The Fed had its largest hike in two decades, and the ECB has gone ultra-dovish. This has sent a huge influx of Euro area investors into U.S.-short-durations bond ETFs. Funds like the iShares 3-7yr UCITS ETF had over $600 million in inflows last week. Short-duration corporate debt was also favored by euro area investors. Overall the bond market had seen an exodus in the previous weeks but this confluence of factors has been enough to entice investors. While the Fed has made up its mind they have contributed to inflation, bank heads in Europe are mixed which will leave policy to be accommodative for the near term.
Finsum: The Fed could be over-reacting and Europe could be under-reacting to inflation, but if Europe doesn’t tighten they will find their bond market in a similar position to the US a couple of weeks ago.
