Monetary policy in this case can help to avoid a permanently weaker equilibrium (say with unemployment too high and inflation and inflation expectations too low), in which case the bond purchase program can have a persistent effect on yields, even once it has ended; like the first case, additional policy support helps to restore the equilibrium that existed prior to the adverse shock.
Given that the resources sector is largely foreign-owned, this would be accompanied by an increase in dividend payments to foreign investors (an outflow on the net income component of the current account). Although the resources sector’s transition from investment to production will likely result in a reduction in net capital inflows to the sector, the effect on the Australian dollar is more nuanced.
