The ISK is better than what we have today, particularly if you want to be invested in low cost, low friction ETF equity funds.
The issue I have as a reference point is that we started with "equivalent of an ISA" and the tax burden does fall materially differently.
This is a pretty effective way to both create a savings product and broaden the tax base. I'll be interested to see how the providers try and rinse us for fees compared to what people are paying in the likes of the UK. Hopefully as part of the strategy rollout the DoF is strong on "this stuff is cheap abroad, it should be cheap here" and encourage really transparent pricing so people can get the best deals, and the challenger brands for pension products push the legacies to do better.
In terms of size the scheme will reach and what success should look like from converting our €170bn of deposits to more productive use: I think this will come down to consumer education. Data from Sweden shows that (perhaps unsurprisingly) the rate of population holding an ISK rises with educational attainment alongside income.
In 2023 about 36% of the Swedish population held an ISK and the median value was about €7.1k in today's euros. Mean is €40.1k. I'm sure the tax treatment changes are impacting that lately.
Just by way of comparison, about 42% of the UK population holds an ISA but the median account value is a lot higher - closer to €38k. Mean is €69.6k. You'd expect that perhaps with the annual limits and such.
So if Irish-ISK take up followed these patterns, you might expect to see about 2m to 2.3m people eventually hold an account, and a total value (Swedish mean and take up rate) of €80bn under management. Just for comparison to ISA (UK mean and take up rate) would come to €160bn, certainly an unrealistic sum.
You could credibly say that the Swedish take up rate, if the scheme is truly designed to follow the ISK, should be the target for success, and be about half the money sitting on deposit going to more productive use. Not to mention generating significant tax revenue every year, albeit with offsets from the TFA, DIRT etc.
