Why excess liquidity deserves attention
Many Swiss SMEs accumulate bank balances over the course of the year that exceed their actual operating needs: early receipts, seasonal sales, financing not yet invested, or simply prudent cash flow management. Leaving these amounts in a current account earning zero or near-zero interest means accepting a silent opportunity cost, especially in a positive-rate environment.
At the same time, deploying «excess» liquidity is not the same as speculating. The goal of corporate treasury is to preserve capital, maintain rapid access to funds for payroll, VAT, planned investments, and contingencies, and generate a modest but predictable return. The threshold for «excess» varies by sector and seasonality: many companies first define an operating buffer (typically 1–3 months of fixed costs) and consider only amounts above that cushion as investable.
This guide outlines the short-term instruments best suited to SMEs in Switzerland, the risks to assess before investing, and the accounting and tax rules for compliant recording under the Swiss Code of Obligations and Swiss accounting standards (Swiss GAAP FER / micro-GAAP derogation).
Short-term instruments for Swiss SMEs
The choice depends on time horizon, amount, risk tolerance, and statutory constraints. Here is a concise comparison of the main vehicles accessible to small and medium-sized enterprises:
| Instrument | Typical horizon | Liquidity | Expected return | Complexity |
|---|---|---|---|---|
| Savings account / demand deposit | Unlimited | Immediate | Low | Minimal |
| Fixed-term deposit (Festgeld) | 1–12 months | At maturity (penalties possible) | Moderate | Low |
| Money market fund (CHF) | Short (T+1 / T+2) | High | Moderate | Medium |
| Short cantonal / federal bonds | < 3 years | Secondary market (variable) | Moderate | Medium–high |
| Structured / capital-protected products | Variable | Limited or conditional | Variable | High — not recommended for treasury |
For most SMEs, the most balanced combination remains a corporate savings account for the operating buffer and laddered fixed-term deposits for excess amounts with maturities aligned to quarterly VAT payments, tax instalments, or planned investments. CHF money market funds can be useful above higher thresholds (often CHF 100,000+), where net return justifies management costs and due diligence on the fund's prospectus.
Risks to assess before investing
Even instruments considered «safe» carry risks that an SME cannot ignore, especially if liquidity is also needed to cover short-term liabilities:
Liquidity risk
A locked fixed-term deposit is not available until maturity. Early withdrawal may incur penalties or loss of interest. Before locking up funds, map certain outflows over the next 6–12 months: payroll, AHV/occupational pension (AVS/LPP), rent, strategic suppliers, income tax instalments, and VAT.
Counterparty risk
In Switzerland, bank deposits benefit from deposit protection (currently CHF 100,000 per institution and per depositor). Amounts above this should be diversified across several banks or invested in cantonal/federal debt securities with a solvent issuer. Verify the intermediary's rating and balance sheet strength.
Interest rate and price risk
Fixed-rate bonds lose market value if rates rise; for an SME intending to hold to maturity, the accounting effect depends on the valuation method adopted. Money market funds and variable deposits follow market rate movements with lower capital volatility.
Currency and governance risk
Investing liquidity in foreign currency exposes the company to EUR/USD fluctuations. Also verify the articles of association and internal resolutions: some GmbHs or AGs require general meeting approval for investments exceeding an equity threshold or falling outside the corporate purpose. Document the decision and the mandate to management or the board of directors.
Compliant accounting in Switzerland
Under the Swiss Code of Obligations (Art. 958 et seq.) and Swiss accounting standards, short-term investments generally fall within current assets, unless the company intends to hold them beyond 12 months — in which case they may be classified as non-current assets as securities or other long-term financial investments.
The most relevant accounting distinction for treasury is between cash and cash equivalents (bank accounts, cash on hand) and current financial assets (fixed-term deposits, short-term debt securities, money market fund units). Both appear in current assets, but transparent presentation in the balance sheet and notes helps auditors, banks, and business partners understand how much capital is immediately available.
| Transaction | Typical accounting entry (Swiss GAAP FER) | Note |
|---|---|---|
| Purchase of fixed-term deposit | Debit: Fixed-term deposits / Credit: Bank | Classified under current assets |
| Interest accrual | Debit: Amounts due from banks / Credit: Financial income | Accrual basis at year-end if accrued |
| Purchase of short-term debt security | Debit: Securities / Credit: Bank | Valuation at acquisition cost, at market value if observable, or at the lower of cost and net realisable value (Art. 960a–960b CO; FER 2 where applicable) |
| Required write-down | Debit: Securities write-downs / Credit: Securities | Prudence requirement if net realisable value is below cost |
| Withholding tax deducted | Debit: Recoverable withholding tax / Credit: Bank | Recoverable tax credit via Form 25 (FTA) |
SMEs applying the micro-GAAP derogation (Art. 961a CO) may simplify recognition, but remain subject to the prudence principle and true and fair presentation. Interest income must be recorded in the income statement as financial income and is included in taxable profit. Document each position with bank statements, deposit certificates, or fund reports, and reconcile accounting balances with intermediary statements on a regular basis.
Tax aspects and withholding tax
Interest on Swiss deposits and debt securities is subject to 35% withholding tax deducted at source (Withholding Tax Act, LIPrev). Legal entities domiciled in Switzerland may claim a full refund from the Federal Tax Administration (FTA) using Form 25, provided the income has been correctly recorded in taxable profit. Interest and balances on foreign accounts must be declared in the tax return (annual statements and cantonal schedules): income is included in taxable profit and assets are valued at year-end. Automatic exchange of information (AEOI/CRS) makes foreign account holdings traceable; any foreign withholding may be recovered through a global tax reconciliation claim (Form DA-1).
Capital gains on securities held for treasury purposes (early sale of a cantonal bond, for example) are included in taxable profit under Art. 58 of the Direct Federal Tax Act (LIFD). Corresponding capital losses are deductible if correctly recorded in the income statement. Proper accounting of financial investments affects the calculation of taxable profit (federal, cantonal, and municipal income tax) and, where applicable, capital tax determined by the canton of domicile.
At federal level, stamp duty may apply to certain securities transactions; cantons also levy stamp duties on banking documents (account opening, statements, mandates). Consult your cantonal tax adviser if you operate with material amounts or instruments traded outside the bank.
Recommended operational process
A structured approach reduces accounting errors and ensures liquidity remains available when needed:
- Define the operating buffer — calculate the minimum liquidity required (e.g. 60–90 days of operating costs) and keep it in a demand or instant-access savings account.
- Project cash flow — use a quarterly treasury budget to identify temporary surpluses and the acceptable lock-up period.
- Ladder maturities — split excess amounts across several fixed-term deposits with different maturities (e.g. 3, 6, and 9 months) to reduce liquidity risk.
- Document resolutions — record in management or general meeting minutes the authorisation to invest and the limits on amount and duration.
- Record and reconcile — post each transaction to the correct account, accrue interest on an accrual basis, and reconcile monthly with statements.
- Review at each closing — assess whether current/non-current classification is still correct and apply write-downs if net realisable value is below cost.
Compliance checklist
- ✓Operating buffer separated from short-term invested amounts
- ✓Correct balance sheet classification (current vs. non-current assets)
- ✓Prudent year-end valuation (cost or market value, if lower)
- ✓Interest accrued on an accrual basis in the financial income account
- ✓Withholding tax recorded as a recoverable credit
- ✓Documentation archived (contracts, certificates, statements, resolutions)
- ✓Periodic bank reconciliation of investment positions
- ✓Complete tax return disclosure of all investment income
Conclusion
Excess liquidity is not a problem to solve in haste, but an opportunity to manage with discipline. For a Swiss SME, laddered fixed-term deposits and corporate savings accounts remain the most balanced instruments between return, accounting simplicity, and access to funds. More complex instruments — money market funds, traded bonds, structured products — require additional expertise and careful assessment of liquidity and valuation risks.
Accounting software such as Accountex makes tracking easier: automatic classification of treasury transactions, bank reconciliation, accrual of interest income, and preparation of data for year-end closing and the tax return. Investing excess liquidity only makes sense if every franc remains visible, properly accounted for, and recoverable when the company needs it.
