I downloaded some data from the World Bank's World Development Indicators database.
I found a time series called Claims on central government, etc (% of GDP) with code
FS.AST.CGOV.GD.ZS which is defined as follows:
Claims on central government (IFS line 52AN or 32AN) include loans to central government institutions net of deposits.
Could someone further explain what this indicator measures? Particularly, could it be used as a proxy of the debt acquired by a country's government?
