Did Mansa Musa's gold really crash Cairo's economy?

Partly. The pilgrimage of 1324 and the large gifts of gold are well supported, and gold appears to have lost value against silver in Cairo afterward. The popular claims that the price stayed low for about twelve years, or that Egypt's economy was wrecked, are not supported by the wider evidence. The historian Warren C. Schultz argues that the episode was one of several short-term disruptions to exchange rates. [1] [2]

The story comes from Shihab al-Umari, a 14th-century chronicler who lived in Cairo after the visit and heard residents recount it. In the translation by Hopkins, he wrote that Musa flooded Cairo with his benefactions and that Cairenes exchanged gold until its price fell. Before the visit, he said, the gold mithqal did not go below 25 silver dirhams; afterward it did not exceed 22. He added that this had been the state of affairs for about twelve years. [3] [1]

Al-Umari did not see the caravan himself, since he was in Syria in 1324, so his account is secondhand. He also wrote that Cairenes made incalculable profits from Musa and his entourage, which does not describe a ruined economy. The BBC's figure of ten years is not attributed to any chronicle. [1] [3]

Schultz, a historian of Mamluk money, points out that three later writers, Ibn Kathir, al-Maqrizi and Ibn Hajar, also record a fall in gold's value, though they disagree on its size: two dirhams, six dirhams, and no figure respectively. None supports the twelve years. His table of recorded rates for roughly 1299 to 1349 shows 20 dirhams per gold coin as the most common figure, and a citation from the year after the pilgrimage records a return to that rate. He calls the dip one of many short-term fluctuations. These later writers are known here only as reported by Schultz, and a table built from scattered chronicle mentions is indicative rather than conclusive. [1]

Schultz also names other supply shocks: a rapid sell-off of ornamental wealth by Mamluk amirs said to have occurred in 725 (Islamic calendar), and a large amount of gold taken from the sacking of a high-ranking amir's palace in 742. He adds that medieval money supply was not easily controlled, since it consisted of coined and uncoined gold and silver, with coins of differing origin, purity and age circulating at varying rates. [2]

Schultz himself notes that al-Umari was a mature adult living in Cairo shortly after the events, which bears on his reliability, and he accepts that Musa's gold lowered the gold-silver rate in 1324. He speculates, and says so, that the twelve-year line may have been a veiled criticism of the sultan al-Nasir Muhammad. The longer version has nonetheless entered teaching: of the world history textbooks Schultz surveyed, 12 mention economic disruption and 8 of those describe it as long-term. [1]

The hajj, the gold gifts and a fall in gold against silver are established. A twelve-year slump or a collapse of Egypt's economy is not documented, and the modern dollar valuation of Musa's wealth traces back only to a 2012 website list. One popular summary notes that the details concern Egyptian commerce, not a demonstrated collapse of the world gold market. [1] [4]
