Carry Trade (Yen Carry Trade)
Borrowing the money of a low-rate country to invest where rates and returns are higher, pocketing the difference — the Japanese yen is the classic (yen carry). Its unwind shakes markets.
In plain terms
A carry trade "borrows money where interest is cheap and invests where interest or returns are higher," eating the difference. The Japanese yen, near 0% rates for a long time, is often borrowed, so the "yen carry trade" is the classic.
For example, borrowing yen nearly for free and putting it into US stocks or bonds gains you the rate differential. It is good while it runs smoothly, but when the mood changes it unwinds all at once and trouble follows.
What it tells you
A carry trade shows "how global money flows along rate differentials." When Japan holds rates very low, money borrowed in yen spreads to assets worldwide; when Japan raises rates or the yen suddenly strengthens, that money is urgently recalled.
When this "unwind" happens all at once, markets worldwide swing together (what actually happened in August 2024 is in the episode below).
Formula
carry trade = borrow a low-rate currency (e.g. the yen) → invest in higher-rate, higher-return assets → pocket the rate/return difference unwind = selling the assets and buying back the low-rate currency to repay the loan
What high or low means
When Japan holds rates low and the yen is weak, carry trades are active and money flows into risk assets. Conversely, when Japan raises rates or the yen spikes, unwind pressure builds.
A carry trade grows easily when US and Japanese rate directions diverge (US high, Japan low), so the two countries' rates have to be read together.
A carry trade has a "earns steadily when quiet, blows up big all at once" structure. Being an investment made with borrowed money, leverage is large, and if the exchange rate suddenly reverses, big losses and chain unwinds happen in an instant.
Its scale is hard to gauge exactly, making how far an unwind spreads hard to predict. So it is invisible in normal times and shakes the market badly when it blows.
A carry trade is macro/FX. This term is background for understanding market news. (※ Our screen handles individual companies' SEC-filed financials.)
In early August 2024, as the Bank of Japan raised rates and the yen spiked, the yen carry trade unwound all at once. Money that had borrowed cheap yen to invest worldwide was urgently recalled, dumping assets.
In the fallout, on August 5 Japan's Nikkei index plunged more than 12% in a day (its largest drop ever), and global markets including the US and Korea fell together. It was an event showing how fearsomely a normally quiet carry trade can shake markets when it unwinds.
