What a sovereign rating is — and what it means for Romania

olivLaw Psychohistory

What it is and what it is not

A sovereign rating is an agency's opinion of a state's ability and willingness to pay its debts on time. The word “opinion” matters: S&P states that ratings concern relative credit risk, are forward-looking and are not guarantees. Nor are they a grade for the government, or a recommendation to buy bonds. The most closely followed agencies are S&P Global Ratings, Moody's and Fitch.

The scale and the line that matters

ZoneS&P and FitchMoody's
Very high qualityAAA, AAAaa, Aa
Upper mediumAA
Lowest investment-grade rungsBBB+, BBB, BBB-Baa1, Baa2, Baa3
Speculative grade (“junk”)BB+ and belowBa1 and below

The line runs between BBB- and BB+ (at Moody's, Baa3 and Ba1). Beside the grade sits the outlook: positive, stable or negative. At S&P, it shows the likely direction over a horizon typically of six months to two years. A negative outlook is a warning, not a downgrade.

In the European Union, Article 8a of the rating agencies regulation requires an annual calendar, published at the end of December, with dates set on a Friday. Deviations must be justified. That is why decisions usually appear on Friday evenings.

How agencies decide

A rating is not a public formula, but it can largely be explained. Cantor and Packer (1996) examined 49 countries and eight variables, among them per capita income, economic growth, inflation, external debt, level of development and default history. The regression explained over 90% of the differences between countries, with an error of about 1.2 notches. They also show that the market broadly shares the same ranking of risk, and that rating announcements have an immediate price effect on bonds below investment grade.

Why it matters: the mechanism

From public finances to the cost of borrowing1Large deficits andrising debt2The agency changes theoutlook or grade3Some rules and mandatesdepend on the grade4Investors demand ahigher yield5The state pays more onits debt6Less money remains forother spending
The simplified chain. The order is not fixed: the market may demand higher yields before the agency decides.

The links are not equally strong. The rules are documented: the IMF showed in 2010 that ratings are embedded in regulation, in the collateral central banks accept and in private contracts. The European Central Bank, for example, requires at least credit quality step 3 for collateral, which reaches down to BBB- and Baa3. The effect on yields is measured: the IMF also found that moving from investment to speculative grade significantly widens the yield spread. The size of the effect is uncertain, however, because the market anticipates. Ahead of the October 2026 decision, Reuters noted that five-year default insurance on Romania had been priced for a two-notch downgrade to BB since the start of 2025.

The effect does not stop at the state: the country's rating often serves as a reference for large local banks and companies. In December 2025, for example, Fitch rated Banca Transilvania BBB- with a negative outlook, in line with the state.

What a downgrade does not mean

  • It is not a default. A lower grade describes a higher risk, not an unpaid debt.
  • It is not necessarily a surprise. Much of it may already be in the price.
  • It is not irreversible. Romania has been through it: S&P and Fitch cut it to speculative grade in autumn 2008, Moody's kept it at investment grade, and the return came from Fitch in July 2011 and from S&P in May 2014.

The reasons are fiscal and external. The deficit was 9.3% of GDP in 2024 and 7.9% in 2025, the largest in the EU, and government debt reached 59.3% of GDP. S&P forecasts a deficit of 6.25% in 2026, 5.8% in 2027 and 5.0% in 2028, a current account deficit of 7.5% of GDP in 2026 and an interest bill rising from slightly above 2.0% of GDP in 2024 to 3.2% in 2026 and 3.5% in 2028. The 10-year yield was about 7.4%, above the average effective rate of 5.6% estimated for the end of 2025: as old debt is refinanced, the average cost tends to rise. These are the agency's estimates, not certainties.

S&P has also said what would change its opinion. It could downgrade if the protracted government formation, after the coalition collapsed in May 2026, hinders deficit reduction in 2027 and 2028, or if external pressures intensify. It could move to a stable outlook if the fiscal and external deficits narrow, with a credible medium-term plan.
