Dollar vs.
Euro.
Interest rates, money supply (M1/M2/M3), currency in circulation, and the EUR/USD exchange rate, straight from the Federal Reserve and the European Central Bank, refreshed weekly. No synthetic "which currency wins" score: the two central banks don't even disclose the same things (the Fed stopped publishing M3 in 2006; the ECB still does), so a single number here would hide more than it shows.
As of Oct 23, 2026, the Federal Reserve's policy rate is 3.88% and the ECB's deposit rate 2.50%, a gap of 1.38 percentage points. Euro area M2 was €16.45 trillion in August 2026 and M3 €17.65 trillion, up 3.87% on the year; US M2 was $23.34 trillion in August 2026, up 5.26%.
Where this data comes from, and what's not included
Every US figure here comes from FRED (the Federal Reserve Bank of St. Louis), the same free API this site already uses for the Crash Indicator and Macro Dashboard. Every euro-area figure comes directly from the ECB Data Portal, a genuinely free, keyless API: the European Central Bank's own published statistics, not a third-party mirror.
Left out on purpose, not overlooked: global reserve-currency share (the IMF's COFER survey) and private cross-border bank exposure by currency (BIS locational banking statistics) are both real, free datasets, but neither exposes a simple, documented REST query the way FRED and the ECB do. Rather than guess at an undocumented API shape and risk showing a wrong number, this page ships without them. They may be added later if a reliable query is found.
Germany's 10-year Bund yield stands in for "the euro-area bond yield": there's no single bond that represents all 20 euro-area countries at once, and the Bund is the conventional benchmark the same way the US 10-year Treasury is for the dollar.

Interest rate differentials, money-supply growth, and exchange rates are correlated in ways economists still actively debate; nothing here predicts where EUR/USD goes next.

Frequently asked questions
What is M2 money supply?
A broad measure of money: cash, checking and savings deposits and small time deposits. The euro area publishes M1, M2 and M3 monthly; the US publishes M2 (the Fed stopped publishing M3 in 2006).
What is a real interest rate?
The policy rate minus inflation. A rate of 3.88% means very different things when inflation is 3% than when it is 6%, so this page shows both the nominal and the real Fed and ECB rates.
Where does the data come from?
US data from FRED (St. Louis Fed) and euro-area data from the ECB Data Portal, refreshed weekly. There is no composite score: each series is shown as published, with its date.
About this dollar vs euro comparison
The dollar vs euro comparison puts Federal Reserve and European Central Bank policy rates, inflation-adjusted real interest rates, M1, M2 and M3 money supply and the EUR/USD exchange rate side by side, straight from the source and refreshed weekly. It is built to explain what moves the euro-dollar rate, not to predict it, and it never reduces the picture to a single composite score. For the wider market backdrop, see the stock market crash indicator, which tracks the yield curve and credit spreads, and the glossary for what each rate and money-supply term means.
