Swiss National Bank Keeps Policy Rate at Zero

Zero remains the SNB's answer to subdued inflation and moderate growth. The Swiss National Bank left its policy rate unchanged at 0%, a decision that keeps Switzerland apart from major economies where borrowing costs have moved higher.

Consumer prices increased by 0.8% in August 2026, their fastest annual rise in two years. The figure remains comfortably within the SNB's definition of price stability, which allows inflation between 0% and 2%. The bank expects the rate to climb to 1.2% in the fourth quarter, largely because of higher oil prices, before easing during 2027.

The decision had been fully anticipated. Economists surveyed by AWP unanimously predicted no change, giving households, companies and financial markets little reason to adjust their immediate expectations.

The SNB's latest projections put average annual inflation between 0.7% and 0.8% from 2026 through 2028, with inflation reaching as much as 0.9% in 2029. Those figures support the bank's assessment that current policy remains consistent with price stability while offering support to an economy facing external uncertainty.

The SNB sees inflation rising temporarily, not breaking loose. Higher oil prices account for much of the near term pressure, making energy costs the principal reason for the expected move to 1.2% inflation late in 2026.

That distinction matters for monetary policy. A rate increase can cool domestic demand, mortgage borrowing and business investment. It cannot directly produce more crude oil or lower the international price of petrol, diesel and heating oil. Tightening in response to a temporary energy shock could therefore weaken Swiss activity without removing the original source of the pressure.

The bank expects annual inflation to remain restrained at 0.7% to 0.8% through 2028, followed by a forecast of up to 0.9% in 2029. The path leaves considerable room before prices approach the upper edge of the SNB's stability range.

The central bank has also raised its assessment of economic growth. It now expects GDP to expand by 1.5% to 2% in 2026, compared with roughly 1% previously, and by around 1.5% in 2027. Demand from abroad, monetary conditions and a weaker Swiss franc should provide support, although the outlook remains exposed to developments beyond Switzerland's borders.

Switzerland's growth outlook has improved, but the risks remain international. The SNB expects foreign demand to help Swiss exporters over the coming quarters, with the franc's depreciation and current monetary conditions adding some stimulus to the domestic economy.

The bank remains ready to intervene in foreign exchange markets if necessary. Its latest language suggests less urgency than in its previous assessment, however, a sign that officials currently see fewer immediate reasons to act against currency movements.

Several threats sit outside the SNB's direct control. A further deterioration in the Middle East could weaken global activity and push energy prices higher. Trade policy could reduce demand for Swiss goods, while exchange rate movements could alter the competitiveness of manufacturers, tourism operators and exporters in cantons from Zurich to Geneva.

The policy decision also highlights Switzerland's divergence from other major central banks. The European Central Bank raised rates earlier in September, while the US Federal Reserve also increased borrowing costs and indicated that additional tightening could follow. Switzerland's lower inflation and smaller domestic demand pressures give the SNB more flexibility to keep rates at zero.

Swiss public finances paid only 0.25% of GDP in government interest during 2025. That was the lowest burden among 35 economies in Econorama's comparison, based on OECD Economic Outlook data.

Luxembourg followed at 0.33%, Ireland at 0.46% and Germany at 1.11%. Italy paid 3.86%, while the United States spent 4.72% of GDP, almost 19 times Switzerland's share. The measure covers gross interest payments by central, regional and local governments as well as social security funds. It does not subtract interest income from public assets.

Switzerland benefits from two reinforcing advantages: relatively low public debt and inexpensive financing. A zero SNB policy rate does not determine every bond yield, but it helps keep the country's borrowing environment favourable. The result gives the federal government and the cantons more room to plan spending on infrastructure, defence, pensions or tax policy.

The comparison also shows why refinancing costs matter. When governments carry heavy debt loads, higher rates increase the share of revenue devoted to servicing earlier borrowing. Switzerland enters that environment with a lighter burden than most peers, leaving its public finances less exposed if global borrowing costs stay elevated.

The zero rate gives Swiss borrowers and public authorities breathing room, while keeping the SNB's next moves dependent on incoming data. For households, the immediate effect is a continued low rate environment for mortgages and savings, although commercial banks set their own lending and deposit conditions.

Businesses also retain access to comparatively cheap financing as they assess investment and export demand. The benefit is most relevant for companies with variable rate debt or loans that need refinancing. Savers, by contrast, continue to face limited returns on cash deposits when inflation remains positive.

For the SNB, the task is to balance those effects against the franc, energy prices and international policy shifts. The bank expects inflation to remain below 1% in much of its forecast horizon, but it has kept foreign exchange intervention available if currency conditions threaten price stability or economic activity.

The policy rate is therefore likely to remain data dependent. The next pressure points are clear: the path of oil prices, the strength of foreign demand, the Middle East situation, trade policy and the franc's exchange rate. For now, the SNB judges that Switzerland's economy can absorb those risks without higher official borrowing costs.
