The European Central Bank may decide to once again lower the borrowing cost this week, this time with a fairly technical change. The market generally expects ECB officials to lower the key deposit rate by 25 basis points on Thursday, which is the standard magnitude of policy adjustment globally. However, the main refinancing and marginal lending rates are expected to be reduced by 60 basis points, which is not so common. With decision-makers reducing large-scale bond holdings and long-term loans, this move is aimed at injecting lubricant into the financial system. Their goal is to ensure that the ECB maintains market conditions under control during the contraction of its balance sheet.
