Chart 2B: Inflation scenarios
The outlook for inflation was highly uncertain at the time of our March 2023 forecast: the UK was experiencing the largest inflation shock since the 1980s, and the first significant shock in the era of independent inflation-targeting central banks. In this box, we reviewed the ways we have presented uncertainty in our successive EFOs, in particular our use of fan charts and scenarios.
Chart 4.C: 10,000 simulations of current balance and change in PSND in 2024-25
We illustrate the uncertainty around our forecasts using a variety of approaches. This box described using stochastic simulations to produce fan charts, which could be used to enhance presentation of uncertainty in future EFOs, and showed some experimental results.
