Japan’s central bank policymakers are expected to keep rates on hold this week, despite the trade deal with the U.S. relieving some uncertainty over tariffs and strengthening the case for tighter policy.

The new U.S.-Japan trade deal lowers tariffs and strengthens economic ties, helping challenge China's regional aggression and instability.

The White House factsheet on the trade deal mentions that Japan will also buy 100 Boeing Co. planes as well as US defense equipment worth additional billions of dollars annually. Akazawa said both these pledges were based on existing plans by Japanese airlines and the government, respectively.
