Sudden stops are when capital inflows dry up abruptly. The banker’s aphorism—'It’s not speed that kills but the sudden stop'— has been popularly invoked since at least the Mexican crisis in 1994. Awareness then rose with impetus from the Argentine crisis (1995) the Asian crisis (1997) the Russian crisis (1998) and the Brazilian crisis (1999). Google’s Ngram Viewer shows a sharp increase after 2000 in references to the phrase.
