The ECB has contacted banks on its watch to quiz them on their exposure to the struggling Swiss lender, two supervisory sources told Reuters. Money market pricing suggested traders now saw less than a 20% chance of a 50 basis point rate hike at Thursday's scheduled ECB meeting. That's down from as high as 90% at the start of the session , when a source-based story saying ECB policymakers were leaning towards a half-percentage-point rate hike was published. While rapidly rising interest rates across major economies have raised concern about potential pressure points, many analysts still expected a large ECB hike given high inflation. Pictet's Ducrozet said the ECB could also ease collateral rules for banks, though not as much as the Federal Reserve.
