Your emergency fund has to be safe and available at any time, yet the interest on it is tiny. This guide shows you how to calculate your emergency fund and compares three strategies, plus two further ideas, for getting more out of your cash reserve in Switzerland.
Key takeaways
- The usual rule of thumb is 3 to 6 months of expenses, or 6 to 12 months if you are self-employed. Your own situation matters more than the rule.
- Swiss savings rates average just 0.11% (January 2026), so comparing banks can make a real difference.
- Money market funds and a small “cash-satellite” ETF slice are two ways to add return without putting the core of your reserve at risk.
“How much cash reserve do I actually need, and where is the best place to park it?” I hear this question often.
Everyone should have an emergency fund (in German, a “Notgroschen”), as far as possible. The challenge is that this money must be within easy reach, so it usually sits in a savings account and doesn’t work for you. If you invest it, it can earn returns, but it may not be available immediately, or only at a loss. I’ve looked at several strategies that soften this trade-off.
How Much Emergency Fund Do You Really Need?
According to the Federal Statistical Office (FSO), around 25% of households in the lower middle income bracket cannot easily cover an unexpected expense of CHF 2,500. That is exactly what an emergency fund is for: the broken washing machine, the gap between two jobs, whatever life throws at you.
The common rule of thumb is 3 to 6 months of expenses. If you are self-employed or have an irregular income, aim for 6 to 12 months. That can mean several thousand francs sitting in a savings account, so it’s worth working out the amount you really need rather than just following a rule.
Ask yourself these questions to personalise your number:
- Do I really need 3 to 6 months of expenses? Perhaps your fixed costs plus a small extra would be enough.
- Do I have other protection? If you have loss-of-income insurance that pays out after just 90 days, you may not need 8 months of savings.
- Do I have investments, or people who depend on me? A long-held portfolio in profit can cushion part of the reserve in an emergency, while dependants call for a larger buffer.
Your emergency fund should fit your life and be an amount you feel comfortable with.

Why Your Emergency Fund Loses Value in a Swiss Savings Account
The SNB policy rate is 0%. The average savings account rate in Switzerland was only 0.11% in January 2026 (moneyland.ch). By comparison, the ECB deposit rate is 2.50% and the US federal funds rate is 3.75 to 4.00% (both as of October 2026). Swiss savers simply get far less interest.
The real reason your emergency fund “shrinks” is inflation. The SNB expects 0.6% for 2026. At a savings rate of 0.0%, your balance stays the same, but you can buy less with it.
A foreign currency account is usually not worthwhile for an emergency fund because of exchange rate risk, unless you plan to move abroad in an emergency.
Your reserve must stay available and safe, which limits your options. The goal is the best balance between availability and preserving value. The strategies below are built around that.
Strategy 1: Compare Swiss Savings Account Interest Rates
According to moneyland.ch (January 2026), interest rate differences between Swiss banks are large. On CHF 10,000 in a “typical” savings account you earn roughly CHF 5 a year, while at the Caisse d’Epargne d’Aubonne it was CHF 100 at the time of comparison.
Rates change constantly, so a comparison every few months pays off. Moneyland updates its savings account comparison monthly. The esisuisse deposit guarantee protects up to CHF 100,000 per customer and bank, whether it’s a major bank or a neobank.
Before switching, check the conditions and transaction costs, as offers may be tied to certain amounts or time periods.
Strategy 2: Money Market Funds for Your Emergency Fund
Money market funds invest in short-term, highly secure securities such as time deposits or short-dated bonds from top-rated issuers. That means a much lower price risk than stocks, but still daily access to your money, unlike a bank bond (Kassenobligation). Examples are the UBS (CH) Money Market Fund - CHF P (ISIN CH1242092943) and the Swisscanto CH Investment Fund II (ISIN CH1220495068). You can find a further selection here.
Good to know:
- Money market funds are not covered by the esisuisse deposit guarantee. Legally, fund assets are separate from the custodian bank and remain yours in a bankruptcy, but it is still worth checking the provider’s creditworthiness.
- You need a securities account, and some banks charge extra fees for it.
- Check the fund’s costs before investing.
These funds suit you if you want to park liquidity for an indefinite period without a fixed time horizon.
Strategy 3: The Cash-Satellite Approach
Keep the largest part of your emergency savings (e.g. 90%) liquid in a savings or current account. Put a small part (e.g. 10%), which you could do without if it came to the worst, into a more defensive investment such as a minimum volatility or dividend ETF.
Example: using market data for the iShares Edge MSCI World Minimum Volatility ETF (justETF, as of August 2026), take an emergency fund of CHF 30,000. CHF 27,000 (90%) sits in a savings account at 0.2% interest and CHF 3,000 (10%) in the ETF.
- Positive case (the ETF’s 1-year return of +8.11%): the cash portion earns CHF 54 and the ETF portion roughly CHF 243. That is about CHF 297, or just under 1% on the whole reserve.
- Bad case (calendar year 2022, a real crisis year, with -8.78% for this ETF): the cash portion still earns CHF 54, while the ETF portion loses roughly CHF 263. The net result is a loss of about CHF 209, or -0.7%.
Even in the bad case, most of your reserve stays intact, because only 10% carries any price risk. (Historical values, not a forecast. Past performance is no indicator of future results.)
Your cash portion remains completely untouched. In an emergency you may only need part of the fund and can sit out the satellite. In good years, your emergency fund has the chance to grow more than it would in a savings account alone.
Other Ways to Boost Your Emergency Fund (and Their Drawbacks)
- Bank bond ladder (Kassenobligationen-Treppe): invest in staggered bank bonds with different maturities. There is no price risk, but short maturities currently pay very little, and your money is tied up for the duration.
- Paying taxes in advance: earns credit interest of 0 to 2% depending on the canton (Zug is highest, and several cantons now pay nothing). It only pays off in some cantons, and the money is locked up when you need it.
- Gold: popular as a “crisis currency”, but currently too volatile for an emergency fund. Physical gold or coins also bring storage costs.
I like to keep it simple. I calculated my emergency fund based on what I think I’d need in the worst case, and I review it once a year. 80% sits in a money market fund and 20% in a world ETF.
Emergency Fund FAQ
How much emergency fund should I have in Switzerland?
A common rule is 3 to 6 months of expenses, or 6 to 12 months if you are self-employed or have irregular income. Insurance, investments and dependants can raise or lower your personal number.
Where should I keep my emergency fund?
Mainly in an easily accessible, deposit-protected account. Some savers add a money market fund or a small ETF portion, as long as the core stays liquid and safe.
Is my savings account protected in Switzerland?
Yes. The esisuisse deposit guarantee covers up to CHF 100,000 per customer and bank. Money market funds are not covered by it.
Is it worth switching savings accounts?
Rate differences between Swiss banks can be large, so comparing every few months can pay off. Check conditions and transaction costs first.
Can I invest my emergency fund?
Only a small share you could do without in a worst case, as in the cash-satellite approach. Investments can lose value or be hard to access at short notice.
