To me the gold price takes the form of a very uncomplicated formula, and all you have to do is divide one by 'n.' And 'n', I'm glad you ask, 'n' is the world's trust in the institution of paper money and in the capacity of people like Ben Bernanke to manage it. So the smaller 'n', the bigger the price. One divided by a receding number is the definition of a bull market.

The art of banking is always to balance the risk of a run with the reward of a profit. The tantalizing factor in the equation is that riskier borrowers pay higher interest rates. Ultimate safety - a strongbox full of currency - would avail the banker nothing. Maximum risk - a portfolio of loans to prospective bankrupts at usurious interest rates - would invite disaster. A good banker safely and profitably treads the middle ground.

Growth at an exceptional rate is a red flag in banking. It is hard enough to manage an ordinary bank; to control a sprouting weed is well-nigh impossible. If loans are expanding too quickly, the lending officers have probably been saying 'yes' too frequently.

Debt is always repaid, either by the borrower or by the lender.

Successful investing is about having people agree with you ... later.

Every debt is ultimately paid, if not by the debtor, then eventually by the creditor.

Credit is money of the mind.
