Just one example: Foreign banks must report all financial activities of Americans to the US. An American official wad asked in an interview if the US would then report financial activities of non-Americans to their home tax authorities. The answer was "lol, no, that would be too much effort".
I am having a moment of Schadenfreude...
The U.S. predominantly compels banks through FATCA. If a bank wants to do business in America, it has to follow FATCA for Americans abroad. There is, of course, some regulatory co-operation. But to my knowledge, most countries don't directly transmit these data to the U.S.–the banks have to report it instead.
The correct analogy would be a foreign country requiring U.S. banks to send them data on their own citizens abroad. Which, I think, e.g. India could probably do.
India does get information from the US and other countries about Indian residents having accounts (bank, brokerage, etc.) in other countries.
There are agreements across several countries that use CRS (Common Reporting Standard) to report such information to other countries for tax purposes. This is not India or US specific.
I know for a fact that the US reports financial information about non-US residents to their home countries.
People get into trouble with Indian tax authorities all the time because they neglected reporting their US income and/or holdings.
"Forced"?
You're _way_ everestimating US influence.
Most countries not just "collect citizenship data", they require you to have a valid non-expired ID, valid non-expired residential registration, a fresh digital photo, verified phone number and a valid tax number. All of that without any US interference.
After I told that bank I'd moved abroad, they required me to fill out paperwork for FATCA and give them my US SSN.
I also have to self-report all foreign accounts and their balances to the IRS. The penalties for not doing so are severe.
Since that time, we have grabbed on tighter and tighter, and are finding that the world is starting to seek out a less politically volatile patron for a financial system.
