Context Graph and Decision Graph in Financial Services

Financial services institutions are automating decisions faster than they are governing them.

Credit approvals, fraud interventions, transaction blocks, pricing exceptions, and AML escalations are no longer episodic, human-only actions. They are continuous, contextual decisions executed at machine speed.

Yet most institutions still rely on:

• Post-hoc explanations

• Fragmented audit logs

• Model-centric controls

This gap is where regulatory risk now lives.  Context Graph and Decision Graph are not AI features. They are decision infrastructure, and Context OS provides the substrate that makes AI regulator-grade by construction.

“Regulators don’t examine models. They examine decisions.”

Why Regulators Care About Why, Not Just What

Across BCBS guidance, SR 11-7, and global Model Risk frameworks, supervisory expectations consistently require:

• Decisions to be understandable

• Assumptions to be traceable

• Controls to be enforced before harm

• Outcomes to remain reviewable over time

What regulators do not accept:

• Black-box reasoning

• Implicit judgment

• Reconstruction after the fact

Most AI failures in financial services are not accuracy failures. They are governance failures.

How does this help with BCBS and SR 11-7 compliance?

It enforces governance structurally, ensures traceability, validates authority, and preserves decision rationale over time.

Common Decision Failure Modes Regulators Identify

These are not edge cases. They are structural gaps exposed during examinations.

Systems of Record vs. Systems of Decision

Financial institutions have perfected systems of record. They lack systems of decision-making.

Regulators are not asking:

“What score did the model produce?”

They are asking:

“Why was this decision allowed, under this policy, at this time, by this authority?”

That is a decision-level question, not a model-level one.

What Is a Governed Context Graph?

A Context Graph captures the decision environment that regulators implicitly assume exists.

It accumulates:

• Customer relationships across products and accounts

• Behavioral signals and transaction patterns

• Policy constraints and regulatory boundaries

• Organizational authority and approval thresholds

• Historical decisions and outcomes

This directly aligns with BCBS expectations around:

• Risk aggregation

• Cross-line consistency

• Contextual risk assessment

Context Graph does not replace models. It provides the governed environment in which model outputs become decisions. Importantly, the structure is learned from decision traces, not designed upfront. It reflects how the institution actually operates, not how it was documented.

Why do regulators care more about decisions than models?
Because regulatory risk arises from how models are used — not from their accuracy alone.

What Is a Decision Graph?

If Context Graph represents the environment, Decision Graph represents the decision itself. A Decision Graph captures complete Decision Lineage for a single regulated decision:

This is exactly what regulators expect — but rarely receive.

Not a log.
Not a summary.
A causal, queryable reasoning structure defensible years later.

Mapping to SR 11-7 (Model Risk Management)

SR 11-7 governs models. Decision Graph governs how models are used in decisions — where most findings occur.

Mapping to BCBS Principles

Context Graph becomes the integration fabric BCBS assumes exists — but never prescribes technically.

Model Risk vs. Decision Risk

Decision risk is where examinations find gaps.

Example: AML Escalation Decision

Traditional Approach

• Transaction flagged

• Model score exceeds threshold

• Analyst escalates “based on experience.”

During examination:

• Why this case and not similar ones?

• Which policy version applied?

• Who had the authority to decide?

Answers are narrative — not structural.

With Context Graph + Decision Graph

The Decision Graph records:

• Transaction patterns + customer history

• Model outputs with confidence and version

• Policy thresholds are active at decision time

• Similar historical cases retrieved

• Authority verified explicitly

• Rationale recorded structurally

Five years later, the decision is retrievable, explainable, and defensible.

Deterministic Enforcement: Governance by Architecture

Regulators don’t want:

• More dashboards

• More reports

• More narratives

They want:

• Deterministic governance

• Explainable decisions

• Provable controls

Deterministic Enforcement means:

Policy violations aren’t detected. They’re structurally impossible.

If authority, policy, or context conditions aren’t satisfied, the execution path does not exist.

Progressive Autonomy (Regulator-Compatible)

Decision Graph enables graduated autonomy:

Trust Benchmarks gate progression:

• Decision accuracy

• Escalation quality

• Lineage completeness

• Policy compliance

• Authority verification

If benchmarks slip, authority contracts automatically.

From Model-Centric to Decision-Centric Governance

Models are components. Decisions are what regulators examine.

The Takeaway

Models predict.
Rules constrain.
Decision Graph governs.

Context Graph captures financial reality. Decision Graph captures regulated reasoning. Together, they form the decision substrate required for:

• BCBS alignment

• SR 11-7 compliance

• Defensible AI autonomy

• Regulator-grade governance

Without them:

• Autonomy stalls

• Examinations require reconstruction

• Decision consistency is unprovable

With them:

• Governance is structural

• Examinations become retrieval

• Trust compounds through evidence
