Wall Street falls as oil prices and Treasury yields hit 19-year highs

Jornal Económico15 September 2026 at 15:26

Wall Street opened Tuesday in negative territory, with the S&P 500 falling 0.20%, the Dow Jones losing 0.52% and the Nasdaq Composite down 0.26%. The decline was driven by rising oil prices and increasing Treasury yields, with the 10-year US debt interest rate reaching levels not seen in about 19 years.

Investors are cautious ahead of upcoming communications from the Federal Reserve, seeking signals about the monetary authority's response to a potential resurgence of inflation. The possibility of a more restrictive monetary policy has weighed on risk assets. The worsening of tensions in the Middle East increases the risk of new disruptions in the oil market and greater pressure on prices, reigniting inflation concerns.

In the technology sector, Nvidia rose 0.94%, with CEO Jensen Huang participating in a panel during which he received a live call from President Donald Trump, who rejected concerns about AI risks, classifying them as a "hoax". Cryptocurrency-linked companies are among the most pressured, with bitcoin falling more than 3% from the high near $79,500 reached on Monday, while Coinbase, Robinhood and Strategy fell more than 4%.

The US Senate is expected to vote Tuesday afternoon on the cryptocurrency regulation bill, known as the Clarity Act, at a time when expectations for approval this year have diminished. Investors should remain cautious while assessing the impact that a potential persistence of inflationary pressures may have on monetary policy and stock valuations.

Why this matters

Domestic investors with exposure to US markets face greater volatility and risk, with the possibility of losses in their equity and cryptocurrency investments. The rise in Treasury yields may pressure financing costs and affect the expected profitability of risk assets, in a context of uncertainty about the Fed's response to persistent inflationary pressures.

European Union Court decided: these workers were dismissed in 1993 and are entitled to compensation 33 years later

The Court of Justice of the European Union decided on 8 September that former Air Atlantis workers, dismissed in 1993, are entitled to compensation from the Portuguese state for judicial errors. The workers accepted compensation for the dismissal believing the closure was inevitable, but were unaware that TAP, the main shareholder, would take equipment and continue part of the operations. The CJEU identified errors in the interpretation of European rules by the Portuguese Supreme Court of Justice and concluded that this court should have requested clarifications from the European court. The decision does not set amounts nor establish deadlines, and it now falls to Portuguese courts to verify whether the violation was sufficiently serious to justify reparation.
