Interestingly, since the failure of OFX, many many banks in North America prefer screen scraping because they can guarantee the web interface has accurate data since their actual customers use it. Conversely, these banks find supporting APIs to be highly fragile since no one is watching them.

I find that logic amazing, but considering how old the online banking software is and the high risk of changing it wholesale, I don't think they are in a position to fix it in the short term.
