CFO must decide whether to readjust the real estate portfolio spread with rates at 15% and fintechs compressing margins
Market Context
The Central Bank raised rates from 10.5% to 15% between September 2024 and June 2025. Despite this, bank credit grew 11.5% and corporate bond issuance rose 30%. Fintechs now account for 25% of the card market. The bank faces the decision: increase the spread to protect NIM—risking volume loss to fintechs—or maintain it and accept margin compression.

MAT-4 impact. 4 alternatives: aggressive repricing, gradual repricing, maintain with funding hedge, securitize a portion. Stress test in 3 interest rate scenarios. Mandatory CDO + CFO approval.
Monthly monitoring: NIM, origination volume, default by tier, churn to fintechs. Alert in month 3—default in the youth tier rose 2pp above baseline.
CFO confirms: partial result. NIM protected (+0.4pp). Origination volume dropped 8%—within acceptable limits. Youth default opened a new cycle focused on that segment.
Without governance (Standard)
- × Repricing approved in committee without elasticity analysis by segment
- × Default noticed 6 months later—already provisioned
- × Nobody knows if churn was due to price or market conditions
- × Next decision: cut price to recover volume—without knowing if it works
- × Auditor requests traceability. It doesn't exist.
With Arcogi governance
- ✓ Stress test across 3 rate scenarios before deciding
- ✓ Projected impact by segment—not "entire portfolio"
- ✓ Youth default detected in month 3—before becoming bad debt
- ✓ New cycle opened for the problematic segment—inherited context
- ✓ Complete trail for Basel III and internal audit
Financial — Repricing in a High-Interest Rate Scenario
Without Arcogi
The bank already has sophisticated data, ALM models, and high-level analytics. The analytical team simulates scenarios, projects the impact on NIM, and delivers recommendations to the committee. The decision is approved, but often without a formal trail that connects premises, alternatives, segmentation, responsibilities, and subsequent monitoring.
The problem is not a lack of intelligence. It is a lack of governance over the decision made from it.
Months later, default rates may rise in a specific segment, risk may issue an alert, and provisions may increase — without the organization being able to link this effect, with clarity and traceability, to the original repricing decision.
When auditing, risk, or the regulator demands a reconstruction of the decision, what often exists is committee material. Not a structured decision dossier.
With Arcogi
Arcogi transforms modeling into governed decision-making.
Alternatives cease to exist merely as scenarios in a deck and begin to be formally compared by segment, macroeconomic sensitivity, impact on risk, and regulatory adherence. The decision is approved by the applicable fiduciary chain, with explicit criteria, registered alternatives, and defined responsibilities.
If the journey is complete, tracking continues after execution: defaults, portfolio drift, and signs of deterioration are continuously monitored, with the ability to open a new cycle for the affected segment before the problem only appears in the consolidated report. Arcogi natively anticipates continuous monitoring, drift tracking, and automatic cycle reentry; the spec even uses PSI as a standard for telemetry.
When auditing or regulations ask for an explanation, the answer does not depend on a PowerPoint. It depends on a structured trail: who decided, among which alternatives, with what premises, with what gates, and with what observed result. The framework architecture establishes an immutable append-only repository containing the Decision Pack, monitoring signals, deviation alerts, and confirmed outcomes.
Why this matters to the C-level
Because banks already have sophisticated data, models, and analytics.
What is often still missing is the layer that governs how this intelligence becomes a decision, how the execution is tracked, and how the outcome is linked back to the original choice.
Arcogi does not replace ALM, risk, or analytics. It is the layer that connects premise, decision, execution, monitoring, and executive defensibility — especially when the decision affects margin, defaults, provisions, and regulatory capital. This is directly aligned with the required rigor for pricing and credit decisions regarding capital impact, functioning as the recommended operational mode for enterprise banking.
Essential
Full cycle with stress test + trail for Basel. CFO confirms result in 12 months. Company has an auditable dossier but lacks an early default alert.
Complete
Everything in Essential + monthly NIM and default monitoring. Youth deviation detected in month 3. Focused adjustment without reverting the entire strategy. The alert prevented 2pp from becoming millions in provisioning.
"The question was never whether we should readjust. It was: how much, for whom, when—and how to know quickly if it worked. Without that, it's just intuition with formal approval."
