Ally Yo-Yoing Their CD Rates?

 
So what's with this flip flopping of CD rates the past
couple of month's by Ally?  No big deal, but it seems an
awkward strategy just to allow them to assert a "raise
in rates".

For example,
on 5-8-12 the 5 year CD APY changed to 1.69%, then
on 6-15     "   "   "     "    "       "         "   1.65%, then today
on 6-21     "   "   "     "    "       " back  "   1.69%.

In the similar time frame their
3 month CD APY went 0.39% -> 0.34% -> 0.39% and their
9     "     "     "     "      0.74% -> 0.64% -> 0.74%  "    "
11   "     "     "     "      0.94% -> 0.91% -> 0.94%.

I dunno --- perhaps I'm brainwashed by the steady APY
decreases of the past few years that I'm now overly
suspicious when I see any increases!

Although I'd like to give Ally the benefit of the doubt on
these flip-flops this also reeks of a (very poor) marketing
strategy to create artificial rate hikes.  Kind of an insult
to customers.
