Back in the day, people used to joke that bankers followed the 3-6-3 rule: They borrowed money (deposits) at 3%, lent them out (through mortgages and other loans) at 6%, and were on the golf course by 3 o’clock in the afternoon.

While the banking industry has evolved dramatically in recent decades, the appeal of relatively effortlessly earning an interest rate spread between the cost of money on borrowed funds and the return on lending out that same money is timeless.

Enter the FX carry trade.

What is the FX carry trade?

As we outlined in our educational article on the topic, “a carry trade is a trading strategy that involves borrowing a low-yield (low interest rate) currency to buy a higher-yield (high interest rate) currency in order to profit from the difference in interest rates.”

Prior to the Great Financial Crisis (GFC), this was one of the most popular FX trading strategies on the planet, with many traders selling currencies with lower interest rates, like the Japanese yen, and buying currencies with relatively high interest rates, like the Australian dollar or even more exotic EM currencies like the Turkish lira. Even if the difference between the relevant rollover rates, say on AUD/JPY, were only 2.00%, by incorporating leverage, traders were able to collect sizable annualized interest rates. If the AUD/JPY exchange rate also rose, the carry trade would be even more profitable, though it’s worth emphasizing that a decline in the exchange rate could offset any profits or even lead to outright losses despite the positive carry.

Is the FX carry trade back?

The popularity of the FX carry trade took a big hit when most global central banks drove interest rates to essentially 0% in the aftermath of the GFC, but as inflation rises to multi-decade highs, some central banks are once again raising interest rates aggressively, suggesting that the carry trade could come back from the dead in the coming months.

For example, traders expect the Federal Reserve to raise the fed funds target rate to roughly 4.50% by the end of the year, whereas the BOJ is still aggressively intervening into Japan’s bond markets to ensure that interest rates on the 10-year JGB do not exceed 0.25%. In other words, the “gap” between the Fed and BOJ’s primary interest rates will likely approach 4.00% in the fourth quarter of this year, providing notable positive carry on a long USD/JPY position, especially when accounting for the potential leverage on the trade.

As the chart below shows, many traders have already been pricing in the positive carry potential with the pair, and USD/JPY has tacked on about 1,500 pips in the last two months alone.

For anyone considering placing a carry trade on USD/JPY, it is essential to monitor the price action in the underlying exchange rate, as a decline of just 3% (or about 350 pips in this case) could wipe out an entire year’s worth of interest, but as long as the pair remains well supported (or even rises further), the newly-rediscovered potential for positive carry in the FX market can provide a tailwind when trading certain pairs.

*September 23 edit: Note that the BOJ has intervened into the market to strengthen the yen, presenting another risk for long USD/JPY traders. As long as the interest rate differential remains large, the USD/JPY carry trade remains in play, but traders should avoid excessive leverage given the risk of continued intervention by the BOJ.
