The following chart gives a
snapshot of the top 20 countries, ranked by their index of power in the world
economy. Readers of this blog or my book, The City, will have seen
this concept before,[1]
but here the information is updated to 2016-17.
Index of Power, 2016-17
Notes: The height of each
bar is given by the country’s total index value, which is then broken down into
the respective components. Countries are identified by their two-letter ISO
code. Take care, because CH is Switzerland, not China (which is CN), and DE is
Germany.
The overall picture shows a
small number of countries, led by the US, towering over the rest. Only 33
countries out of 180 have an index that is more than 1% of the US index number!
In a chart, most of the columns would look like the x-axis, so here I have shown
just the top 20 countries. Of those, only five are close to or above 20% of the
US number: the UK, China, Japan, France and Germany.
The UK remains number 2 on these
updated figures. But its index value has slipped back in the past few years on
most measures, and likely will slip further in future with the impact of
Brexit. China stays number 3, but has come in closer, helped by its GDP growth,
a greater use of its currency in world markets and by the size of its foreign
direct investment assets (FDI).[2]
France has edged a little above Germany in the latest ranking, helped by the
better relative position of banks in France.
I have excluded from the chart
several countries whose ranking is boosted artificially, namely in ways that do
not reflect its power. For example, in the latest data the Cayman Islands stood
out as an international banking centre and a home of foreign direct investment.
But the banks and the assets have little to do with citizens of the Caymans.
Ireland and the British Virgin Islands are excluded for similar reasons
relating to FDI.
Statistical details
Roughly 180 countries have been
taken into account for this ranking. Depending on the statistical measure used,
data are available only for 40 to 150 or so.
My five measures are:
- Nominal GDP (2017 estimates,
IMF)
- Foreign Direct Investment
stock outstanding (at end-2016, UNCTAD)
- Outstanding cross-border
lending and borrowing by banks (September 2017, BIS)
- The use of a country’s
currency in international markets (April 2016, BIS)
- A country’s military
expenditure (2016, SIPRI)
If a country is top in all
categories, eg it has the biggest GDP, the biggest military spending, and so
forth, then it would have an index number of 100.0. If another country had a
GDP half the size of the biggest one, then its number on this measure would be
50; if its FDI were only one-quarter of the biggest country (not necessarily
the same country), then its number would be 25; if it had the biggest
international bank lending and borrowing, then its number would be 100. Taking
each of its five individual measures and dividing by 5 would give the final
index number for that country’s power rank. The measures have equal weights.
So what?
The idea behind this chart is to
present key features of the world economy in a summary way. At the very least,
it gives the lie to the absurd notion that there is an ‘international
community’ and instead makes one focus on global power relationships. Each of
the measures has limitations, discussed elsewhere, as is true for any set of
data. But the evolution of the chart is also useful for tracking how the
relative strengths of the major powers change over time.

[2] Data for
Hong Kong and China should be combined, since they are one country. However,
there are difficulties. For example, this can easily be done for GDP, but in
the case of FDI, most of Hong Kong’s is in China. So I have included only
China’s FDI (most of which I believe is outside Hong Kong). In the China data
shown, I have added Hong Kong only for GDP and FX. Banking is taken as the
average of the two; FDI and military spending is China only. The resulting
index number will probably slightly understate China’s importance.
