Finding implicit subsidies in financial markets

Implicit subsidies in financial markets can be defined as expected returns over and above the risk free rate and conventional risk premia. While conventional risk premia arise from portfolio optimization of rational risk-averse financial investors, implicit subsidies arise from special interests of market participants, including political, strategic and personal motives. Examples are exchange rate targets of governments, price targets of commodity producers, investor relations of institutions, and the preference for stable and contained portfolio volatility of many households. Implicit subsidies are more like fees for services than compensation for standard financial risk. Detecting and receiving such subsidies creates risk-adjusted value. Implicit subsidies are paid in all major markets. Receiving them often comes with risks of crowded positioning and recurrent setbacks.

Commodity pricing

A new paper combines two key aspects of commodity pricing: [1] a rational pricing model based on the present value of future convenience yields of physical commodity holdings, and [2] the activity of financial investors in form of rational short-term trading and contrarian trading. Since convenience yields are related to the scarcity of a commodity and the value of inventories for production and consumption they provide the fundamental anchor of prices. The trading aspect reflects the growing “financialization” of commodity markets. The influence of both fundamentals and trading is backed by empirical evidence. One implication is that adjusted spreads between spot and futures prices, which partly indicate unsustainably high or low convenience yields, are valid trading signals.

The predictability of relative asset returns

Empirical research suggests that it is easier to predict relative returns within an asset class than to predict absolute returns. Also, out-of-sample value generation with standard factors has been more robust for relative positions than for outright directional positions. This has been shown for bond, equity and currency markets. Importantly, directional and relative predictability have been complementary sources of investment returns, suggesting that using both will produce best performance.

How bank regulatory reform has changed macro trading

The great regulatory reform in global banking has altered the backdrop for macro trading. First, greater complexity and policymaker discretion means that investment managers must pay more attention to regulatory policies, not unlike the way they follow monetary policies. Second, changes in capital standards interfere with the effects of monetary conditions and probably held back their full impact on credit conditions in past years. Third, elevated capital ratios and loss-absorption capacity will plausibly contain classical banking crises in the future and, by themselves, reduce the depth of recessions. Fourth, regulatory tightening seems to have reduced market liquidity and may increase the depth of market price downturns.

The latent factors behind commodity price indices

A 35-year empirical study suggests that about one third of the monthly changes in a broad commodity price index can be attributed to a single global factor that is related to the business cycle. In fact, for a non-fuel commodity basket almost 70% of price changes can be explained by this factor. By contrast, oil and energy price indices have been driven mainly by a fuels-specific factor that is conventionally associated with supply shocks. Short-term price changes of individual commodities depend more on contract-specific events, but also display a significant influence of global and sectoral factors. The latent global factor seems to help forecasting commodity index prices at shorter horizons.

What traders can learn from market price volatility

Equity and bond market volatility can be decomposed into persistent and transitory components by means of statistical methods. The distinction is relevant for macro trading because plausibility and empirical research suggest that the persistent component is associated with macroeconomic fundamentals. This means that persistent volatility is an important signal itself and that its sustainability depends on macroeconomic trends and events. Meanwhile, the transitory component, if correctly identified, is more closely associated with market sentiment and can indicate mean-reverting price dynamics.

Why financial markets misprice fundamental value

Experimental research has produced robust evidence for mispricing of assets relative to their fundamental values even with active trading and sufficient information. Academic studies support a wide range of causes for such mispricing, including asset supply, peer performance pressure, overconfidence in private information, speculative overpricing, risk aversion, confusion about macroeconomic signals and – more generally – inexperience and cognitive limitations of market participants.

FX strategies based on quanto contract information

Quantos are derivatives that settle in currencies different from the denomination of the underlying contract. Therefore, quanto index contracts for the S&P 500 provide information on the premia that investors are willing to pay for a currency’s risk and hedge value with respect to U.S. stocks. Currencies that command high risk premia and provide little hedge value should have superior future returns. These premia can be directly inferred from quanto forward prices, without estimation. Empirical evidence supports the case for quanto contracts as a valid signal generator of FX strategies.

Inflation: risk without premium

Historically, securities that lose value as inflation increases have paid a sizable risk premium. However, there is evidence that inflation risk premia have vanished or become negative in recent years. Macroeconomic theory suggests that this is related to monetary policy constraints at the zero lower bound: demand shocks are harder to contain and cause positive correlation between inflation and growth. Assets whose returns go down with higher inflation become valuable proxy-hedges. As a consequence, inflation breakevens underestimate inflation. Bond yields would rise disproportionately once policy rates move away from the zero lower bound.

The risk-adjusted covered interest parity

The conventional covered interest rate parity has failed in modern FX markets. A new HKIMR paper suggests that this is not a failure of markets or principles, but a failure to adjust the parity correctly for relative counterparty and liquidity risk across currency areas. Specifically, FX swap rates deviate from relative money market rates due to counterparty risk and from relative risk free (OIS) rates due to liquidity risk. Correct adjustment helps to detect true FX market dislocations.
