The Cross-Section of Currency Risk Premia and US Consumption Growth Risk

Aggregate consumption growth risk explains why low interest rate currencies do not appreciate as much as the interest rate differential and why high interest rate currencies do not depreciate as much as the interest rate differential. We sort foreign T-bills into portfolios based on the nominal interest rate differential with the US, and we test the Euler equation of a US investor who invests in these currency portfolios. US investors earn negative excess returns on low interest rate currency portfolios and positive excess returns on high interest rates currency portfolios. We find that low interest rate currencies provide US investors with a hedge against US aggregate consumption growth risk, because these currencies appreciate on average when US consumption growth is low, while high interest rate currencies depreciate when US consumption growth is low. As a result, the risk premia predicted by the Consumption-CAPM match the average excess returns on these currency portfolios.

Information Shocks, Jumps, and Price Discovery -- Evidence from the U.S. Treasury Market

We examine large price changes, known as jumps, in the U.S. Treasury market. Using recently developed statistical tools, we identify price jumps in the 2-, 3-, 5-, 10-year notes and 30-year bond during the period of 2005-2006. Our results show that jumps mostly occur during prescheduled macroeconomic announcements or events. Nevertheless, market surprise based on preannouncement surveys is an imperfect predictor of bond price jumps. We find that a macroeconomic news announcement is often preceeded by an increase in market volatility and a withdrawal of liquidity, and that liquidity shocks play an important role for price jumps in U.S. Treasury market. More importantly, we present evidence that jumps serve as a dramatic form of price discovery in the sense that they help to quickly incorporate market information into bond prices.Financial markets

Business cycle variation in the risk-return trade-off

In the United States and other Organisation for Economic Co-operation and Development (OECD) countries, the expected returns on stocks, adjusted for volatility, are much higher in recessions than in expansions. We consider feasible trading strategies that buy or sell shortly after business cycle turning points that are identifiable in real time and involve holding periods of up to 1 year. The observed business cycle changes in expected returns are not spuriously driven by changes in expected near-term dividend growth. Our findings imply that value-maximizing managers face much higher risk-adjusted costs of capital in their investment decisions during recessions than expansions

Common Risk Factors in Currency Markets

http://rfs.oxfordjournals.org/content/early/2011/08/26/rfs.hhr068.fullWe identify a “slope” factor in exchange rates. High interest rate currencies load more on this slope factor than low interest rate currencies. This factor accounts for most of the cross-sectional variation in average excess returns between high and low interest rate currencies. A standard, no-arbitrage model of interest rates with two factors—a country-specific factor and a global factor—can replicate these findings, provided there is sufficient heterogeneity in exposure to global or common innovations. We show that our slope factor identifies these common shocks, and we provide empirical evidence that it is related to changes in global equity market volatility. By investing in high interest rate currencies and borrowing in low interest rate currencies, U.S. investors load up on global risk

Countercyclical Currency Risk Premia

We describe a novel currency investment strategy, the ‘dollar carry trade,’ which delivers large excess returns, uncorrelated with the returns on well-known carry trade strategies. Using a no-arbitrage model of exchange rates we show that these excess returns compensate U.S. investors for taking on aggregate risk by shorting the dollar in bad times, when the U.S. price of risk is high. The countercyclical variation in risk premia leads to strong return predictability: the average forward discount and U.S. industrial production growth rates forecast up to 25% of the dollar return variation at the one-year horizon. The estimated model implies that the variation in the exposure of U.S. investors to worldwide risk is the key driver of predictability

The International CAPM Redux

This paper presents new evidence that international investors are compensated for bearing currency risk. We present a new three-factor international capital asset pricing model, comprising a global equity factor denominated in local currencies, and two currency factors, dollar and carry. The model is able to explain a wide cross-section of equity returns from 46 developed and emerging countries from 1976 to the present, is also useful at explaining the risks of international mutual funds and hedge funds, and outperforms standard models proposed in the international asset pricing literature. We rationalize our findings with a simple model of endogenous exchange rate risk in complete markets, and identify the importance of correctly identifying the dynamics of quantities and market prices of risk

The Wealth-Consumption Ratio

To measure the wealth-consumption ratio, we estimate an exponentially affine model of the stochastic discount factor on bond yields and stock returns. We use that discount factor to compute the no-arbitrage price of a claim to aggregate US consumption. Our estimates indicate that total wealth is much safer than stock market wealth. The consumption risk premium is only 2.2 percent, substantially below the equity risk premium of 6.9 percent. As a result, our estimate of the wealth-consumption ratio is much higher than the price-dividend ratio on stocks throughout the post-war period. The high wealth-consumption ratio implies that the average US household has a lot of wealth, most of it human wealth. A variance decomposition of the wealth-consumption ratio shows less return predictability than for stocks, and some of the return predictability is for future interest rates not future excess returns. We conclude that the properties of the average US household’s portfolio are more similar to those of a long-maturity bond than those of stocks. The differences that we find between the risk-return characteristics of equity and total wealth suggest that equity is a special asset class
