Jornal Do Brasilia - Wall Street rallies as Fed chief fuels rate cut hopes

Investors had been eagerly waiting for Powell's speech all week, hoping for hints that the Fed would cut rates at its next meeting in September to spur economic growth.

New York's three main indexes surged following his remarks, rebounding after a tech sell-off this week.

European stock markets also advanced in afternoon deals, though the focus there was also on the impact of President Donald Trump's tariffs on the German economy, which shrank in the second quarter.

In his speech at the annual symposium of global central bankers in Jackson Hole, Wyoming, Powell warned that risks of higher inflation and a weakening jobs market meant a "challenging situation".

"Downside risks to employment are rising," Powell said, adding that the effects of Trump's tariffs on consumer prices "are now clearly visible".

"With policy in restrictive territory, the baseline outlook and the shifting balance of risks may warrant adjusting our policy stance," he said.

Powell has come under intense public pressure this year Trump to lower rates -- an unusual political intervention at the independent central bank.

The Fed has kept interest rates steady at a range of between 4.25 percent and 4.50 percent since its last reduction in December.

In keeping rates unchanged, policymakers cited resilience in the labour market as they monitored the effects of Trump's wide-ranging tariffs on the world's biggest economy.

The dollar fell against main currencies as lower interest rates make the greenback less appealing to foreign investors.

Also weighing heavily on investors' minds is the potential for a peace deal in Ukraine more than three years after Russia's invasion.

Oil prices rose slightly on Friday.

Observers have been speculating over how a possible lifting of sanctions on Russia, a major oil producer, would impact markets of the possible lifting of sanctions on Russia, a major producer.

Trump on Thursday set a two-week timeframe for assessing peace talks between Moscow and Kyiv, following days of high-stakes diplomacy that saw him meet with Russian and Ukrainian counterparts in person, as well as several European leaders.

Russian Foreign Minister Sergei Lavrov, however, told NBC television Friday there was "no meeting planned" between the Russian and Ukrainian presidents.

In corporate news, Deutsche Post shares fell 1.2 percent after the German postal service said it would restrict package deliveries to the United States due to Trump's tariffs.
