Monetary policy stance in one indicator

New research proposes to condense policy rates and balance sheet actions into a single implied short-term interest rate. To this end the term premium component of the yield curve is estimated and its compression translated into an equivalent change in short-term interest rates. This implied short-term rate can be deeply negative and allows calculating long time series of the monetary policy stance including times before and after quantitative easing. It is only suitable for large currency areas, however. Indicators of smaller open economies should include the exchange rate as well, as part of an overall monetary conditions index.

The consequences of increased financial collateralization

There has been a strong upward trend in collateralization since the great financial crisis. Suitable collateral, such as government bonds, is essential for financial transactions, particularly repurchase agreements and derivative contracts. Increased collateralization poses new risks. Collateral prices and haircuts are pro-cyclical, which means that collateralized transactions flourish when assets values rise and slump when asset values decline. This creates links between leverage, asset prices, hedging costs and liquidity across many markets. Trends are mutually reinforcing and can escalate into fire sales and market paralysis. Central clearing cannot eliminate this escalation risk. The collateral policies of central banks have become more important.

Passive investment vehicles and price distortions

The share of passive investment vehicles in financial markets has soared over the past 20 years. In the U.S. equity market it has risen from 12% to 46%. There is reason and evidence suggesting that this will lead to more market price distortions. First, index effects on prices have gained importance relative to other price factors. Second, there has been a reduction of differentials across equity returns within indices. And third, the rise in passive investment vehicles has coincided with the expansion of momentum strategies in active funds, giving rise to vast flows that all explicitly neglect fundamental value.

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.

Fixed income relative value

Relative value can be defined as expected price convergence of contracts or portfolios with similar risk profiles. For fixed income this means similar exposure to duration, convexity and credit risk. The causes of relative value are limited arbitrage capital and aversion to the risk of persistent divergence. Relative value in the fixed income space has been pervasive and persistent. Relative value trades can be based on parametric estimation of yield curves or comparisons of individual contracts with portfolios that replicate their essential features. The latter appear to have been more profitable in the past.

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.

How to use financial conditions indices

There are two ways to use financial conditions indicators for macro trading. First, the tightening of aggregate financial conditions helps forecasting macroeconomic dynamics and policy responses. Second, financial vulnerability indicators, such as leverage and credit aggregates, help predicting the impact of an initial adverse shock to growth or financial markets on the subsequent macroeconomic and market dynamics. The latest IMF Global Financial Report has provided some clues as to how to combine these effects with existing economic-financial data.

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.

Critical transitions in financial markets

Critical transitions in financial markets are shifts in prices and operational structure to a new equilibrium after reaching a tipping point. “Complexity theory” helps analysing and predicting such transitions in large systems. Quantitative indicators of a market regime change can be a slowdown in corrections to small perturbations, increased autocorrelation of prices, increased variance and skewness of prices, and a “flickering” of markets between different states. A new research paper applies complexity theory to changes in euro area fixed income markets that arose from non-conventional policy. It finds that quantitative indicators heralded critical structural shifts in unsecured money markets and high-grade bond markets.

Hedging FX trades against unwanted risk

When FX forward positions express views on country-specific developments one can shape the trade to its rationale by hedging against significant unrelated global influences. Almost all major exchange rates are sensitive to directional global market moves and USD-based exchange rates are typically also exposed to EURUSD changes. A simple empirical analysis for 29 currencies for 1999-2017 suggests that the largest part of these influences has been predictable out-of-sample and hence “hedgeable”. Even volatility-adjusted relative positions across EM or FX carry currencies may sometimes be hedged against market directional influences.
