Read a report the other day ( can't remember where) but was discussing the impacts of negative rates on growth, the ECB I think it was went negative in 2014 and Japan in 2016 ( or vice versa) and growth has been sluggish at best less than 2% and strangely with all the printing there was little inflation, showing its not anyway a cure, it will be interesting if we all go down this path how governments will justify it to the people and if everyone will fall for it, that's one of the main reasons it makes no sense for the markets to go back to all time highs so soon, slow growth should mean lower prices.
