Global markets start a busy week with a sell-off trend, driven by US growth and inflation data, the Jackson Hole Economic Policy Symposium and Nvidia's balance sheet.
Investors entered the week nervously as uncertainties regarding a cease-fire in the Middle East continued to complicate pricing, testing macroeconomics, monetary policy and the artificial intelligence theme simultaneously.

Oil prices maintained their high levels as geopolitical uncertainty persisted over the Strait of Hormuz, which plays an important role in energy supply, keeping concerns about inflationary pressures alive on a global scale.

The data is expected to guide expectations regarding the Fed's interest rate path through the strength of economic activity and the course of inflation.
Financial results to be announced by Nvidia also remained among the important items to follow this week to gauge whether the artificial intelligence theme will continue, in addition to these developments.
Analysts said Nvidia's profitability and growth expectations and its forecasts for the future of the semiconductor sector could increase volatility in the markets.
The tariff issue between the US and Canada was also among the developments occupying the agenda.
Canadian Prime Minister Mark Carney said the US proposed "economically unviable and unfair" conditions in ongoing trade negotiations, adding that Canada will respond in kind to Washington's new tariffs to protect workers, farmers, families and businesses.

Inflation remaining above the ECB's 2% target was among the factors supporting expectations of monetary policy tightening by the bank.
Investors will follow growth and the economic confidence index in Germany, European Central Bank (ECB) meeting minutes on Thursday, the unemployment rate in Germany on Friday and the consumer confidence index in the Eurozone this week.
