A portfolio-scale physical-climate risk screen for a Ghanaian lender — every asset pinned and scored across flood, coastal, heat, riparian, land and drought hazards, ranked by vulnerability, concentrated geographically, and translated into a collateral-haircut and climate-ECL overlay with scenario horizons — structured for the Bank of Ghana Climate-Related Financial Risk Directive, the Ghana Sustainable Banking Principles and IFRS S2 / TCFD.
⚑ Wholly synthetic nationwide demonstration book. Public institution name used only as a navigation label; no bank or borrower data is represented.
This report screens Stanbic Bank Ghana Limited — 2026 H1 for Stanbic Bank Ghana Limited against physical-climate & environmental hazards, ranks every asset by vulnerability, maps the geographic concentration of risk, and translates the exposure into a collateral-haircut and climate-adjusted Expected-Credit-Loss (ECL) overlay — structured as evidence for the Bank of Ghana Climate-Related Financial Risk Directive and IFRS S2 / TCFD.
○ Screening data: seed location model — instant, zero-load default. Run a live screen (SafeGround + FloodGuard) for engine-backed flood, riparian, coastal and land layers.
Vulnerability is a weighted composite of flood, coastal, heat, riparian, land and drought hazards (weights in §Methodology). Bands: Low <25, Moderate 25–50, High 50–75, Critical ≥75 (of 100).

Disparate-impact view: localities where High+ risk and repricing concentrate. A flagged locality is where risk-based outcomes could disproportionately affect a community — every high-risk asset routes to adaptation structuring (never a location denial), and price-based exclusion is the bank's market-conduct responsibility.
1 locality flagged where the High+ rate is ≥ 50% (≥ 1.5× the book's 12% average).

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.
Two channels, kept separate. (1) Physical damage — an Average Annual Loss (AAL) per hazard from a depth-damage × frequency proxy: GHS 245k/yr of expected (mostly uninsured) damage. (2) Market repricing — a forward collateral devaluation that raises stressed LTV and loss-given-default, driving GHS 6.19M of potential collateral shortfall and an GHS 72k/yr indicative climate ECL uplift. A single severe event in Greater Accra could cause GHS 487k 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.

Top 12 by exposure × vulnerability. Full per-asset detail is in the CSV export.
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.

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.
| # | Area | What is required | Owner | Severity |
|---|---|---|---|---|
| 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 |
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). Each hazard is scored 0–1 from a Ghana location model (SEED) and, in live 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.
PortfolioCheck screens the institution's anonymised mortgage / property book on Ghana-resolution engines and returns a board- and BoG-Directive-ready report like this — with the collateral, LTV and climate-ECL overlay, scenario horizons and a green-loan origination shortlist. Your loan data can be screened on-premise so it never leaves the bank.
