Questions and answers on monetary policy implementation

  • How does the SNB implement its monetary policy?

    The SNB implements its monetary policy by setting the SNB policy rate. The SNB policy rate is the third element of the SNB's monetary policy strategy in addition to the definition of price stability and the conditional inflation forecast (Questions and answers on monetary policy strategy). The SNB seeks to keep the secured short-term Swiss franc money market rates close to the SNB policy rate. SARON is the most representative of these rates today. In 2020, the SNB’s monetary policy was based on the SNB policy rate and the interest on sight deposits at the SNB, which remained unchanged at –0.75% (negative interest), as well as the willingness to intervene in the foreign exchange market. As of June 2019, the SNB policy rate replaced the target range for the three-month Swiss franc Libor (London Interbank Offered Rate) previously used in the SNB's monetary policy strategy.

  • Since when has the SNB been charging negative interest?

    Negative interest has been charged since 22 January 2015, with the SNB granting the banks exemption thresholds (Questions and answers on repo transactions and other monetary policy instruments). The negative interest rate currently corresponds to the SNB policy rate. From 6 September 2011 to 15 January 2015, the main focus of implementation was on the minimum exchange rate of CHF 1.20 per euro, which the SNB enforced during this period. On 18 December 2014, the SNB decided to impose an interest rate of -0.25% on sight deposit account balances. With the announcement of a negative interest rate, the Libor target range used then was taken into negative territory for the first time, and extended to its usual width of 1 percentage point. On 15 January 2015, the SNB lowered the interest rate on sight deposits to -0.75% and moved the target range downwards to between -1.25% and -0.25%.

  • What is SARON?

    SARON (Swiss Average Rate Overnight) is a secured overnight rate based on the most liquid segment of the Swiss franc money market. It is calculated on the basis of concluded transactions and tradable prices (quotes) from the interbank repo market. In recent years, SARON has gained in importance in Switzerland as a reference rate for financial products and is the most representative of the short-term money market rates today.

  • What is the three-month Libor for Swiss franc investments?

    The three-month Libor for Swiss franc investments, which is published daily in London, corresponds to the trimmed mean of the interest rates reported by leading banks for unsecured Swiss franc interbank loans with a three-month maturity. The three-month Libor was an important benchmark for credit relationships in Switzerland and abroad for a long time and was used by the SNB as a reference rate until 2019. The SNB implemented its monetary policy by setting a target range for the Libor for three-month interbank loans in Swiss francs and, as a rule, aimed to keep it in the middle of the range. Owing to the absence of underlying money market transactions, the Libor has become less relevant and will no longer be supported by the UK Financial Conduct Authority after 2021. In Switzerland, the National Working Group on Swiss Franc Reference Rates, which is the body responsible for drawing up reform proposals for Switzerland and monitoring developments abroad, has recommended SARON (Swiss Average Rate Overnight) as the alternative to the Swiss franc Libor. At the beginning of March 2021, the administrator of Libor, the Intercontinental Exchange Benchmark Administration, announced its intention to discontinue its calculation of the Swiss franc Libor at the end of 2021.

  • Why did the SNB decide that June 2019 was the right time to replace the target range for the three-month Libor previously used in the SNB's monetary policy strategy with the SNB policy rate?

    The SNB's monetary policy is focused on the medium term and the quarterly inflation forecast is based on the assumption that a specified interest rate remains unchanged over the entire forecast horizon of three years. In June 2019, the inflation forecast extended into 2022 for the first time, i.e. beyond the expected end of the Libor. The changeover to the SNB policy rate on 13 June 2019 ensures that the inflation forecast remains based on the same interest rate over the entire forecast horizon.

  • What are monetary policy instruments?

    Monetary policy instruments are transactions through which the SNB implements its monetary policy. Art. 9 of the Federal Act on the Swiss National Bank (NBA) defines the transactions that the SNB may conduct in the financial market. The SNB distinguishes between open market operations and standing facilities. In the case of open market operations, the SNB takes the initiative in the transaction, while for the standing facilities it merely sets the conditions under which counterparties can obtain liquidity. Regular open market operations include repo transactions and the issuance of SNB Bills. The interest rate (currently negative) on sight deposits, which was introduced on 18 December 2014, is a monetary policy instrument, too (Questions and answers on repo transactions and other monetary policy instruments). Further instruments, such as foreign exchange swaps (Questions and answers on foreign exchange swaps) and foreign exchange transactions, are available if necessary. Standing facilities include the liquidity-shortage financing facility and the intraday facility, details on which can be found in the Guidelines of the Swiss National Bank on Monetary Policy Instruments and the relevant instruction sheets. They also include the SNB COVID-19 refinancing facility, a temporary standing facility established in March 2020.

  • How can the SNB implement its monetary policy by means of monetary policy instruments?

    The SNB implements its monetary policy by managing liquidity on the Swiss franc money market and thereby influencing the level of interest rates. In so doing, it sets the SNB policy rate and seeks to keep the secured short-term Swiss franc money market rates close to it. In this regard, the SNB is focusing on SARON, which is currently establishing itself as the most important reference rate for financial products in Switzerland. The SNB can steer money market rates by way of the conditions it sets in respect of interest on sight deposits, or indirectly by influencing the volume and conditions of liquidity-providing and liquidity-absorbing money market transactions. The choice of liquidity management regime depends on monetary policy requirements and the liquidity structure in the banking system. In order to fulfil its monetary policy mandate, the SNB may also purchase and sell foreign currency against Swiss francs on the financial markets. Foreign exchange transactions are conducted with a wide range of domestic and foreign counterparties.

  • What roles do sight deposits and the money market play?

    In order for a bank to maintain its solvency, it must have sufficient liquidity at all times. A bank's most liquid assets are sight deposits held at the SNB, since they can be used immediately to effect payments and are deemed to be legal tender. Domestic banks hold sight deposits to satisfy minimum reserve requirements. Banks also need them for payment transactions and as liquidity reserves. The SNB influences sight deposits through the use of its monetary policy instruments. Liquidity adjustments between the individual financial market participants are effected on the money market. Banks seeking to place funds on a short-term basis provide liquidity in the form of a loan to other banks that require short-term refinancing. These loans can be granted on a secured or unsecured basis. In principle, the level of sight deposits influences activity on the money market. Since 2015, the negative interest rate on sight deposits held at the SNB by banks and other financial market participants, together with the exemption thresholds, has had an impact on developments in the money market. Institutions with sight deposits over and above the exemption threshold can conclude money market operations with institutions which have not yet exceeded their threshold. A well-functioning money market is essential for the transmission of monetary policy. A disruption in the money market impairs the liquidity adjustment process between the market participants and can threaten the solvency of the banks.

  • Is the high level of sight deposits at the SNB a sign that banks are hoarding their money at the SNB instead of putting it into circulation?

    The total level of sight deposits at the SNB (sight deposit account balances of domestic banks and other sight deposits, i.e. sight liabilities towards the Confederation, sight deposits of foreign banks and institutions, as well as other sight liabilities) can only be changed through SNB monetary policy operations or through exchange against cash. If a bank reduces its sight deposits at the SNB, the amount is either transferred to another sight deposit account with the SNB or is put into circulation. This is why the monetary base, which by definition is made up of domestic banks’ sight deposits and banknotes in circulation, can only be changed by the SNB. The growth rates of loans and monetary aggregates (Notes on the data portal) reflect the extent to which the available liquidity has entered the economic cycle.

  • What counterparties are admitted to the SNB's monetary policy operations?

    In principle, all banks domiciled in Switzerland and the Principality of Liechtenstein with sight deposits at the SNB are admissible as counterparties in monetary policy operations. Other domestic financial market participants, such as insurance companies, and foreign banks may be admitted as counterparties in monetary policy operations, provided there is a monetary policy interest and they contribute to liquidity on the secured Swiss franc money market.

  • Why does the SNB also provide liquidity for banks abroad - does it not conduct its monetary policy on behalf of Switzerland?

    The Swiss franc money market is not limited by geographical boundaries. The Swiss franc is one of the most important currencies on the international financial market and is therefore also actively traded abroad. It is thus also in the interests of Switzerland if banks domiciled abroad can participate in the SNB's liquidity-absorbing and liquidity-providing money market operations too.

  • How does the SNB conduct its open market operations?

    The SNB can carry out its open market operations in the form of auctions or bilateral transactions. Transactions on the money market are usually conducted via an electronic trading platform. Auctions are conducted either by volume tender or by variable rate tender. In the case of volume tenders, the interest rate is fixed and amounts are allocated in relation to demand. If, for example, demand is twice as high as supply, each bank receives 50% of the amount it bid for. In the case of variable rate tenders, banks bid for variable amounts at given interest rates. The most favourable bids are considered until the desired overall amount has been reached. Variable rate tenders are conducted to provide or absorb liquidity according to either the American method (bids considered are satisfied at the interest rate offered) or the Dutch method (participants making the bids considered pay or receive the interest rate called by the last bidder considered).

  • What procedures does the SNB apply for its open market operations?

    Repo auctions are, as a rule, conducted by volume tender, whereas auctions of SNB Bills are conducted in the form of a variable rate tender with allocation according to the American system. The SNB does not use variable rate tenders according to the Dutch allotment system for its monetary policy-related open market operations. It does, however, auction Swiss Confederation bonds and money market debt register claims in this manner on behalf of the Confederation.
