A Quick Note on Monetary Sovereignty (Before Part 2)
What I mean when I say a country “controls its own balance sheet”.
Before moving to Part 2 of the series, a quick clarification.
I use the term monetary sovereignty in a very specific, mechanical sense – not ideological, not theoretical, not “print money forever”.
It means one thing:
Does the government issue the currency it borrows in?
Everything follows from that.
If the answer is yes, then mechanically:
it cannot run out of its own currency
it can always roll over its own-currency debt
a bond market panic cannot force default (it can cause inflation, but not insolvency)
the central bank and treasury together form a closed system
Countries in this category: Japan, United States, United Kingdom, Australia, Canada.
Their risk comes from inflation constraints, political constraints, and real-resource constraints – not from an inability to finance themselves.
If the answer is no, then:
the state borrows in a currency it cannot create
it is exposed to funding stops
it needs external investors or foreign central banks to roll debt
default becomes a real possibility even with moderate debt levels
Countries in this category: Eurozone members (Greece, Italy, France, Germany), and most countries that borrow heavily in USD or EUR (Turkey, Indonesia, Brazil, South Africa).
This is the first gate in the model I’m building: Sovereign Balance-Sheet Capacity (SBC).
It tells you how much room a state actually has before external finance becomes a binding constraint.
It does not tell you everything – but without understanding this first step, nothing else about sovereign risk makes sense.
Part 2 (the domestic foundations) will make a lot more sense with this definition in place.
