By 2021, the global macroeconomic imbalance may return to the historic 2007-2008 levels that preceded the global financial crisis (aka the Great Depression). A high macroeconomic imbalance may be dangerous as the last time it reached these levels resulted in significant global economic downturn.

  • The global macroeconomic imbalance can be measured as the standard deviation of the annual current account balances (CAB) of the largest economies. As goods and services make up the predominant share of the CAB, for simplicity you can consider the CAB balanced if exports equal imports.
  • A positive CAB means a country’s exports exceed its imports, allowing it to accrue savings (earned from exports), and send those earnings abroad in form of investments and financial flows. Germany and Japan were surplus leaders in 2018.
  • A country with a negative CAB, would in contrast need mechanisms to fund its excessive consumption as it absorbs savings from other countries. The United States holds the largest current account deficit, and it’s only expected to grow, climbing from $516 billion in 2018 to a projected $810 in 2023.

Will the current global macroeconomic imbalance prove a harbinger of things to come, a shadow of 2008 cast on the years ahead? This depends largely on how adept deficit countries will be in generating returns on the capital they import. This ability, in turn, depends on their economic growth prospects.

  • The United Kingdom and India, which had the second and the third-largest deficits in 2018, have strong economic growth prospects over the next four years.
  • Growth in the United States and Canada, unfortunately, is expected to only slow.

Export Concentration Index: A Measure of Economic Vulnerability

The concentration index of exports estimates a country’s reliance on a limited group of commodities as its primary source of foreign exchange income. Ranging from 0 (perfect diversification) to 1 (concentrated on a single product)*, a comparison of index scores to the contribution of natural resources to GDP worldwide shows that countries that are resource-rich tend to have less diversified export bases.Last year Iraq’s export concentration index reached 0.97, driven by its export concentration in mineral fuels, namely oil. Other oil exporters—including Angola, Iran, Kuwait, and...

US Imports of Steel and Aluminium: Tariffs Perspective

On March 8, 2018, US president Donald Trump issued two proclamations to adjust US imports of aluminum and steel from all countries except Canada and Mexico, key regional allies and trade partners. President Trump asserted that a 25 percent tariff on steel “articles” and a 10 percent tariff on aluminum articles are necessary for the US to develop its domestic steel and aluminum industries and to protect and create jobs. The US is the world's largest importer of the steel and aluminum articles covered by the proclamations. The import value of steel articles has declined twofold in the...

US-China Trade War: First Signs of Thaw

Weeks after US President Donald Trump and Chinese President Xi Jinping agreed to a temporary halt in the US-China trade war, the first positive signs of a return to normal trade relations are emerging. Last week, the China Grain Reserves Corporation (Sinograin) and fellow state-run Chinese enterprise Cofco bought more than 1.5 million tons of US soybeans, the first significant deal since the countries agreed to a 90-day truce from December 1, 2018, to March 1, 2019. The announcement caused a spike in soybean futures to $918.5 a bushel, the highest price since June.Soybeans were one...

United States: The World's Newest Major Exporter of Crude Oil

In June, US crude oil exports reached historic levels at nearly 2.2 million barrels per day (b/d), a level similar to that of Nigeria and Iran. From 1975 until late 2015, a federal ban on the export of US crude oil severely restricted crude oil exports to all countries except Canada. By lifting the ban, the US Government has transformed the United States into a major exporter of crude oil and a force that is reshaping global oil markets. To date in 2018, the United States has averaged more than 1.7 million b/d of crude oil exports while continuing to import an average of 7.9 million...
