Investing.com - European shares fell; mirroring declines in Asia after the Bank of Japan struck a gloomier tone at its policy meeting. Oil prices which fell up to 4% on Monday, dropped further as oversupply fears continued to weigh. The main European indices were broadly lower, with commodity linked stocks leading losses. Tokyo's Nikkei closed down 0.7% as a stronger yen hurt exporters, while the Shanghai Composite eased 0.2%. The Federal Reserve was starting its two-day policy meeting later in the day, with rates widely expected to remain on hold.
