1 / 9

When you use the same money, your country has less it can decide on its own.

You give up three things: exchange rates, interest rates, and how much money to print.

2 / 9

There's only one interest rate. It's too low for countries with good economies and too high for countries with bad economies.

This isn't a failure; it's just what happens when you unify.

3 / 9

1433, Low Countries

Four regions began to seriously use a common silver coin.

The agreement from 1339 was broken, but it set a precedent.

4 / 9

July 1, 1990

East and West German money was exchanged at a 1-to-1 rate.

It was a political decision, not an economic calculation.

5 / 9

1990

The savings of people in the East were protected. It became a heavy burden for factories in the East.

The miracle and the cost were two sides of the same decision.

6 / 9

1992

The fixed exchange rate was seen as 'indefensible,' and the pound collapsed.

Black Wednesday. Some later called it White Wednesday.

7 / 9

1999

The value of one euro was permanently fixed in francs. It's not rounded because it will never change.

6.55957 francs

To the 5th decimal place.

8 / 9

2002

The franc and the guilder were no longer legal tender.

The system ends first, and the habit of using it disappears later.

9 / 9

Now

German mark banknotes can still be exchanged for euros today, with no deadline.

Even if the system is over, the promise lives on.

3What would you do?

You found an old German mark banknote in the back of a drawer. The mark is no longer legal tender. What do you do?

Pick one

Throw it away, thinking it's worthless paper.

What a waste! German marks can still be exchanged for euros at Germany's central bank with no deadline.

Take it to the bank.

Even today, you can exchange it for euros at a fixed rate. The promise to exchange lives on, even if it's no longer legal tender.

Assessment

11 exercises in this course (7 check, 1 compare, 3 written). Progress is recorded by self-assessment.

The 8 chapters of this course
  1. What you give up by joiningIn monetary union you give up the exchange rate, the interest rate and the quantity issued. Only the budget stays yours.
  2. The exchange ratio is sometimes decided by politicsThe conversion ratio is sometimes settled by politics. Do not confuse the economic sum with the political decision.
  3. A fixed rate is a target for the stormA fixed rate becomes indefensible the moment people think it cannot be held. Union does not remove the problem; it moves it.
  4. When a currency goes, what remainsA currency's legal death and its disappearance from custom do not coincide. Read the two apart in the records.
  5. A broken promise, a lasting precedent — Seven hundred years in the Low CountriesTo attempt unification and fail. This repetition becomes the groundwork for a great integration to come later.
  6. One-to-One Politics — The East's Hoard and the West's LedgerThe exchange rate was not an economic calculation but a political declaration. The miracle and its cost were two sides of the same decision.
  7. Black Wednesday — The Day the Fixed-Rate Net Was BrokenA system that merely links separate currencies will strain with every storm. The day of defeat was also renamed the day of liberation.
  8. Tracing a defunct currency's lineage — Defining its deathThe end of legal tender, exchange deadlines, and the fulfillment of promises. A currency's "death" has at least three dates.
