Measuring monetary policy surprises in emerging markets can be difficult due to the complex institutional structures and constantly evolving policy regimes. We outline a two-step estimation procedure and apply it to the context of China. Our approach isolates the common component of interest rate variations driven by monetary policy changes, which delivers a high-frequency measure of Chinese monetary policy shocks. We then identify their causal impacts on daily asset prices and find that monetary policy surprises in China significantly shift inter-bank interest rates, treasury rates, corporate bond yields, and equity prices, leading to substantial effects on macroeconomic aggregates. Our results are consistent with established theoretical predictions, and our methodology adapts to frequent policy changes in emerging markets.
