BOJ's Asada warns against rushed rate hikes despite December lift still possible

Toichiro Asada, a member of the Bank of Japan's policy board, is not yet prepared to support a rapid tightening of monetary policy. The central bank's most dovish figure has once again urged restraint, cautioning that additional rate increases could jeopardise Japan's progress toward stable inflation.

His comments from today include the following points:

• With inflation already around 2%, there is little justification for driving prices higher
• The BOJ must exercise caution in raising interest rates too rapidly
• While future rate hikes might be needed, they should be implemented gradually
• He is not opposed to rate increases and has no intention of proposing a cut
• Japan's neutral interest rate could be slightly above the current policy rate
• He has no specific terminal rate in mind
• Policy choices should be evaluated at each meeting, taking account of economic risks and financial conditions
• The BOJ could still adjust rates either way even after reaching a level consistent with its inflation goal
• The BOJ does not directly manage exchange rates (he declined to specify a desirable USD/JPY level)
• Tightening too much risks sapping underlying inflation, especially since consumption remains sluggish

The dovish tone should not be overinterpreted. Asada's call for caution aligns broadly with the BOJ's general communication that future rate decisions will depend on incoming data and financial conditions.

Moreover, Asada is known for his dovish leanings, having voted against rate rises in June and September. His reservations are therefore not particularly surprising.

Markets currently assign roughly 73% probability to a 25 basis-point rate hike in December. That suggests traders remain fairly confident the BOJ will tighten again before year-end.

However, much can shift over four weeks, and the views of other BOJ board members will become clearer in the coming period.

As for the yen, the immediate impact of Asada's remarks is limited. With USD/JPY trading near 160.00, the key drivers remain the diverging outlooks of the Fed and the BOJ, together with intervention risks.
