Why Public Financial Management Matters

PFM FoundationsLesson 3 of 8 · 6 min read

Public spending has grown — and so has the risk

As financial operations have grown large and complex, many countries end up running some spending “off-budget” — through state-owned enterprises, public-private partnerships, or separate development budgets — rather than entirely through the core annual budget. The larger and more complex the machinery, the more that can go unseen.

Three reasons PFM matters

Why PFM matters

  1. 1

    Sustainability

    PFM helps ensure today's fiscal choices don't unfairly burden future generations. Long-horizon issues — climate change, an ageing population — need to be addressed early, otherwise mitigation costs or pension costs become unaffordable later. Sound institutions are part of delivering on long-term goals.

  2. 2

    Resource allocation / fiscal space

    PFM provides the setting in which government creates and manages fiscal space — room to fund new priorities. It ensures new initiatives are properly analysed and prioritised, and that new spending is sustainable rather than financed purely through rising debt.

  3. 3

    Oversight, transparency, and trust

    PFM makes government ultimately accountable for its choices. Citizens, businesses, and investors all want reassurance that public money is used effectively and in line with agreed goals — building trust that supports productive, efficient, and inclusive economic activity.

Knowledge check

A government wants to launch a large new welfare programme but hasn't checked whether it can be financed without a permanent rise in debt. Which PFM reason for mattering is most directly at risk?

Key takeaways

  • Public spending is now a very large share of national income almost everywhere — the stakes for good PFM are high.
  • Complex financial operations create room for off-budget spending that escapes normal scrutiny.
  • Even advanced economies have been caught out by an inaccurate picture of their own finances — this is a universal risk.
  • PFM matters for three reasons: sustainability, fiscal space, and oversight/transparency/trust.

Frequently asked questions

What is 'off-budget' spending?

Spending or financial activity conducted outside the formal annual budget process — for example, through state-owned enterprises, public-private partnerships, or separate development budgets.

What is 'fiscal space'?

The capacity to finance additional or new public spending — through increased resources and/or reallocating existing spending — without threatening debt sustainability.

Why does PFM matter even in advanced, wealthy economies?

Because the risk of an inaccurate or misleading picture of government finances isn't limited to lower-income countries — even advanced economies have discovered gaps in their own understanding of their finances during a crisis.
