics page for current rates by market). The rate is not linked to a central bank target; it moves with leverage cycles. This is a different risk than a money market fund holding Treasury bills, and the yield reflects that.

Answer capsule. A traditional bank still belongs in the stack for payroll to US employees, for vendors that only accept ACH or wire, for FDIC-insured deposit safety on operating cash, and for card programs and credit facilities that no onchain equivalent covers.

Payroll is the clearest case. US employees expect direct deposit through ACH, which requires a bank account on the paying side. Card issuance for employee expenses runs through bank sponsors under Reg II (which caps debit interchange at $0.22 plus 0.05% of the transaction per the Federal Reserve). Credit facilities, from revolving lines to venture debt, sit on bank balance sheets. And operating cash inside FDIC limits carries a guarantee no self-custodied wallet provides.

The pattern for a company holding stablecoins is to narrow the bank rather than replace it. Keep enough at the bank to cover payroll, vendor ACH, and FDIC-insured operating buffer; hold the rest onchain where it settles faster and earns a different mix of yield.

Answer capsule. A hypothetical Series B SaaS with $10M in treasury and international revenue can split its balances across an operating bank buffer, a short-dated Treasury allocation for yield, and an onchain stablecoin allocation for international settlement and additional yield. The illustrative split below shows one reasonable allocation; the actual mix depends on burn, currency exposure, and board risk tolerance.

Assume the company burns $600K per month, collects 40% of revenue in non-USD, and pays 25% of vendors internationally.

The onchain-native allocation buys two properties bank rails do not offer: 24/7 settlement for international AP, and a second yield stream uncorrelated with the Federal Reserve target. Rates on onchain money markets change quickly, and the company should treat the yield as opportunistic rather than budgeted, per the same discipline a treasurer applies to any variable-rate instrument.

Cross-chain movement matters here. If the company holds USDC on Base but a European contractor accepts USDT on Ethereum, a routing layer like Eco selects the path (bridge and swap where required) and returns a confirmation the treasury team can log. That removes the branching logic from treasury operations and turns "which chain does the payment sit on" into a routing question rather than a policy question.

Answer capsule. Treat onchain balances the way a treasurer treats any new instrument class: size the allocation to the operational job it does, cap the concentration to any single stablecoin issuer or chain, and monitor issuer attestations and chain-level risk the way you monitor bank counterparty risk.

Concentration limits apply at the issuer level (USDC versus USDT versus PYUSD versus USDS), at the chain level (Ethereum versus Base versus Solana), and at the custodian level (self-custody multisig versus regulated custodian). A common posture is no more than 50% of the onchain allocation with any single issuer, no more than 60% on any single chain, and a policy on which custodian holds signing keys. These numbers are illustrative; each treasurer sets them based on the board's risk appetite.

Is stablecoin treasury management legal for US companies?

US companies can hold stablecoins as treasury assets subject to accounting, tax, and disclosure rules that continue to evolve; the SEC, IRS, and state regulators have issued guidance and, in some cases, enforcement positions on custody and reporting. Companies typically hold stablecoins through regulated custodians or self-custody wallets under a documented policy reviewed by counsel.

Do stablecoin balances count as cash on the balance sheet?

Under current US GAAP guidance, stablecoin holdings are generally accounted for as intangible assets or under FASB's crypto asset guidance (ASU 2023-08 for entities that hold crypto meeting the scope), not as cash equivalents. Companies should confirm treatment with their auditor.

What is the risk difference between USDC and USDT?

USDC is issued by Circle, a US-regulated stablecoin issuer that publishes monthly reserve attestations. USDT is issued by Tether Ltd., which publishes quarterly attestations. Reserve composition, jurisdiction of issuance, and audit cadence differ; treasurers should read both attestations before setting exposure limits.

How is yield on onchain money markets different from a bank sweep?

A bank sweep pays a rate tied (loosely) to the Federal Reserve's overnight target, reduced by the fund's expense ratio. Onchain money markets like Aave pay a rate driven by borrow demand on that chain, which floats with leverage cycles and can spike or collapse quickly. The yield is not "safer" or "riskier" in the abstract; it is a different exposure with a different driver.

Content in this guide draws on public regulatory sources (Federal Reserve, FDIC, SEC, FASB), issuer disclosures (Circle, Tether), and published rate mechanics for onchain money markets (Aave, Compound). Numeric examples are illustrative and do not represent a specific company; rates and allocations move with market conditions.
