The News From Waterloo Reached London Before the Couriers Did

The Battle of Waterloo ended around 9 pm on June 18, 1815. Wellington's dispatch rider left for London immediately but did not arrive until the evening of June 21 — three days later. The official government message confirming Napoleon's defeat reached Lord Liverpool's cabinet at around 11 pm.

Nathan Mayer Rothschild, the London head of the banking family, had a faster network. His couriers traveled via Ostend, crossing the Channel by night, and one reached London on June 19 — roughly 48 hours after the battle and a full day before Wellington's rider. Rothschild had news of the victory before any British minister.

What Rothschild actually did with the information has been disputed ever since. The legend — popularized in the 19th century and repeated as fact — is that he stood on the floor of the Royal Exchange, sold British government bonds (consols) to signal that Britain had lost, triggered a panic sell-off, and then bought everything back at the bottom moments before the true news arrived. The sequence is vivid and has appeared in textbooks.

The historical record, examined by economic historians Niall Ferguson and others, is more mundane: Rothschild did buy consols in the days after Waterloo, and the price did rise as the victory news spread. But there is no contemporary evidence of a dramatic sell-off and repurchase. The legend grew because it made a better story than 'banker used a faster postal route to buy bonds at a good price' — which is still interesting, and still true.
