FI 15 Credit Analysis for Government Issuers

Governments raise money in public debt markets for reasons that have little to do with why a company borrows. A corporation funds working capital and fixed assets in order to earn a profit, and it services that debt from operating cash flow. A government borrows to run fiscal policy and to cover budgetary needs: the provision of public goods and services such as infrastructure, health care, and education. Its debt is repaid mainly from taxes and other public revenue, which may take the form of fees, tariffs, and at times the earnings of state-owned enterprises.

Because a sovereign government can tax essentially all private economic activity inside its borders, its bonds usually rank as the safest credit of any borrower operating in that country. In the most advanced economies, sovereign debt is frequently treated as default risk-free. Sovereign bonds from emerging and frontier market governments are a different matter, and they carry meaningfully higher default risk. Sovereign defaults are not rare, and they tend to cluster around the period when a country is still moving from an emerging toward an advanced economy.

It helps to separate the three broad issuer families early, because the source of repayment defines each one.

One feature sets government debt apart at the legal level. Under the principle of sovereign immunity, national law limits the ability of investors to force a sovereign into bankruptcy or to seize and liquidate its assets, which is exactly the remedy a creditor would pursue against a defaulting company. Because that enforcement route is largely closed, a sovereign issuer must be judged not only on its ability to pay but also on its willingness to pay. When a government does run into trouble, the usual outcome is a negotiated restructuring, often with several lenders and a multilateral body such as the International Monetary Fund (IMF) at the table, that stretches out maturities or softens interest terms so investors can eventually recover their money.

To bring structure to all of this, analysts combine qualitative judgement with quantitative ratios. The qualitative side reads institutions, policy, and the shape of the economy; the quantitative side puts numbers on the debt load, growth, and external position. Non-sovereign issuers, such as regional governments and quasi-government agencies, borrow too, and their debt leans on local taxing power or the cash flow of a particular project. The rest of this lesson works through the sovereign framework first, then turns to non-sovereign issuers.

Investors gauge a sovereign issuer by the stability and predictability of its revenue, whether that revenue is enough to cover interest and principal, and how heavily the government leans on borrowing versus its other resources. The qualitative side of that assessment rests on five interlocking factors, each of which shapes how dependable the tax base and the policy environment are.

Government institutions and policy

This factor asks whether public institutions foster political and economic stability. On the economic side it covers the rule of law, enforcement of property rights, a culture that treats debt repayment as normal, transparency, consistent financial reporting, and the general ease of doing business. On the political side it covers the stability of domestic institutions and the absence of conflict with neighbors. Analysts often express these as a relative ranking or score. Willingness to pay sits inside this factor, for the reasons set out above.

Fiscal flexibility

Here the question is how well a government keeps fiscal discipline across the economic cycle. That runs from the enforceability of tax collection, through the prudent allocation of spending on public goods, to keeping the stock of debt sensible relative to the size of the economy. Analysts look at how the government has adjusted spending in past cycles and at the likely effect of announced policy changes.

Romania offers a clear illustration. In October 2021 Moody’s Investors Service shifted Romania’s sovereign outlook to stable from negative, holding the Baa3 issuer and senior unsecured rating in place. Alongside solid growth prospects, Moody’s pointed to an expectation of steady, sustained fiscal consolidation. As part of its path to full participation after joining the EU in 2007, Romania was expected to bring its annual deficit below 3% of GDP within three years, an incentive sharpened by the risk that EU structural and investment grants could be suspended if it failed to comply.

Monetary effectiveness

Monetary policy steers the quantity of money and credit. A central bank sets policy rates and reserve requirements and trades sovereign bonds through open market operations, all in the service of steady growth alongside low, stable inflation. What matters for credit is the degree of central bank independence. At one end the central bank acts almost entirely free of government influence; at the other it is little more than an agent of the treasury. Independence from the public treasury lowers the chance that a government simply monetizes its own debt, a move that would push domestic inflation up and drag the external value of the currency down.

Economic flexibility

The economic activity a government can tax is normally its main source of repayment, so analysts weigh not just the size of the economy and per capita income but also how diversified it is and how much room it has to grow. The strongest sovereign borrowers tend to sit on advanced, highly diversified economies with durable growth. Emerging and frontier economies often lean on a single industry or commodity, or trade with only a few partners, which leaves their tax revenue exposed to downturns, commodity price swings, and trade disruptions. A large informal economy or weak tax collection makes the problem worse.

External status

External status, sometimes called external governance, is about how a government’s trade, capital, and foreign exchange policies affect its capacity to service debt. The decisive question is whether the domestic currency is a reserve currency: one that is fully convertible and held in volume by overseas central banks and international investors as part of their reserves. When foreigners are willing to hold a country’s cash, bonds, and other assets in its own currency, the government can tap a far wider pool of lenders in that currency, which lowers default risk and lets it sustain larger structural deficits and a higher debt load. Many emerging and frontier countries face exchange controls, capital restrictions, or limited convertibility, which pushes them toward foreign currency borrowing or toward funding from bodies such as the IMF. Geopolitics can override the economics: after Russia invaded Ukraine in February 2022, the Republic of Moldova, sitting next to the conflict and absorbing an outsized inflow of refugees, saw inflation climb and growth stall, and in May 2022 it tapped an IMF extended credit facility to cover pressing external costs such as energy imports while pledging structural reforms to avert default.

In practice these factors overlap. A weak legal system, for instance, usually travels with a limited ability to collect taxes or enforce debt contracts. The following table gathers what analysts read under each heading.

Quantitative analysis tries to size the chance that an issuer can meet its fixed obligations. Sovereigns make this harder than companies do. Instead of audited statements under a common accounting standard, analysts work with government economic data that varies in quality and timing, does not compare cleanly across countries or across years, and is subject to revision and political pressure. Detailed public sector balance sheets are therefore of limited forecasting value, so the work is top-down and macroeconomic. A useful habit: for a sovereign ratio the numerator is often debt or periodic payments, as for a company, but the denominator is usually government revenue or GDP rather than sales or total assets, because those measure the economic activity available to tax.

Three quantitative pillars carry the analysis: fiscal strength, economic growth and stability, and external stability.

Fiscal strength

Fiscal strength turns on the current and expected debt burden and on how much the government relies on debt versus other resources. It splits into two ideas. Debt burden measures work like leverage and speak to solvency; a higher reading means weaker credit. Debt affordability measures work like coverage and show how easily interest is carried; here too a higher reading means weaker credit.

Analysts also track the annual fiscal surplus or deficit as a share of GDP to judge discipline and to see whether the debt burden is improving or drifting worse over time.

Economic growth and stability

Larger, wealthier economies absorb shocks better and sustain growth more easily, so the size of the economy (GDP) and per capita income both matter, as do the level and the variability of real growth.

The pairing of growth and volatility is what analysts really watch: a high average growth rate that is also steady points to a stronger credit profile than the same average delivered with wild swings.

A comparison of five Southeast Asian economies makes the point. Measured in purchasing power parity terms, Indonesia is the largest of the group while Malaysia is the smallest, yet Malaysia has by far the highest per capita GDP and a competitive, high-technology export base, which helped earn it the highest rating of the five (A3 from Moody’s, A from S&P). Vietnam is among the smallest with the second-lowest per capita GDP, but it grew fastest over the decade and was the only one of the five to expand in 2020; despite being the lowest rated (Ba3 from Moody’s, BB+ from S&P), its steady, high growth earned a positive outlook and an upgrade path from BB- to BB+.

External stability

External stability turns on whether foreign investors are both willing and able to keep their holdings denominated in the country’s currency. Where the currency is actively traded and held in reserve abroad, external stability is high. For a government whose currency is not a reserve currency, the key is external liquidity and solvency: the short- and long-term capacity to generate enough stable foreign currency inflows to cover interest and principal on external debt and other obligations to foreign investors.

These ratios weigh external debt against the resources that could repay it: GDP, foreign currency reserves, and foreign currency cash flows such as current account receipts. Current account surpluses and deficits from trade in goods and services offset capital flows in and out of the country. Some governments build reserves through a current account surplus with developed economies; others rely on remittances from citizens working abroad. Falling or volatile foreign currency balances weaken the capacity to service foreign currency debt, and where commodity exports supply most of the reserves, commodity demand and prices become primary credit drivers.

Sovereigns are the largest government borrowers, but they are not the only ones. Government agencies and regional governments also issue debt. For an agency, investors often face credit risk very close to the sovereign, either because a sovereign law created the entity and gave it borrowing powers (implicit backing) or because the government guarantees the debt outright (explicit backing). Sub-sovereign issuers that have their own taxing and revenue powers, such as a regional government, benefit from the sovereign’s economic and monetary framework because they sit within its jurisdiction, yet their creditworthiness can still diverge from the sovereign’s for reasons of their own.

Four issuer types make up most of the non-sovereign field.

Agencies, public banks, and supranationals

Agencies fulfill a government-sponsored mission and are usually authorized to borrow by the statute that created them, so investors assume a high likelihood of sovereign support and agencies often carry the sovereign rating. Airport Authority Hong Kong is a good case. It is a statutory corporation that the Hong Kong SAR government owns, and it operates Hong Kong International Airport, one of the busiest air-cargo gateways anywhere and a passenger hub reaching more than 200 destinations. In late 2020, after the pandemic gutted passenger volume, it launched a USD1.5 billion perpetual bond issue to fund a third runway and general purposes, split evenly between a 2.10% coupon callable after 5.5 years and a 2.40% coupon callable after 7.5 years. Both tranches were rated AA, one notch under the AA+ issuer rating, and that issuer rating was itself pinned to the Hong Kong SAR sovereign rating of AA+ on the expectation of state support should the authority face distress.

Government sector banks and development financing institutions work similarly. KfW, founded in 1948 and held 80% by the German federal government with the remaining 20% in the hands of the federal states, is the largest national development bank and benefits from an explicit statutory guarantee and institutional liability of the Federal Republic of Germany. Its bonds are rated AAA and are assigned a zero risk weight for bank capital purposes. KfW is also among the busiest green bond names in the international market: it sold its first such bond in 2013 and raised EUR16.2 billion this way in 2021 (about 20% of new debt), lifting cumulative green issuance to EUR47.1 billion by 2021, with proceeds channeled into renewable energy and energy efficiency.

Supranationals are owned by several sovereigns that join to pursue a common goal. The World Bank and its affiliate the International Bank for Reconstruction and Development lend for anti-poverty and sustainable growth projects; regional examples include the Asian Development Bank and the Development Bank of Latin America. Indonesia Infrastructure Finance shows the ownership pattern: set up in January 2010 with the Government of Indonesia holding 30%, the World Bank 20%, the Asian Development Bank 20%, KfW 15%, and Sumitomo Mitsui Banking Corporation 15%, it is rated BBB, level with the Indonesian sovereign, on its strategic role and the implicit support of its global development owners.

Regional governments: general obligation and revenue bonds

Regional government finance differs sharply across countries. In the Netherlands a public financial institution lends to municipalities within a structure that grants them the federal government’s rating; other countries share tax revenue across levels of government so local authorities can meet obligations. In the United States, by contrast, state and local issuers are rated individually and typically issue one of two bond types.

General obligation (GO) bonds are unsecured and backed by the general revenues and taxing authority of the issuing government. Their analysis overlaps with sovereign work (the ability to levy and collect taxes) but adds local questions: the strength of the business climate, the presence of major industries and employers that create a diversified and stable corporate tax base, any implicit national support, and the prudence of local budgeting. Crucially, a non-sovereign issuer commands only limited jurisdiction and holds no sway over national economic and monetary institutions, which leaves it more exposed to industrial decline and demographic shifts. Detroit is the cautionary tale: decades of shrinking auto employment and a shift of manufacturing to lower-wage states cut the city’s population from 2 million to 700,000, eroded the property and income tax base, and left a shortfall against roughly USD18 billion of debt. Detroit filed for Chapter 9 protection in 2013, the largest US municipal bankruptcy, and after a 17-month negotiation it emerged by selling and pledging assets, with pensioners keeping about 85% of benefits and holders of general obligation unlimited-tax bonds recovering 74 cents per dollar.

Revenue bonds finance a specific project, such as a sewer system, toll road, bridge, hospital, or sports arena, and they carry more risk than GO bonds because repayment leans on a single revenue stream. Their analysis blends project analysis (the need for the project, its projected use, and the economic base that supports it) with finances that resemble a corporate credit: operating performance, cash flow, liquidity, the capital structure, and how comfortably projected cash flow services the debt. The key measure is the debt service coverage ratio, the revenue left to cover principal and interest after operating expenses.
