Why Structured Products Today

Fed Funds “higher for longer” regime -> Carry in a range bound market (unless Fed Fund going to 6% or higher) -> Structured product The range of Structured products are cheap today.

Valuations are further supported by the limited supply of our target assets.

We believe Structured products are in a position to outperform in both soft and hard landing scenarios Structured products are by their nature shorter duration – will benefit from today’s inverted yield curve normalizing.

Longer maturity of the yield curve might be further affected by QT even as Fed pause Hedging currently enhances carry (by paying fixed rate on long end, and receiving money market rates on short end), while preserve spread duration of underlying securities Currently, we continue to focus on sectors with high (rating) quality, shorter duration and high carry, e.g. Agency 5-year IO, Multi-family Credit Risk Transfer, selective high-quality home-equity/2nd lien (given high mortgage rate and suppressing refi activity), and floating rate assets.

We also see opportunities in the rate and volatility front, both for hedging and forward steepeners.
