This is one of the most common misunderstandings in Islamic finance, and the answer is short: no. Riba is an increase paid on money advanced in exchange for time, and whether that increase is calculated at a rate that stays the same or one that moves with a benchmark does not touch the definition. A fixed rate is more predictable, which genuinely helps you plan - but predictability is a budgeting advantage, not a Shariah one. The confusion usually comes from a real principle applied to the wrong thing: Islamic law does require that a price be known and fixed at contracting, and a floating rate means you cannot state what you will ultimately pay. That is a second, separate objection to floating-rate borrowing. It does not make fixed-rate borrowing permissible; it makes floating-rate borrowing objectionable on two counts rather than one.

Because the prohibition is on the increase itself, not on how it is calculated. Borrowing 100,000 and repaying 112,000 means you paid 12,000 for the use of money for a year - whether the 12% was fixed or averaged out that way from a floating rate. The Quranic prohibition is unqualified as to amount or method, and no scholarly position holds that a fixed rate cures interest.
It is right, but it applies to a sale, not a loan. A murabaha is valid because goods are transferred at a total stated upfront that can never change. That fixity requirement is about sale prices - it is not a rule for how to structure interest. Applied to a loan, no rate structure helps, because the problem is that money was advanced and more money is owed.
It carries an additional objection, yes. With a floating rate you cannot state what you will ultimately repay, which is genuine uncertainty about the size of an obligation - gharar on top of the riba. So fixed borrowing is objectionable on one ground and floating on two. Noting that one is worse does not make the other acceptable.
A sale, not a loan with a fixed rate
The institution buys the asset, takes ownership and risk, then sells it to you at a total fixed at contracting. The distinction from a fixed-rate loan is that goods were transferred and the seller bore ownership risk, not that the percentage stays constant.
Verify the institution actually acquires the asset rather than disbursing cash against your invoice.
