BERN, Dec 14 (Reuters) - The Swiss National Bank held its policy interest rate steady at 1.75% on Thursday, kicking off a busy day for central banks around Europe, which are also expected to pause following their monetary policy tightening campaigns after inflation ebbed.

The Swiss central bank, which over the last 18 months had raised rates from negative 0.75% before pausing in September, also kept its interest rate on sight deposits at 1.75%.

The decision to hold interest rates had been expected by all 31 economists surveyed in a Reuters poll.
