Intuitively traders get a sense of volatility cycles as they occur with their favorite currencies. Here's some perspective for you to consider when looking at each of the majors using weekly data.
Three of the majors stand out as having increased volatility when looking at the shorter-term 5 and 10 week volatility compared to where they have been over the last two years. Longer-term 30 and 120 week volatility remains quite low across the board. However, this should also serve as a warning. Volatility tends to recycle when least expected.
