A sovereign with its own printing press almost never defaults in local currency. The same sovereign borrowing in dollars can default tomorrow. Credit analysis of governments hinges on currency, willingness, and tax base, not just the balance sheet.
A sovereign is a national government. Two questions drive the rating: can it pay (ability) and will it pay (willingness). Both must hold. A wealthy country that decides default is politically cheaper than austerity becomes a credit risk regardless of tax base.
KEY: Sovereign default is often a choice, not an accident. Argentina has restructured nine times since 1816 despite holding real assets and tax authority. Ability is necessary but not sufficient.
Local currency vs. foreign currency. A sovereign borrowing in its own currency controls the printing press through its central bank. It can always create nominal cash to service debt, though inflation is the cost. Borrowing in foreign currency (typically USD or EUR), it cannot print and must earn or borrow the currency. Rating agencies therefore assign a separate, lower rating to foreign-currency sovereign debt.
Common mistakes
- Assuming local and foreign currency ratings should match. They almost never do for emerging markets. The lower rating belongs to foreign currency. Trap: "the issuer is the same, so the rating must be the same."
- Treating GO and revenue bonds as interchangeable. GO = full taxing power. Revenue = project cash flows only. Trap: applying DSCR to a GO bond or debt-per-capita to a revenue bond.
- Ignoring willingness to pay. A sovereign with capacity may still default for political reasons. Trap: ranking sovereigns purely on debt/GDP without considering institutional strength.
Bottom line
- Local-currency sovereign debt is rated higher than foreign-currency debt of the same issuer because the sovereign can print its own currency
- Five sovereign qualitative pillars: institutional, political, economic, fiscal flexibility, monetary flexibility
- Key sovereign quantitative metrics: debt/GDP, deficit/GDP, interest/revenue, current account, and reserves/short-term external debt
- General obligation (GO) bonds are backed by the full taxing power of the issuer. Revenue bonds are backed only by project cash flows
Exam shortcut
When two ratings exist for one sovereign, the higher one is local currency. For municipal questions, classify the bond first (GO or revenue) before reaching for any metric: GO triggers tax-base analysis, revenue triggers DSCR. Memorize DSCR thresholds as a ladder: below 1.0x is shortfall, 1.0 to 1.25x is thin, 1.5x and above is investment-grade comfort.
