With persistently low interest rates around the globe, billionaire investor Warren Buffett told CNBC on Monday he'd consider taking money out of banks, especially if negative interest rates result in customers being charged to park their money in accounts.
"There could be a point where you'd really want to start withdrawing currency," Buffett said in a wide-ranging "Squawk Box" interview from Omaha, Nebraska, after he hosted the annual meeting of Berkshire Hathaway shareholders on Saturday.
"If currency in a bank is worth less than currency in your hands ... that could produce something in the way of behavior," he said. "It's a different world. If you have a lot of money in euros, as we do ... you're better off putting it under your mattress than in a bank."
