Run the Numbers

Six professional tools, gauge sovereign risk, project a monthly ETF plan, compare tax and residency regimes, chart precious-metal and global house-price history, and model a private-equity buyout from entry to exit.

What this tool does

Risk Heatmap. See which countries carry the most financial, political and security risk. Every nation gets one 0–100 composite score from its government debt and political-stability rating, then open any country for its full Security & Risk Profile: organized crime, cyber preparedness and data-privacy status, each independently sourced.

How this index is built, and what each number means

Every country below shows two independently sourced, hard metrics, not opinion. The D&D Composite Risk Index (0–100) is then derived from them by a fixed, published formula:

Risk Index = 0.55 × Instability  +  0.45 × Debt Pressure
① Debt-to-GDP
General government gross debt as a share of GDP. Source: IMF World Economic Outlook, 2025 estimates.
② Political Stability
Estimate from −2.5 (low) to +2.5 (high). Source: World Bank Worldwide Governance Indicators, 2024 update.

Instability = (2.5 − stability) ÷ 5 × 100.  Debt Pressure = min(debt ÷ 200 × 100, 100). The composite is an editorial construct built for comparison and teaching: extreme debt in a reserve-currency economy (e.g. Japan, USA) is far less dangerous than the raw number implies, which is exactly why every country carries a written analysis below.

Cybersecurity · Stay private

The map stops at the border. Your data doesn’t.

You just saw how each country scores on cyber-preparedness and data-privacy law, and how quickly that protection thins out. Here’s the uncomfortable part: every time you connect from an airport lounge, a hotel Wi-Fi or a high-surveillance border, you inherit that country’s risk, not your own. A VPN encrypts the gap between your device and the open internet, the one habit that travels with you into every red zone on the map. These four are the ones we’d actually trust with the tunnel.

A VPN is a privacy tool, not an invisibility cloak · it hides your traffic from the network you’re on and masks your IP, but you still choose who to trust with it. That’s why independent no-logs audits and jurisdiction matter far more than flashy speed claims. Every provider below has been independently audited.

Two countries, head-to-head

Pick two countries and a time horizon, then choose whether you earn as a private person (salary) or through a company (revenue & profit). The tool projects what you actually keep, after tax, social contributions and local living costs, charts revenue against profit, and flags the real-world frictions in each place.

Precious Metals. Track the real price history of gold, silver and platinum since 1971, then read the economic forces behind every major surge and crash.

Logarithmic scale
Toggle S&P 500 or Inflation (indexed view) to compare metals against equities and the cost of living.
The moments that moved the metals
1971Turning point
Nixon closes the gold window

President Nixon suspends the dollar’s convertibility into gold, ending the Bretton Woods system. Gold, fixed at $35/oz since 1934, is set free to float, and the modern precious-metals market is born.

1979–80Surge
Stagflation and the Hunt silver corner

Runaway inflation, two oil shocks, the Iranian Revolution and the Soviet invasion of Afghanistan drove capital into hard assets. Gold’s yearly average leapt from $307 to $615 (~$850 intraday); silver rocketed toward $50 as the Hunt brothers cornered half the deliverable supply, until ‘Silver Thursday’ halved it in a day.

1980–82Crash
Volcker breaks the fever

To kill double-digit inflation, Fed chair Paul Volcker pushed interest rates toward 20%. Sky-high real yields and a strong dollar made non-yielding metals unattractive, beginning a 20-year bear market, gold roughly halved, silver fell ~75%.

1999–2001Bottom
‘Brown’s Bottom’

Two decades of decline bottomed near $250–280/oz. Britain sold half its gold reserves at the lows (forever nicknamed ‘Brown’s Bottom’), and the Washington Agreement capped central-bank selling, quietly marking the floor.

2001–11Bull market
The crisis-and-QE decade

The dot-com bust, 9/11, a commodity super-cycle, the 2008 crash and years of zero rates and quantitative easing powered a historic run. Gold climbed from ~$271 to a September-2011 peak near $1,920; silver revisited ~$48.

2008Crash
Platinum’s blow-off top

Rarer than gold and tied to car exhaust catalysts, platinum spiked to ~$2,290 intraday in March 2008, then collapsed as the auto industry seized up in the financial crisis, its annual average sliding from $1,572 to $1,205.

2013Crash
Gold’s taper-tantrum plunge

When the Fed signalled it would slow QE and stocks surged, gold fell about 28% on the year. Its worst since 1980, as investors rotated out of ‘safe’ assets. Silver fell even harder.

2015Structural break
Dieselgate sinks platinum below gold

The VW diesel-emissions scandal gutted demand for diesel cars, platinum’s biggest market, while the shift to gasoline (palladium) and EVs kept it down. Once pricier than gold, platinum has traded below it ever since.

2020Surge
Pandemic stimulus, record gold

COVID unleashed vast fiscal and monetary support and drove real yields deeply negative. Gold smashed its 2011 record, topping ~$2,075 in August 2020.

2022–25Surge
Central banks and de-dollarization

Even against steep rate hikes, gold soared, driven by record central-bank buying (led by China), the war in Ukraine, and a global pivot away from the dollar. Its annual average rose from ~$1,800 to ~$2,860, notching record after record.

The D&D take · our analysis

Gold is not really an investment. It is insurance against the system that prices every other investment. Read the eight events above again with one lens: metals do not move on jewellery demand or mining news. They move on three forces. Real interest rates, when inflation-adjusted yields fall, gold rises (1970s, 2020); when they spike, it drops (2013). Confidence in money itself, 1971 and the current central-bank buying wave are the same event in different costumes: official institutions hedging the currency system they operate. And for silver and platinum, industry · Dieselgate did to platinum what no interest rate ever could, because platinum is a car part wearing a bullion costume.

What you can take from this today: first, when you see a gold headline, check real yields before any other explanation. That single relationship explains most of the chart above, and it turns confusing news into a readable signal. Second, stop treating the three metals as one asset: gold is monetary insurance, silver is a volatile hybrid, platinum is an industrial bet. The correlation table above shows they are different products sharing a shelf. Third, respect the flat decades: from 1980 to 2000 gold went nowhere while stocks compounded, history’s verdict is that metals preserve wealth through crises but do not create it between crises. Insurance, not an engine. Size it like insurance. That is not investment advice. It is what half a century of the data above says.

What this tool does

Global Property. Trace real (inflation-adjusted) house prices across the major economies since 1975, then read the booms, busts and the affordability crisis behind them. Real estate is the world’s largest store of wealth: around $380 trillion, more than all listed equities and bonds combined.

Real house prices
Booms, busts and the price of a home
1975–90The long ascent
Half a century of rising prices begins

Rising incomes, mass urbanisation and financial deregulation lifted real house prices across the rich world, nowhere more than Japan, inflating history’s most famous property bubble.

1991Japan’s bubble bursts
The cautionary tale of a generation

At the 1990 peak, Tokyo land was so inflated that the Imperial Palace grounds were said to be worth more than all of California. Bank-of-Japan rate hikes pricked it; urban land fell ~70–80% over the decade, and Japanese real house prices still sit below their 1990 peak today.

1997–2006The great global boom
Cheap credit inflates the world

Falling rates, mortgage securitization and loose lending drove a synchronized boom. US real prices climbed nearly 40% into their 2006 peak; the UK, Spain, Ireland and Australia ran hotter still.

2006–12Subprime & the Great Recession
The deepest crash since the 1930s

The US bubble burst first, real prices fell ~27% from the 2006 peak to the 2012 trough, and subprime losses detonated the 2008 global financial crisis, sinking housing across the US, UK, Spain and Ireland.

2010sThe great divergence
One crisis, many recoveries

Recovery split the world: the US, UK, Australia and Canada raced to new highs while southern Europe stagnated, and Germany, flat for two decades, began a historic catch-up surge as ECB rates hit zero.

2020–22The pandemic boom
A worldwide race for space

Zero rates, stimulus and lockdown demand produced one of the largest synchronized booms on record, three-quarters of the 60+ countries in the IMF’s index rose, and US prices leapt ~43% in barely two years.

2022–23The rate shock
The music stops

The fastest rate-hiking cycle in decades sent mortgage costs soaring and stalled the boom. Prices slipped from their 2022 peak in many markets, yet stayed far above pre-pandemic levels.

TodayThe affordability crisis
Homes outrun wages

Real prices have far outpaced incomes: price-to-income ratios sit near records in Canada, Australia, New Zealand and much of Europe, pricing out a generation and turning housing into a defining political fault line.

The D&D take · our analysis

Housing is the only asset ordinary people routinely buy with 5-to-1 leverage, which makes this chart more personally important than any stock index. The pattern above is not random: the long ascent was built on credit expansion and urbanisation, and every break in it · Japan 1991, the US 2008, happened where leverage met the assumption that prices only rise. Japan is the chart’s quiet warning: a generation later, real prices never returned to their 1990 peak. “It always comes back” is an American memory, not a law of nature.

What you can take from this today: first, judge any housing market, including yours, by the two ratios history actually punished: price-to-income and price-to-rent versus their own long-run averages; the chart above is inflation-adjusted precisely so the money illusion cannot hide them. Second, remember what leverage does to the picture: at 5-to-1, a 20% price dip is a 100% loss of your equity · Japan and 2008 were not price events, they were leverage events. Third, use the yield calculator above the way a landlord’s accountant would: net yield after all costs versus your financing rate. If that spread is negative, you are not investing in property. You are betting on appreciation, which is exactly the bet 1991 and 2008 settled. Educational framework, not advice, but it is the framework the last fifty years of data supports.

New to this? What private equity actually is

Private equity (PE) firms raise money from big investors, pension funds, insurers, university endowments, the very wealthy, and use it to buy entire companies. They spend three to seven years making each business more valuable, then sell it. The move that defines the industry: they pay mostly with borrowed money, a leveraged buyout, or LBO, because debt multiplies the return on the sliver of their own cash they put in.

It matters more than most people realise. PE manages over $8 trillion worldwide and owns tens of thousands of companies, hospitals, gyms, software firms, supermarkets, employing millions. It is where a large chunk of pension money quietly works, and a dominant force in global dealmaking. It is also divisive: the debt and cost-cutting that lift returns can also put companies under strain. A typical deal aims to double or triple its equity in about five years, a 20%+ annual return. Below, build one yourself.

1
Grow the business

Raise EBITDA: win customers, widen margins, bolt on smaller rivals. A bigger business sells for more.

2
Pay down debt

The company’s own cash flow repays the loan. As debt shrinks, the equity slice the fund owns grows, even if the business stays flat.

3
Buy low, sell high

Exit at a higher valuation multiple than you paid (‘multiple expansion’). Powerful, but the least reliable lever, because it depends on the market.

How much do you pay? It all comes down to the multiple

A company’s price is quoted as a multiple of its yearly profit, the EV/EBITDA multiple. Pay for a business earning $50m and its Enterprise Value is $400m. But the ‘right’ multiple swings enormously with four forces:

Sector

Software and healthcare change hands at 12–18×; retail, energy and heavy industry closer to 5–8×. Pick a sector in the tool below and watch it move.

Size · bigger is dearer

A small $5m-EBITDA business might fetch just 4–6×; a $50m mid-market company 8–11×; a $500m+ large-cap 12–15× or more. Big companies look safer, draw more competing buyers, are easier to finance and harder to find, a ‘size premium’. Small ones carry an illiquidity and key-person discount.

Growth & quality

Fast-growing, high-margin, recurring-revenue businesses earn a premium; cyclical or shrinking ones a discount.

The market

When debt is cheap and buyers are plentiful, multiples inflate across the board, and deflate when money tightens.

This powers one of PE’s favorite plays · buy-and-build: acquire several small companies cheaply (say 5–6×), merge them into one larger group, and sell the whole at a higher multiple (say 9–10×). You earn that gap on every dollar of profit, ‘multiple expansion’, on top of the growth itself. (This tool conservatively assumes you sell at the same multiple you paid.)

Where does the money come from? The capital stack

A buyout is funded in layers. In good times everyone is paid; in trouble, the bottom layer is repaid first and the top absorbs the first losses. That pecking order is why the cost of each layer climbs as you move up, more risk demands more reward.

↑ Higher risk & return · repaid last
Equity, the PE fund + management
Wants: everything left over. Takes the first loss and keeps all the upside. Targets 20–25%+. This is the slice the IRR & MOIC below measure.
Mezzanine, specialist private investors
Wants: high interest (12–18%, often part ‘PIK’) plus warrants for ~2–5% of the shares, an ‘equity kicker’. The bridge between debt and equity: it lends money and takes a piece of the upside. Used to stretch leverage beyond what banks will give.
Private credit, direct-lending funds (Ares, Blackstone, Apollo…)
Wants: higher interest (~SOFR + 5–7%). A market of nearly $2 trillion that barely existed in 2009 and now rivals the banks, faster, more flexible and confidential, for deals banks won’t touch.
Senior secured debt, banks & the syndicated-loan market
Wants: interest only (~SOFR + 4–6%) and its money back first, secured on the company’s assets. The cheapest money, roughly 3–5× EBITDA of it. Since the Basel bank rules tightened, much of it is now sold on to institutions.
↓ Lower risk · repaid first

The punchline: banks and senior lenders just want their interest and their money back. They never share in the upside. The higher up the stack, the more risk is taken, so private-credit and mezzanine investors demand higher yields, and mezzanine often wants a slice of the equity too. Switch the debt source in the tool below and watch the cost, and your return, change.

Illustrative LBO model. Entry multiples reflect typical 2024 sector levels (software ~15×, overall ~11×; sources: Ropes & Gray / PitchBook). Assumes a 5-year hold, exit at the entry multiple, ~8% debt cost and ~50% EBITDA-to-cash conversion for debt paydown. A teaching model, not investment advice.

Historical Context

Debt Through
the Centuries

National debt is not a modern invention. It is a story that begins with a war, a banker, and a promise. What follows is 330 years of that promise being tested, broken and renegotiated.

Every crisis in this timeline has a modern echo. Once you see the pattern, you cannot unsee it.

1694
England Invents the Central Bank

The King needed £1.2 million for war. A group of merchants agreed, in exchange for the right to issue money. The Bank of England was born, and nothing in finance was ever the same again.

1815
Post-Napoleon: Europe's Debt Mountain

25 years of continental war left national debt at ratios that look familiar to anyone watching Japan today. The Rothschilds stepped into the vacuum and built an empire from the rubble of someone else's default.

1944
Bretton Woods: One Hotel, One New World Order

44 nations. One New Hampshire resort. Three weeks of argument. The result: the dollar became the world's reserve currency, and every government on earth became, in some sense, a debtor to Washington.

2012
Greece: The Eurozone's First Sovereign Default

€107 billion erased overnight. The first eurozone member to force a debt haircut. It was not an accident. It was the end of a story that began in 1832, when Greece borrowed to fight for independence and never quite finished paying.

Why History
Needs Numbers

"Ideas build nations. Education builds ideas."

Debt & Dynasties started with a frustration I could not shake: why is history told without its financial skeleton, and economics without its historical spine? The most important events in human civilisation have a monetary root. Wars are borrowed into existence. Empires are sustained by credit. Geography determines who lends and who borrows.

I built this platform because nobody had put those three things, finance, history, geography, in the same room and made them genuinely accessible. Not a textbook. Not a lecture. Something you actually want to read.
