‘Zero Percent Interest Rates Work’: Pro

What's happening in the stock market appears to be the product of monetary policy more than anything else, Columbia Management CEO Ted Truscott said Thursday.

"I'd boil it down to something quite simple, which is: Zero percent interest rates work," he said. "I used to think that the market was catching up with earnings. Now I think it's zero percent interest rates."

The S&P 500 climbed 14.89 points to close at 1,597.59, earlier hitting a fresh intraday high of 1,598.60.

On CNBC's "Fast Money," Truscott said that the signals were clear.

"Don't fight the Fed. Don't fight the ECB. Don't fight the Japanese Central Bank," he said. "I think people are being pushed into understanding that low interest rates are here for a while."

Truscott also offered saw deflation – or fears of it – as playing a role.

"My own personal view is that they have been battling deflation for quite some time. We haven't seen it, but then again, that's the whole point. You don't want to see it," he said.

"How does it end well? Well, it's going to be a challenge to unwind all this pump-priming, if you will, but I think the real battle has been going on of preventing, essentially, what Japan experienced. I think that's been the play for the last four, five years."
