Agree 100%.
Let us also not forget to look at the Bond rates, EU inflation etc. There is nothing to suggest a risk of interest rates increasing in the next few years, with competition likely to help bring our lending rates closer to the EU average.
In isolation, the obvious answer to the 1-year question is to fix at 2.9% and save 0.6% over the year. Costs (both financial and time) must be considered if you were to move, so they need to be factored in as part of this decision, while 1-year is a relatively short time period so the risk of potential long term disadvantage to the customer is limited, if they fix.
If someone moves to the EBS and collects the 2%, is there a "clawback" to consider if they subsequently want to move elsewhere in a couple of years time ? I must say, on a personal level, I would have some concerns about what the future holds for the EBS so would want to be confident that I could leave as easily as I went to them.
