Markets between war and diplomacy: Brazil in shock, Wall Street bets on artificial intelligence
On the one hand, diplomatic efforts in the Middle East have fueled hopes of an easing of energy tensions; on the other, renewed attacks, political instability, and fiscal concerns have reminded us of how fragile the balance remains. Meanwhile, American stock markets have found support in artificial intelligence, while Brazil has experienced a market shock and Europe has shown signs of growing vulnerability.
Middle East: Diplomacy Meets Energy Risk
The talks launched in Tehran between Iran, Saudi Arabia, Turkey, and Pakistan have reopened a diplomatic window in a conflict that continues to impact the global economy. Tehran, however, maintains specific conditions: the reopening of the Strait of Hormuz remains tied to the lifting of the US naval blockade and broader guarantees of an end to hostilities.
The gap between diplomacy and real security remains significant. The Houthis have claimed new attacks against Saudi infrastructure, including energy targets and Riyadh airport. Brent crude, despite falling back towards $114 a barrel in Tuesday's trading, continues to carry a significant geopolitical premium. Elections in Israel could also alter regional balances and the approach to the war.
On the Ukrainian front, the local humanitarian truce in Oleshky and contacts between Nordic leaders and Moscow signal limited openness. Russian bombings in other cities, however, remind us that this is not a general turning point in the conflict.
For Europe, the risk is immediate. TTF gas has approached 97 euros per megawatt-hour , driven by difficulties in LNG supplies and concerns about winter stocks. Expensive energy means pressure on industrial margins, consumption, and central bank decisions. Gold, meanwhile, has risen to around $4,057 an ounce , reflecting both the search for protection and rapidly shifting interest rate expectations.
Brazil rediscovers the price of political uncertainty
The re-election of Luiz Inácio Lula da Silva triggered a particularly violent reaction on Brazilian markets. The Bovespa index lost 13.9% in a single session, and the real depreciated 8.1% against the dollar, reaching approximately 5.415 reais per dollar. This marked a sharp reversal of the bets placed on a possible change of government.
The issue is not only political, but above all fiscal. Market participants seek credible indications on the composition of the next economic government, debt containment, and the sustainability of social promises. When these answers are lacking, investors demand higher returns to finance the government and reduce their exposure to local currency-denominated assets. The Brazilian case illustrates how political expectations can quickly translate into financial volatility.
Wall Street holds firm, Europe remains more exposed
In the United States, the climate was markedly different. The S&P 500 closed up 0.7% on Monday, while the Nasdaq had gained nearly 0.98% in afternoon trading on Tuesday. Buying was primarily driven by earnings expectations from major technology companies and the temporary decline in oil prices. However, high bond yields and a cautious Federal Reserve on inflation remain.
In Europe, however, after an initial recovery in the STOXX 600 index to near 0.8% , renewed hesitations emerged, accentuated by HSBC's disappointing results and French political tensions. Moody's maintained France's rating, but did not remove its negative outlook: a sign that distinguishes the solidity of institutions from the still-unresolved budget problems. French consumer confidence fell to 80 points , confirming the weakness of domestic demand and the impact of the protests.
The combination of expensive energy, high financing costs, and fiscal uncertainty remains particularly unfavorable for a continent struggling to find widespread growth.
Asia: Technology fuels a multi-speed economy
Better signs are coming from Asia, but they're not uniform. In South Korea, gross domestic product grew by 1% quarterly and 3.4% annually , thanks primarily to global demand for semiconductors and new manufacturing investments.
In China, industrial profits also rose 14.4% in September, accelerating from 4.2% the previous month. The overall figure, however, masks significant differences: electronics and artificial intelligence-related sectors are progressing, while consumer-oriented and domestic demand-driven sectors continue to struggle. Beijing must therefore reconcile industrial competitiveness with a rebalancing of consumption, ensuring that expansion is not concentrated in a few supply chains.
Artificial Intelligence: Immense Capital, Expectations to Be Delivered
Artificial intelligence remains the dominant theme for global investors. Anthropic has filed paperwork for a potential IPO, with market valuations of up to $2 trillion . This isn't yet a final price, but it indicates the scale of expectations placed on new digital models and services.
Meta, meanwhile, has expanded its equity raising plan to $97.5 billion to finance infrastructure and computing capacity. This is a crucial step: the race to AI requires physical investment, energy, and significant financial resources, not just software innovation. Growth potential remains considerable, but questions about return on invested capital, shareholder dilution, and the time required to turn expenditures into profits are also growing.
Outlook: Strong, but increasingly selective markets
The overall scenario is one of markets capable of responding positively to technological prospects, but vulnerable to political and energy shocks. Diplomacy will need to produce verifiable results, and AI will need to generate sustainable cash flows.
For investors, the key is not chasing every swing, but distinguishing structural trends from fleeting enthusiasms. In a time when geopolitics, energy, and technology are mutually influencing each other, earnings quality and financial strength are once again becoming crucial.
