TREASURIES-Yields rise before seven-year auction

* Treasury to sell $28 bln seven-year notes

* Corporate supply weighing on market

* Fed seen closer to paring balance sheet

NEW YORK, July 27 (Reuters) - U.S. Treasury yields rose on Thursday as investors prepared for new debt issuance and evaluated the Federal Reserves statement that it is closer to paring its balance sheet. The U.S. central bank said on Wednesday it expected to start winding down its massive holdings of bonds "relatively soon," despite striking a cautious tone on low inflation. Many analysts and traders expect the Fed to announce its balance sheet reduction plans at its September meeting. The Fed is still in play, said Justin Lederer, interest rate strategist at Cantor Fitzgerald in New York. At the same time, "we have the seven-year note auction ... and theres corporate supply coming to the market, so I think that will weigh on the market a little bit. The Treasury Department will sell $28 billion in seven-year notes on Thursday, the final sale of $88 billion in coupon-bearing supply this week. The United States sold $34 billion in five-year notes on Wednesday and $26 billion of two-year notes to strong demand.
