March 3 (Bloomberg) -- The U.S. is asking hedge funds not to destroy trading records on euro bets, according to a person with knowledge of the requests, as Europe and the U.S. step up scrutiny of the funds’ role in the Greek debt crisis.

The Department of Justice sent requests to save the records to at least some of the hedge funds whose executives attended a dinner hosted by New York-based research and brokerage firm Monness, Crespi, Hardt & Co. on Feb. 8, said the person, who declined to be identified because the information is private.

The European Commission said yesterday it will investigate trades in sovereign credit-default swaps in the wake of the Greek crisis, which has pushed the euro lower and prompted officials to warn hedge funds they shouldn’t try to profit from the woes of the region’s nations. One of 23 themes discussed at the Feb. 8 dinner was a wager that the euro would fall against the dollar, according to an agenda obtained by Bloomberg News.

Futures traders last week placed the biggest bets on record that the euro will fall against the dollar. The number of wagers by hedge funds and other large speculators for a decline in the 16-nation currency rose on Feb. 23 to 71,623 contracts more than those anticipating a gain, according to Commodity Futures Trading Commission data. It was the fourth consecutive week that the amount climbed to a record.

Even if the Department of Justice decides to request the records it has asked the hedge funds to save, that doesn’t necessarily mean that the managers will be investigated , said Jedd Wider , a partner at law firm Morgan, Lewis & Bockius LLP.

Bullish on Canada

Other ideas discussed at the dinner, which took place at the Townhouse, a private facility run by restaurant Park Avenue Winter, were bullish bets on the Canadian dollar and Philip Morris International and bearish wagers on Wells Fargo & Co. and Bank of America Corp .
