The recent scandal surrounding Nomura Securities Co. will not affect current efforts to implement the "Big Bang" financial system reforms, the acting head of the Japan Securities Dealers Associations said.

Tsugio Yukihira, who assumed the acting chairmanship of JSDA after Nomura Chairman Masashi Suzuki resigned over the scandal last week, called the whole affair involving the nation's top brokerage and payoffs linked to a "sokaiya" corporate extortionist "regrettable." Speaking Mar. 19 at his first news conference as head of the industry group, Yukihira, also chairman of Yamaichi Securities Co., said the association would also consider taking punitive action against Nomura if investigations prove any wrongdoing. "But the incident will not, and indeed must not, affect the reform process. It will be handed as a separate issue," he said.

Yukihira added that he was confident his own firm was not involved in similar transactions with racketeers as some media reports say, or he would not have assumed the post of acting chairman. He will hold the post until the end of June, after which he is expected to become chairman. JSDA will swiftly consider new self-regulatory steps to prevent such incidents after the results of the authorities' probes are released, he added.
