Research on the usefulness of the RYG in predicting economic conditions such as future economic growth and inflation (Armah & Swanson 2011; Davis & Fagan 1997) as well as stock market returns (Maio 2013) has been done in the United Kingdom (UK) as well as the United States (US). Nobili (2006) explains that if the prices of assets in the market are set by rational investors then it must be that yield spreads, such as the RYG, contain information about investors’ expectations for the future.
