§ I think it is now well understood that, important as monetary policy is as a means of influencing demand generally, it has no special magic for dealing with cost inflation, and it would be inconsistent with my Budget judgment to restrict the growth of money supply so as to reduce demand below the level needed to achieve a growth of output in line with the growth of productive potential. But, equally, the supply of money must not be so plentiful as to produce an additional boost to demand beyond that intention. Nor must it accommodate any further impetus to the rise in costs and prices.
