Deep dives
Deepak Narula's Journey and Metacapital's Founding
Deepak Narula shares his professional journey, beginning with his engineering background in India and his move to New York City. He attended Columbia University, where he earned his Ph.D. in management science and finance, focusing on mortgage-backed securities. After a decade at Lehman Brothers where he managed mortgage strategy and trading desks, Narula left due to shifts in the firm's focus and the desire for a different trading style. In 2001, alongside his partner, he founded Metacapital Management, capitalizing on their expertise in mortgage trading and leveraging initial investments to build the firm.
Understanding Mortgage-Backed Securities (MBS)
Mortgage-backed securities (MBS) consist of pools of mortgages packaged together and sold to investors, where borrowers pay monthly mortgage dues that generate cash flow for bondholders. The structure ensures that a portion of the mortgage interest paid goes toward servicing fees and credit guarantees, with agencies like Fannie Mae and Freddie Mac protecting bondholders against defaults. The differences in prepayment options available to homeowners complicate MBS, making them callable bonds held by multiple borrowers. These prepayments can significantly impact the valuation and cash flows associated with MBS, thus requiring in-depth analysis and forecasting.
Current Market Dynamics and Lock-in Effects
The current U.S. mortgage market is characterized by homeowners benefiting from previously low interest rates, leading to an environment where most are unwilling to refinance at current higher rates. The average homeowner pays under 4% on their mortgage, creating a significant lock-in effect that discourages selling homes and leads to lowered market liquidity. As home prices rise and affordability diminishes, the reluctance to put homes up for sale exacerbates housing supply shortages. This dynamic contributes to sustained high home prices, as fewer sellers are willing to part with their low-rate mortgages.
Navigating Prepayment Models and Risk Management
Understanding borrower behavior and prepayment modeling is essential for evaluating MBS amidst fluctuating market conditions. The challenge lies in accurately predicting how homeowners react to changing interest rates, which can significantly alter prepayment rates. Models built on historical data may not fully capture future homeowner behavior, particularly in uncertain economic climates. Effectively managing risk associated with prepayments and market shifts enables Metacapital to capitalize on investment opportunities while maintaining stability amid volatility.
Implications of Potential Fannie and Freddie Privatization
The discussion surrounding the privatization of Fannie Mae and Freddie Mac raises questions about the future landscape of the mortgage market, especially in terms of spreads and stability. The government has indicated a desire to reduce its footprint in housing finance, which could lead to changes in the credit guarantees provided by these agencies. Anticipating the impacts of potential construction changes enables firms like Metacapital to adjust their strategies and manage associated risks effectively. The gradual evolution towards privatization will likely affect mortgage prepayment behavior and pricing dynamics, requiring active adjustment and risk management in portfolio strategies.
The mortgage market may be on the brink of major transformation amid freshly implemented tariffs, proposed deregulation and the potential privatization of Fannie Mae and Freddie Mac. In this episode of Credit Crunch, Bloomberg Intelligence’s Noel Hebert and Sam Geier are joined by Deepak Narula, founder and co-chief investment officer of Metacapital Management, to explore emerging opportunities in mortgage-backed securities (MBS). They discuss the negative convexity profile for the asset class, prepayment impacts, stagflation scenarios, utilizing machine learning models, Fannie Mae and Freddie Mac going private and more.
