What Were the Chances the South Would Win?

Victory or Repudiation? The Probability of the Southern Confederacy Winning
the Civil War

Marc Weidenmier & Kim Oosterlinck
NBER Working Paper, November 2007

Abstract:
Historians have long wondered whether the Southern Confederacy had a
realistic chance at winning the American Civil War. We provide some
quantitative evidence on this question by introducing a new methodology for
estimating the probability of winning a civil war or revolution based on
decisions in financial markets. Using a unique dataset of Confederate gold
bonds in Amsterdam, we apply this methodology to estimate the probability of
a Southern victory from the summer of 1863 until the end of the war. Our
results suggest that European investors gave the Confederacy approximately a
42 percent chance of victory prior to the battle of Gettysburg/Vicksburg.
News of the severity of the two rebel defeats led to a sell-off in
Confederate bonds. By the end of 1863, the probability of a Southern victory
fell to about 15 percent. Confederate victory prospects generally decreased
for the remainder of the war. The analysis also suggests that McClellan's
possible election as U.S. President on a peace party platform as well as
Confederate military victories in 1864 did little to reverse the market's
assessment that the South would probably lose the Civil War.


This use of financial markets data is far too rare in political science, and history.

At least judging by the abstract, the paper seems to make no distinction between "the probability of a Southern victory" and the European bondholders perception of same.

Given the Atlantic Ocean and mid-eighteenth-century limits on communication and travel, I doubt very much that the Europeans had any particularly good insights, even if their Confederate bond market left good records.

This strikes me as a case of the drunk looking for his car keys under the streetlight rather than in the area he dropped them.

This is a very interesting result, since most sophisticated students of the Civil War mark the fall of Atlanta as the point of no return for nothern victory, since it ensured the defeat of the peace party.
