@roboquant: The 2011 debt ceiling crisis brought the world's largest economy to the edge of default. Congress deadlocked for weeks. The S&P 500 fell 17%. The VIX hit 45. Then S&P did the unthinkable — downgraded the US from AAA to AA+. First time since 1917. US Treasuries paradoxically rallied. There was nowhere else to flee. The deal was signed 2 hours before the deadline. Political risk is market risk. The clue was always there. Which slide hit you the hardest? #debtceiling #usdebt #spdowngrade #marketcrash
