HONG KONG - Nomura Holdings, Japan's largest brokerage, has reached a deal to buy the Asian operations of Lehman Brothers, according to a source familiar with the matter.

British bank Barclays Plc and Standard Chartered were also said by sources to be vying for the unit. No price was given for the deal.

Lehman Brothers last week filed for bankruptcy protection after collapsing from exposure to risky securities backed by subprime mortgages.

Barclays last week struck a $1.75 billion deal to buy Lehman's core U.S. investment banking business.
