Inefficient benchmarking and trading opportunities

Academic research explains how benchmarking induces investment managers to buy overvalued highly volatile assets. This makes markets inefficient and may even lead to a negative relation between risk and return. It also offers opportunities for investment strategies. First, value investors can exploit the market’s proclivity to overvalue high-beta and high-volatility assets. Second, momentum traders can exploit the flows of funds in the benchmarked industry.

How to measure economic uncertainty

Measures of economic uncertainty help investors to track popular fear or complacency for the purpose of trading strategies. Academic papers propose various methods: keyword frequencies in news, equity market volatility, earnings forecast dispersion and economic forecast disagreements. Composite measures suggest that uncertainty typically rises abruptly but declines just gradually.

U.S. natural interest rate stuck at 0%: evidence and consequences

Federal Reserve research supports the view that the natural rate of interest in the U.S. has not recovered from its plunge to an unprecedented historical low of close to zero after the great recession. This bodes for protracted problems with the zero lower bound emphasizing the ongoing importance of asset purchases and other non-conventional policy options for central bank credibility.

The limitations of ECB bond purchases

The European Central Bank’s public sector bond purchases are sizeable and their pace may increase further. However, issue and issuer limits constrain their time horizon. For monetary easing to remain credible and powerful the purchase of uncovered bank bonds and corporate bonds may have to be considered.

Rational informational herding

It can be rational for traders to buy with rising prices and sell with falling prices. In particular, this should be the case if traders possess private information suggesting that “something big” is coming and that prices may move significantly, even if direction is not certain (e.g. “make-or-break” situations). Experiments confirm such rational informational herding.

Why money markets remain vulnerable

New theoretical work shows that money markets remain fragile as long as there is a connection between asset prices, secured funding and unsecured funding. The degree of fragility depends on leverage in the financial system. Central banks can alleviate acute liquidity stress but cannot easily reduce financial system leverage. Hence fragility remains even with ultra-easy monetary conditions.

What we can learn from the “fiscal theory of inflation”

Fiscal policy is as important as monetary policy for inflation dynamics. Government debt has features similar to money and affects private wealth and prices. In particular, if monetary policy protects debt sustainability expansionary fiscal policy is inflationary and restrictive fiscal policy is dis-inflationary or deflationary. Moreover, high interest rates are inflationary and low interest rates are deflationary.

EM exchange rates and self-reinforcing trends

Emerging market exchange rates can be catalysts of self-reinforcing trends. Currency appreciation raises both global lenders’ risk limits and EM institutions’ debt servicing capacity. Currency depreciation spurs the reverse dynamics. Their escalatory potential constrains central banks’ tolerance for exchange rate flexibility.

China’s “double impact” on commodity prices

China consumes about one third of the world’s commodities. However, its influence on commodity prices goes beyond that. Chinese institutions are also major users of commodities as collateral. Empirical evidence shows a significant link between domestic lending and global commodity prices, particularly through so-called commodity financing deals.

Non-conventional monetary policy and global finance

Empirical evidence shows that non-conventional monetary policy in large advanced economies has shaped financial conditions in the rest of the world. In particular, non-conventional easing has boosted EM bank balance sheets and securities issuance. This goes some way in explaining why the emerging world has become so vulnerable to even just tapering of these policies.
