The problem
Strong PFM assessments do not guarantee operational responsiveness in a crisis
Governments can have financing in place, score well on public financial management (PFM) assessments, and still struggle to move resources quickly when a shock hits. Plans, allocations, and institutional frameworks are necessary — but they are not the same as the ability to get money from spending authority to community level under pressure.
The gap between institutional readiness and verified, time-bounded ability to move resources under pressure is real, recurring, and largely unmeasured by existing tools. It is the gap that Fiscal Hydraulics is designed to make visible and verifiable.
"When disaster strikes, we have to cobble together funds for a relief and reconstruction package.... The entire fiscal landscape gets affected.... [W]hen towns and farms get flooded, our revenue base gets submerged, and our tax collection goes under too."
Ralph G. Recto, Secretary of Finance (Philippines), remarks at the launch of the 2024 PEFA++ and DRR-PFM assessment reports (Department of Finance, 2025).
Secretary Recto's observation comes from a country that had just received a high rating on a PFM crisis-readiness assessment. It points to a structural problem: strong institutional readiness does not necessarily translate into operational responsiveness.

Trigger → Track → Transit: speed and ease of flow
Use
Diagnose binding constraints on crisis finance flow
Outputs
Flow map + constraint hypothesis + proof pack
How it fits
System flow readiness diagnostic — complements both
Fiscal Hydraulics is not a replacement for PEFA or DRR-PFM. It addresses a dimension they were not designed to cover: how fast resources flow through the network in a crisis, and where bottlenecks are likely to form (given the evidence set). Outputs are evidence-bounded hypotheses with explicit coverage and data gaps, designed to guide validation rather than substitute for audit or transaction testing.
Who this is for
IFI and bilateral donors
Where it fits
Pre-investment screening for crisis finance, DRF, and PFM programmes — and scoping before committing TA or larger instruments.
How it is used
Commission a System Scan for rapid country-level screening, or a System Diagnostic where you need a more defensible evidence base before committing to a direction.
What it provides
A faster, more consistent basis for country comparison — and a clearer starting point for targeting TA or follow-up analysis.
Finance ministries and counterparts
Where it fits
In readiness planning, reform sequencing, and cross-agency review — before a shock forces the diagnosis under pressure.
How it is used
Use a System Diagnostic to build the evidence base, then run a facilitated Map Workshop to align ministries, agencies, and counterparts on priority constraints and next steps.
What it provides
A shared, documented baseline that focuses reform effort on the most likely weak points and gives institutions a common starting point for action.
Risk financing facilities and insurers
Where it fits
Between instrument design and deployment planning — where payout speed matters but downstream fiscal routing has not yet been stress-tested.
How it is used
Commission a System Scan for a rapid first read, or a System Diagnostic where you need stronger evidence and a more defensible basis for country dialogue and instrument design decisions.
What it provides
A clearer view of whether instruments are operationally backed by the systems they rely on — and a structured basis for country dialogue and instrument refinement.
Climate finance providers
Where it fits
At country readiness, accreditation, and programme design stage — where approved or committed funds still depend on domestic fiscal systems to reach execution.
How it is used
Use a System Scan for initial country screening, or a System Diagnostic where the stakes of getting delivery assumptions wrong are higher and you need a more defensible evidence base before programme design commits.
What it provides
An evidence-based view of where delivery risk sits in the system — and a more grounded starting point for readiness support, country dialogue, and programme design.
Development consultancies and implementation partners
Where it fits
Within assignments on public finance reform, resilience, climate finance, decentralised delivery, anticipatory action, shock-responsive social protection, or crisis readiness.
How it is used
Integrate a System Diagnostic as a complementary screening module within an existing scope, or run a Map Workshop to align client and counterpart stakeholders on fiscal flow constraints at assignment outset.
What it provides
A more consistent way to structure early analysis, more repeatable reporting, and a clearer basis for scoping and follow-up.
Research institutions and policy analysts
Where it fits
Where institutional analysis needs a structured, replicable method for examining how finance actually moves through fiscal systems — rather than how systems are designed to work.
How it is used
Apply a System Diagnostic as the primary data-collection instrument for single-country or comparative analysis; use a Map Workshop to validate hypotheses with government and institutional stakeholders.
What it provides
A consistent analytical framework, structured evidence extraction, and a documented hypothesis set that supports comparison across countries and contexts.
Start with the right level of evidence
Each product can be commissioned independently or in combination. A System Scan or System Diagnostic is often the starting point; a Map Workshop can run alongside or follow either.
System Scan
Rapid first-screen
Start here if —
You need a quick, evidence-bounded baseline before commissioning deeper work. Public-source based.
System Diagnostic
Validated assessment
Start here if —
You need a document-verified analysis with an evidence register and stronger confidence signalling.
Map Workshop
Stakeholder alignment
Start here if —
You need to bring counterparts together to map and validate the pathway, agree priority constraints, and assign follow-up evidence actions.
