This week’s meeting might provide an instant lift to the position. If the Fed cuts rates by more or less than the expected 50 bps, longdated swaption vol could rise in reaction, he added.

The reading below deals with some typical swaption strategies and the factors that originate them. First, read it carefully. Lehman Brothers and Credit Suisse First Boston are recommending clients to buy long-dated swaption vol ahead of the upcoming US Federal Open Markets Committee meeting. In the trade, the banks are recommending clients to buy long-dated swaption straddles, whose value increases if long-dated swaption vol rises.

Mortgage servicers and investors are keen to hedge refinancing risk with swaptions as interest rates fall, meaning that long-dated swaption vol should rise over the next several months, said an official at CSFB in New York. The traditional supply of swaption vol has been steadily decreasing over the last year, said (a trader) in New York. Agencies supply vol to dealers mainly via entering swaps with embedded options on the back of issuing callable notes. Over the past year, demand for callable notes has been decreasing due to high interest rate volatility, and lower demand from banks, one of the larger investors in callables. This decreased supply in vol for dealers would point to intermediate- and longer-dated swaption vol rising. Lehman is recommending a relative value trade in which investors sell short-dated swaption volatility, such as options, to enter 10-year swaps in one year, and buy long-dated swaption vol, such as the option to enter a 10-year swap in five years. The trade is constructed with at-the-money swaption straddles, weighted in such a way as to make this a play on the slope of the vol curve, which at current levels is more inverted compared to historical levels, noted (the trader).

a. Using cash flow diagrams, show the positions that agencies would take due to issuing callable bonds.

b. Why would the short-term vol decrease according to the market? Why would long-term vol increase?

c. What do you think an at-the-money swaption straddle is? Show the implied cash flow diagrams.

d. If the expectations concerning the volatilities are realized, how would the gains be cashed in?

e. What are the differences between the risks associated with the positions recommended by CSFB versus the ones recommended by Lehman?
