But there are a lot of variables. For example, it is possible to change the length of that loan. If the term changes from, say, five years to 20 years, there is far more time for the company to go bust, for interest rates to change and for inflation to rise. And how much interest should bond holders receive? Are they paid enough to make it worth their while moving out of cash? Will their payments rise with inflation?
