On the Linkage between the Energy Market and Stock Returns: Evidence from Romania

Abstract

his paper aims to establish whether the Romanian energy market has an influence on the good running of the associated capital market. In order to achieve this objective, we approached a series of econometric techniques that allowed us to study the cointegration between variables, the presence of short-term or long-term causality relationships, and the application of impulse-response functions to analyze how the BET index responds to the shocks applied. The empirical findings from the Johansen cointegration test, ARDL model, and VAR/VECM models confirmed both the presence of a long-term and short-term relationship between the energy market and capital market. From all energy market indicators, only hard coal presented a causal relationship with the BET index. We also noticed a unidirectional relationship from the WTI crude oil to the Romanian capital market. Our findings should be of interest to researchers, regulators, and market participants.

Oil Price and Stock Prices of EU Financial Companies: Evidence from Panel Data Modeling

“…They find that oil price changes have asymmetrical effects on renewable energy stock prices in the short-run but not in the long-run. Moving further, another study confirmed both the existence of a long-and short-term relationship between the Romanian energy market and the capital market using, among others, an ARDL model, on the basis of a mixture between stationary and non-stationary time series [39]. In addition to this, another research found that in the long-run oil price, similar to interest rates and real effective exchange rates, has a negative impact on Malaysia's stock returns, while industrial production has a positive impact [40].…”

Crude Oil Prices and the Egyptian Economy Evidence from the Stock Market

“…This study aims to investigate the multiple causes and theories connecting these crucial components of the global economy. Crude oil serves as a vital energy source for transportation, electricity generation, and diverse industrial applications, making it indispensable to the global economy (Armeanu et al, 2019;Cao et al, 2020). Factors such as supply and demand dynamics, geopolitical tensions, market speculation, and global economic conditions intricately influence crude oil prices.…”
