As optimists see green shoots of recovery, inflation worriers are hitting the panic buttons and calling for spending restraint even amidst the worst recession since the 1930s. Deutsche Bank Research says rarely has the inflation outlook given rise to such differences in opinion as today. While some experts - - including the OECD - - warn against deflation, others believe inflation will accelerate strongly in the medium run. It says, to be sure, monetary and fiscal policies are currently moving in unknown territory so - - of course - - caution is advised in the analysis. However, it considers worries about inflation to be exaggerated, even on a 3 to 5-year horizon.
