[1/3] Examples of Japanese yen banknotes are displayed at a media event in Tokyo, Japan, November 21, 2022.
Those positions took a hit when Tuesday's Bank of Japan policy shift allowed 10-year yields to almost double to 0.47%.
On Wednesday the long end of Japan's yield curve actually rallied, with 30-year yields down 2.5 bps to 1.545%.
"The 10-year yield is still very low ... maybe they will invest in the 20-year."
In Australia, where Japan is also the largest foreign player in the bond market, 10-year yields are up about 20 bps.
