The reason I'm skeptical about this step is because there are simply no specific blueprint whatsoever. And with recent government implementations, their biggest failure turns out to be ambiguity. Good example is GST. After it's launch several month's ago, almost every big/small industry is finding it hard to get the specific details.
I highly doubt about government's ability to implement it. This insurance should have been given on basis of economical standing. Choosing a random 500M number is good for making headlines but again it is not clear on who will gain this insurance benefits?, what will be covered?, how to claim it? I foresee, "divide and rule" :p
On another note, please have a look at Sensex. It's near all time high. The reason behind such rally is not FII but DII. Infact, FII has actively removed over $20Bn since 2015. There was slight influx of FII money post two months of demonetisation but again outflow increased in following months. But still Sensex didn't crashed because of the counter balance from DII or read it as mostly mutual fund companies. Also, I had noticed an increased expenditure in mutual fund investment ads on TV and almost all types of media. And these ads were sponsored mostly by govt bodies and associations. There is nothing wrong to invest in mutual funds. But when I heard about long term and short term capital gains tax today, things got much clearer for me as to why DII raised some much cash in very short period of time. To check the validity of above numbers, you can refer to sensex related stats on moneycontrol.com and check out the YoY sensex FII/DII activity. It has a very well explanatory chart about it.
