Gurus present the carry trade as a simple way to collect passive interest. They tell you to borrow a low-interest currency and buy a high-interest one. They call it free money. What they hide is the relational volatility. The moment the market panics, carry trades unwind in minutes, and the funding currency appreciates rapidly. Your yield gets devoured by exchange losses. The yield formula is simple subtraction.
The return on a carry trade is determined by the interest rate differential and the exchange rate movement. If you borrow currency A at rate iA and invest in currency B at rate iB, your net interest yield is the difference:
Yield = iB - iA
If the exchange rate B/A depreciates, the loss in exchange rate can exceed the interest yield. This risk is non-linear. When volatility increases, carry trades are rapidly unwound, leading to a sudden appreciation of the funding currency (A). This unwinding displaces the coordinates on the Cartesian plane. The carry trade is a ticking bomb when coordinates approach structural boundaries.
By projecting yield differentials onto the Cartesian plane, you can visualize the carry trade as a force vector. The coordinates of high-yield currencies are pulled towards specific regions of the Price Cloud, while low-yield funding currencies are pushed towards others.
This spatial mapping allows you to identify when a carry trade configuration is reaching its limits. By measuring the distance to exclusion zones, I calculate when the unwinding is likely to occur, allowing you to position your trades before the volatility spike. Either you calculate the coordinates of yield or you get caught in the panic.
