Metals price distortions and the warehouse system

In a short note Macquarie’s commodity research reviews price distortions and prospective changes related to the warehouse system of the London Metals Exchange (LME). Since 2008 LME warehouses have effectively withdrawn over 4 million tons of aluminium from the physical markets, producing a record premium for physical delivery versus exchange spot prices. Premiums have also climbed for other metals. A future increase in mandatory load-out rates could compress premiums but also adds to uncertainty about the resulting adjustment in exchange prices.

U.S. Fed “tapering”: The basics in the FOMC’s own words

Envisaged Fed tapering is simply predicated on five principles: (a) balance sheet expansion will slow and ultimately cease if unemployment declines on a sustained basis to around 7%, (b) the pace of asset purchases remains data dependent, hinging on sustained labor market improvement and financial conditions, (c) tapering is not meant to tighten monetary conditions, (d) tapering does not per se lead to subsequent unwinding of Treasury holdings and may never result in MBS sales, and (e) tapering does not per se bring forward Fed fund rate hikes, which are subject to higher thresholds.

What we can learn from Asia’s “tapering”

J.P. Morgan’s David Fernandez points out that central bank “tapering” (moderation of balance sheet expansion and related monetary accommodation, currently envisaged by the U.S. Federal reserve) has a precedent of sorts. Emerging Asia had ramped up central bank assets for a decade after the 1997-98 crisis, mainly though FX interventions to bolster financial stability and competitiveness. Asia has been unwinding part of that expansion, passively and in line with smaller external surpluses, since 2008. The initial balance sheet expansion did not undermine credibility and price stability. And the subsequent reduction may be interpreted as a positive normalization, reducing the risk of financial bubbles.

Efficient use of U.S. jobless claims reports

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.

Monetary financing does not preclude sovereign default

Most investors take for granted that a government with access to monetary financing cannot be driven to default. However, a new paper by Corsetti and Dedola challenges this belief. Monetary financing incurs costs and, hence, preference for default and self-fulfilling confidence crises are possible. Necessary conditions to rule out self-fulfilling crises include credible caps on government borrowing rates, the ability of the central bank to issue default-free, interest-bearing, and non-inflationary “reserves” (rather than cash), and full coverage of central bank losses by the state budget.

Self-fulfilling tightening and recessions in a low interest rate world

A new Bank of England paper points to a dangerous pitfall for monetary policy in a low rates environment. “Speed-limit rules” stipulate that central banks adjust policies in accordance with the change in the economy (e.g. growth, the unemployment rate, or inflation), not its level, in order to avoid policy errors and anchor expectations. At the zero bound these rules can lead to self-fulfilling recessions, as a downshift in (growth and inflation) expectations triggers less hope for policy easing than fears for subsequent tightening (when the initial downshift is being reversed). In my view this dovetails recurrent fears of convexity or jump risk in low-yield bond markets, and may help explaining why global central banks at the zero bound have so far struggled to produce sustained recoveries.

The structural rise in cross-asset correlation

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.

Overshooting of U.S. Treasury yields

The U.S. rates research team of Bank of America/Merrill Lynch reasons that fears of less accommodative monetary policy can trigger a rise in U.S. Treasury yields that goes beyond the rationally expected path in fed funds rates. Catalysts of such non-fundamental dynamics can be (i) increased mortgage convexity risk, (ii) spillovers and repercussions from other bond markets, and (iii) duration hedging in the wake of bond fund outflows. Thereby, large institutional flows in a market with few players to warehouse risk can lead to an overshooting of yields.

China’s augmented fiscal challenge

A very short note by the IMF in the run-up of China’s latest Article IV consultations suggests that the country’s fiscal position is much weaker than official statistics suggest. The augmented fiscal deficit of the country, including local government off-budget funding, is estimated to have climbed to around 10% of GDP.

On “institutional herding”

Herding denotes broad uniformity of buying and selling across investors. If the transactions of one institution encourage or reinforce those of another, escalatory dynamics, liquidity problems, and pricing inefficiencies ensue. A Federal Reserve paper (which I noticed belatedly) provides evidence of herding in the U.S. corporate credit market during the 2003-08 boom-bust experience, particularly during sell-offs. Bond herding seems to be stronger than equity herding. Subsequent to herding dynamics price reversals have been prevalent, consistent with the idea of temporary price distortions.
