Economy, decoded
10 fundamentals · 5 briefs- Public debt hit $100T. Why it never stopsEvery year, thousands of companies merge or get acquired for trillions of dollars combined. Yet studies consistently find that most deals fail to deliver their promised value. This Fundamental breaks down how M&A actually works: why companies pursue deals, what due diligence really uncovers, why synergies are so often overpromised, and what separates the transactions that create lasting value from those that quietly destroy it.
- International trade and global value chainsYour smartphone was designed in the United States, built with components from Taiwan and South Korea, assembled in China, and shipped across three continents before reaching your hands. That journey is not an exception, it is how the modern economy works. Understanding global value chains, the return of protectionism, and the reshaping of supply chains is now essential for anyone trying to make sense of prices, jobs, and geopolitics.
- Cryptocurrencies and digital assets: the basicsBitcoin passed $100,000. Entire economies have adopted it as legal tender. Regulators worldwide are still trying to catch up. Before forming an opinion, it helps to understand what blockchain actually does, why crypto behaves the way it does, and what distinguishes a serious asset class from speculation.
- Economic growth: sources, drivers and limitsGDP has multiplied by more than tenfold in advanced economies since 1950. Yet forecasters now expect the next decades to look nothing like the last. What actually drives growth, why it slows, and whether the historical model can still hold, the foundational concepts behind every economic outlook.
- Economic inequalities: measurement and evolutionThe richest 1% now hold more wealth than the bottom 50% combined. But that figure alone tells you less than you’d think, what matters is understanding how inequality is measured, why different metrics yield different conclusions, and what the data actually shows about its evolution over time.
- Real estate: bubbles, investment and housing policyReal estate is the world’s largest asset class, and one of the least understood. Price-to-income ratios, cap rates, bubble dynamics, rent control, zoning: the concepts that explain why housing markets behave the way they do, in any country, at any point in the cycle.
- Financial markets: how stocks, bonds and prices workStocks, bonds, derivatives, indices, market makers, liquidity, financial markets have their own language, their own rules, and their own logic. A structured breakdown of how they’re organized, who the key players are, and what actually moves prices, beyond the headlines.
- Economic cycles: recession, expansion and bubblesEconomies don’t grow in straight lines. They expand, overheat, contract, and recover, in patterns that repeat, even if the triggers vary. How to read economic cycles, what the leading indicators actually signal, and why understanding this rhythm changes how you interpret almost any piece of financial news.
- Interest rates: how monetary policy moves the economyWhen central banks move their key rate by a quarter of a point, mortgage costs shift, currencies fluctuate, and stock markets reprice, sometimes within minutes. Understanding why that happens is the starting point for reading any major economic event of the past two decades.
- Inflation: mechanisms, causes and consequencesPrices rise, savings shrink, central banks react. Here is how the mechanism reaches you, and how to read it.
The World & Us
8 fundamentals · 5 briefs- Media and informationYou have never had access to so much information, and never trusted it so little. Behind that paradox lies an economic shift: advertising has left newsrooms for three platforms, and falsehood travels six times faster than truth. Understanding this link changes the way you read the news.
- Political systems and democracyFor the second year running, the planet holds more autocracies than democracies. Yet almost nobody openly rejects democracy. How can a model so widely desired retreat so fast? This Fundamental decodes the four main regime types, measures the scale of the shift, and reveals why decline no longer comes through coups, but through legal reforms.
- Demographic transition: aging, fertility, consequencesGlobal fertility has been halved over sixty years. At the same time, the share of people aged 65 and over has doubled. This dual shift is placing unprecedented pressure on pension systems, labor markets, and economic growth. The question is no longer whether this will happen: it already has.
- International migration: flows, causes and impactThe countries tightening immigration rules the most are often those facing the sharpest labour shortages. This paradox is no accident: it reveals the structural tension between economics, demographics, and sovereignty that migration has exposed for thirty years.
- Retirement systems: demographics, funding and reformIn 1970, every retiree was backed by more than five workers. Today that ratio has collapsed, and most people don’t realize their pension system was never designed to survive this shift. A complete breakdown of how retirement funding works, why it’s under pressure, and what reform actually looks like.
- International institutions: who really sets the rulesThe IMF, the World Bank, the WTO, the UN Security Council, these institutions shape global decisions that affect billions of people, yet most of us couldn’t explain what distinguishes one from another. How they were built, what power they actually hold, and where their limits lie.
- Natural resources: control, scarcity and geopoliticsOil, lithium, fresh water, sand: natural resources rarely dominate public conversation until prices spike or two countries go to war over their control. Understanding how they are distributed worldwide and what governs their value is the key to decoding a large share of global economic and geopolitical news.
- Global geopolitics: the forces that shape the worldEvery conflict, every trade dispute, every alliance makes more sense once you understand the underlying geography, interests, and power dynamics. A structured framework for reading the international order, from great-power competition to regional flashpoints, without a degree in political science.
Science & Futures
11 fundamentals · 5 briefs- 5G and 6G: how mobile networks really workYou were promised self-driving cars and connected factories. You mainly gained one extra letter on your screen. While China installs millions of antennas and two billion people stay offline, 6G is already being marketed to you. This Fundamental unpacks what 5G really changed, who benefits from it, and why the next generation arrives before the previous one kept its promises.
- Rare earths and critical materialsThey are in your phone, your car, every wind turbine. Yet one country refines 90% of the world's rare earths. How a handful of elements with no substitute became the silent weapon of the 21st century, and why neither recycling nor new mines will be enough in the near term.
- Water stress and scarcityOur planet is blue, and yet nearly 4 billion people run short of water every year. How does a seemingly infinite resource turn scarce? From India's aquifers to the Nile dam, this Fundamental decodes the mechanics of water scarcity.
- Semiconductors: technology and geopoliticsA single territory makes close to 90 % of the planet's most advanced chips, and no one can replace it quickly. Behind every smartphone, car and server hides a global chain of unexpected fragility. A 627-billion-dollar market, technical monopolies, a subsidy war: here is why chips now decide the balance of power between great nations.
- Cybersecurity and digital sovereigntyDefences have never been more effective, and yet cybercrime costs more than ever: around 10.5 trillion dollars in 2025. Behind every data breach lies an invisible battle for control of infrastructure, software and encryption. Understanding cybersecurity and digital sovereignty means grasping who really holds the keys to the connected world.
- Biotechnology and healthA blood disease can now be corrected at its root. The treatment comes close to a cure, but costs 2.2 million dollars. Yet 80 % of patients live where that price is out of reach. How did biotechnology move the frontier of care, and why is science no longer the main obstacle?
- Nuclear fusion: state of the art and commercial horizonIn December 2022, a fusion target released more energy than it received for the first time. Since then, more than $7 billion in private capital has flowed into the sector. But between the promises and commercial reactors, what obstacles remain, and what do realistic timelines look like?
- The new space economy: how private industry took overFor sixty years, space was a government monopoly. Then a handful of private companies cut the cost of reaching orbit by 95% in a decade. Who are these players, why are they betting billions on low Earth orbit, and what does that mean for everyone else on the ground?
- Climate change: science, data and projectionsThe science is settled. The projections, however, are not, they span a wide range of scenarios depending on choices made in the next few decades. What the IPCC actually says, what SSP and RCP scenarios mean in practice, and where the real uncertainties lie.
- The energy transition: technologies, stakes, timelinesRenewables are now the cheapest source of new electricity in most of the world. Yet fossil fuels still account for over 80% of global energy consumption. Understanding why the gap exists, and what it takes to close it, is the real foundation of the energy transition.
- Artificial intelligence: how it works and why it mattersMost people use AI tools daily without knowing what’s actually running underneath. Neural networks, large language models, training data, inference, the vocabulary is everywhere, the explanations almost nowhere. A clear, jargon-free breakdown of how modern AI actually works.
Building Business
5 fundamentals · 6 briefs- Private equity explained: buyouts, returns, controversiesPraised for its returns, accused of hollowing out the companies it buys, private equity now manages trillions. Behind the LBO lies a structure where debt amplifies gains as much as risks. The same leverage has built fortunes and triggered dramatic bankruptcies. How can one financial tool produce such opposite results? A data-driven look at an industry that quietly shapes jobs, savings and markets worldwide.
- Profitability and value creation: reading a companyA company can double its revenue and still grow poorer. Reported profit is not the cash in the bank, and EBITDA flatters more than it informs. Behind the words "profit" and "return" hide different measures that decide a firm's real fate. This Fundamental unpacks five indicators, from cash to return on capital, to learn how to read a company for what it is truly worth.
- Mergers and acquisitions: how M&A deals workEvery year, thousands of companies merge or get acquired for trillions of dollars combined. Yet studies consistently find that most deals fail to deliver their promised value. This Fundamental breaks down how M&A actually works: why companies pursue deals, what due diligence really uncovers, why synergies are so often overpromised, and what separates the transactions that create lasting value from those that quietly destroy it.
- Business valuation: how companies are pricedDCF, market multiples, asset-based valuation, Berkus, VC Method, business valuation isn’t one technique but a family of competing approaches that often produce wildly different numbers for the same company. Here’s how to read them, and when each one actually applies.
- How companies raise money: from love money to IPOEvery publicly listed company started with a bank transfer between friends or a maxed-out credit card. Between that moment and ringing the stock exchange bell lies a precise sequence of funding rounds, each with its own logic, its own investors, and its own trade-offs.
