There will certainly be demand for loans, but the supply and demand curves for loans may not intersect anymore, meaning that no loans are made (because given a deflation rate of 5%, a nominal interest rate of, say, 1.5% (only a very small premium over the minimum risk-free rate of 0.00%) is still a real interest rate of 6.5%, which may be more than many of the loan customers are willing to pay.

In other words, deflation makes financing any risky enterprise much harder, so only the mostly highly profitable projects succeed. This makes sense, because in a deflationary environment just holding a pile of cash is a profitable endeavour.
