The Japanese central bank’s governor and other officials have voiced concerns about rising uncertainty over the impact of U.S. trade policy and how other countries will respond.

The Bank of Japan on Thursday left its key interest rate unchanged but revised down its growth forecasts, warning that US trade tariffs are fuelling economic uncertainty. Bank officials began lifting borrowing costs last year after nearly two decades of ultra-loose monetary policies aimed at kickstarting torpid economic growth in Japan.

The Bank of Japan kept interest rates steady and sharply cut its growth forecasts today, suggesting uncertainty surrounding US tariffs and the hit to exports could keep policy in a holding pattern for some time.
