CHUR, Switzerland, May 10 (Reuters) - Swiss National Bank Chairman Thomas Jordan reiterated on Wednesday that the central bank could not rule out raising interest rates further, saying current monetary policy was still not restrictive enough.

Delivering a speech on inflation and monetary policy challenges, Jordan noted that inflation was still above the central bank's price stability range and was higher than what policymakers would like it to be.

"The current monetary policy is still not restrictive enough," Jordan said, echoing remarks made last Friday.

Swiss annual inflation edged down to 2.6% in April from 2.9% in March, data showed on Friday, and it is much lower than in many countries where inflation rates have reached double digits.

Still, price growth remains considerably above the central bank's 0%-2% target range, which it has been overshooting since February 2022, prompting Swiss policymakers to raise rates at its last four quarterly meetings.

It will next review interest rates on June 22 and many analysts expect it to notch up borrowing costs at least one more time.
