At its core, public financial management (PFM) is about achieving fiscal discipline and strategic resource allocation. The Medium-Term Fiscal Framework (MTFF) and the Medium-Term Expenditure Framework (MTEF) are the two main instruments that make it possible, working in tandem to promote fiscal stability and sustainability. At a recent workshop organized by the IMF’s Caribbean Technical Assistance Center (CARTAC), participants explored the components underpinning these frameworks, highlighting the Caribbean region's distinct fiscal realities and policy challenges.

The MTFF sets the rhythm. It defines the fiscal envelope—how much revenue, expenditure, deficit, and debt a country can sustain over a three-to-five-year horizon, expressed through targets such as the primary balance and the debt-to-GDP ratio. Anchored in macroeconomic forecasts, it helps governments stay in step with evolving economic conditions while remaining mindful of the risks and external shocks that could throw them off balance.
Grenada and Saint Lucia illustrate how the MTFF sets the fiscal rhythm in practice. In Grenada, the MTFF is prepared ahead of the annual budget and is grounded in the Public Finance Management Act and the Fiscal Resilience Act, 2023, which establish key primary balance and debt targets. Its structure links the macroeconomic and social context, medium-term fiscal objectives and forecasts, compliance with fiscal rules, and fiscal risk management. Saint Lucia follows a similar approach under its Public Finance Management Act, using the Fiscal and Budget Survey to define the Government’s medium-term priorities, fiscal targets, and budget strategy, and the Fiscal Policy Statement to assess mid-year budget performance and emerging risks. Together, these examples show how an effective MTFF translates legal mandates and macro-fiscal analysis into a disciplined, forward-looking fiscal path.
If the MTFF provides the rhythm, the MTEF brings it to life. The fiscal envelope established in the MTFF sets the expenditure ceilings within which sectoral and programme allocations are made the MTEF, giving ministries predictable, multi-year resource allocations aligned with policy priorities and available fiscal space. The result is a stronger link between fiscal policy and the annual budget, allowing ministries to plan with greater certainty.
Like a Tango, the MTFF and MTEF move through a rhythm of push and pull. When fiscal targets tighten, expenditure plans must yield; when political priorities press forward, fiscal discipline must hold its ground. Their coordination is not static but dynamic, built on tension, trust, and timing. Balance is achieved not through rigidity but through contextual responsiveness, allowing governments to deploy measures such as countercyclical policies or cost of living adjustments, as recently demonstrated in St. Vincent and the Grenadines. It is the art of moving together without losing step.

The relationship between the two frameworks becomes more evident in practice. For example, a projected fishing contraction that lowers the revenue forecast at the MTFF stage tightens the resources available to line ministries at the MTEF stage. When they fall out of step—when fiscal targets shift unpredictably or expenditure plans ignore macro constraints—the performance falters. Climate-related disaster such as Hurricane Beryl in St. Vincent and the Grenadines and Hurricane Melissa in Jamaica, commodity price shocks, or global pandemics such as COVID-19 can each disrupt the sequence: if ceilings are not revisited as the outlook changes, expenditure plans become overcommitted, forcing difficult spending cuts, additional borrowing or the accumulation of arrears that ultimately undermine the budget credibility these frameworks are designed to protect.
Success depends on coordination and communication. Each push and pull reflects the delicate negotiation between fiscal discipline and strategic priorities, while their synchronized dance ensures that they are not competing forces, but complementary steps. When the two are in sync, they can produce credible budgets, sustainable policies, and enable institutions to plan beyond the annual cycle. With the macro-fiscal unit, budget office, and policymakers moving together, the frameworks strengthen resilience, credibility, and trust in governance, supporting sustainable economic growth.
For small, shock-prone economies in the Caribbean, the Tango between the MTFF and MTEF is not a performance for entertainment but one for survival. There is little room for fiscal missteps or for falling out of step with the rhythm. Poor policy decisions have placed countries on unsustainable fiscal paths, weakening growth prospects. Recent shocks have shown how quickly fiscal assumptions can change, reinforcing the value of strong medium-term fiscal and expenditure frameworks. Ultimately, the lead choreographers - the policymakers - must take ownership of the performance, ensuring that fiscal decisions remain firmly grounded in the rhythm and discipline of the MTFF and the MTEF.
In this dance, elegance is secondary; what matters is the ability to stay in rhythm, maintain balance through tension, and to move together toward stability and prosperity. While many Caribbean economies have stumbled under the weight of high debt burdens and subdued economic growth, there remains an opportunity to master the steps of this tango and bring it to a confident final pose.
