### Background and motivation
- Adoption of inflation targeting by the Bank of Korea (BOK) in 1998 contributed to low and stable inflation.
- After the global financial crisis (GFC), monetary policy faced more challenging conditions.
- Inflation slipped below the target range in 2012 and remains below it despite a cut in the target to 2 percent in 2016.
- The central bank’s mandate became more complex with the addition of financial stability.

### Key findings and analysis
- Monetary policy effectiveness has been undermined by prolonged below-target inflation and a broader mandate that includes financial stability.
- A macro model calibrated to Korea can be used to simulate policy and provide a medium-term focus on achieving the inflation target.
- Enhanced communication, supported by a forecasting and policy analysis system, can improve the Bank of Korea’s ability to achieve its inflation objective over the medium term.

### Policy recommendations
- Two-pronged approach:
  - Enhanced communication on how the target will be achieved over the medium-term, building on a forecasting and policy analysis system.
  - Clarify the complementary role of macroprudential policy in containing financial stability risks so that monetary policy can focus on the inflation target.
- Use model-based simulation and forecasting to strengthen medium-term focus and public communication around the inflation target.

### Simulation and tools
- Simulation of a macro model calibrated to Korea illustrates how model-based analysis can:
  - Provide greater medium-term focus on achieving the inflation target.
  - Strengthen communication of policy intentions and expected paths.
