As the current 3 year swap rate is approx 1.65%, EBS's implied margin is approx 3%. This is similar to their current variable rate implied margin. On that basis I would expect that if they are increasing their variable rates, they will increase their fixed rates also to maintain margin.
Note that implied margin does not take account the overall funding cost, just the cost of interest rate hedging for the bank/bsoc. Other costs would be such as paying 3% for a variable rate deposit when ECB repo rate is 1% - implying a cost of 2.00% for the bank/bsoc on taking the deposit to fund the mortgage.
