TOKYO -- The Bank of Japan's decision to implement negative interest rates is weighing down corporate bond yields, raising concerns of a shrinking market as returns on better-ranked debt dip below zero.
The Japan Securities Dealers Association publishes daily reference statistical yields for over-the-counter corporate bond transactions, to give investors a better view into the often opaque market. Japanese government bond yields plunged after the BOJ's Jan. 29 announcement on negative rates, followed by a downturn in the reference yields of corporate bonds as well.
