This paper investigates the effects of oil price shocks on stock market returns in emerging countries. It differs
from previous works in three main aspects: i) we distinguish three groups of countries, the largest net-oil
importing countries, the moderately oil-dependent countries, and the largest net-oil exporting countries;
ii) The potential influence of bullish and bearish market conditions on the causal relationship between oil
and stock returns is controlled for in our analysis; iii) The empirical investigation is based on an analysis of
long-term correlation and a conditional multifactor pricing model. Using data from twenty-five emerging
countries, our results suggest that oil price risk is significantly priced in emerging markets, and that the oil
impact is asymmetric with respect to market phases.

1. Introduction
Oil price movements are always closely watched by policymakers
and investor community as oil is considered as an important driver of
the economic and industrial activity. Since there is now evidence to
show that oil prices negatively affect economic growth through a
number of channels such as rising production cost, inflation, and
investor confidence (e.g., Hamilton, 2003; Kilian, 2008; Lardic and
Mignon, 2008), one would expect some degree of interdependence
between oil prices and stock market performance (Huang et al.,
1996). Further, for portfolio managers and in particular global inves-
tors seeking for international diversification benefits by adding assets
of emerging markets into their portfolios, new insights about the
impact of oil on the equity's risk-return profile in these markets are
of paramount important as they can properly manage the risk inher-
ent to their portfolios.
Analyzing the effects of oil price volatility on the behavior of
emerging stock markets is a main research question given that most
of emerging economies have expanding energy demand to build
their infrastructure and to insure their rapid economic growth. Several
indications may approve this argument. First, in contrast to previous cri-
sis periods, economic growth in emerging countries outperformed
growth in developed economies during the recent international
financial crisis, sparked off by the U.S. subprime crisis. With reference
to official statistics by the International Monetary Fund, the GDP of
developed countries in 2009 declined -3.6% on average, while the
GDP in emerging countries grew by 1.7%. In addition, some further fore-
casts indicate that emerging economies will account for about 50% of
the global GDP by 2050 and be a predominant driving force for the
world economic growth (Cheng et al., 2007). It should be stressed that
over the period 1990–2005 China and India exhibited a higher rate of
growth than the major OECD countries. These two countries grew at av-
erage annual rates of 7.7% and 7.2% respectively, while OECD economies
only reached an average annual rate of 2.5% during the same period.
Along with this rapid economic growth within the emerging universe
and especially in India, China, Brazil and Russia (BRIC), global demand
for oil grew annually by an average of 1,153 million barrels per day
over the period 2001–2010.

In this paper, we attempt to examine the extent to which emerg-
ing market returns are associated with oil price fluctuations. As
discussed above, the fast economic growth of emerging economies
over the recent decades suggests that they consume an important
quantity of energy and may thus be heavily dependent oil production
and supply. Unfavorable changes in oil prices would reduce their eco-
nomic performance, leading to lower their diversification benefits be-
cause of less cash-flow generated by firms' activities. On the other
hand, the heterogeneity of emerging markets in terms of economic
structure, economic and market development levels as well as
