Loans come in ALL shapes and sizes. It all depends on the Lender and the Borrower.
From zero collateral e.g. Fuliza to heavily collateralized e.g. real estate loans/mortgages. Even then there are issues for the latter!
What hard assets would a bank e.g. DTB collateralize when Tuskys probably rents/leases the stores, furniture and buys goods on credit?
The "regulator" - who would that be? - can enact rules based on laws but there are issues with that too. Who should be regulated?
The supermarkets?
Which ones?
Which size?
Who will monitor that?
As they say, do check out who you go into business with!
Perhaps it is time for a group of "suppliers" to start their own supermarket chain. Not easy though!
Greedy when others are fearful. Very fearful when others are greedy - to paraphrase Warren Buffett
