Let’s assume I buy shares through my bank’s online interface. The bank executes these purchases behind the scenes. Then, the bank shows me that the purchase has been executed and that I own X number of shares.
But where is this information about share ownership actually located?
Let’s imagine for a moment that the bank acts fraudulently and shows me an incorrect number of shares on its website (or that they have intentionally or due to a system error stored an incorrect number in their own databases). What, then, is the actual source for this information about my holdings? How can I verify the bank’s “claim” about my holdings and obtain some kind of written proof of my ownership from this real source?
Which parties receive, or could receive, information about my holdings? How do they get it? From the bank, or from the actual source?
