The yen rose against all of its 16 most-traded counterparts amid investor concern that Chinese manufacturing was weaker as official government data conflicted with a private-sector purchasing-manager index. The Chinese purchasing manager’s index released yesterday by the country’s logistics federation and National Bureau of Statistics for March rose to a one-year high of 53.1. In contrast, a PMI from HSBC Holdings Plc and Markit Economics showed manufacturing contracting and export orders declining. The index fell to 48.3 in March from 49.6 the previous month. The Tankan index for Japan’s largest manufacturers was unchanged last quarter from minus 4 in December, the BOJ said today in Tokyo. A negative number means pessimists outnumber optimists.

Fifty is the dividing line between growth and contraction. The Reserve Bank of Australia will hold a policy meeting tomorrow.
