[1/2] A view shows the logo of the European Central Bank (ECB) outside its headquarters in Frankfurt, Germany March 16, 2023.
The ECB has hiked rates by 350 basis points since last July, lifting its benchmark refinancing rate to 3.5% on Thursday.
Wunsch said the ECB had a "long way to go" if its baseline inflation forecast materialised.
Credit Suisse was dealing with "a longstanding restructuring problem", he added.
Asked about the future of Credit Suisse, Wunsch said he only saw a "very low" likelihood that the bank might go bankrupt.
