Confidence among big nonmanufacturers also recovered from three months ago, underscoring the fading strains from the coronavirus pandemic, a central bank survey showed on Thursday.

The data offers some relief for policymakers striving to revitalize the pandemic-hit economy as a fourth wave of infections raises uncertainty about the outlook.
