ProShares has launched the ProShares UltraPro Short 20+ Year Treasury. The ETF now lists on NYSE Arca.

The new offering seeks to provide -3x the daily performance of the Barclays Capital U.S. 20+ Year Treasury Bond Index, before fees and expenses. It is the third ProShares ETF providing inverse exposure to long-term Treasurys.

"Interest in TBT and our other inverse Treasury ETFs has been strong, with many investors concerned about the potential for rising rates," stated Michael L. Sapir, Chairman and CEO of ProShare Advisors LLC, ProShares' investment advisor. "We are pleased to add TTT to our lineup of ETFs for investors seeking to help hedge against or potentially benefit from declines in long-term Treasurys."

ProShares introduced the first inverse Treasury bond ETFs in April 2008. The firm has nearly $5 billion of assets in inverse ETFs on long-term Treasury bonds.
