Because people will still be earning a pittance on deposit and state savings
You only quoted me saying "
why doesn't he just eliminate DIRT tomorrow and increase the return on State Savings?".
The preceding part of my question outlined that Simon's stated concern is that "
too much of people's hard-earned savings are remaining in low-yield deposits, where inflation can erode value over time".
Eliminating DIRT and raising State Savings returns would both significantly improve the problem he
says he is trying to address, at least for the many people that have deposits in higher interest accounts, be they fixed deposits with the main banks, and on-demand with the likes of Revolut, and fixed with State Savings.
The returns might just about match inflation but would address his stated concern.
Instead, he's addressing his stated concern by encouraging savers to place currently
deposit guaranteed funds into
investment products carrying a degree of risk, and with no guarantee scheme.
I don't know the breakdown of who has most of the current €170bn on deposit at barely above zero rates, but seemingly it's a lot of folks.
If they can't be bothered to treble their interest by shopping around, whilst maintaining a €100k deposit guarantee, why would they move their money into a zero deposit guarantee arrangement? Perhaps if they were fed the story that this is a "Savings scheme" with a great tax let off, rather than being told it's an investment carrying risk. Which is what they are being told at the moment.
I'm not saying there aren't loads of merits to the new scheme, for the right audience, chasing greater returns for their investments. And I know not many on here agree with me.
But I believe that luring the uneducated depositor into this scheme under the guise of it being a savings scheme, when it is not, is dubious. I'm surprised the Central Bank, with it's (not very much used) consumer protection hat on, appears to be jumping on his bandwagon.
