IDA21: What It Gets Right and What It Doesn’t Fix
Architecture, Advances, and Structural Gaps in the $100 Billion Replenishment
$100bnIDA21 total commitment authority, FY2026–2028. Largest in IDA history. 8% nominal increase over IDA20’s $93bn.
$8.8bnFCV Envelope: PRA, RECA, TAA — three-tier architecture for prevention, conflict engagement, and turnaround.
$3.2bnPrivate Sector Window for IFC/MIGA deployment. IDA18–20 PSW did not produce net increase in IFC FCS commitments.
25Strategic Policy Commitments. Reduced from 1,000+ in IDA20. Zero specific PCs on Quality at Entry, supervision, or Bank performance in FCS.
What IDA21 Is
The 21st Replenishment of IDA, approved by the Board of Governors on 17 March 2025 and effective from 1 July 2025, commits up to $100 billion in total commitment authority for FY2026–2028. The overarching theme is ‘Ending Poverty on a Livable Planet.’ IDA’s hybrid financing model mobilises approximately $3.50 of commitment authority per $1.00 of Donor grant contribution; more than 70 percent of IDA20 resources came from non-Donor sources.
| Window / Allocation | Size | Key Features |
|---|---|---|
| Country Allocations (PBA) | $58.1bn | 65% of concessional resources; performance-based; simplified composite terms |
| FCV Envelope | $8.8bn | PRA (prevention), RECA (conflict), TAA (turnaround); enhanced grant flexibility for CPIA ≤2.5 |
| GROW Window (new) | $15.9bn | Replaces Regional Window; ring-fenced WHR sub-window ($2.4bn); fully concessional |
| Scale-Up Window | $10.0bn | $7.0bn non-concessional + $3.0bn concessional SML; expanded eligibility |
| Crisis Response Window | $3.7bn | Last-resort financing; $1.0bn early response facility; grant terms for red-light countries |
| Private Sector Window | $3.2bn | IFC/MIGA deployment; new public dashboard; + $0.5bn IFC Concessional Capital Window |
| IDA-GFPP (new) | $0.3bn | Project preparation grants; up to $100m/year |
| Total Commitment Authority | $100bn | 8% increase on IDA20; grant element $53bn (54%) |
What IDA21 Gets Right
FCV Classification AdvanceThe new FCV classification framework — distinguishing prevention, high-intensity conflict, and turnaround settings — is a genuine advance over blunt FCS designation. It enables differentiated engagement aligned with actual country context.
Project Preparation FundingThe IDA-GFPP ($0.3bn, up to $100m/year) directly addresses a documented constraint: 43% of client country officials cited lack of project preparation funding as a barrier to quality project design. This is the correct upstream intervention.
FCS Scorecard DisaggregationThe WBG Scorecard introduces 22 outcome indicators disaggregated by FCS status for the first time. This is a meaningful transparency commitment that creates a baseline for accountability.
Third-Party Implementation for RECAManagement discretion to provide grants for third-party implementation in RECA countries with CPIA ≤2.5 is a meaningful operational improvement. Somalia’s model — 67% S+ in active conflict — demonstrates the template.
Facetime IndexThe Facetime Index tracking staff presence in FCS countries is introduced in the OEE Dashboard. Staff presence is a known predictor of supervision quality. Measuring it is the first step toward improving it.
The Structural Gaps: What IDA21 Does Not Fix
No Operational Policy Commitments on Delivery Quality in FCSIDA21’s single FCV-specific Policy Commitment (PC14) requires CPFs and Engagement Notes to include strategic objectives addressing FCV drivers. This is a planning-stage commitment about document content, not an operational commitment about delivery quality. IDA21 contains no specific PC for Quality at Entry in FCS, disbursement rates in FCS, or project restructuring practice in FCS — the three dimensions where IEG evidence most clearly identifies failure. This creates a two-to-three year window in which the institution will approve FCS projects without the operational commitments the evidence already warrants. The first gate is the IDA21 MTR, not scheduled until approximately mid-FY28.
PSW Additionality: Not Resolved by Governance RestructuringIDA21 restructures PSW governance from a retail model (dual Board approval of individual transactions) to a wholesale model (IDA Deputies approve overall allocation; IFC/MIGA Boards approve individual transactions). This reduces transaction costs but does not address the additionality problem: non-PSW IFC own-account commitments in PSW-eligible countries actually fell during IDA18–IDA20, and private capital mobilisation per dollar of IFC commitment was lower in PSW-supported projects than in non-PSW projects. The wholesale model, by reducing IDA Board visibility into individual transactions, may further weaken the external accountability mechanism intended to prevent PSW substitution.
RECA Reach: A Mechanism That Has Not Reached Its Intended BeneficiariesRECA was applied to only two countries across IDA19 and IDA20: South Sudan and Yemen. The cap increase to $400m per cycle is a calibration, not a redesign. The structural problem is that RECA eligibility requires states to maintain annual reviews and engage through government channels — a requirement unworkable in zero-capacity contexts such as Afghanistan after 2021, Sudan after 2023, or Haiti. The third-party implementation discretion is a meaningful improvement but has not yet been converted to a standard modality with provider accountability standards and transition pathways.
Accountability AsymmetryIDA21’s Sustainable Development Finance Policy holds borrowing governments accountable for their policy performance through the PBA mechanism. No equivalent accountability mechanism holds the Bank’s own teams accountable for Quality at Entry, supervision quality, or development outcome rates. The Denizer-Kaufmann-Kraay finding — that 80% of outcome variation is attributable to Bank-level decisions — makes this asymmetry the central governance gap of the replenishment architecture. IDA21 is a framework that enforces accountability on one party to the development relationship and ignores it on the other.
