There can be few fields of human endeavor in which history counts for
so little as in the world of finance. Past experience, to the extent
that it is part of memory at all, is dismissed as the primitive refuge
of those who do not have the insight to appreciate the incredible
wonders of the present. Only after the speculative collapse does the
truth emerge.
—John Kenneth Galbraith, A Short History of Financial
Euphoria, 1990
All the recent talk about government Bitcoin reserves has gotten me thinking about what happens when governments speculate.
By the time governments decide to take the plunge to make money by speculating, whatever craze they are joining is likely nearing an important and very bad turning point that will lead to regret. This is because in their actions governments are by nature conservative in the ordinary sense of the word and tend to follow rather than lead investment trends after long delays. (Sometimes, as you will see below, the opposite happens: Governments sell assets at the bottom believing low prices signal that such assets are no longer useful or relevant. They thereby miss out on the next bull market proving that their timing is backwards at both market extremes.)
Government employees' conservatism in action comes from being constrained by a web of rules that tell them what to do and when to do it. This is no more the case than in the management of government treasuries. That money is there to be spent on things the elected representatives decide to spend it on. In the meantime, it should be invested in low-risk securities with a very low likelihood of default, and that usually means investing in government securities of short duration. That also means low returns. But accepting such returns is said to be justified by the desire to make sure no money is lost.
