If they had kept all members whole and only changed the rates going forward then I think we can’t fault them at all.
There’s a risk with all points program devalautions which is why Amex members have valued the ability to warehouse points there. Amex have built up a good repuation over a long period of time.
Providing plenty of notice is nice but my view of Amex has gone down a notch because of the devaluation of existing balances. The hard earned trust has been eroded.
I’m not rushing to cancel my cards though. They are still competative. The change in rates is not surprising given the caps and what has happened in the credit card market.
This is exactly the point. I believe most of us understand market changes and the necessity to adjust to the current situation. But it does not justify what Amex is doing now: halving the existing long-term savings. It is a steal.
