The highest point of a fluctuation. Where an economic variable has a trend, it may be necessary to distinguish between a peak in the sense of an absolute local maximum, and in the sense of a maximum relative to trend. If a country's real GDP has a trend growth rate of 3 per cent, for example, one may wish to identify as a peak in the trade cycle a year following which GDP growth falls below 3 per cent, even though it is still rising in absolute terms.
