Dollar-yen is struggling to rise, trading from the low to high ¥157 range. The Nikkei 225 has fallen more than ¥1,000 alongside the sharp drop in US stocks in after-hours trading, while the US 10-year Treasury yield has declined to around 4.91%. Trading is subdued ahead of the Bank of Japan's policy announcement.
Dollar-yen rose to ¥157.90 around 9:00 a.m., but buying failed to continue, and it is trading around ¥157.73. Intel and Amazon shares plunged in after-hours trading, South Korean stocks fell more than 3%, and the Nikkei 225 extended its decline to more than ¥1,000.
The US 10-year Treasury yield in after-hours trading fell to around 4.91% amid risk-off moves.
