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.

Japan will invest $550 billion in the U.S. and allow the U.S. to tax Japanese goods sold in America at 15 percent.

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