How Much of Your Treasury Should Sit in Yield? A CFO Allocation Framework

The right amount of treasury to place in yield is not a fixed percentage. It depends on when the company needs its money, how predictable its cash flows are and how quickly each yield position can be redeemed.

A practical treasury allocation starts with runway. Keep near-term operating cash immediately available, build a liquidity buffer for delays and unexpected costs, then consider yield only for funds that are not required during those periods.

The key question is not simply, “What return can we earn?” It is, “Will the principal be available in the correct currency, on the correct network and in the company’s bank account or wallet before an obligation is due?”

Start with liquidity terms, not the headline rate

Before allocating funds, classify each yield opportunity by its actual route back to spendable cash. “Liquid” can mean several different things:

“T+1” means one business day after the redemption request. Finance teams should also check cut-off times, weekends, bank holidays, minimum redemption amounts, fees and whether withdrawals can be delayed under exceptional conditions.

For every opportunity, document the source of yield, the assets or counterparties involved, whether the return is fixed or variable, how fees are charged and what could cause a loss of principal. A higher stated rate does not compensate for a mismatch between redemption timing and payroll.

Use a four-bucket runway framework

Bucket 1: Immediate operating cash

This bucket covers obligations that cannot tolerate a redemption delay. It normally includes payroll, taxes, rent, critical suppliers, debt payments and expected card spending.

A useful starting point is one to two months of gross cash outflows, plus known exceptional payments. Use gross outflows rather than net burn when customer receipts are volatile. Incoming revenue does not pay a bill until it has settled and is available to spend.

Keep this bucket in the currencies and locations where payments originate. A company paying EUR payroll through SEPA and USD vendors through ACH or Fedwire should not assume that USDC can always be sold, converted and transferred to both bank accounts at short notice.

Bucket 2: Liquidity buffer

The liquidity buffer covers the next several months of runway and operational disruption. It may be suitable for same-day or T+1 yield, but only where the redemption terms fit the payment schedule.

Size the buffer using stress scenarios rather than averages. Consider:

• One or two delayed customer payments.
• A 20% to 30% increase in monthly expenses.
• Stablecoin conversion, banking or blockchain delays.
• Weekend and public holiday coverage.
• An urgent requirement to move funds to another network or currency.

If four months of expenses equal $3.2 million, a 10% operational cushion would increase the required reserve to $3.52 million. The cushion is a company policy choice, not a universal standard.

Bucket 3: Extended runway

Funds needed later in the runway may be considered for notice-period or fixed-term opportunities. Maturities should be spread across dates rather than concentrated in one position.

For example, if monthly outflows are $800,000, a company could avoid having more than one month of expenses mature on any single date. This creates a ladder: part of the balance becomes available each month as the spending date approaches.

Bucket 4: Strategic surplus

Cash beyond the approved runway can support acquisitions, expansion, debt repayment or shareholder distributions. It may also be eligible for yield, but it is not automatically “spare.” The board-approved capital plan should determine its time horizon.

A worked $12 million treasury example

Consider a company with $12 million across USD and USDC. Gross monthly outflows are $800,000, and management wants at least 12 months of runway. The company has a $400,000 tax payment and a $200,000 annual software renewal due within 60 days.

Under this framework, $2.2 million, or 18.3% of treasury, remains outside yield as immediate operating cash. Up to $9.8 million, or 81.7%, could be evaluated for yield. That is an eligibility ceiling, not a recommendation to invest the full amount.

The finance team might keep part of the liquidity buffer outside yield, exclude balances needed for network fees and decline opportunities that concentrate exposure with one provider or redemption date. After those adjustments, the actual allocation could be materially lower.

Match the allocation to currencies and payment rails

Runway is not fully interchangeable across assets. Separate the forecast by payment currency, stablecoin and network.

• Fiat obligations: Allow time to redeem USDC or USDT, convert it and settle funds through SEPA, ACH, Fedwire, SWIFT, Faster Payments or another required rail.
• Stablecoin obligations: Hold enough on the networks used for payroll, vendors and invoices. Bridging between Ethereum, Base, Arbitrum, Polygon, Tron, BNB Chain, Optimism or Solana adds another step.
• Blockchain fees: Maintain the relevant network token where required to pay transaction fees.
• Restricted balances: Do not count funds as runway if they are reserved, pledged or otherwise unavailable for ordinary expenses.

Stablerail business accounts can hold fiat and USDC or USDT, support on- and off-ramps, and execute payouts across supported banking rails and blockchain networks. Finance teams can review available treasury opportunities and their stated liquidity terms through Stablerail Earn.

Set allocation limits before moving funds

A workable policy should state more than a maximum yield percentage. Define:

• The minimum number of months held as immediate operating cash.
• The minimum liquidity buffer and the stress assumptions behind it.
• Maximum exposure by provider, asset, network and maturity date.
• Which liquidity terms are permitted for each runway bucket.
• Who can approve allocations, redemptions and policy exceptions.
• How often finance will recalculate runway and rebalance.

Monthly review is a reasonable baseline for many companies, with an immediate review after a major financing, acquisition, revenue change or market event. The forecast should use current balances, realistic collection dates and committed expenses.

The decision rule

A simple CFO rule is: only allocate funds to yield when the expected redemption date, plus a stress margin, falls before the date the cash could be needed.

Protect operating cash first. Size the liquidity buffer second. Allocate extended runway in staggered maturities, and treat any headline yield as secondary to principal risk and access. This approach produces a treasury allocation tied to actual obligations rather than an arbitrary percentage.
