David Stockman has long warned that the stock market is on the verge of a massive collapse, and the recent price action has him even more convinced than ever that the bottom is about to fall out.

"I think it's pretty obvious that the top is in," the Reagan administration's OMB director said Thursday on CNBC's "Futures Now." The S&P 500 has traded in a historically narrow range for the better part of 2015, having moved just 1 percent higher year to date. "It's just waiting for the knee-jerk bulls, robo traders and dip buyers to finally capitulate."

Stockman, whose past claims have yet to come to fruition, still believes that the excessive monetary policy from central banks around the world has created a "debt supernova," and all the signs point to "the end of the central bank enabled bubble," which could cause a worldwide recession.

"The larger picture has nothing to do with the jobs report [Friday] or even the September decision by the Fed," said Stockman. "It has to do with the the fact that the world economy, including the U.S., is heading into what is clearly going to be an epochal deflation to the likes of what we have never experienced in modern time."

According to Stockman, it's only a matter of time before the collapse in trickles down to other markets. "The whole global economy since 2008 has been driven forward by this massive investment and construction and borrowing spree in China," said Stockman. "The point that I'm making is that it's over."

For Stockman, there's no reversing the artificially inflated bubbles created by the Federal Reserve. "I think what we are seeing is the beginning evidence that the central bank-driven credit economy is over and we are in a new era," said Stockman. "It's a huge disaster waiting to happen."
