Wikirating needs somebody who wants to update the economic data for the SWI.

List of countries by credit rating

Last update: 2020-12-31 - Credit rating table


The Sovereign Wikirating Index (SWI) uses the following five criteria (with weights):

The resulting value is adjusted by multiplying it with a Scaling factor, which is composed by the Human Development Index (HDI)[1] (60% weight), the Corruption Perceptions Index[2] (20% weight) and the Political Instability Index[3] (20% weight).


Each criterium is calibrated with respect to the relative minimum and maximum value of all countries. For some criterion a threshold value is defined in order to avoid distorted values. The calculated values are done with a spreadsheet (wr_swi_method+data_2011-09-26.xls).

Short Title Long Title Value Weight Real Min Real Max SWI Min SWI Max
HD Human Development Index Weighted index of development indicators 0.6 0 1 0 1
CO Corruption Perceptions Index Index of perceived corruption 0.2 0 10 0 1
PI Political Instability Index Index of political instability 0.2 0 10 0 1
PD Public Debt Debt/GDP as %, reflects the economies ability to honour loans. 0.5 0 inf 15 90
AB Current Account Balance Current account balance as % of GDP, reflects foreign inflows and outflows. 0.2 -inf +inf -20 20
PG GDP Growth Domestic growth an an annual % 0.1 -1 inf -0.1 0.1
IR Consumer Price Index CPI as % 0.1 -1 inf 0.02 0.2
UR Unemployment Rate Rate of unemployment as % 0.1 0 1 0.03 0.3
R Rating Result of SWI calculation 1 0 100 0 100




General Variable Modifiers

For example, the variable AB.

  • AB = Number used in calculations for SWI.
  • rAB = Raw or real value, actual data from source in whichever format it is acquired.
  • wAB = Weighting value for the data.
  • minAB = Floor value of variable, will cause ABC to equal 0 or 100 if ABC is below this value.
  • maxAB = Ceiling value of variable, will cause ABC to equal 0 or 100 if ABC is above this variable.
  • nAB = Number of ratings (for rating)

So for instance, if the real value (rAB) was 4 on a 10 point scale, this would be divided by 10 to create the value for calculations (AB) which, in calculations, is multiplied by the weighting (e.g. 0.5 for 50% weight.)

Scaling Factor

  • HD =
  • CO =
  • PI =
