The cumulative impacts of these factors do not add up to the actual monthly depreciation or appreciation as, due to data limitations, the model does not capture some of the depreciation or appreciation pressure, such as intervention by the authorities and investor positioning. The blue dots denote the actual monthly depreciation or appreciation. The selection of episodes is based on those months when the won rose or fell sharply against the dollar.

Drivers of KRW/USD Rate in Selected Months Likewise, during periods of appreciation pressure on the KRW, portfolio inflows and an increase in the equity index were the main drivers in September 2010, while improvements in risk sentiment and the booming equity market drove up the currency in September 2017.įigure 1. Comparatively, depreciation during the pandemic was mostly due to increased risk aversion and a weak domestic equity market. The depreciation of the KRW in November 2008 during the Global Financial Crisis was broad-based, including widening interest rate differentials, deterioration in the current account balance, the equity market downturn, and portfolio outflows.

In this context, it is imperative to first understand the underlying economic drivers of the KRW/USD exchange. However, excessive foreign exchange rate volatility could have negative impacts on the Korean economy given that many Korean manufacturers have a global footprint and Korea has become a creditor country.
