Markets appeared to sigh in relief after the Federal Reserve got no closer to raising rates in its latest policy statements, but Marc Faber said there should be no need to worry about any interest rate increase.

"I doubt they would increase rates this year. I think they'll keep rates at essentially zero," Faber said Wednesday in a "Trading Nation" interview. "[Fed Chair Janet] Yellen said very clearly that the rate hikes are data-dependent, and data is globally getting worse, it's not getting any better."

To Faber's mind, America is in dire straits.

"I don't think the U.S. economy is doing particularly well," the editor and publisher of the Gloom, Boom & Doom Report said. "One of the problems is affordability, and cost-of-living increases. For most households, the cost of living has gone up very substantially and so their spending power is limited. In addition to that if you look at tax revenues in the U.S., corporate tax as a percent of GDP is essentially flat. However, what has gone up a lot as a percent of GDP is individual taxes, so it has some negative impact on the economy."
