But the Fed's tightening which began this year by raising rates three times could result in a capital outflow from the same emerging countries, Lee pointed out.

South Korea is less vulnerable to an economic crisis that could result from a massive capital flight due to its solid financial fundamentals compared to other emerging markets, he added.

This year, the Fed raised the cost of borrowing by 0.75 percentage point to a range of between 1.25 percent and 1.50 percent. It is widely expected to raise rates three more times in 2018.

If the Fed raises rates, investors are expected to reorganize their portfolios by converting their financial investments in emerging markets to safer assets.

The institutes checked include such organizations like Korea Institute of Finance Korea (KIF), the Korea Institute for Industrial Economics & Trade (KIET) and the Korea Institute for International Economic Policy (KIEP).

Chiefs of such think tanks also said rising oil prices and North Korea's nuclear weapons development program will pose major challenges for the Korean economy next year.

"There might not be a sharp increase in oil prices as an increased oil production in the United States offsets an extended output reduction by oil majors. But heightened political unrest in the Middle East could increase volatility in oil prices," KIET President Yu Byoung-gyu said.

Geopolitical risks such as escalating North Korean provocations with nuclear ambitions and political tensions between Seoul and Beijing over a US missile defense system in South Korea remain factors which could affect the economy, Yu said. (Yonhap)
