There is no set time for BOJ announcements, but it usually happens around or just after midday Tokyo time. USD/JPY has been edging lower through the morning on exporter selling as well as risk-aversion plays in AUD/JPY and NZD/JPY. Prime broker reports suggest that overall hedge fund positioning in USD/JPY is quite neutral but they remain very short EUR/JPY and are still selling rallies in AUD/JPY and NZD/JPY.
