Deutsche Bank today has announced that it will redeem all outstanding shares of the PowerShares DB Crude Oil Double Long (DXO). In a statement, Deutsche Bank said that limitations imposed by the exchange on which the exposure of the notes is managed have resulted in a “regulatory event,” leading to the redemptions.

No other ETNs are impacted by the announcement. No exchange traded funds (ETFs) offered by Deutsche Bank affected. The bank said it will redeem all shares on Sept. 9, and it will determine the “repurchase value” .

The decision comes amid speculation that the Commodity Futures Trading Commission (CFTC) is going to clamp down on positions these products can take, reports Carolyn Cui for The Wall Street Journal. DXO’s closure is the first casualty of the scrutiny these funds have been under in recent months.

Cui notes that the closure could temporarily send oil prices lower as the managers sell all the oil contracts.
