What the numbers say
In 2025, St. Lucia's real interest rate (%) fell 0.75 percentage points on 2024 (from 4.35% to 3.6%).
Across the 30 yearly changes before that (1995 to 2024), the average change was −0.13 percentage points and a typical year strayed about 4.63 percentage points from that (the standard deviation). This year's change was 0.1 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 17.2 percentage points in 1982 and the biggest yearly fall was 16.95 percentage points in 2021. 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 13% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

What this measures
An interest rate is the amount charged, expressed as a percentage of the principal over a period of time, by the owners of certain kinds of financial assets for putting the financial assets at the disposal of another institutional unit. The real interest rate is the lending interest rate adjusted for inflation as measured by the GDP deflator. The terms and conditions attached to lending rates differ by country, however, limiting their comparability. This indicator is expressed as a percentage (a÷b)*100.
