The Latte Index: Using the Impartial Bean to Value Currencies

The Impartial Bean

Using the price of a coffee to estimate currency value

The Chart of the Week is a weekly Visual Capitalist feature on Fridays.

Like any other market, there are many opinions on what a currency ought to be worth relative to others.

With certain currencies, that spectrum of opinions is fairly narrow. As an example, for the world’s most traded currency – the U.S. dollar – the majority of opinions currently fall in a range from the dollar being 2% to 11% overvalued, according to organizations such as the Council of Foreign Relations, the Bank of International Settlements, the OECD, and the IMF.

For other currencies, the spectrum is much wider. The Swiss franc, which some have called the world’s most perplexing currency, has estimates from those same groups ranging from about 13% undervalued to 21% overvalued.

Such a variance in estimates makes it hard to come up with any conclusive consensus – so in today’s chart, we refer to a more caffeinated and fun measure that also approximates the relative value of currencies.

The Impartial Bean

The “Latte Index”, developed by The Wall Street Journal, uses purchasing-power parity (PPP) – comparing the cost of the same good in different countries – to estimate which currencies are overvalued and undervalued.

In this case, the WSJ tracked down the price of a tall Starbucks latte in dozens of cities around the world. These prices are then converted to U.S. dollars and compared to the benchmark price, which is a tall Starbucks latte in New York City (US$3.45).

The Latte Index

The Latte Index is mostly for fun, but it’s also broadly in line with predictions made by the experts.

For example, the price of a latte in Toronto, Canada works out to US$2.94, which is about 14.8% under the benchmark NYC price. This suggests that relative to the USD, the Canadian dollar is undervalued. Interestingly, estimates from the aforementioned sources (BIS, OECD, CFR, IMF) have the Canadian dollar at being up to 10% undervalued – which puts the Latte Index not too far off.

Given the wild range of estimates that exist for currency values, using the relative cost of a cup of joe might be as good of a proxy as any.

An Investor’s Guide to Copper

Copper is the world’s third-most utilized industrial metal and the linchpin of many clean energy technologies. It forms the vital connections in our electricity networks, grid storage systems, and electric vehicles.

In this graphic, sponsored by iShares, we dig into the forces that are set to shape the future of the copper landscape.

How Much Copper Do We Need?

Copper is poised to experience a remarkable 54% surge in demand from 2022 to 2050.

Here’s a breakdown of the expected demand for copper across clean energy technologies.

Technology2022 (kt)2050P (kt)
Electricity networks43648862
Other low emissions power generation93.7142.2
Solar PV756.81879.8
Grid battery storage24.6665.2
Wind453.5 1303.3
Hydrogen technologies-0.22
Electric vehicles370 3582.9
Other uses19766 22382

Copper is vital in renewable energy systems such as wind turbines, solar panels, and electric vehicle batteries because of its high electrical conductivity and durability.

It ensures the effective transmission of electricity and heat, enhancing the overall performance and sustainability of these technologies.

The rising demand for copper in the clean energy sector underscores its critical role in the transition to a greener and more sustainable future.

When Will Copper Demand Exceed Supply?

The burgeoning demand for copper has set the stage for looming supply challenges with a 22% gap predicted by 2031.

Given this metal’s pivotal role in clean energy and technological advancements, innovative mining and processing technologies could hold the key to boosting copper production and meeting the needs of a net-zero future.

Investing in Copper for a Prosperous Future

Investors looking for copper exposure may want to consider an ETF that tracks an index that offers access to companies focused on the exploration and mining of copper.
