The global market for initial public offerings (IPOs) is nearly half the size it should be, the CEO of the Singapore exchange (SGX) Magnus Bocker told CNBC.
"There is no doubt… we have a slowdown in IPOs. If you look long term we are nearly down 40-50 percent," said Bocker, referring to the projected annual growth rate for 2013.
According to Bocker, looking at IPO rates on a historical basis, the global IPO market is falling well short of its projected growth rate this year.
"If you go back to 1990 to 2000 there was a little less than 2,000 IPOs in the world per annum, then in the next ten years we had about 2000 to 2200," he said.
"We should probably be at 2,300 to 2,400 [per annum] for the next ten years. So if you take that as a measure and look at it now, we are at a run rate of around 1,000 to 1,200. I would say we are 40-50 percent down," said Bocker.
