A computer implemented method and associated hardware provides optimization of a delivery or settlement process for a group of portfolios. Data records, identified in a portfolio data structure, are indicative of obligations between participants. A graph data structure is generated and includes vertex data records representing the participants and edge data records representing the obligations between participants. The graph structure is analyzed for at least one circular path. A first edge washing out at least a portion of the circular path is identified. An update message is generated in response to the first edge.
