Private equity has pumped $32 bln into shipping in past 2 years. Ships totaling 299 mln dwt to enter global fleet from May. Some private equity-backed shipping IPOs have been put off on weak sentiment. The shipping industry faces a looming capacity glut as billions of dollars pumped into it by private equity have stoked a vessel-buying spree, threatening its prospects just as the sector is emerging from its worst downturn in three decades. Backed by private equity and hedge fund financing, shipping companies have placed orders for thousands of new ships over the past two years, reminiscent of the ship-ordering binge of the mid-2000s that eventually led to overcapacity after the global financial crisis severely hit cargo demand.
