Brunei Darussalam: Bank capital to assets ratio (%)

Key figures

What the numbers say

In 2022, Brunei Darussalam's bank capital to assets ratio (%) fell 0.35 percentage points on 2021 (from 10.08% to 9.74%).

Across the 11 yearly changes before that (2011 to 2021), the average change was +0.08 percentage points and a typical year strayed about 1.44 percentage points from that (the standard deviation). This year's change was 0.3 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 2.72 percentage points in 2013 and the biggest yearly fall was 1.87 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 2013 to 2022 there is no clear straight-line trend: a straight line explains 5% 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.

What this measures

The indicator is a measure of capital adequacy that evaluates the financial strength of deposit takers by comparing Tier 1 capital to total assets. Tier 1 capital, often referred to as core capital, includes the most stable and readily available forms of capital, such as common equity, disclosed reserves, retained earnings, and certain other instruments that meet regulatory requirements under the Basel framework. This capital is considered the highest quality because it is fully available to cover losses and does not need to be repaid.

Limitations: Reporting countries compile the data using different methodologies, which may also vary for different points in time for the same country. Users are advised to consult the accompanying metadata on the IMF FSI website (data.imf.org) to conduct more meaningful cross-country comparisons or to assess the evolution of the indicator for any of the countries.
