TOKYO: Japan’s 10-year government bond yield rose on Tuesday, as investors remained cautions about a possible surprise tweak by the Bank of Japan to its yield curve control policy at a meeting this week.

The 10-year JGB yield rose 1 basis point (bp) to 0.475%. “Movement of yields shows caution for the BOJ’s tweak in the yield curve control (YCC) policy,” said Keisuke Tsuruta, fixed income strategist at Mitsubishi UFJ Morgan Stanley Securities.

“It is obvious that costs for keeping the YCC policy outweighs the effect for achieving the 2% inflation target.”

At the meeting, which starts on Thursday, the BOJ is expected to keep its monetary settings and dovish policy guidance unchanged to support a fragile economic recovery and budding signs of wage growth.

But the markets remember a shock in December, when the BOJ widened the movement range around 10-year JGBs.
