The Versatile Cost of Carry Model

The cost of carry model is a versatile framework for pricing forward and futures contracts across various asset classes. Despite its wide usage, it appears in numerous forms, causing confusion among investors and professionals alike. This post aims to demystify the cost of carry model and discuss its implications for different assets.

Understanding the Cost of Carry Model

At its core, the cost of carry model is a generalized formulation that accounts for the costs associated with carrying or maintaining a position in an asset until its expiration. The model accommodates four primary asset types: stocks, currencies, commodities, and fixed-income instruments. Although different markets have unique conventions, the cost of carry model remains consistent.

Time Value of Money and Interest Rates

A fundamental concept in pricing forward/futures contracts is the time value of money, which reflects the relationship between a known future value and its present worth. The time value of money is influenced by supply and demand dynamics in short-term risk-free interest rate markets. Interest rates, on the other hand, are mathematical relationships that map present values to future values or vice versa.

Common Interest Rate Specifications

There are several interest rate specifications used in financial markets. This post discusses four common ones: discrete interest with annual compounding, LIBOR (London Interbank Offer Rate) interest, discount interest, and continuous compounding interest. Each specification has distinct features that affect the pricing of forward/futures contracts.

Portfolio Implications for Specific Assets

The cost of carry model has implications for various financial assets, such as C (currency), TIP (Treasury Inflation-Protected Securities), EEM (iShares MSCI Emerging Markets ETF), QUAL (iShares MSCI USA Quality Factor ETF), and MS (Morgan Stanley). By understanding the model's implications, investors can make more informed decisions about their portfolios.
