When Puerto Rico’s governor, Ricardo Rosselló, steps down on Aug. 2, his successor will be left with a mountain of unfinished business, including the biggest governmental bankruptcy in United States history and an economy propped up by emergency aid.

The island is about three years into a deeply unpopular restructuring of about $129 billion in debt and unfunded pensions, and there is still no clear resolution in sight. Over the years, the territory’s leaders borrowed $74 billion, largely to balance the budget, and exhausted all the money in the public pension system. The island owes retirees about $55 billion.

The bad fiscal habits have yet to be broken.

Since 2016, a federally appointed board has been in charge of resolving the debt crisis, and many Puerto Ricans distrust it, partly because of the cuts to public services it has pushed for. Mr. Rosselló, who took office the same year, has been fighting with the board since then and the two sides had been haggling when Hurricane Maria struck in 2017, causing thousands of deaths and knocking out electrical power across much of the island for months.
