Under conditions of increasing environmental uncertainty, firms' risk management become important. This study examines the impact of foreign currency derivative usage on firm value using 3,004 Korean non-financial firms from 2002 to 2007. The results showed that there was no significant relationship between foreign currency derivative usage and firm value for the whole period and from 2002 to 2004 when exchange rate was relatively less volatile. But form 2005 to 2007 when exchange rate was volatile, foreign currency derivative usage gave significant negative impact on firm value, whereas when contract value was used, the relatinship was significantly positive. These results might be come from the characteristics of contract value and fair value of foreign currency derivatives. increased firm value when contract value was used as foreign currency derivative usage measure. But when fair value was used, there was no significance. For control variables, major shareholders ownership and foreign blockholders ownership was positively related with firm value.

The exchange rate volatility during the global financial crisis in 2007-2009 led Korean shipbuilding companies to face currency risk. The use of foreign currency derivatives to take a risk in financial exposure affects them significantly. This research analyzes how the use of foreign currency derivatives affects the Korean shipbuilding industry in relation to its foreign sales by company type and over time, especially before and after the crisis period. It is based on statistical data presented by KOSHIPA and KOSIC in 2001-2014. The results of the analysis show that there is a significant relationship between foreign currency derivatives and foreign currency exposure for all firm sizes and years, but no relationship between them overtime.

영국의 베어링사, 미국의 오렌지 카운티, 미국의 프록터앤 갬블사 등 최근의 유명한 대형금융사고에는 파생금융상품이 관련되어 있었다. 최근 국내에서도 파생금융상품과 관련된 대형금융사고가 발생하였다. SK증권은 $\ulcorner$다이아몬드 펀드$\lrcorner$라는 역외펀드를 설립한 후, JP Morgan과 파생금융상품을 거래하였는데 최근의 동남아 통화위기로 인하여 SK증권은 커다란 손실을 본 것이다. 본고에서는 거래된 파생금융상품에 대한 정밀한 분석을 통하여 SK증권과 JP Morgan은 서로 엔화 및 바트화에 대한 외환옵션을 거래한 것과 동일함을 보인다. 또한 본고에서는 거래된 파생금융상품에 대하여 계약체결시점의 적정가치를 계산한다. 이러한 분석은 파생상품의 위험관리를 위한 가장 중요한 첫 단계가 될 것이다. 분석결과를 요약하면 다음과 같다. SK증권은 JP Morgan으로부터 5,300만 달러를 차입하면서 약 5,800만 달러의 가치가 있는 상환액을 지급하기로 하였으며 또한 약 8,540만 달러의 가치가 있는 인도네시아 루피아화 연동채권을 8,700만 달러를 지급하고 매입하였다 따라서 파생금융상품계약에 따른 전체적인 손실은 약 660만 달러에 이르는 것으로 분석되었다.

We examine whether new derivatives on KOSPI 200 affect volatility asymmetry of KOSPI 200 portfolio, relative to the carefully matched non-KOSPI 200 portfolio. To test the effect or new derivatives trading, we use GJR-GARCH model and newly developed Volatility Ratio(down-market volatility to up-market volatility ratio). Our results show that KOSPI 200 portfolio experiences lower volatility asymmetry than non-KOSPI 200 portfolio after the trading of new derivatives on KOSPI 200, especially after the introduction of stock index options(KOSPI 200 options). For non-KOSPI portfolio, no significant reduction in volatility asymmetry occurred when trading of stock index options began. Also, we find that in the period of after January 1999, the period of after do-regulations and Financial Crisis in the Korean capital market, volatility asymmetry of stock markets was significantly decreased. This means that level of volatility asymmetry is closely related to the level of market regulations. Further, the results of the paper show that leverage effect and changes in foreign exchange ratio can be good candidates for explaining the stylized volatility asymmetry in the Korean stock market.

This study investigates the impact of exchange rate and exchange rate volatility on the stock prices of eight industries from 2006 to 2015. The first and second exchange rate exposure of these eight industries is estimated with respect to four different exchange rates, namely the US dollar, Japanese yen, European currency unit, and British pound. In exchange rate exposure, stock prices in foods-beverages, paper-wood, electricity-gas, and banks industries are negatively related to exchange rate, whereas stock prices in electrical-electronic equp. and transport-equp. industries are positively related to exchange rate as expected. However stock price in machinery industry is negatively related to exchange rate, which is opposite to the expectation. Negative relationship is found between stock price in chemicals industry and exchange rate. In exchange rate volatility exposure, stock price in paper-wood industry is found to be negatively related to exchange rate volatility. Stock price in banks industry is also negatively related to exchange rate volatility. This result is opposite as expected, because banks are supposed to get more revenue by issuing derivatives related to foreign exchange when exchange rate volatility increases.
