Swiss mortgage rates in May 2026

The Swiss National Bank (SNB) kept its policy rate at 0.00 % in the assessment of 19 March 2026, after several cuts during 2025. As a result, the SARON (Swiss Average Rate Overnight) hovers near zero, and fixed-rate mortgages remain attractive.

Fixed-rate mortgages: current benchmarks

Source: indicative rates based on the published schedule of Migros Bank and the comparison by Vermögenszentrum (VZ), as of 28 May 2026. Your personal rate may differ based on creditworthiness, loan-to-value and equity ratio.

SARON mortgages in May 2026

SARON replaced the LIBOR in 2022. It reflects the average interest rate at which banks lend money to each other overnight, and is published daily by SIX. For mortgages, the Compounded SARON over 3 or 6 months is applied.

| SARON component | Range May 2026 | Notes | |-----------------|-----------------|-------| | Compounded SARON 3M | ≈ 0.00 % – 0.05 % | Tracks the SNB policy rate of 0.00 % | | + bank margin | + 0.80 % – 1.50 % | Provider-dependent, often negotiable | | Final SARON rate | 0.80 % – 1.50 % | Adjusted quarterly or semi-annually | | SARON with cap | 1.10 % – 2.00 % | Rate ceiling against surcharge | | Eco / Minergie discount | – 0.10 % – 0.30 % | For certified properties |

SARON or fixed rate? Our reading for 2026

Fixed-rate: planning certainty

A fixed-rate mortgage suits you if you:

• need budget security over multiple years
• want to lock in the current low rate for a longer period
• have neither time nor appetite to monitor the market continuously

Example: 500,000 CHF mortgage, 5-year fixed at 1.50 %. Total interest cost over 5 years: about 37,500 CHF (excluding amortisation and ancillary costs).

SARON: low-cost but mobile

SARON mortgages are significantly cheaper than 5-year fixed mortgages in May 2026. Advantage: real savings. Disadvantage: the bill can rise if the SNB tightens.

• Flexibility: typically 3 to 6 months' notice for termination
• Adjustment: rate revised every 3 or 6 months
• Risk: an increase in the SNB policy rate flows through to your monthly payment

Example: 500,000 CHF mortgage at 1.10 % SARON. Interest cost over 5 years at stable SARON: about 27,500 CHF, roughly 10,000 CHF less than the fixed example above. The saving is real but not guaranteed.

Which profile for which model?

| Profile | Recommended mortgage | Reason | |---------|----------------------|--------| | Family with fixed budget | Fixed 5 – 10 years | Planable instalments, no surprises | | Dual-income with reserves | SARON | Rate savings exploitable, fluctuations manageable | | Approaching retirement | Fixed 10 years | No rate risk during retirement | | Yield property with strong affordability | Split SARON + fixed | Savings combined with security |

Affordability: how much can you borrow?

Affordability rules stem from the self-regulation directive of the Swiss Bankers Association (SBA), recognised by FINMA as a minimum standard (FINMA Circulars).

The three core rules

1. Imputed rate of 5 % – banks calculate affordability with a prudent stress rate, not the market rate.
2. One-third rule – interest (at 5 %), amortisation and ancillary costs (1 % of market value) combined must not exceed one-third of gross income.
3. Maximum loan-to-value of 80 % – up to 80 % of the property value can be financed. For owner-occupied homes, the 2nd mortgage (the share above 66.67 %) must be amortised within 15 years or by the standard AHV / OASI retirement age.

Worked example

Assumption: single-family home at 1,000,000 CHF, equity 200,000 CHF, mortgage 800,000 CHF, gross income 150,000 CHF.

| Item | Calculation | Annual amount | |------|-------------|----------------| | Imputed interest (5 %) | 800,000 × 5 % | 40,000 CHF | | 2nd-mortgage amortisation | (800,000 − 666,667) ÷ 15 | 8,889 CHF | | Ancillary costs (1 % of market value) | 1,000,000 × 1 % | 10,000 CHF | | Total burden | | 58,889 CHF | | Affordability threshold (1/3 of income) | 150,000 ÷ 3 | 50,000 CHF | | Result | 58,889 > 50,000 | not affordable |

In this example you would need to bring more equity or choose a smaller property. To run your own numbers without commitment, use the Moneyland mortgage calculator.

Equity: 20 % minimum

To buy a Swiss property, you must contribute at least 20 % equity. At least 10 % must be "hard" equity that does not come from pillar 2 (pension fund).

What counts as equity?

| Source | Hard or soft | Notes | |--------|---------------|-------| | Savings, securities | Hard | No restriction | | Gift, advance inheritance | Hard | Written agreement recommended | | Pillar 3a | Hard | Withdrawal or pledging possible | | Pension fund (pillar 2) | Soft | Maximum 10 % of acquisition value | | Insurance policies | Hard (surrender value) | Check tax implications |

A pillar 2 withdrawal reduces your future pension. A pledge keeps the capital invested but increases your mortgage costs. The right choice depends on age, family situation and pension strategy.

Before any pillar 2 withdrawal, compare the tax consequences – they vary significantly by canton.

Refinancing in 2026: when switching pays

A refinancing is worthwhile when all three conditions are met:

• Your existing mortgage expires within 12 to 18 months
• The market rate is at least 0.30 % – 0.50 % below your contract rate
• Your loan-to-value is 65 % or less (no amortisation pressure)

Example: refinancing 500,000 CHF

| Item | Old mortgage | New mortgage | Difference | |------|--------------|---------------|------------| | Mortgage amount | 500,000 CHF | 500,000 CHF | – | | Term (new) | – | 5 years | – | | Rate | 2.00 % | 1.50 % | – 0.50 pp | | Interest 5 years | 50,000 CHF | 37,500 CHF | − 12,500 CHF |

The 12,500 CHF saving only applies if you switch on schedule. Early termination triggers a prepayment penalty that often wipes out the advantage.

Three-phase plan

Phase 1 – Preparation (4 to 6 weeks)

1. Gather the existing mortgage contract and valuation documents
2. Have the market value re-assessed if the property was renovated or extended
3. Engage an independent adviser or mortgage platform

Phase 2 – Comparison and negotiation (2 to 3 weeks)

1. Obtain 3 to 5 quotes (bank, cantonal bank, insurer, online)
2. Calculate the effective rate: interest + processing fees + appraisal fees
3. Use the best offer to negotiate with your incumbent bank

Phase 3 – Conclusion (2 to 4 weeks)

1. Sign the new credit contract
2. Notify the land registry of the change
3. Terminate the old mortgage within the notice period, coordinate the disbursement

Common mistakes – and how to avoid them

Mistake 1: focusing only on the nominal rate

The nominal rate is only part of the story. The effective rate also includes:

• Appraisal and processing fees (typically 1,500 – 3,000 CHF one-off)
• Bank margin (negotiable, up to 0.20 pp leeway)
• Pledging costs for pillar 3a-backed solutions

Mistake 2: too short a term

A 2-year fixed mortgage looks attractive but can become a trap if rates rise. Without a strong market view, a 5- or 7-year fixed mortgage offers a historically balanced compromise.

Mistake 3: underestimating amortisation

The 2nd mortgage (share above 66.67 % of market value) must be amortised within 15 years or by AHV / OASI retirement age. Neglecting it can trigger a rectification obligation if the property loses value.

Mistake 4: ignoring imputed rental value

In Switzerland, owner-occupied property is still taxed on its imputed rental value (Federal Tax Administration). Mortgage interest and maintenance are deductible in return. A political reform is in progress in 2026 but not yet decided.

Mistake 5: skipping advice

A one-off meeting with an independent adviser typically costs 300 – 800 CHF and can save four to five figures over the mortgage's life. Affiliate platforms often offer free advice – check whether the adviser earns commissions that may influence the recommendation.

2026 trends to track

Digital mortgages become standard

Platforms such as key4 (UBS), Moneypark, HypoPlus and finovo aggregate offers from multiple banks. The contract remains in writing, but the comparison step is much faster.

Green mortgages deliver measurable benefits

Banks reward energy-renovated properties:

• Migros Bank Eco mortgage: up to 0.15 % discount on the standard rate for Minergie-certified buildings
• Raiffeisen mortgage with GEAK class A/B: comparable discount
• PostFinance renovation mortgage: special terms for energy upgrades

Imputed rental value reform

In autumn 2025, parliament forwarded a bill to abolish the imputed rental value (business 24.073). A popular vote is likely, with no decision yet in 2026. Current rules remain in force.

Checklist: step by step

Before the search

• [ ] Estimate affordability (5 % imputed rate)
• [ ] Have the market value of the property assessed
• [ ] Gather equity (at least 20 %, of which 10 % hard)
• [ ] Budget around 5 % of the purchase price for ancillary costs (notary, land register, cantonal transfer tax)

During comparison

• [ ] Obtain at least 3 to 5 quotes
• [ ] Compare nominal and effective rates
• [ ] Examine flexibility (cancellation, cap, split, eco discount)
• [ ] For SARON: document adjustment frequency and margin

When signing

• [ ] Read the contract in detail, ideally with a second pair of eyes
• [ ] List every fee (appraisal, processing, intermediation)
• [ ] Confirm building insurance (mandatory in most cantons)
• [ ] Coordinate the land registry filing

After signing

• [ ] Schedule an annual review (reminder 12 months before expiry)
• [ ] Stick to the amortisation plan and analyse tax effects
• [ ] Discuss any energy renovations with the bank – special terms often apply

Conclusion: low rates, intact homework

The 2026 rate environment is unusually favourable for borrowers. Buying or refinancing today means benefiting from an SNB policy rate of 0.00 % and correspondingly low conditions. Affordability, equity and the SARON-vs-fixed choice nevertheless remain demanding decisions – with effects spanning 10 to 30 years.

Compare at least 3 to 5 providers, watch the imputed-rental-value and eco-mortgage developments, and seek an independent second opinion for larger volumes.
