“One problem was that we could issue only thirty-year securities. In the capital markets, there are a limited number of investors with thirty-year money. There are fewer investors looking for thirty year securities than for ten-year or two-year securities… ”

~Lewis Rainieri

What We Do

We solve a structural problem that impacts the mortgage markets.

  • DXM is an innovative solution to disaggregate and redistribute mortgage credit, prepayment and interest rate risks in a bespoke manner.
  • Banks can increase their risk-adjusted return on equity from residential mortgages.
  • Investors can create customized assets with maturities at any point along the yield curve.
  • DMX helps attract new pools of liquidity from shorter duration investors into an increasingly liquidity constrained mortgage market.

How We Do It

Using advanced technology, we enable the splitting of all risks (interest rate, prepayment and credit) and funding from any fixed rate residential mortgage.  This is achieved by enhancing standard interest rate swaps (“Mortgage Swaps”) employed in securitizations.

– Major DC Law Firm

Concluded that DXM solved a 40 year old problem to efficiently split interest rate, credit and funding risks from residential fixed rate mortgages. Specifically, DXM enables, for the first time, 30 year fixed rate MBS to be transformed into mortgage instruments with maturities at all points along the yield curve.

– Former Head of Capital Markets

Agreed that cash flows of DXM Mortgage Swaps provide a perfect offset to the cash flows of the underlying mortgage instrument.  Thus, transactions uniquely qualify for hedge accounting.
