# What the US blockade of Cuba is

> The US blockade of Cuba is a set of US laws and rules that limit trade, travel and money between the two countries. It began in the early 1960s and is run today by the US Treasury [1]. Cuba calls it a blockade, the UN resolution calls it an embargo, and the US government says there is no blockade [2].

## Two words for one policy

Cuba's government and many of its supporters say "[blockade](https://cuba.timothybrits.co.za/glossary#blockade)." The US government says "[embargo](https://cuba.timothybrits.co.za/glossary#embargo)," or just "sanctions."

The UN resolution uses "embargo." Its full title is "Necessity of ending the economic, commercial and financial embargo imposed by the United States of America against Cuba." [3]

In the law of war, a naval blockade means a country at war stops ships from all states reaching certain ports. Two legal scholars wrote in April 2026 that "embargo" fits the US measures better. They say there is no armed conflict, and the measures come from US domestic law. [4]

In the UN debate in October 2026, Mr Waltz, the US ambassador, said: "There is no blockade." [2]

This site uses both words. "Blockade" appears in its titles because Cuba and many of its supporters use it. In both cases the subject is the same set of US rules.

## How it began

On 3 February 1962, US President John F. Kennedy proclaimed an embargo on trade between the United States and Cuba. [5] Imports of Cuban goods were banned from 7 February 1962. [5]

UN News says the embargo was first imposed in 1960. [2]

In July 1963, the US Treasury issued the Cuban Assets Control Regulations. They ban most trade and money transfers and freeze Cuban government assets. [6]

## What the rules do today

A Treasury office called [OFAC](https://cuba.timothybrits.co.za/glossary#ofac) runs the rules. It says the Cuba sanctions come from "multiple legal authorities." [1]

In 1996, the [Helms-Burton Act](https://cuba.timothybrits.co.za/glossary#helms-burton-act) wrote the embargo into US law, as it stood on 1 March 1996. [7] A Congressional Research Service report says the President cannot end the embargo alone. [6]

The rules ban most dealings with Cuba for people and companies in the US, unless OFAC allows them by licence. [1] US law bans tourist travel. [6] Sales of food and medicine are allowed, but only under licence and for cash in advance. [6]

The rules grew tighter in 2026. New rules that took effect on 30 September 2026 ended a general permission for group "people-to-people" travel and a rule that let some payments pass through US banks. [8]

US banks must now block accounts held by Cuban private business owners. [9]

Travel is still limited. Only 12 listed kinds of travel are allowed, and tourist travel to Cuba stays barred. [9]

The State Department keeps a list of Cuban firms called the Cuba Restricted List. Since 30 September 2026, US persons may not make even indirect money transfers to firms on it. [9]

Some activities are still allowed under general licences. The new rules name legal services, emergency medical services and humanitarian work by non-profit groups. [8]

The new rules also let the US sanction banks outside the US that handle "significant" transactions for blocked people. [8] That reach beyond US borders is called [extraterritorial](https://cuba.timothybrits.co.za/glossary#extraterritorial-sanctions).

## Why people disagree

Cuba's foreign minister told the UN in July 2026 that the measures cost Cuba about $8 billion between March 2025 and February 2026. [10] This is Cuba's own estimate. We have not seen it checked by an independent source.

Cuban authorities say the embargo harms the country's health system, including delays to vaccination programmes. [2]

The US government disagrees and says Cuba's problems come from its own government. [2]

On 28 October 2026, 130 UN member states voted to call for the embargo to end. Seventeen voted against and 25 abstained. [11]

South Africa supports ending it. In August 2026, Parliament's committee on international relations "reaffirmed South Africa's long-standing support for the immediate and unconditional lifting" of the embargo. [12]

## Main counterarguments

- The US government says there is no blockade. Its ambassador to the UN, Mike Waltz, told the General Assembly in October 2026 that US exports to Cuba were more than $876 million in the first eight months of 2026 [2]. US law also allows sales of food and medicine to Cuba, but only under licence and for cash in advance [6].
- The US government says Cuba's hardship comes from its own government, not from US rules. In July 2026 the US representative at the UN blamed the Cuban government for repression and for the country's economic problems [10]. Mr Waltz said Cuba's wealth had passed from ordinary Cubans to a ruling elite [2].
