WebApr 12, 2024 · Mean reversion refers to the behavior of a time series to fall when its values are above the mean and rise when they are below the mean. This is illustrated as follows: A mean-reverting time series tends to move towards its long-term mean. The model predicts that the value will stay the same if the time series is currently at its long-term mean.

WebJan 11, 2024 · The Vasicek model exhibits a mean-reversion, which helps predict future interest rate movements. As shown in the table below, when market shocks cause the interest rate (or “short rate”) to be higher than the long term mean, the drift factor (dr t = a (b-r t )) is lower than 0 – indicating that the interest rate is likely to decrease.
