Several recent empirical papers have challenged the ‘spanning hypothesis’, which holds that the level, slope, and curvature of bond yield curves are sufficient to forecast returns and estimate bond risk premia This column argues that these studies suffer from a previously unrecognised standard error bias. Controlling for this bias, false positives are found to be between six and twelve times more likely, suggesting that the evidence against the spanning hypothesis is substantially less convincing than would appear from the studies.

Determining ‘currency value’ is a century-old topic on which there is little consensus among economists. This column proposes a novel way of adjusting real exchange rates for key country-specific fundamentals to obtain better gauges of currency valuation levels. Adjusting for productivity, export quality, foreign assets, and output gaps is shown to isolate information related to currency risk premia across countries. This can serve as a more precise input into investment and policy decisions.

Futures prices are a potentially valuable source of information about market expectations of asset prices. This column discusses a general approach to recovering this expectation when there is no agreement on the nature of the time-varying risk premium contained in futures prices. The authors illustrate this approach by tackling the long-standing problem of how to recover the market expectation of the price of crude oil.

Eurozone monetary policy transmission is broken. A key aspect of this is the failure of credit to get to small and medium enterprises, and consumers. This column uses the ‘I theory of money’ to diagnosis the problem and propose ‘prudently designed’ asset-backed securitisation as the cure. This would transform illiquid SME and consumer loans into a liquid asset class that would broaden the transmission mechanism while providing a lasting intermediation market for this segment in the Eurozone.

This column argues that asset purchases and forward guidance by central banks can be effective in reducing financial market participants’ tail-risk perceptions. US data suggest that, since their inception in 2008, the unconventional policies adopted by the Federal Reserve have significantly compressed perceptions of tail risk. Despite increases in risk premia during the recent ‘tapering’ episode, estimates of tail-risk perceptions still remain significantly below the levels observed when the measures were introduced. Still, the effects of exit on tail-risk perceptions remain uncertain, and will require careful monitoring.
