The ongoing, synchronised disinflation across Europe raises the question of whether non-Eurozone EU countries are affected by the undershooting of the Eurozone inflation target, by other global factors, or by synchronised domestic, real sector developments. This column argues that falling world food and energy prices have been the main disinflationary driver. However, countries with more rigid exchange-rate regimes and/or higher shares of foreign value added in domestic demand have also been affected by disinflationary spillovers from the Eurozone.

The conventional ‘trilemma’ view is that countries that allow free capital flows can still pursue independent monetary policies as long as they allow flexible exchange rates. This column examines the pass-through of Federal Reserve interest rates to policy rates in Chile, Colombia, and Mexico. The author concludes that, to the extent that central banks take into account other central banks’ policies, there will be ‘policy contagion’ and that, even under flexible rates, monetary policy will not be fully independent.

Notwithstanding the progress made in the field of exchange rate economics, we still know very little of what drives major currencies. This column argues that the best that one can do is to assume that currencies move to gradually restore (relative) purchasing power parity. Contrary to widely held beliefs, this is in general a much better strategy than to just assume that the exchange rate behaves like a random walk.

The Swiss central bank last week abandoned its euro exchange rate ceiling. This column argues that the fallout from the decision demonstrates the inherent weaknesses of the regulator-approved standard risk models used in financial institutions. These models under-forecast risk before the announcement and over-forecast risk after the announcement, getting it wrong in all states of the world.

Since the Global Crisis, concerns have grown that advanced economies are suffering from secular stagnation. This column discusses the lessons that can be learnt from the economic transition of central and eastern Europe and the emerging-market crises of the late 1990s and early 2000s. Structural reform is particularly costly in the context of a debt overhang and an overvalued exchange rate. However, the crux is not debt restructuring per se, but whether economic governance changes credibly for the better following it.

Eurozone inflation has been persistently declining for almost a year, and constantly undershooting forecasts. Building on existing research, this column explores the conjecture that low inflation in the Eurozone results from an excess demand for safe assets. If true, this conjecture would have definite policy implications. Getting out of such a ‘safety trap’ would necessitate fiscal or non-conventional monetary policies tailored to temporarily take risk away from private balance sheets.

There has been a long-term downward trend in labour’s share of national income, depressing both demand and inflation, and thus prompting ever more expansionary monetary policies. This column argues that, while understandable in a short-term business cycle context, this has exacerbated longer-term trends, increasing inequality and financial distortions. Perhaps the most fundamental problem has been over-reliance on debt finance. The authors propose policies to raise the share of equity finance in housing markets; such reforms could be extended to other sectors of the economy.

Due to the adoption of inflation targeting and floating exchange rates, and the elimination of capital controls, exchange rate pass-through – the transmission of exchange rate movements to changes in the domestic price level – has become an increasingly important issue in developing and emerging market economies. This column discusses recent research on this topic, and highlights the frequent misspecifications that produce unreliable empirical estimates.

Last week, the ECB announced that it would begin purchasing securities backed by bank lending to households and firms. Whereas markets and the media have generally greeted this announcement with enthusiasm, this column identifies reasons for caution. Other central banks’ quantitative easing programmes have involved purchasing fixed amounts of securities according to a published schedule. In contrast, the ECB’s new policy is demand-driven, and will only be effective if it breaks the vicious circle of recession and negative credit growth.

Central banks’ exchange rate interventions are typically attributed to precautionary, prudential, or mercantilist motives. This column documents the prevalence of an alternative motive – that of stabilising the exchange rate – in emerging markets, where, despite heavy intervention, the Global Crisis saw important deviations of the real exchange rate from its equilibrium value. Exchange rate intervention is shown to be effective, but more so at containing appreciations than depreciations.

The IMF has recently revised its position on capital controls, acknowledging that they may help prevent financial crises. This column examines the effects of capital controls imposed during the Great Depression. Capital controls appear not to have been successfully used as tools for rescuing banking systems, stimulating domestic output, or for raising prices. Rather they appear to have been maintained as a means for restricting trade and repayment of foreign debts.

When the international comparison project published its latest estimates of purchasing power parity exchange rates in April there was some consternation. Poor countries became richer overnight, world GDP increased, and global income inequality was revised downwards. Alas, no one stopped being poor. This column digs into the numbers to see if we’ve been consistently underestimating the relative size of poorer economies and overestimating global poverty and inequality.

Trade imbalances in the Eurozone require relative price adjustments. This column argues that the traditional ‘elasticity’ approach is lacking when thinking about the adjustment magnitude. Exports adjust when exporting firms sell more (intensive margin) and new firms start exporting (extensive margin). The extensive-margin reaction depends upon the fatness of firm-level productivity distributions. Surplus-country distributions have fatter tails than deficit countries, suggesting that the price adjustment magnitude may be larger than traditional calculations suggest.

In 2013, policymakers began discussing when and how to ‘taper’ the Federal Reserve’s quantitative easing policy. This column presents evidence on the effect of Fed officials’ public statements on emerging-market financial conditions. Statements by Chairman Bernanke had a large effect on asset prices, whereas the market largely ignored statements by Fed Presidents. Emerging markets with stronger fundamentals experienced larger stock-market declines, larger increases in credit default swap spreads, and larger currency depreciations than countries with weaker fundamentals.

In a world of volatile capital flows, emerging markets are increasingly resorting to managing their exchange rates. But does this strategy increase their susceptibility to crisis? This column argues that while intermediate regimes as a class are the most susceptible to crises, ‘managed floats’ – a subclass within such regimes – behave much more like pure floats, with significantly lower risks and fewer crises. ‘Managed floating’, however, is a nebulous concept; a characterisation of more crisis prone regimes suggests that it is not the degree of exchange rate management alone, but the way the exchange rate is managed, that matters. Greater against-the-wind intervention by the central bank to prevent currency overvaluation reduces, while greater intervention to defend an overvalued currency raises, the crisis likelihood.

In recent years credit growth in Latin America has been very strong, and countries have become more reliant on foreign bond issuances. This column argues that these phenomena are linked, and may have led to vulnerabilities which domestic and international supervisors are not well-equipped to assess. There is no systematic information on firms’ currency mismatches and hedging activities, and none that includes those of subsidiaries that may be located in other jurisdictions, preventing an accurate analysis of the true risks.

Since the East Asian financial crisis of 1997, the emphasis on regional monetary cooperation has grown. This column discusses recent research into intra-regional exchange rate misalignments. In the aftermath of the Global Financial Crisis, investors in the US and Europe withdrew from emerging markets, causing a depreciation of emerging-market currencies against the US dollar. At the same time, the appreciation of the Japanese yen – fuelled in part by intra-regional capital flows – has increased the misalignment of intra-regional exchange rates.

Government interventions to control capital flows and reduce exchange-rate volatility have long been controversial. The Global Financial Crisis has made the debate more urgent. This column discusses recent research that evaluates such policies against the counterfactual of no intervention. Depreciations and reserve sales can boost GDP growth during crises, but may also substantially increase inflation. Large increases in interest rates and new capital controls are associated with reductions in GDP growth, with no significant effect on inflation. When faced with sudden shifts in capital flows, policymakers must ‘pick their poison’.

Fed tapering has started. A revival of last summer’s emerging economy turmoil is a real concern. This column discusses new research into who was hit and why by the June 2013 taper-talk shock. Those hit hardest had relatively large and liquid financial markets, and had allowed large rises in their currency values and their trade deficits. Good macro fundamentals did not provide much insulation, nor did capital controls. The best insulation came from macroprudential policies that limited exchange rate appreciation and trade deficit widening in response to foreign capital inflows.

Predicting exchange rates is still an inexact science. Economic models perform poorly, and a plethora of alternative methods have been attempted. This column guides the reader through the state of the art, reviewing various predictors, models, and data specifications. Despite a large and divergent literature chasing this holy grail, the toughest benchmark remains the random walk without drift.
