The ECB’s Sterilization Policy And Its Fiscal Effects

First of all, it’s obvious that I have horribly failed at something I always try to do when writing a new post: coming up with a title that hopefully makes people actually want to read it. Yet I still feel this is important, and I’m thankful to Max for insisting on continuing the discussion. In the comments section of my last post, originally meant more as a general monetary policy post, a vivid discussion has emerged on what the ECBs Outright Monetary Transactions Policy (OMT) entails and particularly in what way it would potentially lead to fiscal transfers between Eurozone members, potentially making it illegal under EU treaties. While writing my latest comment, I noticed it was getting way too long, so let me offer a response as a new post.

The way I see it, the main disagreement between Max and me involves the direction any possible fiscal transfers would go if the ECB would, some day, actually buy bonds under the OMT program. We don’t seem to disagree on the fact that any purchases of government bonds by the ECB would potentially prove legally problematic, but rather on what these purchases would entail economically with regards to possible fiscal transfers within the Union. Max argues that, through sterilization, i.e. the ECBs attempts to remove an equal amount of money from the market as it is injecting by buying government bonds of troubles periphery countries, it is substituting low-risk assets on its balance sheet for high-risk assets, making its entire balance sheet more risky and thus representing a real cost to the core, which gets their share of any interest payments accrued from these assets (and thus potentially stands to loose these due to their increased riskiness). However, it would seem that this is based on an inaccurate description of how the ECB conducts (and would conduct) said sterilization. That no OMT purchases have ever actually taken place does not really make the issue harder – for all intents and purposes, OMT is just a replacement for the Securities Markets Program (SMP) instituted by the ECB in 2010 and under which it has already bought around €200 billion worth of bonds of periphery countries (mostly Italy), most of which it still holds on its books. Although there might be some technical differences, conceptually it would seem to me that the main feature of the “change” is that OMT made this program open-ended (thus also reducing the actual need to buy the bonds in the first place). So we know pretty well how OMT as well as sterilization measures would work – so how would they?
