Last Monday the Bank of Japan bid for Japanese Government Bonds (an unlimited amount) as yields rose. They did the same on Friday (when the JGB yield hit 0.1% … recall the BOJ target is around zero %)
Yield is on the up again today, around 0.1% as I post, which has set in motion the chatter the BOJ may well be back with another b for JGBs today
