IRONORE/ Mining behemoths BHP Group BHP.AX and Fortescue Metals Group FMG.AX fell 2.5% and 1.1%, respectively.

Expectations for more hikes from central banks pushed yields higher after Britain reported a slight decline in inflation in March, but remained the only country in western Europe in double-digits.
