The Taiwan dollar has touched its highest level in 15 months as investors poured in investment into Taiwan amid continuing global economic uncertainty.

Global investors bought $1.7 billion more Taiwanese stocks during the month and net purchase for the year stood at about $4.9 billion. The Taiwan dollar was trading at NT$29.100 against its US Dollar, according to the latest figures released by Taipei Forex Inc. The Taiwan dollar had touched NT$28.959 on Nov. 12, which is its strongest level since September 2011.

The Taiwan dollar has already appreciated 4.1 percent this year against the US dollar and is set to record fourth straight years of growth. It is believed that the election win by Shinzo Abe's Liberal Democratic Party in Japan would outlook for inflows to the rest of Asia including Taiwan. Analysts believe that the continuity of monetary easing by Asia's second largest economy would boost currencies of the rest of Asia.

The Liberal Democratic Party won 294 seats in Japan's 480-member lower house of parliament, according to reports. Prime Minister Yoshihiko Noda's Democratic Party of Japan lost three- fourths of its members.
