Hawk
A central banker, or economic advisor, whose policies are being primarily concerned with interest rates. Hawks tend to be in favour of keeping interest rates relatively high in order to keep inflation down. Hawk’s policies are not as concerned with economic growth as they are with keeping inflationary pressures in check. Policies or statements made to this effect are described as being “hawkish”.
