xHedge: OTC Derivatives Reconciliation

The Problem

OTC derivatives reconciliation requires counterparties to compare trade details, but sharing internal valuations and position data creates competitive intelligence risks.

T+1 settlement mandates require faster reconciliation of OTC derivatives. But counterparties resist sharing detailed position and valuation data needed for accurate matching.

Current reconciliation relies on trusted third parties or manual comparison. Both are slow and create data exposure. The OTC derivatives market exceeds $600 trillion in notional value.

The Old Way

The PRIVATE.ME Solution

xHedge enables counterparties to reconcile OTC derivatives on XorIDA shares via xCompute. Trade terms are verified to match without either party revealing internal valuations.

Each counterparty splits its trade record into XorIDA shares. Matching algorithms run on shares via xCompute, verifying that key terms (notional, rate, dates, parties) match without revealing the underlying valuations or hedge ratios.

Reconciliation results are HMAC-chained for regulatory reporting. Disputed trades are flagged for human review without exposing either party’s complete position.

The New Way

How It Works

xHedge combines xCompute matching on shares with xLink M2M authentication and HMAC-chained reconciliation reporting.

OTC Reconciliation Architecture

xHedge implements privacy-preserving portfolio reconciliation for OTC derivatives through cryptographic split-data matching. Each counterparty maintains complete control over proprietary valuation models and position data while meeting regulatory reconciliation requirements.

Split-Data Position Matching: Trade records are XorIDA-split into K-of-N shares before any comparison occurs. Material terms (notional amount, effective date, maturity date, payment frequency, reference rate, spread) are verified for equality across counterparties using xCompute operations on shares. Internal valuations, hedge ratios, and proprietary pricing models remain protected as individual shares reveal no information.

Reconciliation Frequency Automation: Portfolio size determines reconciliation cadence automatically. Portfolios exceeding 500 OTC derivative contracts trigger daily reconciliation. Portfolios between 51-499 derivatives reconcile weekly. Portfolios with 50 or fewer contracts reconcile quarterly. This tiered approach balances regulatory compliance with operational efficiency while maintaining zero data exposure regardless of frequency.

Trade Affirmation Protocol

Trade affirmation occurs through cryptographic matching without counterparty data exchange. Each institution prepares its trade record with material terms, splits via XorIDA, and distributes shares to designated affirmation nodes. xCompute equality checks run on shares to verify that both parties agree on transaction fundamentals.

Common Domain Model Integration: Trade data is normalized to CDM format before splitting, ensuring consistent field mapping across counterparties. Notional amount, currency, payment schedule, reference index, and legal entity identifiers are extracted and verified independently. Discrepancies generate HMAC-tagged mismatch reports identifying the specific field causing the break without revealing either party's full record.

Automated Confirmation Generation: Successful affirmation triggers immediate ISDA-compliant electronic confirmation. The confirmation document references HMAC chain identifiers proving cryptographic verification occurred. Legal enforceability is maintained through xLink digital signatures binding each party's identity to the affirmed terms. Settlement instructions flow automatically to post-trade systems once affirmation completes.

Regulatory Compliance

EMIR REFIT Requirements: European counterparties subject to EMIR reconciliation obligations achieve full compliance through xHedge. Portfolio reconciliation occurs at mandated frequencies (daily for large portfolios, weekly for medium, quarterly for small). HMAC-chained audit trails provide verification evidence for ESMA reporting. Valuation disputes are identified and time-stamped within the five-business-day resolution window required by EMIR Article 11.

Dodd-Frank Swap Data Reporting: U.S. swap dealers and major swap participants meet CFTC Part 45 recordkeeping requirements through cryptographic audit trails. Material terms reconciliation produces immutable verification records suitable for SDR reporting. Discrepancy resolution timestamps prove compliance with five-business-day dispute resolution rules. The system maintains reporting granularity (daily/weekly/quarterly based on portfolio size) without exposing proprietary valuation methodologies to regulators or counterparties.

Basel III Capital Adequacy: Banks using xHedge for OTC derivatives reconciliation generate the counterparty exposure verification evidence required for Basel III capital calculations. Credit valuation adjustment computations remain proprietary while reconciliation proofs demonstrate bilateral agreement on notional exposures and payment obligations. This satisfies Basel Committee standards for operational risk management in derivatives portfolios.

Reconciliation Break Management

When material term discrepancies are detected, xHedge generates a granular mismatch report identifying the specific field causing the break without revealing full trade details. For example, if notional amounts differ, the report indicates "Notional Mismatch Detected" with HMAC proof of the discrepancy, but neither party's actual notional value is disclosed.

Dispute Resolution Workflow: Breaks trigger a structured resolution process. Both parties receive mismatch notifications with field-level indicators. Human reviewers access their own institution's trade record to investigate the discrepancy. Corrections are made to internal systems, and reconciliation re-runs automatically. The HMAC audit chain timestamps every resolution attempt, creating regulatory evidence of good-faith dispute resolution within mandated timeframes.

Escalation and Exception Reporting: Breaks unresolved within three business days escalate to designated operations managers. Persistent discrepancies exceeding five business days generate regulatory exception reports. Throughout the escalation process, neither counterparty gains visibility into the other's proprietary data. Only the final resolution (agreement reached, trade canceled, or margin call triggered) is recorded in the shared audit trail.

Use Cases

Integration

import { DerivRecon } from '@private.me/xhedge';

const recon = await DerivRecon.create({
  partyA: bankDid,
  partyB: dealerDid,
  threshold: { k: 2, n: 3 }
});
const result = await recon.reconcile(tradeRef);

Security Properties

Verifiable Data Protection

Every operation in this ACI produces a verifiable audit trail via xProve. HMAC-chained integrity proofs let auditors confirm that data was split, stored, and reconstructed correctly — without accessing the data itself.
