Note below that he states it’s the fx channel that the ECB is relying on to support aggregate demand.
Good luck to them, it doesn’t work that way!!!
From the speech by Mario Draghi, President of the ECB, Annual central bank symposium in Jackson Hole, 22 August 2014:
Boosting aggregate demand
On the demand side, monetary policy can and should play a central role, which currently means an accommodative monetary policy for an extended period of time. I am confident that the package of measures we announced in June will indeed provide the intended boost to demand, and we stand ready to adjust our policy stance further.
We have already seen exchange rate movements that should support both aggregate demand and inflation, which we expect to be sustained by the diverging expected paths of policy in the US and the euro area (Figure 7). We will launch our first Targeted Long-Term Refinancing Operation in September, which has so far garnered significant interest from banks. And our preparation for outright purchases in asset-backed security (ABS) markets is fast moving forward and we expect that it should contribute to further credit easing. Indeed, such outright purchases would meaningfully contribute to diversifying the channels for us to generate liquidity.
