In 2022, inflation in Switzerland rose to 3.5 percent. That may sound modest by international comparison, but for a country that had treated price stability as a given for decades, it was a shock. Savers watched their money in bank accounts lose purchasing power. Bonds delivered real losses. And everywhere you heard the same advice: buy real estate. Concrete gold protects against inflation.

But is that really true? The answer, as is often the case with real estate, is more complicated than the slogan suggests. In this article, we analyse the inflation protection thesis point by point, using real data from Switzerland, and distinguish between owner-occupied homes and investment properties. Because for investors, different rules apply than for homeowners.

Why Real Estate Is Considered an Inflation Hedge

The thesis is simple and intuitive: real estate is a tangible asset. When money loses value, prices of tangible goods rise. An apartment in Zurich remains an apartment in Zurich, regardless of what a franc is still worth. This logic rests on three concrete pillars.

Pillar 1: The Tangible Asset Effect

A property consists of land and building. Land is limited, especially in Switzerland, where only around 7 percent of the area is used for settlements. With an increasing money supply and limited supply, prices rise. That is the basic principle of the tangible asset argument.

Historically, Swiss property prices have beaten inflation over long periods. According to the Wuest Partner property price index, residential property prices rose by around 80 percent in real terms (i.e. inflation-adjusted) between 2000 and 2024. That is impressive.

But caution: this figure reflects an exceptional period. Falling interest rates, rising immigration, and tight supply drove prices. Expecting the same development over the next 25 years would be optimistic.

Pillar 2: Rent Adjustments

For landlords, the second pillar is particularly relevant: rents can be adjusted for inflation. In Switzerland, this happens through the reference interest rate and the national consumer price index. When inflation rises, the landlord may increase rents. Income therefore grows with price increases.

The Federal Office for Housing regulates the details: 40 percent of the inflation since the last rent determination may be passed on to the tenant. With cumulative inflation of 5 percent, you may therefore raise the rent by 2 percent (plus any adjustments for reference rate changes and cost increases).

Pillar 3: Debt Erosion

The third and often underestimated effect: inflation erodes debt. If you have a mortgage of CHF 1'000'000 and inflation is 3 percent per year, that debt is only worth around CHF 744'000 in real terms after 10 years. You repay the same nominal amount, but in "cheaper" money.

For highly leveraged investors, this effect can be enormous. With a typical loan-to-value of 75 percent, you benefit from a lever: inflation erodes your debt while the tangible asset (ideally) keeps pace.

Why the Thesis Only Partially Holds

As convincing as the three pillars sound, there are weighty counterarguments in practice. And these are the ones that tend to be overlooked in euphoric times.

Counterargument 1: Rising Interest Rates Eat Into Returns

Inflation rarely comes alone. The central bank responds to rising prices with interest rate hikes. And higher interest rates hit real estate investors doubly:

First, mortgage costs rise. If you took out a SARON mortgage at 0.5 percent in 2021, you were suddenly paying 1.5 to 2 percent in 2023. On a mortgage of CHF 800'000, that means CHF 8'000 to CHF 12'000 more per year. Your cashflow needs to absorb that first.

Second, property prices fall. Higher interest rates mean higher financing costs for buyers. Demand drops, and prices follow. In Switzerland, this effect was visible in 2022/23 for condos and single-family homes, albeit more modestly than in other countries.

With the forecast tool, you can run different interest rate scenarios and immediately see how rising SARON rates affect your cashflow and overall return.

Counterargument 2: Rent Adjustments Lag Behind

Rent adjustment sounds good in theory but works only with a delay in practice. You cannot raise the rent immediately when inflation rises. You must wait for the next termination date, use the official form, and meet the legal requirements.

In Switzerland, a further limitation applies: only 40 percent of inflation can be passed on. With 3 percent inflation, you may add 1.2 percent to the rent. Your costs (mortgage interest, ancillary costs, maintenance), however, may be rising faster.

And then there is the reality of the rental market: in a market with increasing supply (for example in peripheral locations), you cannot actually enforce the theoretically permissible increase because you would otherwise risk vacancy.

Counterargument 3: Construction Costs Rise Too

Inflation drives not only rents but also construction and maintenance costs. Tradespeople become more expensive, material costs rise, renovations cost more. For existing property owners, this means: the real value of your building declines faster if you do not invest continuously. And those investments cost more due to inflation.

The Swiss construction price index rose by around 15 percent between 2020 and 2024. That is significantly more than general inflation over the same period.

Counterargument 4: The Reference Rate as a Brake

The mortgage reference interest rate is a double-edged sword. When interest rates rise, landlords may increase rents if the reference rate rises. But the reference rate moves slowly. It is based on the average of all outstanding mortgages, not on current market rates. This means: your mortgage costs rise quickly, but the permissible rent increase comes with a delay.

Between 2022 and 2024, the reference rate rose from 1.25 to 1.75 percent, an increase of 0.5 percentage points. In the same period, SARON mortgage rates rose by over 1.5 percentage points. The gap between costs and income widened.

Owner-Occupied Home vs. Investment Property: Two Different Worlds

The inflation protection question must be answered differently for homeowners and investors.

For Homeowners

Those who live in their own home benefit from inflation in two ways: debts are eroded, and the tangible asset value tends to rise. At the same time, they save on rising rents. The inflation protection here is relatively strong because the "return" in the form of saved rent does not depend on market fluctuations.

Whether buying or renting is cheaper in your situation depends on many factors. Our buy vs. rent comparison helps you make the decision based on your specific numbers.

For Investors with Investment Properties

For landlords, the situation is more nuanced. Yes, rental income can be adjusted. Yes, debts are eroded. But costs also rise, the reference rate lags behind, and rising interest rates burden cashflow. Inflation protection is not automatic here but depends on the specific financing structure and location.

The decisive question is: how highly leveraged are you? With high leverage (75 percent and more), you benefit strongly from debt erosion but also suffer more from rising interest rates. With low leverage (below 50 percent), the debt erosion effect is smaller, but your cashflow remains stable.

What the Data Actually Shows

Rather than discussing theories, let us look at the facts. What actually happened in Switzerland?

Period 2000 to 2020: Paradise for Property Owners

In these 20 years, the policy rate dropped from over 3 percent to below zero. Property prices rose massively, inflation was minimal (averaging under 0.5 percent per year). Real estate was not an inflation hedge because there was barely any inflation. It was an asset class that benefited from falling interest rates and immigration.

Period 2022 to 2024: The Reality Check

Inflation rose to 3.5 percent, the SNB raised the policy rate from minus 0.75 to 1.75 percent. Condos stagnated or lost slightly in value. Rental properties held up better because rental income could be adjusted. But net yields fell due to rising mortgage costs.

The Lesson

Real estate protects against inflation in the long run, but not in the short run and not automatically. During phases of rising interest rates, property prices can fall even though inflation is high. The inflation protection only shows over a period of 10 to 20 years, as rent adjustments accumulate and debt erosion takes effect.

Strategies for Inflation-Conscious Investors

If you want to hedge against inflation, consider the following points:

1. Take out long-term mortgages. During phases of low interest rates, lock in your financing costs with a 10-year fixed-rate mortgage. If inflation rises afterwards, you benefit from debt erosion while your interest costs remain unchanged.

2. Maintain cashflow reserves. Rising interest rates, rising costs, delayed rent adjustments: all of these burden cashflow. Keep reserves of at least 6 to 12 monthly rents to bridge shortfalls.

3. Implement rent adjustments consistently. Many landlords shy away from the effort of adjusting rents. That is a mistake. If you do not enforce the legally permissible increases, you lose real income over the years.

4. Choose locations with strong demand. Inflation protection only works if demand for your apartments remains high. In peripheral locations with oversupply, you cannot enforce rent increases regardless of what the law allows.

5. Do not forget diversification. Real estate is a good building block, but not the only one. Equities, inflation-protected bonds, and commodities complement the portfolio.

Conclusion: Concrete Gold Shines, But Not Always

Real estate offers a degree of protection against inflation in the long run. The combination of tangible asset value, adjustable rental income, and debt erosion is real and measurable. But this protection is neither automatic nor short-term. Rising interest rates, delayed rent adjustments, and higher construction and maintenance costs can negate the effect in the first years of an inflationary phase.

For Swiss investors, the takeaway is: do not buy property solely for inflation protection. Buy it because the return works, the cashflow is positive, and the location has a future. Inflation protection is then a welcome bonus, not the main argument.

Frequently Asked Questions

Does real estate in Switzerland really protect against inflation?

In the long term, yes. In the short term, not necessarily. Over periods of 10 to 20 years, Swiss real estate has historically beaten inflation. In short-term inflationary phases, however, rising interest rates can put pressure on prices and burden cashflow.

Can I raise the rent as a landlord when there is inflation?

Yes, but only partially and with a delay. Swiss tenancy law allows 40 percent of inflation to be passed on to the rent. Additionally, adjustments for the reference interest rate and increased maintenance costs can be claimed. The increase must be communicated using the official form and within the prescribed deadlines.

Is high leverage advantageous during inflation?

Debt erosion is greater with high leverage because more nominal debt "melts away." However, interest rates also rise during inflation, which increases mortgage costs. The net effect depends heavily on the type of mortgage (fixed vs. SARON) and the timing.

What real estate strategy is best during rising inflation?

The best strategy combines long-term fixed-rate mortgages (to limit interest rate risk), consistent rent adjustments, and strong locations with high demand. Additionally, you should maintain cashflow reserves to absorb temporary cost increases.
