Sure. If your idea of saving is losing money.
Its not "losing money" though, its a degradation of spending power in relative terms.
People so often grossly simplify things like this to get bullet points for headlines and then they get misquoted and misrepresented of the facts, then it becomes "general knowledge" that if inflation is greater than interest rate your losing money.
E.g Basically housing prices are static, if your saving at 3% interest to purchase a house then your ARE gaining on the relative spending power of your money each year.
If your saving money to spend on stuff like electricity, petrol, food then yes you are potentially losing spending power as your 3% may be exceeded by the inflation ON THOSE PRODUCTS.
My understanding of these alternate borrowing/lending schemes is you have to wait till its repaid (or not), you cannot just go in and demand your money back (some may allow you to sell to another lender, I am not sure). Some may pool debts and borrowings maybe? But the ones I have seen you lend to specific borrowers in small amounts to many borrowers spreading your risk, and wait as the cash is repaid. In effect you wait until the very end to get your interest as its only once you have had the whole of the original loan repaid that you can consider you have made any interest.
Something most people do not even do when signing up for their own mortgage.
