Medium-term expenditure frameworks (MTEFs) are an important tool for overcoming the limitations of the annual budget cycle by adopting a medium-term perspective for achieving government fiscal objectives. They generally span a period of at least three years beyond the current budget. MTEFs are typically defined by combining expenditure ceilings and a baseline estimation of government policies’ costs that are continually updated.
MTEFs improve budget formulation by encouraging the development of spending plans on the basis of existing resources and by promoting fiscal discipline. By incorporating a medium-term perspective in the budget process, they allow for a more efficient resource allocation aligned with the government’s goals, and they link the annual budget to multi-year policies. Moreover, MTEFs can increase budget stability by decreasing uncertainty in the financial flows for ministries and agencies, affording time to adjust and plan their operations accordingly.
A major challenge in implementing successful MTEFs is ensuring that expenditure estimates and ceilings are based on high-quality projections. Active co-ordination with line ministries and sub-national governments, both of which account for large amounts of government expenditure is also required.
More than two-third of SEA countries (70%), and nearly all OECD countries (91%), have established a medium-term expenditure framework. Their legal foundation may be an important factor in determining the effectiveness of MTEFs: it is illustrated by the degree to which they are stipulated in legislation, decided by the executive or the legislative, and subsequently monitored by the legislative or independent bodies. For example, having an MTEF defined in a law may enhance effectiveness as it opens it to greater accountability and transparency.
Of ten SEA countries, only Indonesia, Thailand and Viet Nam have laws detailing the existence of an MTEF or of budget ceilings at some level of expenditure. For OECD countries this applies in 72% of cases (24 countries out of 33). Similarly to OECD countries in the SEA region, ceilings range mainly from 3 to 5 years. Unlike OECD countries (66%), only 30% of SEA countries have ceilings in place for total expenditures, with most countries focusing instead on organisational expenditures per ministry level or other. Only Viet Nam has ceilings in place for programme or sector expenditures.
