In 2006, the buy-side was easier to see and to find than the sell-side. Investors were keen to take exposure to the underlying property index, while few investors with physical property exposure were willing to sell. In 2007, the situation has changed. Many investors such as large insurance companies are now concerned about their property investment and willing to hedge, while it is no longer clear who wants to take on the exposure.

For professional real estate investors, derivatives on the IPD All Property Index are a relatively crude tool since these investors often want to express a view on more finely differentiated subsectors, such as retail warehouses or offices in central London. Sector swaps started to bring the market closer to the needs of fund managers. Disaggregation could further play an important role in the property swap market, since the All Property side could feed off growth in the sector trades.

The formal launch of the Property Derivatives Interest Group (PDIG) on 16 September 2005 has set the crucial signal for the property market in the UK, which may serve as a role model for property derivatives trading elsewhere. However, the UK is somewhat fortunate because the available indices that are run by IPD are mature and widely accepted as accurate. That is not (yet) the case in most other countries.

In 2006, the market could build on the growth of the previous year and attracted further investment banks. Several banks started to quote option prices on IPD’s main index. Further, it was hoped that the arrival of sectoral transactions would deliver a further boost to the market. However, after a few trades on sector and even subsector indices in 2006, there were no more such deals in the first half of 2007. In essence, it remained a simple swap and forward market on the All Property Index with a few option trades, before trading volume soared in the wake of the US subprime mortgage crisis. The uncertainty introduced by the crisis attracted a number of new participants in the property derivatives market.

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.

Several derivative products based on a housing index have been proposed to hedge housing exposure in academic literature. To improve the possibilities to pool and share housing investment risks, Case, Shiller and Weiss (1993) propose a market in futures contracts tied to regional house price indices. Englund, Hwang and Quigley (2002) suggest that there are large potential gains from policies or instruments that would permit households to hedge their lump investments in housing. Case et al. attribute the failure of the London FOX contracts in 1991 to the public’s lack of appreciation and understanding of such markets. Whether such appreciation for housing markets now exists remains an open question.

The US market is still looking for a common benchmark. Multiple public exchanges or platforms try to promote housing derivatives for builders, developers, lenders and professional investors with large positions in real estate based on different index families. Although the platforms have many differences, they all operate in a similar way to an ordinary stock market.
