Persistently Elevated Uncertainty Is a Downside Risk to the Outlook

If uncertainty stays elevated for an extended period, it will have a more negative impact on the economy, see chart below, which shows the impulse responses of a temporary and a permanent shock to economic policy uncertainty in a vector autoregression model with GDP and economic policy uncertainty.

The longer uncertainty stays elevated, the bigger is the downside risk to the economy
Note: Impulse response from the VAR model with variables log (Real GDP) and log (Economic Policy uncertainty index). A one standard deviation shock to economic policy uncertainty leads to a -0.2% point decline in Real GDP. Temporary shock is defined as a four standard deviation shock in Q1, and permanent shock is defined as a four standard deviation shock in Q1, three standard deviation shock in Q2, two standard deviation shock in Q3, and one standard deviation shock in Q4.
