Wall Street stumbled before the bell on Tuesday following a rally the previous day, driven by heavy buying of tech shares as investors bet the Federal Reserve will trim its rate hikes as it makes headway in tamping down inflation.

Futures for the benchmark S&P 500 and futures for the Dow Jones Industrial Average each slipped about 0.3% early Tuesday.

Over the past few years, a number of companies have attempted to act as the cryptocurrency equivalent of a bank, promising lucrative returns to customers who deposited their bitcoin or other digital assets.

In a span of less than 12 months, nearly all of the biggest of those companies have failed spectacularly. Last week, Genesis filed Chapter 11, joining Voyager Digital, Celsius and BlockFi on the list of companies that have either filed for bankruptcy protection or gone out of business.

Markets were slightly higher on Wall Street ahead of the bell Monday as investors prepare for another big slate of corporate earnings.

Futures for the Dow Jones industrials and futures for the S&P 500 were both up less than 0.2%.

U.K. Prime Minister Rishi Sunak opened an investigation Monday into allegations that the chairman of the governing Conservative Party settled a multimillion-dollar unpaid tax bill while he was in charge of the country's Treasury.

The French government is presenting a bill on Monday that foresees broad changes to the pension system that will notably push back the legal retirement age from 62 to 64.

Much of Pakistan was left without power for several hours on Monday morning as an energy-saving measure by the government backfired. The outage spread panic and raised questions about the cash-strapped government's handling of the country's economic crisis.

Electricity was turned off across Pakistan during low usage hours overnight to conserve fuel across the country, officials said, leaving technicians unable to boot up the system all at once after daybreak.

Iraq's prime minister on Monday replaced the governor of the country's Central Bank following a weekslong plunge of the Iraqi dinar, the state news agency reported.

Prime Minister Mohammed Shia al-Sudani made the move after the governor, Mustafa Ghaleb Mukheef, told him he no longer wishes to stay in the job, the Iraqi News Agency said. Mukheef, who was in the post since 2020, was replaced by Muhsen al-Allaq, a former central bank governor, the agency added.

European investigators will question Lebanon's central bank chief Riad Salameh next month as part of a probe into his and his brother's affairs, a judicial official told AFP.

A European legal team has wrapped up the first round of questioning of Lebanese bankers and current and former Central Bank officials in Beirut. The questioning is part of a probe on money laundering linked to Lebanon's Central Bank Governor Riad Salameh.

The European judicial delegation -- with representatives from France, Germany, and Luxembourg -- questioned nine people this week, including current and former central bank officials as well as the heads of several commercial banks, several Lebanese judicial officials told The Associated Press.

Lebanese bankers are giving testimonies that have started nearing the extent of “confessions” in the investigations that are being carried out in Lebanon by three European delegations as part of a probe into Riad Salameh’s wealth, a media report said.
