A debt security (because Sovereign entities can hardly issue equity, can they?) issued by a soverieng entity.

Depending on the credit quality of the sovereign, govvies can be seen as unimpeachable articulations of the golden mean (US Treasuries), safe as houses (G7 government bonds) or a hair-raising ride through the valley of death (Central and South American government debt, most notably that of Argentina[1]).

Don’t cry for the bond market, Argentina

As recently as 2017 Argentina — yes that’s seven-time defaulter, Call-me-“Lucky” Argentina — was selling bonds with a 100 year maturity. Less than a year later, it asked the IMF for a USD30bn bailout.
