Manipulating a nation's currency sometimes appears to be a national sport. The rules change from country to country—conversion rates, exchange-rate pegs, quantitative easing, yield-curve control, debt issuance—but the underlying problem does not disappear. A government can change nominal claims and a central bank can change the terms on which money is supplied. Neither can repeal scarcity or prevent markets from adjusting somewhere else.
Change the quantity or price of money, and the adjustment may appear in inflation, interest rates, exchange rates, asset prices, credit or capital flows. The purpose of this series is to find out where it actually appeared.
German reunification turned a political currency conversion into a remarkable natural monetary experiment. We use the actual Deutsche Mark, interest-rate data, event dates and RainbowStats transfer-function analysis to revisit the Country A/Country B model.
Japan's crisis moved through four stages: trade-surplus recycling and balance-sheet expansion; the collapse of property and equity values; delayed recognition and zombie lending; and, finally, the migration of losses toward government debt and the Bank of Japan. Timelines, graphs and tables show how the burden moved from borrowers to banks and ultimately to the sovereign balance sheet.
Mexico held the visible volatility of the peso down while capital inflows, a widening current-account deficit and short-term dollar-linked debt increased the system's vulnerability. Political shocks drained reserves; Tesobonos transferred exchange-rate risk to the state; and the December 1994 break moved the loss into interest rates, inflation, banks and the real economy.
The yuan's unusually low volatility is quasi-evidence of intensive management—not proof of undervaluation, but a sign that policy is doing work. China's immense trade surplus must then be invested somewhere: in domestic construction, foreign reserves, gold, household prosperity or strategic and military power.
The article distinguishes China's aggregate power from household living standards, examines the allocation of national savings and warns about a modern Dreadnought dynamic. China can choose greater household prosperity and confident participation in an encompassing liberal order. The rest of the world must make that choice possible without abandoning reciprocity, sovereignty or law.
Britain did not preserve the economic world of the 1890s. Two world wars consumed the balance sheet supporting imperial power, while sterling, inflation, interest rates and fiscal policy distributed the adjustment across generations. The result was not national collapse but a long relative retreat managed through currency flexibility, institutional reform and a deep sovereign-debt market.
The analysis distinguishes absolute growth from declining GDP per person relative to the United States, traces sterling and the price of credibility, and places Brexit within the longer story: greater formal autonomy, continued economic constraint and survival without apocalypse.

Russia emerged from the Soviet collapse with strategic weapons, diminished living standards and a weakened state. Energy exports restored revenue and administrative capacity, but economic recovery did not produce convergence with the United States, demographic renewal or durable political competition.
The analysis follows oil production, real GDP per person, the ruble, trade, Russia's withdrawal from U.S. Treasury securities and its demographic constraint. It distinguishes Russia's formal multiparty framework from the effective concentration of power—and asks what that process should teach every democracy.

The United States emerged from the Second World War with unmatched productive capacity, gold reserves and monetary authority. It then tried to sustain three defensible objectives at once: military power strong enough to protect a liberal international order, social investment sufficient to support a mass democracy, and monetary and financial stability capable of financing both.
The analysis follows Eisenhower, Nixon, Carter, Reagan and their successors alongside Burns, Volcker, Greenspan and Bernanke. Thirteen charts and historical tables show how repeated stabilization prevented destructive collapse while shifting adjustment across inflation, debt, asset prices, labor and time—with political consequences that remain visible today.

Mexico supplied the warning. Thailand broke the assumption that managed Asian currencies were separate risks. A RainbowStats SUR analysis compares the covariance structure before, during and after the 1997–1998 crisis and shows Indonesia moving from near independence into a common regional liquidation.
The study connects the national stories: Thailand's baht defense, Malaysia's capital controls, Korea's bank funding, Indonesia's dollar debt, Russia's default, Brazil's float and India's partial insulation. The covariance matrix becomes a map of monetary interdependence.

Germany altered the conversion of monetary claims. Japan moved through four stages of a long-term financial crisis while spending decades influencing the price of capital. Mexico used an exchange-rate regime to anchor inflation until external imbalances and lost confidence overwhelmed it. China manages the exchange rate within a broader system of credit direction and capital controls, making unusual currency stability a question to investigate rather than an answer. The United Kingdom accepted sterling depreciation and institutional adaptation as imperial power gave way to a smaller but resilient state. Russia converted resource income into restored state capacity, financial insulation and military reach without achieving comparable economic convergence or political renewal. The United States repeatedly used money, credit and the public balance sheet to reconcile military power, social commitments and financial stability. The Asian contagion demonstrates how national vulnerabilities become a regional crisis when investors connect them through shared funding and their own balance sheets.
These episodes are not interchangeable. The useful comparison is narrower: each shows that monetary arrangements redistribute adjustment rather than eliminate it.
For each country we will ask the same questions. What policy variable was being controlled? What imbalance accumulated? Where did market pressure first appear? What did interest rates and the currency do? What happened when the policy changed? And, most importantly, can the historical data reproduce the story?
That last question is why this belongs on RainbowStats. Each article will emphasize equations, charts, historical event markers and reproducible analysis rather than relying on a monetary narrative alone.
