Stanley Druckenmiller / 1990 / Macro
A new country. A new price.
Stanley Druckenmiller and the currency implications of reunification.
Before the outcome was obvious.
German reunification was a political event with a monetary shadow. The workbook’s Deutsche Mark case focuses on reunification spending and the consequences for policy. The investment question is one step removed from the headline: how might a change in spending alter interest rates, capital flows and demand for a currency? This is the attraction of macro investing, and also its difficulty. A major event can be obvious while its market consequences remain contested.
What could have gone wrong
Growth, fiscal policy and central-bank responses can pull a currency in different directions. The obvious story can already be in the price.
Work through the second-order effects before choosing the position.
Put the thesis to the test.
Change the assumptions and watch the arithmetic update. These are simplified scenarios; they do not recreate the instrument’s pricing or the path of the trade.
How this model works
Profit ratio = profit ÷ stated position. Exposure ratio = stated position ÷ fund assets. Neither is a measure of maximum loss or a net investor return.
The workbook’s simple annualisation is profit ratio × 365 ÷ duration = 60.8%. It is linear, not compounded, and is not a repeatable annual return. Fees, financing, collateral, premium carry and changing exposures are not modelled.
What these figures mean.
