Unlike the Fed or the ECB, whose mandates focus primarily on inflation and employment, the SNB places central importance on the stability of the Swiss franc. Considered a safe-haven currency, the franc tends to appreciate during periods of market stress, which penalizes the country's export-oriented economy.

To counter this pressure, the SNB does not refrain from intervening directly in the foreign exchange market. It engages in massive purchases of foreign currencies to curb the appreciation of the Swiss franc, a practice far more frequent than among its peers.

This strategy has led the SNB to accumulate vast foreign exchange reserves, making its balance sheet one of the largest in the world relative to GDP. A notable peculiarity: these reserves consist not only of bonds but also of international equities, particularly US stocks.
This atypical positioning makes the SNB resemble a sovereign wealth fund in some respects, even if its objective remains monetary. Few central banks take such significant positions in equity markets.

The SNB was also a pioneer in adopting negative interest rates, introduced as early as 2015 to discourage capital inflows into the franc. This policy was maintained for several years, much longer than in other currency zones.

A publicly traded central bank

Another singularity: the SNB is one of the few central banks with a portion of its capital listed on the stock exchange. Its shares are traded on the Swiss market alongside private investors, even though the cantons and public entities remain majority shareholders. However, this listing confers no specific power to private shareholders over monetary policy. Voting rights are restricted and dividends are capped to preserve the institution's independence. Nevertheless, this hybrid structure remains unique among major central banks.

More discreet communication than its peers

Another notable difference: the SNB communicates less frequently than its major counterparts. Its monetary policy decisions are quarterly, compared to the more frequent pace of the Fed or the ECB, and its forward guidance is generally more limited.

This discretion reflects a pragmatic approach, allowing for significant flexibility in the conduct of monetary policy.
