Case Study: Fannie Mae achieves 60% system footprint reduction and 66% faster time-to-market with SimCorp Dimension (SimCorp)

Ensuring liquidity with system modernization and consolidation

Fannie Mae, a leading provider of mortgage financing, faced aging, siloed technology that drove up maintenance costs, created stability and reconciliation issues, and slowed time to market. To modernize and consolidate its trading and operations platform, Fannie Mae partnered with SimCorp and deployed SimCorp Dimension to address complex multi-asset accounting and replace legacy systems.

SimCorp implemented SimCorp Dimension using an agile, iterative approach that integrated smoothly with Fannie Mae’s existing environment and third-party systems. The consolidation cut system footprint by 60%, reduced interfaces by 50%, slashed manual processes by 80%, shortened average release duration by 66%, and allowed 50% of staff to be redeployed to higher-value work—delivering faster time to market, lower operational risk, and improved agility.
