The Comptroller's Eye

What Hugh McCulloch invented in 1863 · 17 pages

The First Signal

On December 15, 1863, a twenty-seven-year-old postmaster named Edward Green walked into the First National Bank of Malden, Massachusetts, and shot seventeen-year-old Frank Converse in the head. Converse was the son of the bank's president. He died immediately. Green took five thousand dollars and fled. He was captured within weeks, convicted of murder, and hanged.

The bank operated under a system that had existed for less than six months. Its supervision fell to a new federal office—the Office of the Comptroller of the Currency—created in June 1863 with Hugh McCulloch as its first Comptroller. When the OCC examiner arrived in Malden in the months that followed, he encountered something the official instructions had not anticipated: a bank that had been physically attacked. The instructions told examiners how to assess loans, verify capital, and judge the character of management. They said nothing about what to do when a teller had been murdered and cash had been taken at gunpoint.

The examiner reported it anyway.

And as similar incidents accumulated—not just Malden, but a dozen more robberies across the Midwest and border states over the next decade—the guidance changed. OCC annual reports began to mention vaults, safes, night watchmen, and procedures for safeguarding assets. Attention to operational security rose through the late 1860s, peaked in the early 1870s, and then, slowly, faded. By 1882, it was back near where it had started.

This pattern is the central fact of this book. Supervisors respond to crises. They learn from them. They update their guidance. And then, as the memory of the crisis fades, so does the attention they give it. The examiner who wrote the vault-security section of the 1871 examination manual eventually retires, and his successor has other concerns. The guidance that once reflected hard-won knowledge about a specific, demonstrated threat becomes institutional background, then becomes nothing at all.

This chapter shows the first instance of a pattern that will repeat for the next sixteen decades. The robberies of the late 1860s gave rise to vault-security guidance that decayed by the 1880s. The S&L crisis of the 1980s gave rise to interest-rate-risk supervision that, by 2018, had returned to levels last seen in the low-rate 1960s. Three months before Silicon Valley Bank collapsed in March 2023, the Federal Reserve's attention to market interest rate risk was near its historical minimum. The cycle that Edward Green set in motion in December 1863 was still running, in a different domain, one hundred and sixty years later.

Understanding why the cycle runs—what causes supervisory attention to spike and what causes it to decay—is what this book is about. This chapter begins where the cycle itself began: with McCulloch, an empty examination manual, and a robbery in Massachusetts.

Why Supervision Exists

Banking rests on a problem that cannot be solved by the people who face it. When a depositor hands over a dollar, the dollar does not sit in a drawer. It is lent out, pledged as collateral, pooled with other deposits, invested in bonds, or extended as credit to a farmer whose harvest is still six months away. The bank knows what it has done with the money. The depositor does not. And because the depositor cannot see the loans that stand behind his claim, he must trust that those loans are sound. That trust, in turn, is the hinge on which the entire banking system swings. When trust holds, a small reserve suffices; when trust breaks, no reserve is large enough.

Supervision exists to bridge the gap. An examiner, acting on behalf of depositors who cannot evaluate the bank themselves, visits the institution, opens the loan files, and verifies that what the bank claims to own actually exists and is worth what the bank says it is worth. This is the first and oldest function of bank supervision, and it is what McCulloch's 1863 instructions required examiners to do: to read the loans, loan by loan, and to verify the balance sheet against the underlying paper.

The full chapter continues through three sections: the founding logic of supervision, the cycle of attention and decay across the robbery era, and the first glimpse of the pattern that will recur in every subsequent risk domain. The complete book chapter, the figures, and the supporting data are all available to readers of The Supervisory Compass. Until then, the SPI Explorer lets you see the robbery arc and every other domain's arc directly.
