Harley S. Bassman
The Convexity Maven
Harley Bassman created, marketed and traded a wide variety of derivative and structured products during his twenty six year career at Merrill Lynch. In 1985 he created the OPOSSMS mortgage options product that facilitated risk transmission between MBS originators and financial institutions. In 1988, he assumed responsibility for trading and marketing IO/PO and other levered prepayment securities. Soon after this, he started purchasing RTC auctioned MBS Servicing rights and repackaged them for the securities market as BIGS - Beneficial Interests in GNMA Servicing. Later, he started a GNMA servicing conduit becoming one of the Top 20 originators in 1992. As managing and hedging prepayment risk became a priority focus for the financial markets, Mr. Bassman created PRESERV, Merrill's trademarked Prepayment Cap product. Merrill was a leader in this product category writing protection that covered the risk on tens of billions of notional mortgage servicing rights. Later, Mr. Bassman managed Merrill's initial venture into off-balance sheet mortgage trading.
In 1994, Mr. Bassman assumed responsibility for OTC bond options.
Within a year, Merrill was the leader in this product sector. A wide variety of products were offered including vanilla and complex options on MBS spreads and the Treasury yield curve. From 1995 to 2000 he focused on creating hedge strategies for MBS servicers and portfolio optimization techniques for Total Return and Index investors.
Mr. Bassman became the manager of North American MBS and Structured Finance trading in 2001. During his tenure, he created SURF, (Specialty Underwriting and Residential Finance), a self contained Sub-Prime mortgage conduit. He supervised the issuance of Merrill’s first Sub-Prime securities. He also transitioned the structuring business to a new technology platform.
In 2006 he built the RateLab, a full spectrum US Rates Trading Desk Strategy Group. Here he worked with investors to advise and optimize their risk exposure. As a key member of the client trading business, he facilitated activity by providing liquidity to both the firm’s clients and market makers.
Re-invigorated after a (too) brief sabbatical, Mr. Bassman again transacts and opines about global markets under the moniker of The Convexity Maven where he identifies and integrates investment and hedging opportunities for sophisticated and qualified professionals.
Mr. Bassman has a B.A. in management science from the University of California, San Diego and an MBA in finance and marketing from the University of Chicago.
