Choosing the right mortgage structure is one of the most important financial decisions when buying property in Switzerland.

In 2026, most Swiss buyers compare two primary financing options:

• Fixed mortgages
• SARON mortgages

Each option offers different advantages depending on market conditions, financial goals, and risk tolerance.

What Is a Fixed Mortgage?

A fixed mortgage locks in an interest rate for a defined period, typically:

• 2 years
• 5 years
• 10 years
• 15 years

This means your mortgage payments remain predictable throughout the term.

Benefits of Fixed Mortgages

• Payment stability
• Easier financial planning
• Protection against rising interest rates
• Popular among families and long-term owners

Potential Downsides

• Less flexibility
• Possible penalties for early exit
• Higher rates during certain market cycles

What Is a SARON Mortgage?

SARON stands for:
Swiss Average Rate Overnight

It is a market-based floating interest rate used widely across the Swiss banking system.

SARON mortgages usually adjust every few months depending on market conditions.

Benefits of SARON Mortgages

• Often lower starting rates
• Greater flexibility
• Attractive during stable or falling interest rate periods

Risks

• Payments may increase if rates rise
• Less predictable monthly costs
• Higher exposure to market volatility

Example Mortgage Comparison

Property Price: CHF 2,000,000
Mortgage Amount: CHF 1,600,000

Example Fixed Mortgage Rate:

2.20%

Example SARON Mortgage Rate:

1.75%

Potential annual difference:

$1,600,000\times (0.022-0.0175)=7,200$

Estimated annual savings with SARON:
CHF 7,200

However, SARON rates may rise over time.

Which Mortgage Is Better in 2026?

The right mortgage depends on your priorities.

Fixed Mortgages Are Better For:

• Families seeking stability
• Long-term homeowners
• Buyers worried about rising rates
• Predictable budgeting

SARON Mortgages Are Better For:

• Flexible investors
• Sophisticated buyers
• Shorter-term ownership strategies
• Buyers comfortable with market fluctuations

What Are Swiss Banks Recommending?

Many Swiss banks currently recommend combining strategies.

For example:

• Part fixed mortgage
• Part SARON exposure

This creates balance between:

• Stability
• Flexibility
• Risk management

Foreign Buyers & Mortgage Strategy

International buyers purchasing Swiss property should also consider:

• Currency exposure
• International income structures
• Residency plans
• Long-term holding strategy

Mortgage advice should always align with broader wealth planning goals.

• Zug
• Zurich
• Geneva

These markets continue to attract both local and international investors.

Final Thoughts

Both Fixed and SARON mortgages remain strong financing options in Switzerland.

The best solution depends on:

• Your financial profile

Careful planning and professional guidance are essential before selecting a mortgage structure.
