We investigate whether satellite observations of nitrogen dioxide (NO₂) - a short-lived pollutant primarily emitted by fossil fuel combustion - can improve the forecasting of oil demand. After retrieving, cleaning, and aggregating daily satellite data, we integrate NO₂ into a range of...

We quantify the contribution of Venezuela’s oil sector collapse to changes in global oil market responsiveness after 2007. We extend the multi-country structural model of Baumeister and Hamilton (2024) by modeling Venezuela explicitly and constructing a counterfactual production path that...

Background: This study revisits whether oil revenue windfalls translate into higher socio-economic welfare in oil-exporting economies and explains why oil price booms often fail to generate sustained gains in real GDP per capita. Methods: Using annual data for ten oil-exporting countries over...

This paper presents the first formal comparison of Value at risk (VaR) forecasting performance across various high-frequency volatility models and conventional benchmarks using daily data in the crude oil futures market. Our analysis reveals the following key findings:(1) High-frequency data...

This paper examines the dependence, systemic risk spillover, return and volatility spillover, and portfolio implications across various timescales between the Green Bond (GB) and U.S. S&P 500 Stock (SP), Vanguard Total World Stock Index Fund (VT), Bitcoin (BTC), Ethereum (ETH), Ripple, OIL, and...

Research background: Algeria heavily relies on its oil revenues, being one of the leading crude oil producers in Africa and a key member of OPEC. This dependency exposes its economy to the volatility of oil prices in international markets, which can have significant repercussions on its...

This paper applies the R² connectedness method proposed by Balli et al. (2023) to analyse contemporaneous and lagged connectedness between returns on several asset classes (sector ETFs, Bitcoin, stock market indices, Brent crude oil) over the period 1 January 2023 – 22 September 2025, in the...

The recurrence of international geopolitical events has intensified tensions in global energy supply chains. As a major crude oil consumer, China urgently needs to identify vulnerabilities within its crude oil supply chain (COSC) and implement targeted measures to safeguard national energy...

The Islamic Republic of Mauritania will soon commence gas production through the Grand Tortue Ahmeyim, a major natural gas development situated offshore between Mauritania and Senegal. This mission assessed the current situation of the management of the hydrocarbon tax revenues and provided...

Amid the growing debate over how cryptocurrencies are reshaping global finance, this study explores the nexus between Bitcoin, Brent Crude Oil, Gold and the U.S. Dollar Index. We used a time-varying vector autoregressive (tvVAR) model to examine the connection among these four assets during the...

We investigate the impact and propagation of geopolitical risk among oil-based energy commodities. First, we endogenously identify key geopolitical events affecting the connectedness among the oil-based commodities and then evaluate their transitory and persistent impacts. We identify four major...

Oil prices have been increasingly volatile since 2004. However, the impact of this volatility on domestic end-user prices differs significantly by fuel and country. Some countries fully pass through global price movements to domestic end-user prices, and some countries freeze domestic fuel...

The rapid growth of US ethanol production, driven by the Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007, has raised questions about intensifying price linkages between energy and food markets. This is based on the premise that higher crude oil prices incentivize...

This study employs asymmetric quantile regression to investigate the asymmetric impact of WTI crude oil prices and economic policy uncertainty (EPU) on stock market returns from May 2014 to December 2024 in oil-importing (China, India, Germany, Italy, Japan, USA, and South Korea) and...

We investigate linkages between three different markets: renewable energy (represented by a range of renewable energy ETFs); traditional energy (represented by crude oil ETF); and common stocks (represented by the S&P 500 Index ETF). We use daily data from 2008 to 2021. The econometric framework...

This study examines the simultaneous relationships among oil prices, oil volatility, and two sub-sectors within alternative energy stocks: renewable energy equipment (REE) and alternative fuels (AF). The results confirm the existence of a bidirectional relationship. While most alternative energy...

Geopolitics is an overarching characteristic of much of this outlook for the key themes in the global energy economy in 2025. The start of Donald Trump’s second term in the White House will herald new pressures to multiple layers of the global economy, from trade to labour, monetary policy to...

To reduce funds for Russia’s Ukraine invasion, Western governments imposed a price ceiling on Russian seaborne oil exports using Western services. To sell above that ceiling, Russia developed a “shadow fleet” which uses no such services. We use a calibrated model driven by this fleet’s...

To ensure energy security for emerging economies, it is imperative to explore the impacts of economic policy uncertainty (EPU) and geopolitical risk (GPR) on oil imports in China (COI) and India (IOI). An innovative wavelet quantile correlation framework is devised to dissect EPU-COI, GPR-COI,...

In popular Baba-Engle-Kraft-Kroner (BEKK) and dynamic conditional correlation (DCC) multivariate generalized autoregressive conditional heteroskedasticity models, the large number of parameters and the requirement of positive definiteness of the covariance and correlation matrices pose some...

The global crude oil trade network, a cornerstone of energy supply chains, suffers from structural inefficiencies that amplify environmental damage and geopolitical risks. This study aims to (1) develop an optimization model reconciling logistical costs with CO2 emissions, (2) quantify energy...

This current paper evaluates the variational dependence between West Texas Intermediate (WTI) crude oil and stock returns in the automotive sector, encompassing those operated in New York (Tesla, Toyota, Volkswagen, and Honda) and Shanghai (Chongqing, Build Your Dream [BYD], Jianghuai Automobile...
