what is DEBT-loan-credit

Debt instruments such as bonds and debentures etc are just a way of accessing the world’s
capital.
It’s like the capital markets provide an easy access to creditworthy institution to access money .
capital market’s simply transfer money from the one’s who have it to the ones who want it and
are willing to pay a price(interest) for it.
Interestingly like I have already said, money is never created nor destroyed it merely changes
shape from one place to other, it automatically finds the best place where it can grow, securely,
with the preference being to security than risk. So if interest rates are low enough making it
unattractive avenue of investment, money will take risks to make itself grow.
