Korean Financial Markets and Foreign Exchange Policy Framework
Domain 8 tests the institutions, statutes and macroprudential tools that define Korea's open but managed financial system. Expect questions on who does what, how foreign investors access the market, and how policy levers are calibrated.
Institutions and framework
- The BOK sets the base rate, manages reserves and provides liquidity; the MOSF owns FX policy and the Foreign Exchange Stabilization Fund; the FSC and FSS handle policy and supervision; KRX and KSD handle trading and settlement.
- The Foreign Exchange Transactions Act liberalised current transactions and applies a negative-list approach to capital transactions, but reporting duties survive liberalisation.
- Foreign investors: the investment registration certificate was abolished in December 2023 and replaced by LEI-based registration with the FSS; omnibus accounts are permitted.
- Seoul FX trading runs 09:00–02:00 with registered foreign institutions since July 2024; FTSE Russell announced WGBI inclusion beginning November 2025.
Macroprudential tools
- FX levy on non-deposit foreign currency liabilities, banded by maturity at roughly 0% to 0.2%, penalising short-term dollar borrowing.
- FX forward position limits: 50% of equity capital for domestic banks, 250% for foreign bank branches.
- Foreign currency LCR and NSFR requirements, plus smoothed intervention and swap lines with major central banks.
Worked example
A bank holds USD 5bn of non-deposit FX liabilities with a blended levy rate of 0.08%. The annual levy is USD 4m. If the maturity mix shortens and the blended rate rises to 0.15%, the cost becomes USD 7.5m - the regulator's lever works through the maturity composition, not the total size of the book.
Traps that cost marks
Attributing FX policy to the BOK rather than the MOSF; assuming WGBI inclusion mechanically strengthens the won; treating the levy as applying to all FX liabilities including deposits; forgetting that reporting obligations persist under the negative-list regime.
