Hybrid LLM + Higher-Order Quantum Approximate Optimization for CSA Collateral Management
This research introduces a novel, certifiable hybrid pipeline for finance-native collateral optimization under ISDA Credit Support Annexes (CSAs). It integrates an evidence-gated Large Language Model (LLM) for term extraction, a quantum-inspired explorer using micro Higher-Order Quantum Approximate Optimization Algorithm (HO-QAOA) for discrete optimization, and CP-SAT for formal certification. By encoding complex constraints like rounding and caps as higher-order terms, the method coordinates multi-asset moves effectively, outperforming strong classical baselines (BL-3) by 9.1% to 10.7% across various scenarios. The approach emphasizes governance-grade artifacts for auditable and reproducible results, delivering superior cost-movement-tail frontiers.

Collateral management under ISDA Credit Support Annexes (CSAs) involves complex, legally binding rules, leading to rugged search spaces due to integer lots, haircuts, rounding, minimum transfer amounts, and concentration limits. Suboptimal allocations result in trapped liquidity and fragmented inventories, incurring material costs. This paper addresses these challenges by proposing an automated, enterprise-grade solution.
The hybrid pipeline aims to optimize collateral allocation by integrating document understanding, advanced discrete optimization, and formal certification, ensuring both performance and auditability in a finance-native context.

The core of the methodology lies in its hybrid nature. An LLM acts as the first stage, extracting crucial CSA terms into a normalized, span-cited JSON format. This data then feeds into a quantum-inspired explorer that leverages micro Higher-Order QAOA (HO-QAOA) interleaved with simulated annealing. HO-QAOA is specifically designed to handle the higher-order domain couplings (e.g., RA/MTA interactions and concentration caps) that defeat simpler local search algorithms. Finally, CP-SAT acts as the arbiter, certifying feasibility and identifying any gaps, ensuring robust and verifiable solutions.
The hybrid pipeline was rigorously benchmarked against strong classical baselines (BL-1, BL-2, BL-3) across realistic government bond datasets and multi-CSA inputs under various governance settings. Our approach consistently improves the objective function, achieving gains from 9.1% to 10.7% over BL-3. This significant improvement is attributed to the HO-QAOA's ability to coordinate multi-asset moves that transcend local optima, particularly in scenarios with tight buffers and cash caps where overshoot control is critical.
The results show superior cost-movement-tail frontiers, demonstrating the hybrid's capability to deliver better trade-offs between operational costs, tail risk (CVaR), and funding-priced overshoot. This performance is achieved while maintaining certifiability and producing governance-grade artifacts for auditability.
| Feature/Model | BL-3 (Baseline) | Hybrid Pipeline |
|---|---|---|
| Objective Improvement | Reference (1.00x) | 9.1% Better (0.91x) |
| Movement (lots) | 24 | 22 |
| CVaR ($, normalized) | 520,000 | 515,000 |
| Overshoot ($) | 182,000 | 155,000 |
| Key Advantage | Strong local polish, prone to plateaus |

A key focus of this pipeline is auditability and reproducibility. We generate a suite of governance-grade artifacts for every run. These include span citations from the LLM extraction, a valuation matrix audit, detailed weight-provenance JSON, QUBO manifests (documenting subset size, order, and depth), and full CP-SAT traces (status, bounds, slacks). These artifacts ensure transparency and allow for complete verification of the solution and its components, critical for operational sign-off in regulated financial environments.
