NASDAQ OMX expands Clearing House offering to repos - First repo transactions between Danske Bank, Nordea, SEB, Swedbank and Handelsbanken cleared

Stockholm, October 7, 2010 — NASDAQ OMX (NASDAQ:NDAQ) announces that it has     
launched a clearing service for the repo market together with market            
participants. As a result of an agreement between the Swedish Money Market      
Council and NASDAQ OMX, the entire Swedish Interbank repo market will ultimately
be cleared through NASDAQ OMX Stockholm AB.                                     

Previously, SEK denominated repos, a market with an average total daily turnover
of more than 100 billion SEK (~USD14 bn), have been traded and settled          
bilaterally. The introduction of a central counterparty reduces counterparty    
risk and increases transparency, thereby improving financial stability. In      
addition, clearing will increase liquidity on the Swedish repo market and the   
underlying bond market, as market participants benefit from positive effects    
from reduced credit exposures as well as netting.                               

“The agreement with the Money Market Council changes the structure of the       
Swedish repo market and will make central clearing an industry standard for the 
Swedish repo market. This is an important step in the expansion of our clearing 
house offering to further OTC products” says Erik Thedéen, Head of Nordic Fixed 
Income and President NASDAQ OMX Stockholm.                                      

“The introduction of central clearing in the Swedish repo market is a milestone 
when it comes to improving the Swedish bond market. Central counterparty        
clearing will limit counterparty risk and further increase the attractiveness of
the Swedish Fixed Income markets”, stated Tomas Hedberg, Chairman of the Swedish
Money and Bond Market Council and Head of FX & Fixed Income at Swedbank.        

The first interbank repo transactions have now been successfully registered for 
clearing and settled accordingly. The service will, via our members, also be    
available for end-customers such as asset managers and corporate treasury       
departments.                                                                    

About repos                                                                     
A repurchase agreement, or a repo, is a single agreement to sell a security on a
start date and buy it back again from the same counterparty on the end date at  
an agreed price. The same agreement is a reversed repo for the buyer. In simple 
terms, repos are borrowing/lending of cash with securities transferred as       
collateral during the borrowing/lending period.                                 

The repo market provides banks and other market participants a possibility to   
secure short term funding at the same time as the market is offering investment 
alternatives for asset managers. The existence of an efficient repo market      
supports the efficiency of the underlying bond market and in the long run       
ensures efficient pricing in the bond market, as bond market makers often rely  
on the repo market to cover the settlement of a bond.
