Wall Street Rallies as US-Iran Deal Triggers Oil Slump and AI Surge

Global financial markets surged on Monday following a tentative agreement between the United States and Iran to extend a ceasefire and reopen the strategic Strait of Hormuz. This diplomatic breakthrough has significantly lowered crude oil prices and reignited investor confidence across the technology and travel sectors.

Oil Prices Tumble on Geopolitical De-escalation

The most immediate impact of the US-Iran agreement was felt in the energy markets. Brent crude oil prices plummeted by 4.8% to $83.18 per barrel, marking a significant retreat from the $100-plus levels seen just weeks ago. While prices remain above the pre-conflict level of $70, the sharp decline has provided much-needed relief to markets concerned about inflationary pressures.

The agreement, which is expected to be formally signed this Friday in Switzerland, aims to restore the flow of crude oil through the Strait of Hormuz. While industry observers caution that it may take months for energy flows to fully normalise, the immediate reduction in energy costs is expected to ease the burden on households and businesses facing high prices for fuel and fertilisers.

Travel and AI Stocks Lead the Wall Street Rally

Wall Street responded aggressively to the news, with the Nasdaq Composite climbing 2.3% and the S&P 500 rising 1.5%. The Dow Jones Industrial Average also saw a substantial gain of 638 points, or 1.2%.

Two specific sectors drove this momentum:

• Travel and Aviation: Companies with high fuel sensitivity saw massive gains. American Airlines climbed 7%, Carnival advanced 5.7%, and United Airlines rose 5.2%.
• Artificial Intelligence: After recent volatility, AI-linked stocks regained ground. Micron Technology jumped 7.8%, Advanced Micro Devices (AMD) rose 7%, and Nvidia advanced 2.7%. Notably, SpaceX—Elon Musk’s rocket company—climbed 5.4% in its second day of trading, with its valuation now exceeding $2.1 trillion.

Easing Inflationary Fears and Bond Market Shifts

The drop in oil prices has had a direct impact on the bond market and expectations regarding US monetary policy. As concerns over energy-driven inflation subside, Treasury yields have eased, with the 10-year Treasury note falling to 4.45% from 4.48%.

Esta mudança é crucial, pois o mercado aguarda a decisão de política do Federal Reserve dos EUA esta semana. De acordo com dados do CME Group, os traders ajustaram significativamente suas perspectivas: a probabilidade de um aumento de taxa este ano caiu para 55%, abaixo dos 71% de apenas uma semana atrás. Essa mudança sugere que a narrativa de taxas de juros "mais altas por mais tempo" (higher-for-longer) pode estar perdendo força à medida que as tensões geopolíticas diminuem.

Mercados Globais Seguem a Liderança dos EUA

O otimismo não se limitou aos EUA. Na Ásia, o Nikkei 225 do Japão subiu 5%, atingindo um recorde histórico, enquanto o Kospi da Coreia do Sul subiu 5,2%, impulsionado por gigantes da IA como a Samsung Electronics. Analistas sugerem que as compras de investidores estrangeiros estão impulsionando essas altas, alimentadas pela expectativa de estabilização das tensões no Oriente Médio.

Principais Conclusões

• Alívio na Energia: O petróleo Brent caiu 4,8%, para US$ 83,18, após o acordo de cessar-fogo entre EUA e Irã, aliviando as preocupações inflacionárias globais.
• Setores Vencedores: Ações de viagens (American Airlines +7%) e líderes de IA (Micron +7,8%) lideraram o rali do mercado.
• Mudança na Política Monetária: A probabilidade de um aumento das taxas de juros nos EUA este ano caiu de 71% para 55%, à medida que os custos de energia se estabilizaram.
