At today’s meeting the Governing Council of the ECB took the following monetary policy decisions:

The interest rate on the deposit facility will be decreased by 10 basis points to -0.50%. The interest rate on the main refinancing operations and the rate on the marginal lending facility will remain unchanged at their current levels of 0.00% and 0.25% respectively. The Governing Council now expects the key ECB interest rates to remain at their present or lower levels until it has seen the inflation outlook robustly converge to a level sufficiently close to, but below, 2% within its projection horizon, and such convergence has been consistently reflected in underlying inflation dynamics.

Net purchases will be restarted under the Governing Council’s asset purchase programme (APP) at a monthly pace of €20 billion as from 1 November. The Governing Council expects them to run for as long as necessary to reinforce the accommodative impact of its policy rates, and to end shortly before it starts raising the key ECB interest rates.

Reinvestments of the principal payments from maturing securities purchased under the APP will continue, in full, for an extended period of time past the date when the Governing Council starts raising the key ECB interest rates, and in any case for as long as necessary to maintain favourable liquidity conditions and an ample degree of monetary accommodation.

The modalities of the new series of quarterly targeted longer-term refinancing operations (TLTRO III) will be changed to preserve favourable bank lending conditions, ensure the smooth transmission of monetary policy and further support the accommodative stance of monetary policy. For banks whose eligible net lending exceeds a benchmark, the rate applied in TLTRO III operations will be lower, and can be as low as the average interest rate on the deposit facility prevailing over the life of the operation.

In order to support the bank-based transmission of monetary policy, a two-tier system for reserve remuneration will be introduced, in which part of banks’ holdings of excess liquidity will be exempt from the negative deposit facility rate.

This data set-up we can consider as strong market stimulus. It's hard to analyse if the 10b rate cut will be good, but another QE could make inflation higher. This is very strong set-up for markets but for the economy? The mortgages will be even cheaper and the asset prices could still raising. Will inflation be higher because of assets or real spending?
