State Street wants to launch actively managed exchange traded funds next year, according to a report.

“We hope to introduce our first set of active ETFs in 2012,” Jim Ross, global head of ETFs at State Street Global Advisors, told Mutual Fund Wire. “The initial set is probably going to be a suite of five to six active ETFs rolled out over a few months.”

SSgA manages the biggest and oldest ETF, SPDR S&P 500 (NYSEArca: SPY), which was introduced in 1993 and holds about $94 billion in assets. The firm is the second-largest ETF manager in the U.S. with $264.5 billion in assets at the end of November, according to National Stock Exchange data.

A recent report by McKinsey & Co. predicts that the actively managed exchange traded fund business will take off and hit the $1 trillion mark within a decade. Currently, active funds represent only a tiny fraction of the overall business. [Active ETFs]

“It’s a question of when, not if, active ETFs will be part of the landscape,” said Tony Rochte, head of the North American intermediary business group at SSgA. [Index ETFs Still Rule]

Separately, State Street has filed to launch a pair of new fixed-income ETFs. The company is readying a breakeven inflation ETF and a commercial paper fund that strips out the financial sector, according to the filing.

The “breakeven” rate of inflation is the level of inflation required for Treasury Inflation Protected Securities (TIPS) to approximate the performance of U.S. Treasury securities with equivalent duration, according to the filing. The tracking index takes long positions in TIPS and shorts traditional Treasury bonds.
