Berkshire Hathaway's Warren Buffett said Tuesday the U.S. economy is growing at about 2 percent, a rate he characterized as not bad.

"We're still on that path we've been on for six years," the chairman and CEO of Berkshire Hathaway said on CNBC's "Squawk Alley." "That's not a bad rate, but it's not a booming rate, either."

Buffett made his remarks as investors around the world ponder whether or not the Federal Reserve will move forward on raising interest rates, given the recent volatility in financial markets.

"If our rates got substantially higher than Europe's, I don't think that would be good for exports in this country," Buffett said. "In economics, you can never do one thing. There is always a 'then what' and I think the 'then what' of raising rates while Europe's trying to keep them low could have some consequences down the line."
