The Bank of Japan will continue to raise interest rates if inflation moves in line with its forecast, policymaker Junko Nakagawa said, signalling that last month's market rout has not derailed the bank's plan to hike borrowing costs steadily.
But the central bank must take into account the impact that such market moves could have on the outlook for the economy and prices when considering whether to raise rates, she added.
"Given real interest rates are currently very low, we will adjust the degree of monetary support, from the standpoint of sustainably and stably achieving our 2% inflation target, if our economic and price forecasts are met," Nakagawa said in a speech on Wednesday to business leaders in northern Japan.
Her remarks follow those by another member of the BOJ's policy board, Hajime Takata, who said last week the BOJ must stay on course to raise rates - but tread carefully to ensure volatile markets do not badly hurt businesses. The BOJ ended negative interest rates in March and raised its short-term policy rate target to 0.25% in July - landmark actions away from a decade-long, massive stimulus programme.
The July rate hike, coupled with weak U.S. jobs data released in early August, pulled the yen up against the dollar and triggered a plunge in global share prices.
While stressing that there was no major change in Japan's sound economic fundamentals, Nakagawa said the BOJ "must look back upon market developments" after its July policy shift, and assess their impact on the economy.
Nakagawa warned that overseas uncertainties were risks to Japan's economy but said consumer spending will rise moderately due to higher wages, and help accelerate trend inflation.
She also said there were upside risks to Japan's price outlook due to the country's tight job market and continued rises in import prices.
"There's a chance wage growth may overshoot expectations due to tight labour supply, so we need to be mindful of the risk that inflation may exceed our target," Nakagawa said.
Formerly chairperson of Japan's Nomura Asset Management, Nakagawa is considered by markets as neutral in her stance on monetary policy.
