We revisit the exchange rate half-life issue and demonstrate that observed half-lives can be reduced significantly by modelling (relative) currency rates, rather than exchange rates. We show that the average observed half-life for relative currency rates, around a measure of central tendency, is about 1.55 years and this drops to 1.30 years when the US dollar is excluded. We also show that a standard exchange rate model exhibits aggregation bias.
