Swiss National Bank (SNB)

The Swiss National Bank (SNB) is the central bank of Switzerland, responsible for the country's monetary policy and the stability of its currency, the Swiss Franc (CHF). But hold on, this isn't your typical state-owned central bank. The SNB is structured as a special-statute joint-stock company (*Aktiengesellschaft*), meaning its shares are traded on the stock market and are owned by a mix of public institutions (like the Swiss cantons and cantonal banks) and private individuals. This unique setup often sparks curiosity among investors. However, despite its private shareholders, the SNB's mandate is entirely public: its primary goal is to ensure price stability, defined as an inflation rate below 2% per year, while taking the health of the economy into account. It achieves this by setting interest rates, issuing banknotes, and, most famously, intervening in the currency markets to manage the value of the famously strong Swiss Franc.

A Central Bank Unlike Any Other

The SNB's corporate structure is a historical curiosity that sets it apart from institutions like the US Federal Reserve or the European Central Bank.

The Unique Shareholder Structure

While you can buy a share in the SNB, it's not an investment in the traditional sense. Here's why:

The SNB's Mandate and Tools

Like any central bank, the SNB has a specific job to do and a set of tools to accomplish it. Its actions have a profound impact not just on Switzerland, but on global financial markets.

Price Stability: The North Star

The SNB's unwavering focus is keeping inflation low and stable. A stable price environment allows businesses and consumers to plan for the future with confidence, fostering sustainable economic growth. This is the bedrock of its entire policy framework.

The Policy Toolkit

To maintain stability, the SNB uses several powerful instruments:

  1. The SNB Policy Rate: This is its main tool. By raising or lowering this key interest rate, the SNB influences borrowing costs for banks, businesses, and consumers, which in turn affects spending, investment, and ultimately, inflation.
  2. Foreign Exchange Market Interventions: The SNB is famous for its massive foreign exchange market interventions. Because Switzerland is a small, open economy with a “safe-haven” currency, the Swiss Franc can appreciate rapidly during times of global uncertainty, hurting Swiss exporters and creating deflationary pressure. To counter this, the SNB often sells Francs and buys foreign currencies (like the Euro (EUR) or US Dollar), building up enormous foreign reserves. This policy led to the famous “Frankenshock” in January 2015, when the SNB abruptly abandoned its currency peg against the Euro, causing massive market volatility.
  3. Lender of Last Resort: The SNB acts as the ultimate backstop for the Swiss banking system. In a crisis, it can provide emergency liquidity to ensure financial stability, a role that was highlighted during the 2023 rescue of Credit Suisse.

The SNB as a Global Investor

Here's where things get fascinating for the average investor. As a result of its currency interventions, the SNB has amassed one of the largest investment portfolios in the world, making it a whale in the global stock market.

A Giant Equity Portfolio

To manage its hundreds of billions in foreign reserves, the SNB doesn't just hold cash. A significant portion—around 25%—is invested in global equities. It holds large positions in thousands of companies, including household names like Apple, Microsoft, Amazon, and Google. In effect, the Swiss central bank is one of the world's biggest passive investors, resembling a gigantic index fund or ETF (Exchange-Traded Fund). Investors can even track its US holdings, which are disclosed quarterly in 13F filings.

What Can a Value Investor Learn?

While you shouldn't blindly copy the SNB's portfolio—its goals are macroeconomic, not alpha generation—its strategy offers powerful lessons for any follower of value investing:
