Volatility vs. Price*

In recent years, the oil market has been characterised by rising, and at times, rapidly fluctuating price levels. In the last three months alone, Brent crude oil prices have fluctuated in a wide range from $125/bbl to $89/bbl. Higher volatility will certainly impact both consumers and producers. Oil exporting countries can be negatively affected by the impacts of high volatility in oil prices on fiscal revenues, investment and confidence in the economy. Higher volatility can have negative impacts on inflation and growth prospects in oil importing countries as well. As a response to observed higher prevailing volatility, for example, G20 leaders called for policy options to combat excessive price volatility in commodity markets in general, and in oil markets in particular. In order to reduce volatility in oil markets, the G20 experts group emphasised the importance of improving data transparency in both financial and physical markets as well as phasing out of inefficient fossil fuel subsidies. They also urged the use of country-specific monetary and fiscal responses to support inclusive growth in order to mitigate the impacts of excessive price volatility.

Do Exchange Rates Matter?*

Oil prices have experienced large fluctuations in recent years.  The spike in crude oil prices in mid-2008 to more than $140/bbl, followed by a steep correction in late 2008/early 2009 and subsequent sharp rebound over the last two years have jolted the world economy and pinched consumers at the fuel pump. US dollar weakness in recent years is frequently cited as one reason for high oil prices. It is very common to see the financial press suggesting that a weak dollar has pushed oil prices higher. However, this explanation is challenged by the empirical observations that (a) a change in oil price tends to lead to a change in the exchange rate as predicted by economic theory and (b) the oil price has risen regardless of what currency unit one uses to measure the price of oil.
