Understanding global liquidity

A new IMF policy paper defines global liquidity as the ease of funding in global financial markets. The concept is useful for understanding the commonality in global financial conditions, with four large financial centers dominating the world’s institutional funding. In the 2000s banks have been the main conduit of financial shock propagation, but asset managers may play a greater role in the 2010s (see also posts herehere and here).

A theory of herding and instability in bond markets

A theoretical Bank of Japan paper suggests that instability and herding in bond markets arises from low overall confidence of investors, great importance of public information (such as central bank announcements), and high value of privileged information. This analysis goes some way in explaining drastic bond market moves in the age of quantitative easing, such as the 2013 JGB market sell-off.

The structural vulnerability of local EM assets

The rapid growth in local-currency bond markets in emerging countries has transferred foreign exchange risk from local borrowers to global institutional investors and mutual funds. Gross capital inflows have soared, magnifying the dependence of flows on mutual fund holdings, particularly on volatile open-ended fixed income funds. In the wake of these changes the “beta” of local emerging market assets has risen and the tendency towards herding has increased.

Financialization of commodity markets: the basics

An academic summary paper shows how the structure of commodity markets has changed, most notably through the growth of commodity index investors. This has raised the correlation of commodities with other asset classes. Moreover, this financialization may impair at times the two key functions of commodity markets: risk sharing and price discovery.

How real money funds could destabilize bond markets

A paper by Feroli, Kashyap, Schoneholtz and Shin illustrates how unlevered funds can become a source of asset price momentum due to peer pressure and redemptions. Regulatory reforms that impair bank intermediation could compound negative escalatory dynamics. This raises the risk of dislocations in fixed income markets if and when extraordinary monetary accommodation is being withdrawn.

Herding in financial markets

Herding is a deliberate decision to imitate the actions of others. In financial markets with private information herding can be efficient for an individual asset manager, but increases the risks that the market as a whole is inefficient and fragile, particularly in the case of “information cascades”. A paper of Michael McAleer and Kim Randalj provides empirical evidence of herding in a range of futures markets.

Trend following in U.S. equities

Trend following is a systematic investment style that takes directional positions in accordance with the difference between the current price and a moving average. For longer moving averages most trend following strategies would have outperformed simple buy-and-hold and value-based strategies in U.S. equities for many decades. Moreover, the simplest rules have been the best: there has been no benefit in high-frequency trading, stop losses, and conventional complications.

How fear of disaster affects financial markets

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.

Commodity exchange prices: The curious case of aluminum

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.
