UPDATE 1 — Swedish central bank holds rates unchanged at 1.75%

(Adds Riksbank comment in paragraph 2) STOCKHOLM, Sept 24 (Reuters) — Sweden's central bank kept its key policy interest rate unchanged at 1.75% as expected on Thursday but said the policy rate should be raised more going forward than had been projected in its June forecast. "If the outlook for inflation and economic activity remains unchanged, it is expected that the increases to the policy rate will begin this year," the Riksbank said in a statement. Analysts in a Reuters poll had been unanimous in seeing no change this time. The Riksbank has been growing increasingly worried about the chance inflation will pick up after higher-than-expected readings during the summer. Norway's central bank will announce its policy decision later in the day with a small majority expecting a hike to 4.50%.
