MDX Indices

Vista MDX Indices™

Vista MDX Indices™ are mortgage credit default benchmarks based on Reference Obligations in Credit Risk Transfer (CRT) securities used by Fannie Mae and Freddie Mac (the GSEs). By referencing a large cross-section of US household borrowers, MDX indices capture essential trends in the credit performance of US housing and consumers. With clear, rules-based definitions for determining credit events and straightforward calculations for assigning values, MDX is designed for broad use as a benchmark for financial products including swaps and derivatives. Vista will publish a new MDX Series every six months, enabling the market to develop credit views across a range of borrower vintages.
