This year's change was 1.2 standard deviations below that average, so it was larger than a typical year, though not out of the range seen before.

On record, the biggest yearly rise was 15.1% in 1987 and the biggest yearly fall was 3.8% in 1990. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.
