How would you go about doing this? As an example, if you loaned someone 167 monero to buy a car and expect them to pay you back in 7 years like a bank does you would be requesting 167xmr*6.02% (to counter xmr inflation) for a total of 177.053xmr. 177.053xmr/84 (months in 7 years) would be 2.107xmr a month. At the moment that is fine, but if the usd price of monero rises and the borrower is being paid in usd then they are going to default and you will loose the xmr. The only way I could see to counteract this would be to lower the Monero payments per month, but then that would take even longer to be repaid.
But if you pay out Monero for the loan and then you peg it to Fiat and they pay you back in Monero with that amount of Fiat, then you will lose Monero as the price increases. So you will turn say 177 Monero into say 100 Monero. That is something you don’t want to do.
Well you don’t want to lose Monero and you don’t want to lose fiat, but you can’t have both. XMR isn’t a stablecoin.
If it matters more to you that you get your XMR back, then require XMR payments. You need to include the XMR volatility as part of the interest rate calculation.
If it matters more that you get your fiat back, then require fiat-equivalent in XMR payments.
Or, demand you get either XMR or fiat back, whichever is higher. But I don’t think a borrower would like this. Tesla did this when they let you pay in BTC; Tesla reserved the right to refund you in whichever currency was cheaper. For the consumer, it a bad deal.
What do you mean you’d be left with more value? If I loan a hundred and seventy-seven Monero and I only get a hundred Monero back, I am down value. I want the loan amount denominated in Monero and I want the loan payments to be repaid in Monero. I don’t want somebody to tell me I need to borrow a hundred thousand dollars. I want somebody to tell me I want to borrow a hundred and seventy seven Monero.
