South Korea's won currency surged to a 22-month high against the US dollar on Monday, after the election of Joe Biden as the next US president.

The won was quoted at 1,113.9 won per US dollar at Monday's closing, up 6.5 won from the previous session, touching its strongest level since Jan. 31, 2019.

It was the first time in some 22 months that the currency breached the key support level of 1,120 won to the greenback.

Analysts said the won is expected to further strengthen for the time being, as risks over US politics receded.

Jeon Seung-ji, a currency analyst at Samsung Futures Inc., said the won is expected to show "upward rigidity for the time being" due to the fall of the US dollar.

The US dollar is likely to fall further, as the Biden administration is expected to draw up massive stimulus measures to prop up the pandemic-hit economy, Jeon said.

Baek Suk-hyun, an analyst at Shinhan Bank, said the Biden administration may take a friendlier trade policy toward China, propelling Asia's trade-dependent currencies higher.

However, the won's strength may be limited as new waves of coronavirus infections hit the United States and European nations, analysts said. (Yonhap)
