MEXICO CITY — Burned-out cars, makeshift barricades and shuttered businesses signaled a week of unrest in Haiti, where protesters are demanding the resignation of President Jovenel Moïse and more violent protests are feared.

Streets, schools and banks were closed throughout the country, bringing the economy to a standstill. Shortages of oil, power and food abound. The nation’s currency is in free fall, and allegations of corruption linked to Mr. Moïse have brought the nation to a crisis point.

“To me it is obvious: The president, particularly, doesn’t govern anything at all right now,” said Fritz Jean, a former prime minister and past governor of Haiti’s Central Bank. “In fact, we are in a state of vacancy right now.”
