Moves by Japan's central bank to stimulate the economy have sent the yen plunging against the Singapore dollar.

The yen fell to its lowest level in more than a decade against the Singdollar on Monday.

One Singdollar bought about 68 yen a year ago. It now gets about 83 yen, an increase of more than 20 per cent.

This spells good news for Singapore businesses that import goods from Japan, as well as holidaymakers who have already been flocking to Japan to take advantage of the weaker currency.
