Public Finance and Sovereign Debt
The Global Risks Alliance (GRA)
Regions, provinces and cities deliver much public spending and in many countries borrow. Their fiscal position depends on transfers from the centre, own revenue and rules on borrowing. Expectations of central bailouts can encourage overborrowing. This page sets out how subnational fiscal risk develops and reaches the national budget, how it is measured, and who decides.

Layers and dates
Subnational fiscal risk is the risk that regions, provinces and cities overspend or overborrow, and that their problems reach the national budget. It is shaped by transfers, own revenue, borrowing rules and expectations of central bailouts. Central and subnational governments, lenders and legislatures hold the decisions.
The working screen behind this subject: its structure, terms and states. Names are placeholders and values illustrative.
Local and provincial budget shocks. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Subnational governments often spend more than they raise, relying on transfers. Cuts or delays in transfers squeeze services and push them to borrow.
If lenders and local leaders expect the centre to rescue a struggling region, they lend and borrow more freely, and the centre's debt absorbs the cost.
Local government financing vehicles and municipal enterprises borrow outside fiscal rules, accumulating debt that may not appear in official figures.
Borrowing limits, balanced budget rules and market discipline restrain subnational debt to different degrees. Enforcement and data decide their effect.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Fiscal decentralisation | The assignment of revenue and spending responsibilities to lower levels of government. |
| Soft budget constraint | A situation where a government entity expects to be rescued if it overspends, weakening discipline. |
| Intergovernmental transfer | Funds passed from a higher level of government to a lower one. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |

| Subnational government debt | percent of GDP | annual | Government finance statistics | OFFICIAL |
| Transfers as share of subnational revenue | percent | annual | Government finance statistics | OFFICIAL |
| Subnational borrowing rules | categorical | on change | Legislation and OECD databases | OFFICIAL |

The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Subnational governments rely on their own taxes, transfers from central government and borrowing. Their revenue bases are often narrow and tied to local economic conditions, property values or specific industries. Disasters hit local budgets directly through damage to public assets and lost revenue. When central governments face fiscal stress, transfers to local governments are often cut, transmitting stress downwards.
The expectation of central government support creates moral hazard: if lenders and local governments expect a rescue, they may borrow too much. Many countries regulate subnational borrowing through fiscal rules, approval requirements or market discipline. Subnational debt, including that of local government financing vehicles in some systems, can be a significant and sometimes hidden source of national fiscal risk.
Assessing revenue bases, spending needs and borrowing capacity, using economics and development economics.
Testing local budgets against disaster and economic scenarios, using scenario design and stress testing.
Comparing intergovernmental fiscal arrangements and borrowing rules.
Subnational data is often incomplete or inconsistent, arrangements vary greatly, and implicit central support is hard to measure.
