Former Vice President Dr. Mahamudu Bawumia has cautioned against the use of tariffs as a remedy for trade imbalances, stressing that such deficits are macroeconomic in nature and not the result of trade policy failures.
Speaking at the International Democracy Union (IDU) Forum in Brussels on Saturday, May 17, Dr. Bawumia was responding to a question on how the weaponisation of trade is affecting African economies, particularly Ghana, and what strategies could enhance the continent’s economic resilience.
“Policymakers are increasingly ignoring both economic fundamentals and the lessons of history,” he said.
“If you look at the share of global trade, Africa contributes just 2.5% of global exports and 2.9% of imports, while Asia, Europe, and the U.S. dominate global trade flows with significant imbalances.”
Dr. Bawumia argued that despite these imbalances, imposing tariffs does not address the root cause of trade deficits.
“You cannot fix a trade deficit with tariffs — it simply doesn’t work,” he emphasised.
Explaining further, he referenced the national income identity, noting that a trade deficit reflects a gap between a nation’s savings and investment.
“If a country spends more than it saves, it will run a trade deficit. That’s a macroeconomic problem, not a trade policy problem,” he said.
He cited historical examples, such as the 1930s Smoot-Hawley Tariff Act in the U.S., which contributed to the Great Depression, and the U.S.-China tariff war in 2018–2019, which negatively impacted global trade.
“The recent increase in average U.S. tariff rates from 2.4% to 10% is the largest since 1943, and its effects will be significant,” he warned.
Turning attention to Africa, Dr. Bawumia acknowledged that the continent is somewhat insulated from U.S. trade shocks, with Africa exporting 6.5% and importing 4.4% of goods to and from the U.S.
However, he highlighted countries like Lesotho, whose textile exports to the U.S. account for 50% of their total exports under the African Growth and Opportunity Act (AGOA), as being vulnerable.
Dr. Bawumia predicted that Africa’s response to global trade disruptions would include a renewed push for self-reliance and stronger intra-African trade ties.
