Cuba enacted rationing for basic goods in 1991 following the collapse of the Soviet Union, which had previously subsidised the island nation's economy. Rationing started being phased out in the year 2000 at the end of the "special period", as Cuba had shifted to a more diversified and self-sustaining economy. Rationing, however, was not fully abolished and instead turned into an alternative way to purchase goods, in addition to the markets. This makes a curious departure from classical rationing, as during the 2001-2019 period, the rationing system was used in addition to, instead of as a replacement for regular markets. Cubans would be able to buy a certain amount of items at 'liberated' prices using ration coupons at a significantly reduced rate, while still being able to purchase more at regular market prices. This 'liberated' system persisted even during Cuba's period of economic growth and relative prosperity during the early and mid 2010s and enjoyed considerable popularity among the island's citizens. Cuba later re-introduced a classical limiting rationing system in 2019, following the imposition of strict sanctions on the island by US President Donald Trump, as well as the collapse of oil shipments from Venezuela, which was facing its own economic troubles at that time. Cuba's president pitched the new system as significantly more lenient than the 1991-2000 "special period", though admitted that it would negatively affect consumption.
