As the monetary easing by central banks across the globe keep yields at rock-bottom, investment officers predict that Japanese demand for U.S. debt won't ease up in the months ahead given the lack of alternatives. Japanese life insurers - some of the world’s largest institutional investors - plan to keep pouring money into U.S. debt this year, WSJ reports, outlining that Japan even overtook China in Q1 as the largest foreign holder of U.S. Treasurys. While the current 2% yield on the U.S. 10-year is a far cry from yields of 5% or more before the financial crisis, it is still miles apart from the 0.16% yield on German bunds and the 0.29% yield on the 10-year Japanese equivalent.
