Which is a main function of the European Central Bank?

• A. Setting wholesale lending rates in the Eurozone area
• B. Fixing the exchange rate of the Euro against other currencies
• C. Setting rules for financial institution dealings with consumers
• D. Supervising the solvency of life assurance companies

Answer: (A)

The main idea here is that the ECB’s job is to conduct monetary policy for the euro area, primarily by setting policy rates that steer liquidity and inflation expectations. These policy rates determine the cost of money for banks, so they directly influence wholesale lending rates across the banking system. When the ECB adjusts its key rates, banks’ wholesale funding costs change, which then affects the interest rates they charge businesses and households.

Fixing the euro’s exchange rate isn’t the ECB’s role because exchange rates are largely market-driven, with central bank actions influencing but not pegging them. Setting rules for how financial institutions deal with consumers and supervising the solvency of life assurance companies fall outside the ECB’s main mandate (consumer protection rules and life insurer solvency are handled by other EU bodies and regulators).
