May was a very strong month for the U.S. dollar and that was no surprise to our readers because we shared this chart at the beginning of the month showing how well the dollar performs in May. With last month’s gains, the positive seasonal bias continued for 7 straight years but on this first day of June, we are more interested in how seasonality affects currencies in the new month.
Which is why we updated our seasonality tables –
As you can see, there’s a negative bias for the Dollar Index in June. After strong performance in May, profit taking tends to drive the greenback lower in June. The seasonal trends are strongest for GBP/USD, EUR/USD and AUD/USD. However the gains in general are relatively modest with the dollar giving back only part of the past month’s moves.
Seasonal trends are important but with the Federal Reserve poised to make a major decision in June and the U.K. holding a referendum on E.U. membership – this year’s unique factors could easily overshadow seasonal trends. With that in mind, if the U.K. votes to remain in the European Union (and we think they will), the corresponding relief rally could drive the dollar lower against sterling and other high beta currencies.
