Mortgage tracks - Be careful!

I have a difficult question for 'mortgage consultants'.

Between 2007 to February 2022, the Bank of Israel interest rate started to decline until it reached around 0.1 – 0.25%. Then, in February 2022, it began to significantly increase, and currently stands at 4.5%. In January 2020, there was already talk of monetary expansions, and send funds to the US and international economies.

To me, it was very clear that we were heading towards inflationary acceleration, which would lead to an increase in interest rates. So why on EARTH do 'mortgage consultants' still recommend a 'varied portfolio' which includes an index-linked track, where the debt is tied to the increases in the index and inflation?

One could argue that a prime-linked portfolio could be repaid without any penalties, so perhaps there is some logic in it, even though I believe that a portfolio with a fixed interest rate is the optimal solution.

My answer - I believe that many 'mortgage consultants' want to create an impression that they are offering a good deal to customers with low interest rates and a diversified portfolio, while in reality, they are screwing the customers over by introducing them into an index-linked track so that the portfolio will be profitable for the bank which could then provide "good interest rates" to customers.

If someone has a better explanation, I would be happy to hear it.
