There is expectation that ECB will take further measures in December to create inflation in eurozone. Outlook for interest rates in Europe is for further decrease.
The best short term rate is Rabo 90 day deposit. I can see this dropping significantly in the new year.
I would guess that Rabo will cut their instant access and notice rates by another 0.25% in the coming months. Rabo lately seem to review these rates every 6 months or so and normally move in increments of 0.25%.
I think the KBC 1.40% AER fixed rate is worth grabbing while our lasts.
