Inflation & Purchasing-Power Loss: What rising prices do to your savings

What inflation means for your savings

Inflation means: prices rise, so over time you can buy less for the same franc. Your savings account balance stays nominally the same – but its purchasing power falls continuously once inflation exceeds the interest you receive on your balance.

What matters therefore is not nominal return but real return: nominal interest rate minus inflation rate. Example: 3 % interest at 2 % inflation gives you only about 1 % real purchasing-power gain. If interest falls below inflation, real return is negative – your savings lose real value even though the account balance looks unchanged.

How it works over time shows the force: at around 2 % annual inflation, CHF 100 of purchasing power is worth only about CHF 82 after ten years; after twenty years about a third of purchasing power is gone. Small percentages compound over decades into tangible amounts – that is the essence of purchasing-power loss.

Switzerland compared: why inflation here remained more moderate

After peaking around 3.5 % in 2022 – the highest level in nearly three decades – Swiss inflation fell rapidly: to 0.2 % in August 2025 and 0.0 % in November 2025 (Consumer Price Index, FSO). By comparison: in the eurozone, inflation climbed to 10.6 % in 2022; in the US to 9.1 %; in the UK to 11.1 %.

The main reason for Switzerland's edge is the strong franc. The national bank deliberately let the franc appreciate from mid-2021 onwards; the euro fell from around 1.06 francs (February 2022) below parity to about 0.95 francs (September 2022). A strong franc cheapens imports – and because roughly two-thirds of imports come from the EU, this substantially dampens imported inflation.

A second, secondary buffer is the energy mix: in 2024, around 89 % of Swiss electricity came from hydro (60.0 %) and nuclear (28.6 %), and end-customer energy prices are typically adjusted only once a year. This dampened the energy-price shock that hit other countries. Important to note: the energy mix is one factor, not the main cause – the strong franc comes first.

Price stability instead of inflation target: the SNB's role

The Swiss National Bank (SNB) has the statutory mandate to ensure price stability. It defines this as consumer-price increases of less than 2 % per year – but it also views deflation (falling prices) as a violation of price stability. In practice, this yields a target band of 0–2 %.

Deliberately, the SNB avoids the term "inflation target" (Inflation Targeting): it does not set a single target value but defends a band in both directions. This is a common misconception – anyone saying the SNB has a "2 % target" confuses the band with a point target.

In its situation assessment of 11 December 2025, the SNB projected inflation of 0.2 % for 2025, 0.3 % for 2026 and 0.6 % for 2027 (conditional forecast at a policy rate of 0 %). Such figures are snapshots and are regularly revised – for your own preparedness, the day's figure matters less than understanding the mechanism.

What really protects against inflation – and what does not

The rule of thumb is: what has a fixed nominal value protects poorly against inflation. Cash loses to purchasing-power erosion, and nominal bonds can even suffer price losses if rates rise – a broad US Treasury bond index lost roughly 13 % in 2022. Both tend to correlate negatively with unexpected inflation.

Real assets are regarded in specialist literature as more effective inflation shields: real estate, equities and commodities have historically correlated positively with unexpected inflation. These are general framings from mainly international, period-dependent studies – not a guarantee and explicitly not a recommendation for any specific product.

What this means for your preparedness

For emergency preparedness, the message is sobering: keeping some cash at home makes sense because if the power fails, ATMs and card readers stop working – then every small note counts. That is crisis preparedness, not inflation protection: against slow currency erosion, hoarded cash does not help at all, quite the opposite.

For beginners: cleanly separate the two questions. Emergency preparedness means water, food, medicines, light, radio and a small cash reserve for realistic emergencies (power outage, supply disruption). Wealth protection against inflation is a separate question of personal financial planning – it belongs in individual advice, not in emergency stock.

Expert tip: always think in real terms for long-term savings. Do not just ask "how much interest will I get?", ask "how much is left after inflation?". Those who think in real returns rather than nominal amounts grasp inflation's silent effect – and make steadier decisions.

Common misconceptions

• "Gold surely protects against inflation" – this is disputed. Over very long periods, some view gold as a store of value, but as a short-term inflation hedge it performed unreliably in studies (a peer-reviewed investigation by Salisu et al. 2020 contradicts the conventional wisdom); specialist literature is divided. "Sure" gold as an inflation hedge is not.
• "My money in savings account is safe" – nominally yes, in real terms no. As long as inflation exceeds the savings-account interest, the balance continuously loses purchasing power even if the amount stays the same.
• "The SNB has a 2 % inflation target" – wrong. The SNB defines price stability as increases below 2 % and also treats deflation as a violation; it is a 0–2 % band, not a point target.
• "Switzerland has practically no inflation" – currently low, but not immune. In 2022, inflation was around 3.5 %, the highest in nearly 30 years. Low figures are not a law of nature.
• Only looking at nominal interest rate – a high rate helps nothing if inflation is even higher. What always matters is real return (interest minus inflation).
• Mistaking a large emergency stock for wealth protection against inflation – a stock bridges supply gaps, but is not an investment and does not shield wealth from currency erosion.
