It was not unprecedented. Tiberius' two immediate predecessors, Julius Caesar and Octavian had made similarly sized donations to either the people of Rome, the public treasury, or both.

Octavian (Augustus) is at pains to point out that he made similarly massive donations to the public (RG 15) and that he bailed out the public treasury no less than four times, at a number significantly greater than what Tiberius spent (RG 17)

I suppose at some point it depends here on what we understand as a major crisis - evidently significant enough to drag in the emperor...but mostly because its consequences were confined to the landholding elite that dominated Roman politics.

My understanding is that the trigger was the insolvency of a major Alexandrian banking house specializing in shipping, and that it affected cities in Greece and Asia minor and may have even been felt as far north as Belgica, which suggests to me that it was pretty widely spread.

Right - and I am asking where that is in the sources or evidence? Dio, Suetonius and Tacitus do not say this. Barlett provides no additional sources in what I can find of his.

I have to check my books. It is more likely to be in merchant account books than in Roman histories written at the time, which tend to ignore banking and trade in favor of more exciting stuff, like genealogy, aristocratic gossip and military expeditions.

Apart from Puteoli, (D. Jones, The Bankers of Puteoli (2006)), there really aren't many large bodies of merchant account books which survive from this period.

I mean, this is the issue that Peter Temin runs into. He builds out his economic theory, but often struggles to really find the evidence that can support it. His theoretical reconstruction is plausible, but it isn't *necessary* from the evidence.
