Swiss National Bank: Definition, Mandate, and Role in the Swiss Economy

Definition

The Swiss National Bank (SNB; German: Schweizerische Nationalbank; French: Banque nationale suisse) is Switzerland’s central bank, responsible for the country’s monetary policy, the issuance of the Swiss franc, and the management of foreign currency reserves. Established by the National Bank Act of 1905 and commencing operations in 1907, the SNB is an independent institution operating under a federal mandate to ensure price stability while taking due account of economic developments. It is headquartered in Bern with a second seat in Zurich.

Legal Mandate

The SNB’s mandate is defined in the Federal Constitution (Article 99) and the National Bank Act:

Price stability: the primary objective, defined in practice as annual inflation of below 2 per cent as measured by the Consumer Price Index
Due account of economic developments: the SNB considers the state of the economy — growth, employment, financial stability — when formulating policy, though price stability takes precedence
Currency issuance: the SNB holds the exclusive right to issue Swiss franc banknotes
Financial system stability: the SNB monitors and contributes to the stability of the Swiss financial system, including the oversight of systemically important financial market infrastructures

The mandate’s emphasis on price stability rather than dual mandates (price stability and full employment, as with the US Federal Reserve) reflects Switzerland’s historical prioritisation of monetary discipline.

Governance

Governing Board

The SNB is led by a three-member Governing Board, appointed by the Federal Council for six-year renewable terms. The Board comprises the Chairman, Vice Chairman, and a third member, each of whom manages one of the SNB’s three departments. The compact governance structure — among the smallest of any major central bank — facilitates decisive policy-making.

Independence

The SNB operates with a high degree of independence from political interference. The National Bank Act prohibits the Governing Board from seeking or accepting instructions from the Federal Council, Parliament, or any other body. This institutional independence is a critical pillar of the SNB’s credibility and, by extension, the Swiss franc’s safe-haven status.

Bank Council

The Bank Council — a 11-member supervisory body appointed by the Federal Council and SNB shareholders — oversees the SNB’s administration and governance but does not participate in monetary policy decisions.

Ownership

The SNB is an unusual central bank in that it is partly privately owned. Its shares are listed on the SIX Swiss Exchange, with approximately 55 per cent held by Swiss cantons and cantonal banks, and the remainder held by private shareholders. The federal government holds no shares. The share price is notable primarily as a curiosity: the SNB’s dividend is capped, and shareholders have no influence over monetary policy.

Monetary Policy Tools

Policy Interest Rate

The SNB’s primary policy instrument is the SNB policy rate, which sets the target for secured overnight money market rates. Adjustments to the policy rate influence broader interest rates, credit conditions, and the exchange rate.

The SNB held its policy rate in negative territory (-0.75 per cent) from 2015 to 2022 — a historically unprecedented period of negative rates aimed at reducing the attractiveness of franc-denominated assets and moderating the currency’s appreciation. Rates were raised to positive territory in 2022, reaching 1.75 per cent in 2023, before the SNB began easing in 2024 as Swiss inflation returned to comfortable levels.

Foreign Exchange Interventions

The SNB has historically used foreign exchange market interventions — buying foreign currencies and selling Swiss francs — to moderate franc appreciation. These interventions reached extraordinary scale following the 2011-2015 EUR/CHF floor policy, during which the SNB committed to unlimited intervention to prevent the franc from appreciating below 1.20 against the euro.

The resulting accumulation of foreign currency reserves — peaking above CHF 900 billion, exceeding Swiss GDP — made the SNB one of the world’s largest holders of foreign assets. The reserve portfolio is invested in foreign government bonds, equities (including publicly listed US and European stocks), and gold.

Minimum Reserve Requirements

Swiss banks are required to hold minimum reserves (sight deposits at the SNB and notes) equivalent to a percentage of their short-term liabilities. This requirement supports the transmission of monetary policy and provides a floor for demand for central bank money.

Impact on the Swiss Economy

Price Stability

The SNB has delivered on its price stability mandate with remarkable consistency. Swiss inflation has averaged approximately 1 per cent over the past 25 years — well below the 2 per cent target and significantly lower than inflation in the euro area, the United Kingdom, or the United States. This price stability preserves purchasing power, reduces uncertainty for businesses, and supports long-term investment planning.

For Canton Zug’s businesses — from commodity traders to manufacturers to financial services firms — low inflation provides a stable cost environment that supports competitiveness.

Exchange Rate Effects

The SNB’s exchange rate management has direct implications for Swiss exporters and multinational companies. A strong franc benefits consumers (through cheaper imports) and firms with foreign cost bases, but penalises exporters and companies translating foreign-currency revenues into Swiss francs. The SNB’s willingness to intervene provides a degree of comfort against extreme appreciation, though the 2015 abandonment of the EUR/CHF floor demonstrated the limits of exchange rate management.

Financial System Stability

The SNB’s financial stability mandate has grown in importance since the 2008 financial crisis. The bank conducts annual financial stability assessments, imposes capital surcharges on systemically important banks, and has advocated for stricter regulation of the banking sector — a role that became acutely relevant during the 2023 Credit Suisse crisis and subsequent forced merger with UBS.

Profit Distribution

The SNB distributes a portion of its annual profits to the federal government and the 26 cantons according to a profit distribution agreement renegotiated periodically. In years when the SNB generates substantial profits (primarily from its foreign currency reserves and gold holdings), these distributions provide meaningful revenue to cantonal budgets. In loss-making years — such as 2022, when the SNB recorded a CHF 132 billion loss on its investment portfolio — no distributions are made.

This distribution mechanism creates a link between SNB performance and cantonal finances, including Canton Zug’s budget.

Current Policy Challenges

Inflation normalisation. After the 2022-2023 inflationary episode, the SNB is navigating a return to low inflation while monitoring the risk of deflationary pressures — a recurring concern for the Swiss economy. See our Swiss inflation analysis.

Reserve management. The SNB’s enormous foreign currency reserves — accumulated through years of intervention — require active management and expose the bank to significant investment losses in unfavourable market conditions.

Digital currency. The SNB is exploring central bank digital currency (CBDC) through its Project Helvetia partnership with the BIS Innovation Hub, testing wholesale CBDC for securities settlement using distributed ledger technology — a development relevant to Canton Zug’s fintech ecosystem.
