[HONG KONG] Oil prices extended their losses on Monday, adding to worries about the global economy, while Tokyo led most Asian markets lower as a stronger yen hurt Japan's exporters.
With Wednesday's US Federal Reserve interest rate hike well in the past, analysts said concerns about the global economy returned and traders were now looking ahead to the next increase.
However, while markets will begin winding down for the Christmas break Friday there are some key economic figures due for release this week, including US economic growth and home sales as well as Japanese inflation and spending.
