2b · Fairness & disparate-impact check (anti-redlining control)

Two lenses. CONCENTRATION shows where High+ risk clusters (can be legitimate geography). PROPORTIONALITY flags localities repriced HARDER than their measured risk warrants (repricing intensity ≥ 1.5× the system's) — the actual disparate-impact question. Every high-risk asset routes to adaptation structuring (never a location denial); price-based exclusion remains the bank's market-conduct responsibility.

2 localities repriced disproportionately to measured risk (repricing intensity ≥ 1.5× the book's 42.85 average) — the disparate-impact signal to review.

3 · Hazard exposure across the book

Number of assets at High or Critical for each hazard. An asset exposed to several hazards is counted under each, so these counts (and the per-hazard exposures elsewhere) can overlap and sum above the portfolio total — they are not a partition.

4 · Financial impact — physical damage, collateral & climate ECL

Two channels, kept separate. (1) Physical damage — an Average Annual Loss (AAL) per hazard from a depth-damage × frequency proxy: GHS 904k/yr of expected (mostly uninsured) damage. (2) Market repricing — a forward collateral devaluation that raises stressed LTV and loss-given-default, driving GHS 9.82M of potential collateral shortfall and an GHS 96k/yr indicative climate ECL uplift. A single severe event in Ashanti could cause GHS 465k of correlated, simultaneous loss.

⚠ Indicative annual marginal overlay — not a lifetime/12-month staged IFRS 9 ECL, not a valuation, not the bank's PD/LGD model. All parameters (AAL, repricing, downturn LGD, PD, ~90% uninsured) are illustrative and exposed for calibration — see §Methodology and the gap register.

5 · Forward-looking scenario projection (IPCC AR6)

How the share of exposure at High+ risk migrates over time under SSP2-4.5 — Middle of the road. Each hazard is intensified by an AR6-grounded factor (Rx1day rainfall, hot-day count, consecutive dry days, sea-level rise) and applied to today's score with a bounded saturating projection — a screening estimate, not a downscaled climate forecast. The interactive dashboard lets the user switch between the SSP1-2.6 / SSP2-4.5 / SSP5-8.5 pathways and 2030–2100, and pull any single asset through all three.

9 · Gap register — what this screen does not replace

6 of 12 items are reliance-blocking. PortfolioCheck is screening-grade triage that flags collateral for closer review — it complements the bank's credit process; it does not certify it.

#AreaWhat is requiredOwnerSeverity
G01 Property valuation Climate haircuts are applied to an implied collateral value, not a surveyed valuation. The bank's valuation must confirm property values. Bank credit / valuation BLOCKING
G02 PD / LGD models ECL figures use illustrative default PD/LGD parameters. The bank must substitute its own IFRS 9 term-structure and recovery model. Bank risk modelling BLOCKING
G03 Building-level resilience Finished-floor elevation, flood defences and construction quality are not observed unless the bank records completed adaptation measures per asset; absent that, resilience is assumed unmitigated. Survey / site inspection BLOCKING
G04 Adaptation evidence Recorded adaptation measures that reduce an asset's risk are SELF-REPORTED until accepted by the supervisor; they receive no regulatory credit until taken in full once the bank holds evidence (site inspection / as-built / maintenance covenant). The bank must hold that evidence before relying on the reduced figures in a regulatory return. Bank / site verification BLOCKING
G05 Insurance status Whether each property carries valid flood/peril cover is a key loss mitigant and is not in the book; confirm per asset. Bank / borrower records BLOCKING
G06 Governance & disclosure Board oversight, the bank's own footprint and the formal disclosure statement are governance items this screen cannot produce. Bank governance BLOCKING
G07 Scenario calibration Forward views use IPCC AR6 SSP intensification factors applied with a bounded saturating map — screening estimates, not downscaled climate projections. Confirm the pathway and horizon assumptions before external disclosure. Climate science / consultant Advisory
G08 Transition risk out of scope This screen covers PHYSICAL climate risk only. The BoG Directive also requires transition risk (policy, carbon, stranded-asset) — material for a mortgage book mainly via energy-efficiency repricing; assess separately. Bank / consultant Advisory
G09 Nature / biodiversity (TNFD) out of scope This screen covers PHYSICAL CLIMATE risk only. Nature-related financial risk (TNFD dependencies & impacts) is deliberately out of scope; the Land hazard is a proximity screen (Ramsar/protected/contamination), NOT a nature dependency/impact assessment. Assess via a TNFD-aligned process. Bank / consultant Advisory
G10 Social / inclusion & just transition Financial-inclusion, gender and just-transition dimensions (SBP P3/P4; IFC SBFN) are out of scope of a physical-collateral screen. The tool's anti-redlining safeguard keeps credit flowing to exposed communities via a financeable fix (never a location denial), but inclusion is assessed by the bank. Bank / SBP programme Advisory
G11 Price-based exclusion (market conduct) The origination safeguard prevents a location DENIAL, but risk-based repricing/ECL can still price a poor flood-zone borrower out. Price-based exclusion is a market-CONDUCT matter the bank must govern (affordability, conduct rules); the tool flags it but does not cap pricing. Bank market-conduct / BoG conduct Advisory
G12 Refer-resolution audit A high-risk 'Refer for adaptation structuring' hands off to a credit officer who could still decline. The bank must LOG each refer's resolution (offer made / adaptation loan structured / declined-with-reason) and report the split so the anti-redlining safeguard is auditable, not just a suggestion. Bank credit workflow Advisory

Methodology (screening-grade)

Vulnerability. Composite = 50% weighted hazard load (Flood 34% · Coastal / sea-level 18% · Extreme heat 16% · Riparian proximity 12% · Land / contamination 10% · Drought / water stress 10%) + 50% of the single worst hazard, so one extreme hazard that can impair the security is not averaged away (bands: Low <25 · Moderate 25–50 · High 50–75 · Critical ≥75). A single-peril severity floor completes the blend: a worst hazard ≥0.85 (e.g. an observed Sentinel-1 flood) floors the composite at Critical, and ≥0.70 at High, so a near-certain peril carries the asset even when the other hazards are low. Each hazard is scored 0–1 by the built-in analyser (Ghana location model) and, with the live engine overlay mode, overlaid with SafeGround (flood / river / coastal / land) and FloodGuard (flood susceptibility), FloodGuard felt-heat (ERA5) and NASA POWER rainfall climatology (drought / water-stress).

Hazard → money (two channels). (1) Physical damage — an Average Annual Loss (AAL) per hazard = max-AAL × score1.5 (building-collateral ceilings: flood 5%; financially supported coastal risk 5.5%). Riparian proximity is represented through flood to avoid double counting; heat, land and drought remain due-diligence scores without a standalone building-damage AAL until a case-specific impairment model is supplied. Hazard AALs are combined across hazards; damage is assumed mostly uninsured in Ghana (~90% assumed — penetration is very low, so the loss falls on the collateral). (2) Market repricing — a forward collateral devaluation = ~35% of the capitalised AAL (cap rate 9%) + an insurability premium, capped at 40%; this raises the stressed LTV. ECL = PD × LGD × EAD (indicative annual marginal): LGD from realisable collateral with a smooth downturn liquidation, floored at 5% (Basel-style, so no LTV kink); PD = 2% base, rising with negative equity (strategic default) and uninsured damage. Not a lifetime/12-month staged IFRS 9 ECL, not a valuation. The single-event figure is a correlated-tail proxy (one severe event hitting all High+ assets in a region at once). Data quality is flagged on the PCAF 1–5 scale (screening is never better than 3). Scenario multipliers are illustrative — anchor to IPCC AR6 SLR / NGFS before disclosure. All parameters are exposed for recalibration against the bank's own loss experience.
