Oil, Debts, and Markets: The World Under Tension

On September 2, 2026, oil prices soared after US strikes in the Middle East, while Wall Street closed sharply lower. This dual movement illustrates a fragile global economy, where geopolitics and finance are more intertwined than ever. Investors must navigate an environment marked by high sovereign debts, extreme energy volatility, and contradictory signals on growth.

Key Points

Rising oil prices and geopolitical tensions: US strikes in Iran drove up the price per barrel, increasing fuel costs. In the Netherlands, the price of gasoline reached an all-time high of 2.668 euros per liter, while in Quebec, it stood at 1.89 dollars. American refiners, summoned to the White House, saw their profits quadruple thanks to the conflict.
Sovereign debt: a growing burden: 2031 projections show high net debt levels in Japan (122.8% of GDP), Italy (126.7%), and France (112.6%). The United States is not far behind with 115.4%, while Germany (60.7%) and South Korea (12.9%) show more sustainable situations.
US housing market in crisis: High mortgage rates and record prices have reduced residential mobility to a historically low level, creating a severe affordability crisis and a “strange” and “dark” market.
Strategic reconfigurations in the mining and energy sector: Tanzania sees its mining model bear fruit, while an American company takes over Venezuelan oil fields held by Chinese and Russian companies, redrawing the map of alliances.
Differentiated growth in emerging economies: Brazil grew by 0.5% in the second quarter, slowing compared to the first, while India showed robust growth of 7.8% in the first quarter of the fiscal year, driven by manufacturing and services.

Context

The current situation is part of a context of emerging from a pandemic crisis and the war in Ukraine, which have left deep marks on public finances and supply chains. Central banks, after pursuing accommodative monetary policies, had to tighten their policies to combat inflation, causing a rise in long-term interest rates. At the same time, geopolitical tensions in the Middle East and Eastern Europe have exacerbated energy price volatility, recalling the oil shocks of the 1970s. Emerging economies, such as Brazil and India, seek to consolidate their growth, while African countries, such as Senegal and Côte d'Ivoire, try to negotiate agreements with international financial institutions to alleviate their debt and support their agricultural sectors.

Key Players

United States: Under the presidency of Donald Trump, the country exerts direct pressure on refiners to lower fuel prices, while conducting military strikes in the Middle East that support oil prices. The independent Federal Reserve must juggle fighting inflation and supporting slowing growth.
China: A major player in global trade and finance, it sees its companies lose assets in Venezuela but continues to invest heavily in infrastructure and green technologies. Its growth, although slowed, remains a key driver for the global economy.
European Union: Faced with high sovereign debt (France, Italy) and stagnant growth (German IFO index at 88.8), it seeks to strengthen its strategic autonomy, particularly in energy and finance. The ECB must manage a 10-year AAA yield curve at 3.34%.
Emerging Economies: India, with 7.8% growth, attracts investments, as evidenced by the sale of Blackstone's stake in EPL and the ECB's approval for Tata Motors' acquisition of Iveco. Brazil, despite a slowdown, benefits from robust agriculture. African countries, such as Senegal and Côte d'Ivoire, are negotiating with the IMF for funding and to stabilize their economies.
International Financial Institutions: The IMF plays a central role in restructuring Senegalese debt, while central banks, like the RBI in India, appoint new leaders to address economic challenges.

Data and Figures

According to institutional data, the net debt of advanced countries will reach peaks by 2031. Japan, with 122.8% of GDP, and Italy, with 126.7%, are the most indebted, followed by France (112.6%) and the United States (115.4%). These levels contrast with South Korea (12.9%) and Turkey (23.0%), which have greater fiscal maneuvering room. In Germany, net debt is 60.7% of GDP, reflecting prudent fiscal management.

According to available public indicators, the German IFO Business Climate Index stood at 88.8 in August 2026, a slight decrease, signaling a deterioration in business confidence. The Eurozone AAA yield curve, measured by the Beta0 parameter, is at 1.427, while the 10-year yield reaches 3.34%, reflecting moderate inflation and growth expectations.

The CNN Fear & Greed Index, which measures investor sentiment, fell from 57.09 on August 28 to 45.57 on September 1, indicating a return of fear to the markets. The gold/copper ratio, often used as a risk aversion indicator, stood at 9780.3 on August 29, suggesting some caution.

In the energy sector, alerts show significant variations in renewable production in France: wind power production in Centre-Val de Loire increased by 26.78%, while hydraulic production in Burgundy fell by 27.14%. These fluctuations highlight dependence on weather conditions and the need to strengthen interconnections.

Crude oil prices experienced notable variations: production in the United Arab Emirates decreased by 26.96%, and in Equatorial Guinea by 27.14%, contributing to the price increase.

Analysis of Issues

In the short term (1-6 months), rising energy prices risk weighing on household consumption and production costs, fueling inflation. Central banks might be forced to maintain high rates, which would curb growth. The US housing market, already in crisis, could worsen, with consequences for the construction sector and regional banks.

In the medium term (1-3 years), high sovereign debt levels limit governments' ability to stimulate the economy in the event of a shock. Emerging countries, such as India and Brazil, could fare well thanks to their growth, but they remain vulnerable to capital fluctuations and geopolitical tensions. Companies, like Tata Motors with the acquisition of Iveco, seek to strengthen internationally, but they must face complex regulatory environments.

Winners in this situation are oil producers and energy companies, who see their profits increase. Losers are consumers, energy-intensive industries, and oil-importing countries. The most affected sectors are automotive, aviation, chemicals, and agri-food, which are highly dependent on energy costs.

However, this picture should be nuanced. Indian growth, for example, is robust, but it relies in part on fiscal stimulus policies and favorable demographics. Debt data are projections, which could be revised based on economic growth and fiscal policies. Moreover, sentiment indicators, such as the CNN Fear & Greed Index, are volatile and can reflect short-term reactions rather than underlying trends.

Forward-looking Assumptions

Scenario 1: Continued monetary normalization and soft landing

If geopolitical tensions ease and inflation continues to fall, central banks could begin to loosen their monetary policies from 2027. Long-term interest rates would decrease, easing the debt burden and stimulating investment. Global growth would stabilize around 3%.

Probability: 40%. Indicators to monitor: evolution of oil prices, business confidence indices, core inflation rate.

Scenario 2: Global recession triggered by an energy shock

If the conflict in the Middle East intensifies and oil prices exceed $150 per barrel, the global economy could plunge into recession. Advanced countries, already indebted, would struggle to implement stimulus plans. Unemployment would rise, and financial markets would collapse.

Probability: 30%. Indicators to monitor: oil stock levels, OPEC+ decisions, central bank reactions.

Scenario 3: Increased divergence between emerging and advanced economies

Emerging economies, such as India and Brazil, could continue to grow rapidly, attracting investments, while advanced countries would face secular stagnation. Capital would flow to emerging markets, but with risks of bubbles and currency crises.

Probability: 30%. Indicators to monitor: capital flows, exchange rates, trade policies.

Why it matters

These economic and financial dynamics have a direct impact on your purchasing power, savings, and employment. Rising energy prices affect electricity and fuel bills, while public debt can lead to tax increases or cuts in public services. Financial markets, influenced by these factors, determine the return on your investments. Understanding these issues allows you to anticipate developments and make informed decisions. As oil prices soar and public debts reach record highs, how will governments and central banks manage to reconcile economic stability and geopolitical imperatives?
