Nomura Holdings (NMR) has been temporarily excluded from taking part in Japanese government debt auctions, the country's Ministry of Finance said Friday.
The suspension of "special entitlements", which will run from Oct. 15 to Nov. 14, comes after the identification of market manipulation by the company of 10-year government bond futures, according to the ministry.
"We take this matter very seriously and apologize to our clients and all other concerned parties for the trouble this has caused", Nomura said in a statement.
