Exchange of cash flows between loans
A PTRS is a simple exchange of cash flows between two counterparties based on a notional amount. On one side, the buyer, taking a long position on commercial property, pays a fixed percentage interest rate or LIBOR plus a spread. In return, he or she receives a cashflow based on the annual total return of the property index. The seller, taking the equivalent short position, pays and receives cashflows that are exactly opposite.
The interest rate used by the market is typically the three-month LIBOR. The spread that is added reflects expectations of the future performance of the index, and what buyers and sellers are prepared to accept to take the position (see the property spread). In January 2008, many banks switched from the LIBOR-based to a fixed interest rate convention.
In the event that the annual total return is negative, i.e. if the capital value drops sufficiently to wipe out income returns, the total return buyer pays that negative return to the seller, in addition to the quarterly interest payments. The property index commonly used is an annual index, which is based on the actual performance of a large number of institutional portfolios and comprises an income or rental and a capital growth element.
In addition to swaps, contracts-for-difference (CFDs) are used as trading instruments. For deals on residential indices, such as the Halifax House Price Index, CFDs are already common. A CFD represents an index that is artificially set at 100 when the deal is done. Investors and hedgers then state the price at which they are willing to buy or sell the index at maturity. If two counterparties agree on a three-year deal at 112 and the index rises to 116, then the buyer receives 116 ? 112 = 4 times the contract size from the seller. The transactions are cash free until maturity, when profits and losses are settled. Many market participants find CFDs more intuitive than swaps.
Cash-settled payday loan contracts are available
After the launch of futures and options on regional home prices, CME announced a partnership with the commercial real estate index provider Global Real Analytics (GRA) on 6 September 2006. They listed future and option contracts based on the S&P/GRA Commercial Real Estate Indices (CREX) on 29 October 2007.
The S&P/GRA CREX indices capture underlying real estate dynamics by tracking transaction-based price changes in diverse property sectors and geographic regions. GRA has a 20-year history of capturing data and sees the new indices as a natural extension, suited for the use of publicly traded futures contracts.
Ten quarterly cash-settled contracts are available: a national composite index, five regional indices (Desert Mountain West, Mid-Atlantic South, Northeast, Midwest and Pacific West) and four national property type indices (retail, office, apartment and warehouse properties).
CME expects the users of the new property contracts to be different from those trading in housing derivatives. If someone hedges against house-price declines in an area, he or she develops or buys a house there. The commercial contracts, on the other hand, are designed for larger investors who hold commercial properties in their portfolios, such as pension funds and REITs.
To hedge real estate or home price declines, individuals can purchase put options based on a particular index. If prices fall, investors will naturally see the value of their real estate holdings decline, but they offset the losses with gains in the put options. The CME hopes that there will be enough speculators in the market to take the other side of the transactions.
