Norwegian companies expect economic growth to slow in the coming six months, a central bank survey showed on Tuesday, driven by high inflation, capacity constraints and expected higher interest rates dampening demand.

"Constraints have become increasingly widespread across all sectors in the course of spring, except retail trade where somewhat more enterprises now have spare capacity," Norges Bank said in a statement.

The quarterly survey provides key input to monetary policy. The central bank has said it would most likely raise interest rates on June 23, with a string of more hikes to come. (Reporting by Gwladys Fouche, editing by Victoria Klesty)
