Greetings, value-conscious reader of where money actually goes furthest!

"Purchasing power" sounds like a single, simple idea. It isn't. A country can rank near the top of the world for wealth per person while ranking only middling for how far that wealth actually stretches day to day — and the countries topping each version of this measure aren't always who you'd expect.

So where is purchasing power genuinely highest?

Let's dive in.

Blu Dot surpasses 2,000% ROAS with self-serve CTV ads

Home furniture brand Blu Dot blew up on CTV with help from Roku Ads Manager. Here’s how:

After a test campaign reached 211,000 households and achieved 1,010% ROAS, the brand went all in to promote its annual sales event. It removed age and income constraints to expand reach and shifted budget to custom audiences and retargeting, where intent was strongest.

The results speak for themselves. As Blu Dot increased their investment by 10x, ROAS jumped to 2,308% and more page-view conversions surpassed 50,000.

“For CTV campaigns, Roku has been a top performer,” said Claire Folkestad, Paid Media Strategist, Blu Dot. “Comping to our other platforms, we have seen really strong ROAS… and highly efficient CPMs, lower than any other CTV partner we've worked with.”

Using Roku Ads Manager, the campaign moved from a pilot to a permanent performance engine for the brand.

The IMF's official purchasing-power-adjusted GDP figures reveal a top tier dominated by tiny, ultra-wealthy nations.

🇱🇮 Liechtenstein leads the world at $195,372 per person, adjusted for purchasing power.

🇸🇬 Singapore follows at $173,708, and 🇮🇪 Ireland at $159,129.

🇱🇺 Luxembourg, 🇲🇴 Macau, and 🇳🇴 Norway round out the top six, ranging from $115,548 to $156,719.

Every country on this list has a population under 6 million — a pattern that holds across nearly every edition of this ranking, since a small population divides an economy's output among far fewer people.

💡 Worth noting: the global average GDP per capita, adjusted for purchasing power, sits at just $25,591 — meaning Liechtenstein's figure runs more than seven times the world average.

GDP per capita measures wealth generated. A completely different measure — one based on real reported prices and wages — asks how far that money actually goes.

🇰🇼 Kuwait posts the highest real-world purchasing power score of any country tracked, at 175.8 on Numbeo's index.

🇶🇦 Qatar follows at 168.1, and 🇨🇭 Switzerland at 165.7.

🇱🇺 Luxembourg, 🇴🇲 Oman, and 🇺🇸 the United States round out the top six, each scoring above 144.

Three of the top six are Gulf states — Kuwait, Qatar, and Oman — none of which crack the top ten on Section 1's pure GDP-per-capita ranking, showing just how differently these two measures can rank the same set of countries.

🔎 Worth sitting with: Singapore, the world's second-wealthiest nation by GDP per capita, scores just 91.3 on this real-world index — solidly average, and proof that raw national wealth doesn't automatically translate into locals feeling flush day to day.

For genuine contrast, here's where the same real-world index bottoms out.

🇨🇺 Cuba posts the lowest score of any country tracked, at just 2.4.

🇳🇬 Nigeria follows at 8.8, and 🇨🇲 Cameroon at 10.8.

🇨🇮 Ivory Coast, 🇪🇹 Ethiopia, and 🇸🇧 the Solomon Islands round out the group, each scoring below 14.

The gap between Kuwait's 175.8 and Cuba's 2.4 represents a difference of more than 73-fold — one of the widest disparities recorded on any economic index tracked in this newsletter.

📊 Worth remembering: several of these low scores reflect currency instability and dual-pricing systems as much as raw poverty — a resident's real spending power can be undermined by structural economic distortions even when wages, on paper, aren't the lowest in the world.

The AI IPO Rush Is Coming

OpenAI and Anthropic could bring a new wave of AI attention to the public markets. But investors don’t have to wait for the IPOs.

Depending entirely on which measure you use, a different country holds the title of "world's largest economy" — and the gap reveals something real about how PPP works.

🇨🇳 China's economy, adjusted for purchasing power, reached an estimated $41.02 trillion in 2025 — the largest of any nation on Earth by this specific measure.

🇺🇸 The United States, by contrast, leads in nominal (non-adjusted) terms, with a GDP of just over $30.6 trillion in the same year.

China's PPP-adjusted total pulls ahead specifically because prices for goods and services are lower there relative to America — the same yuan buys more locally than a straight currency conversion would suggest.

🔎 The nuance worth holding onto: neither ranking is "wrong" — nominal GDP better reflects a country's global purchasing power in international trade, while PPP-adjusted GDP better reflects the actual scale of domestic economic activity.

Zoom out to the entire planet, and the gap between the world's wealthiest nations and the global norm becomes genuinely stark.

🌍 The average GDP per capita worldwide, adjusted for purchasing power, sits at $25,591 as of 2026.

🇱🇮 Liechtenstein's figure of $195,372 represents more than 7.6 times that global average.

Even a mid-tier wealthy nation on Section 1's list, like Norway at $115,548, still runs more than four-and-a-half times the world average — a reminder of just how unevenly global economic output is actually distributed.

💡 Worth noting: more than half the world's countries fall below this global average figure entirely, since a small number of extremely wealthy nations pull the mathematical average well above what a typical country actually achieves.

To close, it's worth tracking not a snapshot but a trend — specifically, how the United States' share of total global economic output is actually moving.

📉 In 2024, the United States accounted for 14.88% of global GDP, adjusted for purchasing power.

📉 That share is projected to fall to 13.98% by 2030 — a decline of roughly one percentage point in just six years.

The shift doesn't necessarily mean American living standards are falling — it largely reflects faster growth elsewhere, particularly in large emerging economies, expanding the overall global pie faster than the US economy itself is growing.

🔮 A prediction worth holding onto: if this trajectory continues, economists expect the US share of global PPP-adjusted GDP to keep drifting slowly downward through the 2030s — not from American decline, but from the rest of the world simply catching up.

To close, it's worth returning to Section 1's third-place finisher, because Ireland's headline number hides one of the most well-documented distortions in all of global economic statistics.

🇮🇪 Ireland's official GDP reached €533 billion in 2024.

🇮🇪 Modified Gross National Income, or GNI* — a measure Ireland's own statisticians created specifically to strip out multinational accounting effects — came in at just €312 billion the same year.

That €221 billion gap is driven almost entirely by multinational corporations, particularly US tech and pharmaceutical firms, relocating intellectual property and profits to Ireland to take advantage of its low corporate tax rate — activity that inflates GDP without proportionally benefiting Irish households.

🔎 Worth remembering: economists nicknamed this phenomenon "leprechaun economics" after Ireland's GDP once jumped 34.4% in a single year, driven almost entirely by one company's accounting decisions — a reminder that even the most official-looking wealth statistics can measure something quite different from what residents actually experience.

Who has the highest purchasing power in the world genuinely depends on which question you're asking.

Liechtenstein and Singapore win on raw wealth per person. Kuwait and Qatar win on how far that money stretches in daily life. And China, by one specific and defensible measure, has already become the largest economy on Earth — even though most headlines still default to America holding that title.

None of these rankings is more "correct" than the others. They're just different lenses on the same underlying question: what does a unit of money actually get you, and where?

Stay informed, stay curious, and keep an eye on where your own money would actually go furthest.
