NASDAQ OMX Stockholm Launches Futures Contract Based on the Swedish Central Bank's Repo Rate

First exchange in Europe to offer futures contract clearing linked to the
Central Bank's repo rate 

Stockholm, April 15 , 2009 - NASDAQ OMX Stockholm, part of NASDAQ OMX Group, 
Inc., (NASDAQ: NDAQ) announced today that it will be the first exchange in      
Europe to launch a policy rate futures contract - RIBA - based entirely on the  
repo rate set by Riksbanken, the Swedish Central Bank. The RIBA contract will   
enable investments based on expected trends in the repo rate, and will be traded
with central counterparty clearing. RIBA is introduced today April 15.  

“The Central Bank's monetary policy is critically important to interest rate    
levels in the capital market, and our Riksbank future contract, RIBA, will make 
it possible to interpret market expectations with regard to key interest rates. 
The information will benefit both home buyers and asset managers. In the wake of
the financial crisis, we have noted an increased focus on efforts to lower      
counterparty risks and, accordingly, we will serve as the counterparty both for 
buyers and sellers of RIBA,” stated Erik Thedéen, President of NASDAQ OMX       
Stockholm.                                                                      

“Members of the Money Market Council look forward to working with NASDAQ OMX in 
extending offers to trade against the Swedish Central Bank's repo rate,” stated 
Erik Ekman, Chairman of The Swedish Money Market Council. “We see excellent     
potential for favorable trading in RIBA, and our members have jointly agreed to 
actively support liquidity in the contracts.”                                   

RIBA will be traded in the over-the-counter market, off the stock exchange.     
NASDAQ OMX Stockholm has signed contracts with a number of market makers,       
including Danske Bank, Nordea, RBS, SEB, Svenska Handelsbanken and Swedbank that
have agreed to maintain and ensure a favorable level of liquidity in RIBA.      
Trades in RIBA contracts will be reached through bilateral negotiations between 
buyers and sellers, and reported to NASDAQ OMX Stockholm for central            
counterparty clearing.                                                          

RIBA is a cash-settled futures contract with a term corresponding to the period 
between two IMM (International Money Market) dates, and computed for final      
settlement based on the average repo rate for a given period of time. The       
contract base is a fictitious loan with a nominal value of SEK 1 million.       

This is how RIBA works                                                          
When a RIBA contract is purchased, the buyer assumes the obligation to          
(fictitiously) borrow money at the interest rate agreed upon by the buyer and   
seller, and which meets both parties' anticipated future repo rates. If the repo
rate at maturity exceeds the agreed interest rate, the buyer receives the       
interest difference. Accordingly, buyers of RIBA contracts make money if the    
interest rate increases.                                                        

When a RIBA contract is sold, an obligation arises to lend money (fictitiously) 
at the interest rate agreed upon by the buyer and seller. If the repo rate at   
maturity is lower than the agreed interest rate, the seller receives the        
interest difference. Accordingly, sellers of RIBA contracts make money if the   
interest rate declines.
