Monetary policy is a powerful tool that plays a crucial role in shaping the economy, influencing both inflation and real economic activity. The impact of monetary policy, however, may not always be consistent across different economic states, such as periods of rapid growth or recessions. This raises the question of how effective monetary policy is in various economic conditions, especially in the context of the UK economy.
In this study, we delve into the effects of monetary policy shocks on inflation and economic activity, aiming to provide insights into how monetary policy transmits in the UK economy. By combining innovative empirical strategies and high-frequency monetary policy surprises, we seek to uncover the state-dependent nature of monetary policy effects.

Linear Effects of Monetary Policy Shocks
Before exploring the state-dependent effects of monetary policy, it is essential to understand the linear transmission mechanism. Contrary to popular belief, the impact of contractionary monetary policy shocks unfolds gradually over a period of 24-48 months. A surprise tightening of monetary policy, of 100 basis points, leads to a 5% decrease in the price level, a 10% drop in industrial production, and a 2-percentage point increase in unemployment. These patterns align with theoretical predictions and previous empirical studies. However, the prolonged time lag between monetary policy actions and their effects highlights the complexities of the transmission mechanism in the UK economy.

State-Dependent Effects
The state-independent impulse response functions depicted in Chart 1 may obscure the diverse impacts of monetary policy shocks under different economic conditions. Considering the pace of economic growth as a defining factor, we categorize periods of low output growth as recessionary phases. The probability of the economy being in a low output growth state fluctuates over our sample period, with peaks around the global financial crisis and other challenging economic times. This variability sheds light on the importance of accounting for different economic states when examining the effects of monetary policy.

In conclusion, analyzing the state-dependent effects of monetary policy is crucial for understanding its effectiveness in shaping inflation and economic activity. By unraveling the complexities of monetary policy transmission under varying economic conditions, we can enhance our policy-making strategies and adapt to the dynamic nature of the economy.
