How To Adjust To A Large Fall In Commodity Prices

Resource-rich countries have to manage highly volatile commodity revenues. In periods of revenue booms there is a tendency for large spending scale-ups. When facing large and persistent reductions in commodity prices, some of these countries will need to adjust their budgets to the new reality. In many cases, overall surpluses turn into large fiscal deficits and borrowing costs tend to rise with the fall in commodity prices. This note discusses how to undertake large fiscal adjustments, which often tend to be protracted and with long-lasting impacts on growth. Consequently, the note also highlights how to better prepare for future booms and busts in commodity prices.

Commodity-exporting countries have significantly benefited from the commodity price boom of recent years. At the current juncture, however, uncertain global economic prospects have raised questions about their vulnerability to a sharp fall in commodity prices and the policies that can shield it from such a shock. To address these questions, this paper takes a long term (4 decade) view at emerging markets' commodity dependence, the history of commodity price busts and the role of policies in mitigating or amplifying their economic impact. The paper highlights the stark difference in trends between Latin America - one of the most vulnerable regions given its high, and rising, commodity dependence - and emerging Asia - which has evolved from being a net exporter to a net importer of commodities in the last 40 years. We find evidence, however, that while commodity dependence is an important ingredient, a country's ultimate degree of vulnerability to commodity price shocks is to a great extent determined by the flexibility and quality of its policy framework. Policies in the run-up of sharp terms-of-trade drops - especially when those are preceded by booms - play a particularly important role. Limited exchange rate flexibility, a weak external position, and loose fiscal policy tend to amplify the negative effects of these shocks on domestic output. Financial dollarization also appears to act as a shock "amplifier."

Commodity prices may be a leading indicator of inflation, because of the relative importance of flexible auction markets for the determination of these prices. Empirical tests using data for the large industrial countries as a group suggest that changes in commodity prices tend to lead those in consumer prices, and that the inclusion of commodity prices significantly improves the fit of regressions of a multi-country consumer price index. However, there does not appear to be a reliable long-run relationship between the level of commodity prices and the level of consumer prices.

This paper presents a comparative analysis of the macroeconomic adjustment in Chile, Colombia, and Peru to commodity terms-of-trade shocks. The study is done in two steps: (i) an analysis of the impulse responses of key macroeconomic variables to terms-of-trade shocks and (ii) an event study of the adjustment to the recent decline in commodity prices. The experiences of these countries highlight the importance of flexible exchange rates to help with the adjustment to lower commodity prices, and staying vigilant in addressing depreciation pressures on inflation through tightening monetary policies. On the fiscal front, evidence shows that greater fiscal space, like in Chile and Peru, gives more room for accommodating terms-of-trade shocks.

This paper discusses developments and prospects for energy, metals, and food markets since the early 2000s, the start of what is termed a commodities supercycle—the rise of commodity prices over a decade or more as a result of a rapid urbanization and an expansion of infrastructure. Macroeconomists often assume that technological innovation is exogenous (driven largely by external factors or forces), but this volume documents how innovation in energy markets is directly affected by prices. When oil, natural gas, or fossil fuels become scarce, prices increase. This stimulates innovation and the adoption of new technologies and techniques for recovery and use of these resources. Conversely, when these commodities are abundant, prices fall, slowing the pace of innovation and the adoption of new techniques. At the heart of international trade in commodities are cross-country differenc¬es in resource endowments. Natural resources are materials or substances that occur in nature and can be used for economic gain, and so these include not only reserves of hydrocarbons, minerals, fisheries, and forests, but also temperate weather, fertile land, and access to water, which are important to agriculture.

A two-country theoretical model is presented, showing the effects of monetary, fiscal, and supply-side disturbances on prices of primary commodities and manufactured goods, and on exchange rates. If monetary shocks dominate, then commodity prices should lead general price movements, and the level of commodity prices should be correlated with the general inflation rate. Country-specific commodity price indexes are developed for the major industrial countries. Several empirical tests broadly support the conclusions of the model. Commodity price levels tend to be cointegrated with consumer-price inflation rates. Commodity price movements contribute weakly to predictions of inflation rates but more strongly to predictions of turning points in inflation.

Fluctuations of commodity prices, most notably of oil, capture considerable attention and have been tied to important economic effects. This book advances our understanding of the consequences of these fluctuations, providing both general analysis and a particular focus on the countries of the Pacific Rim.

The April 2012 issue of the World Economic Outlook assesses the prospects for the global economy, which has gradually strengthened after a major setback during 2011. The threat of a sharp global slowdown eased with improved activity in the United States and better policies in the euro area. Weak recovery will likely resume in the major advanced economies, and activity will remain relatively solid in most emerging and developing economies. However, recent improvements are very fragile. Policymakers must calibrate policies to support growth in the near term and must implement fundamental changes to achieve healthy growth in the medium term. Chapter 3 examines how policies directed at real estate markets can accelerate the improvement of household balance sheets and thus support otherwise anemic consumption. Chapter 4 examines how swings in commodity prices affect commodity-exporting economies, many of which have experienced a decade of good growth. With commodity prices unlikely to continue growing at the recent elevated pace, however, these economies may have to adapt their fiscal and other policies to lower potential output growth in the future.
