I prefer not to get too wonkish here, but this ruling could put a kink in US-based finance's history:
In so doing, the court most likely damaged the status of New York as the world’s financial capital. It made it far less likely that genuinely troubled countries will be able to restructure their debts. And it increased the power of investors — often but not solely hedge funds that buy distressed bonds at deep discounts to face value — to prevent needed restructurings.
