A Bundesbank paper proposes a new type of real exchange rate index. Rather than measuring the competitiveness of goods markets, this “real financial exchange rate” would measure the competitiveness of asset markets. There is some evidence that this indicator helps detecting overvaluation.
Fear of economic disasters, such as depressions, is more frequent than their actual occurrence. People tend to perceive a growing risk of disaster as they see economic conditions deteriorate. A new Federal Reserve paper illustrates that this pro-cyclicality of fears can trigger fluctuations in equity prices that go well beyond the actual changes in economic conditions, consistent with actual historical experience. Disaster fears also can make asset returns partly predictable.
Goldman Sachs Research takes another look at soaring warehouse queues and fears of price distortions in the aluminum market (see previous post here). A case can be made that inventories have risen as consequence of a supply surplus, rather than distortions. The price of physical metal, traded outside the exchange, appears to evolve in line with fundamentals. By contrast, the exchange price trades at a discount, because it only entitles to a warrant for cheapest delivery and not to physical metal at the required location. The variation of this discount constitutes basis risk for producers or consumers that use it for hedging, compromising the validity of the London Metals Exchange prices.
A research report by Jens Nordvig and his colleagues at Nomura shows that external (current account) surpluses have been a poor indicator of currency performance over the past 20 years. External deficits are often the consequence of growth outperformance, decreasing country risk premiums and capital inflows, and hence may be associated with currency strength rather than currency weakness.
Risk premia strategies can be defined as diversifiable investment styles with fundamental value and positive historic returns. Their main types are (i) absolute value and carry, (ii) momentum, and (iii) relative value. A Societe Generale research report argues that value generation of these styles may be more reliable than that of asset classes and more suitable for combination into diversified portfolios.
Two recent papers help understanding the information value of the implied volatility index for the S&P 500 stock index (VIX). An ECB paper de-composes VIX into measures of equity market uncertainty and risk aversion, e.g. the quantity and price of risk. Risk aversion in particular has been both a driver of monetary policy and an object of its effect. Meanwhile, a Fed paper emphasizes that the implied volatility of VIX (“vol of vol”) is a useful measure of tail risk prices and a predictor of tail risk hedges’ returns.
Risk parity portfolios allocate equal risk budgets to different assets or asset classes, most frequently equities and bonds. Over the past 30 years these strategies have outperformed traditional portfolios and become vastly popular. But a recent Commerzbank paper shows that outperformance does not hold for a very long (80 year) horizon, neither in terms of absolute returns, nor Sharpe ratios. In particular risk parity seems to be performing poorly in an environment of rising bond yields. And levered risk parity portfolios (“long-long trades”) are subject to considerable tail risk.
An empirical paper by Prokopczuk and Symeonidis investigates the drivers of commodity price volatility over the past 50 years. On the economic side inflation changes had been critical until price growth compressed over the past decade. Also economic recessions have been conducive to larger (industrial) commodity fluctuations. From the 2000s the importance of financial risk variables has gained weight, an apparent tribute to the “financialisation” of commodities trading.
U.S. weekly jobless claims are a key early indicator for the U.S. economy and global financial markets. A new Kansas City Fed paper suggests that to use these data efficiently one should first estimate a time varying benchmark for the “neutral level” of claims. Claims above (below) the benchmark would indicate deterioration (improvement) of the U.S. labor market.
Cross-asset correlation has remained high in recent years, despite the post-crisis decrease in volatility. Typically, correlation surges during financial crises, when macro risk factors dominate across markets. However, J.P. Morgan’s Marko Kolanovic and Bram Kaplan show that there has also been a secular increase in cross-asset correlation since 1990, due probably to globalization of markets, risk management and alpha generation techniques.
