Ms. Oh has represented the most prestigious corporations, banks and financial institutions and earned a reputation as a brilliant negotiator and strategist in deal structuring. Chambers of Asia and Asialaw named Ms. Oh a leading lawyer in the area of Capital Markets.

During the global financial crisis in 2008 and 2009, Ms. Oh acted as the sole legal counsel to the Bank of Korea for its bilateral currency swap arrangement with the U.S. Federal Reserve Bank (2008) and its multilateral currency swap arrangement with the central banks and finance ministries of ASEAN countries, China and Japan (2009).

Having advised on the issuance of Korean sovereign bonds, the first issuance of non-Korean CD, the first-ever issuance of synthetic exchangeable bonds and redeemable convertible preferred shares in Korea, Ms. Oh has been in the forefront of the debt capital market. She is recognized for her ability to structure complex transactions, such as those involving dual currency bonds, going-public bonds and option stripping of synthetic securities.

During the mid-2000s when Korean companies were actively raising capital overseas by issuing equity-related bonds such as convertible bonds, exchangeable bonds and bonds with warrants, Lee & Ko’s Securities & Capital Markets Group consistently recorded the largest market share among Korean legal counsel in deals involving equity-related bonds. In the field of capital market compliance, Lee & Ko has advised both domestic and foreign financial institutions and helped them minimizing legal risk while maximizing business opportunities.

Ms. Oh represented various local financial institutions and companies in relation to the termination of their derivatives transactions with Lehman Brother entities. She also represented major Korean banks in high-profile litigations involving their KIKO contracts with local export-import companies. As a leading authority in the area of derivatives and on behalf of the Korea Options, Swaps & Derivatives Association and the Korea Federation of Banks, she has drafted the Korean standard forms for derivatives transactions. She has engaged in various ISDA negotiations and documentations and advised a number of multinational clients in relation to structuring of derivatives products, including equity options and CLN/CDS/DLS. In addition, she has conducted compliance checks and obtained foreign exchange approvals for derivatives products.

Ms. Oh has been an active participant at ISDA conferences representing Lee & Ko as a member firm of the ISDA. She is contributing her knowledge to the industry as an advisory member of the Financial Advisory Committee at the Financial Supervisory Service, an expert member of the Financial Disputes Mediation Committee at the Financial Supervisory Service, and a member of Advertisement Review Committee at Korea Financial Investment Association.
