Like many other economic variables, exchange rates are sometimes thought to be subject to seasonal influences. These could arise from a number of sources, including dependence on industries which are subject to seasonal swings in demand or supply (tourism and agriculture, for example) and financial effects such as the repatriation of overseas earnings ahead of the end of the financial year. In order to identify such patterns, we have adopted a relatively widely used statistical approach, known as X12 ARIMA. Examining end month data from January 1995 to December 2014, we calculated seasonal price changes for 36 of the major currencies we cover. These measure the average deviation of an exchange rate from its trend rate in each month over the past twenty years.

The table and text commentary below represent a small portion of this special survey taken from our April 2015 issue of Foreign Exchange Consensus Forecasts.

*Analysis refers to exchange rate against the euro

Our long-term historical analysis continues to suggest that seasonal influences on currencies are generally modest, particularly once adjustments are made to account for outlying observations. On average, of the 36 major currencies covered in the table below, almost all deviated from trend within a narrow range of plus or minus 1.0%. Estimates for the US dollar (based on NYBOT index weights, as explained on page 3) suggest that it has a slight tendency toward strength in the first half of the calendar year and in August and weakness in September through to December. In contrast, the euro (or its component currencies prior to 1999, which has a significant weight in the NYBOT index) showed the opposite pattern over the same period.
