London copper prices held steady on Wednesday on signs of easing Russia-Ukraine tensions, offsetting pressure from expectations of an aggressive interest rate hike by the US central bank.

Three-month copper on the London Metal Exchange (LME) was little changed at $9,971 a tonne, as of 0325 GMT, while the most-traded March copper contract on the Shanghai Futures Exchange rose 0.8% to 71,460 yuan ($11,269.87) a tonne.

On Tuesday, Russia said it was returning some troops to base after exercises, boosting sentiment in financial markets.

Meanwhile, data showed US producer prices increased by the most in eight months in January in another sign of high inflation. Financial markets have priced in a better-than-even chance that the Federal Reserve will raise interest rates in March by half a percentage point.
