Regulators are singling out a trade on Deutsche Bank AG’s credit default swaps that they suspect fueled a global sell off on Friday.

It was a roughly €5 million ($5.4 million) bet on swaps tied to the German bank’s junior debt, according to people familiar with the matter, who said regulators have spoken to market participants about the transaction. The contracts can be illiquid, so a single bet can trigger big moves. A spokesperson for Deutsche Bank declined to comment.
