After 10Y JGBs sold off early in the session, with yields rising as high as 0.11% - the highest level in almost a year and a half - as the market continues to test the Bank of Japan's intentions ahead of its policy decision, on Monday morning, the BOJ intervened again, offering to buy an unlimited amount of bonds for a third time in a week.

While unlimited in size, the central bank offer, made at 0.1% for bonds with 5-10 year maturities, drew some 1.6 trillion yen ($14.4 billion) of bids which were all accepted, the central bank reported just around 1am EDT. The 10-year yield pared the day's advance after the move was announced.
