Japan's real wages climbed 1.9% in April from a year earlier, government data showed on Friday, marking a fourth consecutive monthly gain, as higher special payments boosted overall earnings and improved household purchasing power. Here are a few details: • The Bank of Japan, which will next review its interest rates on June 15 and 16, considers steady rises in wages and prices as a prerequisite for another hike. The Japanese central bank is expected to raise interest rates this month unless a sharp escalation in the Middle East conflict roils markets, sources told Reuters.
