Just a day after Governor Alejandro Garcia Padilla signed a law that enables him to temporary halt debt payments, dramatically raising the risk of widespread defaults, Puerto Rico securities had the biggest one-day drop in more than eight months.

Today’s plunge is the biggest decline since July 28, 2015, a day after PR indicated that it was set to skip interest and principal payments on some securities for the first time.

As The NY Times reports, Gov. Alejandro García Padilla of Puerto Rico on Wednesday signed a bill that would allow him to declare a state of emergency and give him authority to halt payments on the island’s crushing $72 billion debt.
