Deutsche Securities chief economist Kentaro Koyama said the Bank of Japan would
need to fully explain any decision to halt tapering of its monthly bond
purchases, particularly after media reports that the government might tacitly
permit further rate hikes only if tapering is stopped. He warned that if the BOJ
both raises rates and stops tapering, markets and the public could interpret it
as a political deal with the government, creating a serious risk of questions
over the BOJ's independence.
