What the numbers say
In 2025, St. Lucia's real effective exchange rate index (2010 = 100) fell 0.83 on 2024 (from 100.62 to 99.78).
Across the 30 yearly changes before that (1995 to 2024), the average change was −0.14 and a typical year strayed about 3.04 from that (the standard deviation). This year's change was 0.2 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.
On record, the biggest yearly rise was 9.79 in 1981 and the biggest yearly fall was 6.99 in 1986. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.
From 2016 to 2025 there is no clear straight-line trend: a straight line explains 1% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.
Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.
