ECB asset purchases: the three transmission channels
A new paper suggests that ECB asset purchases influence markets and the economy significantly, mainly through three channels. First, through the asset valuation channel they reduce risk premia and provide capital relief to leveraged institutions, particularly banks. Second, through the signalling channel they enhance the credibility of rates staying low for long. Third, through the re-anchoring channel, asset purchases can reassure the private sector that the central bank remains committed to its long-term inflation target.
