Apple (AAPL.O) CEO Tim Cook said Mac sales in Greater China were particularly strong in Q3.

The yen unexpectedly strengthened on Friday, raising market concern that Japan may again intervene in FX markets. A market source said Japanese authorities bought yen and sold dollars during Thursday's New York session — the first such intervention in three months — after the currency had fallen to a 40-year low. Traders flagged that an Iran war-related energy shock has pushed up living costs and that further yen weakness could amplify that pressure. USD/JPY plunged roughly 150 pips to 158.53 on Friday. It is unclear what drove the move or whether Tokyo intervened again; Japan's Finance Ministry (MOF) has not responded.

Daiwa Securities chief FX strategist Kenta Tadaide said any surprise Japanese government intervention to support the yen may only be a stopgap to buy time. "To maximize the effect of FX intervention, monetary policy must remain aligned," he said, adding markets largely expect the Bank of Japan to keep policy rates unchanged at today's decision and are focused on the policy statement and Governor Kazuo Ueda's press conference.
