Inflation is a global problem. At the end of August, it was 8.3% in the US and 9.1% in the Euro area. It is 20.3% in Nigeria, 25% in Malawi, and over 30% in Ethiopia and Ghana.

The impact on Africa is devastating. The International Energy Agency estimates that by the end of the year 30 million more Africans will be unable to afford fuel for cooking. The World Bank estimates the number of Africans living in extreme poverty will increase from 424 million in 2019 to 463 million this year.

There is no agreement on why this is happening. Some argue that it is primarily a supply side problem. The dislocations in supply chains caused by the effects of the COVID pandemic and the war in Ukraine have reduced the available supply of goods like fuel, fertiliser and food, forcing their prices up.

Others maintain that it is primarily a consequence of the loose monetary policies of leading central banks like the US Federal Reserve (Fed). For a number of years they have kept interest rates low and engaged in quantitative easing. This involved buying bonds on financial markets to increase the funds available to financial institutions like commercial banks, investment banks, asset management firms, private equity firms, hedge funds, pension funds, insurance companies, money market funds, and sovereign wealth funds.

These two groups also differ on how to manage the problem. The first group argues that it will diminish as the supply side issues are resolved. They maintain that the current high prices will incentivise companies to increase production. The increased availability of goods like food, fuel and fertiliser, will ultimately lead to their prices - and inflation - falling.

The second camp argues that central banks should raise interest rates and unwind quantitative easing. They argue that these actions will make it more expensive for companies, households and governments to borrow. This in turn will slow the economy down and reduce demand (and potentially employment). This, they maintain, will drag prices lower and end inflation.

Unfortunately, the realities of global financial governance mean that the decision on which approach to adopt has been taken out of African hands.

The Federal Reserve has decided that the problem must be addressed as a monetary problem. Consequently, it is raising interest rates and unwinding quantitative easing.

African central banks must follow suit for at least three reasons.

Why African countries have no choice

First, the US dollar is the world's most important currency. In 2021 it accounted for 59% of global foreign reserves, over 70% of all trade invoices and over 60% of both deposits and loans denominated in non-local currencies. In 2019 it was involved in over 80% of foreign exchange transactions around the world.

The dollar's dominance means that the economic wellbeing of all countries is linked to their ability to obtain dollars and to its price in their local currency. It also gives the Fed, which is responsible for protecting its value, global leverage.

Second, the US$27 trillion market for US treasury securities is the largest and safest in the world. When there is trouble or uncertainty in the world, investors rush to buy dollars and invest in US markets. Their incentive to do so strengthens as the difference between US rates and those in other countries shrinks.

African central banks wishing to manage these movements have to raise their interest rates. Otherwise, they face the prospect of their currencies depreciating as investors sell assets denominated in local currencies to buy dollars. The falling value of their local currency will make it more expensive for their countries to buy the dollars they need to service their dollar denominated debts and pay for imports. This in turn risks causing higher domestic inflation.

Third, de facto, the Fed is the most important actor in the governance of the international financial system.

For example, at the onset of the COVID-19 pandemic panicked investors around the world scrambled to convert their investments into dollars thereby reducing access to credit for sovereigns, corporations, and households around the world. The Fed, to avoid a crisis in US markets, responded forcefully and rapidly. Within weeks, the Fed injected over US$2.3 trillion into financial markets and activated swap lines that provided access to $30-60 billion to select central banks.. It also created a special facility to help other central banks.

The Fed's actions provided liquidity to financial institutions. They, in turn, decided how to allocate the trillions of dollars of additional liquidity among their many sovereign, corporate and household clients.

By mid-2020 US dollar credit to emerging market and developing countries had grown by about 7% to US$4 trillion.

The IMF, ostensibly the leading global economic governance institution, moved more slowly. Between March 2020 and March 2022, it provided a total of US$171 billion in emergency financial support to 90 countries.

The Fed's role today

Now that the Fed has decided to fight inflation, it is, in effect, reversing the support it was giving to the global economy. Its policies are contributing to depreciating currencies, rising prices and greater risk of debt defaults in many African countries.

International organisation can do relatively little to help developing countries deal with the situation. At best these institutions can make tens of billions of dollars available to all their developing country member states. By comparison, the US Fed's quantitative tightening policy will withdraw US$95 billion per month from markets.

The growing role of the Fed in global financial governance poses two challenges. The first is that the Fed is a creature of US law and is required to fulfil its statutory mandate of price stability and full employment in the US. To the extent that it takes the impact of its actions on other countries into account, it focuses on those countries that it believes have a significant impact on the US domestic monetary and financial situation.

This exacerbates the international financial system's bias in favour of the richest countries. It may also adversely affect the sustainability of the global economy and the planet.

The second challenge is that African countries have no means for holding the Fed accountable for the adverse impacts its actions have on Africa.

What can African states do?

Clearly, their options are limited as long as the dollar retains its dominant position in the global financial system and global financial markets remain so powerful.

First, they can promote greater awareness of the impact this situation has on Africa.

African central banks, operating through an organisation like the Association of African Central Banks, can educate the Fed about the impacts of its policies and actions on Africa.

Second, they can advocate for an international body such as the Bank for International Settlements, to set up an independent office to study the global financial governance role of central banks, to consult with affected parties and to issue regular public reports. This office should develop a set of international standards to guide the Fed and other leading central banks on how to balance their domestic mandates and their extra-territorial responsibilities as global financial governance actors.
