They say the road to hell is paved with good intentions. In 1825, to deal with the “Indian Problem,” the US Congress formed a region known as “Indian Country,” lands West of the Mississippi (today Oklahoma). Their intentions were good.

“The removal of the tribes from the territory which they now inhabit would not only shield them from impending ruin, but promote their welfare and happiness,” President James Monroe told Congress on January 27. He went so far as to say that without a defined Indian country “their degradation and extermination will be inevitable.”

It’s heartening to know that at least some of the President’s contemporaries could see through his good intentions. New York County District Attorney Hugh Maxwell and twelve other prominent New Yorkers wrote in a pamphlet published in1825 that “the American Indians, now living upon lands derived from their ancestors and never alienated or surrendered, have a perfect right to the continued and undisturbed possession of these lands,” and the “removal of any nation of Indians from their country by force would be an instance of gross and cruel oppression.”

History was not on Mr. Maxwell’s side, nor with his attempts to reform the financial industry a few years later. His prosecution of the Life & Fire Insurance Company, whose owners Jacob Barker, et al perpetuated a fraud that led to the Panic of 1826, resulted in a hung jury. (Eventually, Mr. Maxwell’s efforts did lead to comprehensive reform, including: financial reporting requirements, accounting standards, and defined roles & responsibilities for directors, according to Professor Eric Hilt in a paper about the Panic of 1826.)

Mr. Maxwell’s rationality was no match for his era’s good intentions. For what lead Life & Fire’s directors to commit fraud in the first place was in part driven by a desire (so they claimed) to extend credit to high-risk borrowers being ignored by traditional banks. When those borrowers started to default en masse, fraud appeared to be the only way to repay their investors, but unfortunately, even that didn’t work.

Why was an insurance company doing a bank’s work? In the 19th century, banking was the most profitably industry in America, and incumbent banks fought hard to protect their profits. To open a new one involved special-act charters and bitter legislative battles. Would-be owners required both political and financial capital, which few had in equal measure.

Enterprising merchants like Mr. Barker started circumventing these laws by forming insurance companies whose charter empowered them to lend their capital. In so doing, they created a new financial product called a post note. A typical post note transaction went as follows: a borrower approached an insurance company and requested a six-month IOU of $1000, minus a discount of say 3%. The borrower would then sell the discounted $970 post note on the money market, also paying a discount to the post note purchaser of say $30, receiving $940 in cash.

After six months, the borrower would repay the insurance company’s IOU of $1000. The insurance company would repay the money market investor’s post note of $970, yielding a $30 profit for both the insurance company and the investor.

While rates and terms varied, it was not unusual for post notes to trade at yields of 2 percent per month or more, compared to banks that were lending at yields of five percent per year, Professor Hilt’s research found. Needless to say, these products were very profitable as long as default rates were low.

But higher yield meant higher risk, since borrowers who sought out post notes did so because they did not qualify for the less expensive credit from traditional banks. Despite their dubious quality, the corporate guaranty by the insurance company created a ...
