SINGAPORE: An unwinding of global carry trades is turning into a rout that’s helping jolt markets around the world.

The yen and yuan pushed higher yesterday, while the Mexican peso extended its slump as traders continued to roll back the popular trading strategy.

The peso weakened 2.9% to the greenback, the worst performance among all currencies tracked by Bloomberg, while the Australian dollar pared some of its losses following a 2% drop.

Two currencies often used to fund carry trades jumped - the yen by more than 3% and yuan by 0.8%.

The moves came as a sell-off in risk assets intensified with markets including stocks and cryptocurrencies pummelled as concerns grew that the Federal Reserve is behind the curve with policy support for a slowing US economy. Investors sought the safety of bonds.

The sudden appreciation in funding currencies has damaged the carry strategy, which typically involves traders borrowing at lower rates to invest in higher-yielding assets often in the emerging world but also in developed markets like Australia.

Worries about US recession risk is a bad environment for carry traders, according to Alvin Tan, head of Asian currency strategy at Royal Bank of Canada in Singapore.

“Recession risk also means greater market volatility, hence carry trades being cut,” Tan said.

“I think it could easily extend because we have been in a extended low vol environment for so long, over a year in fact.”

For Tan, thin markets in the northern hemisphere summer may also be playing a role.

“August volatility spikes can be very dangerous because liquidity tends to be low in the month,” he added. “August is a popular vacation time in North America and Europe, so even if things start to stabilise, I’m not sure investors are going to be keen to put on trades quickly.”

Yen-funded carry trades were among the most popular in emerging markets as volatility remained low and investors bet Japanese interest rates would remain at rock bottom.

But the Bank of Japan raised rates for a second time at its latest meeting and signalled the potential for more.

“The rise of Japan interest rates is changing the game rules,” said Pierre-Yves Gauthier, head of research at Paris-based brokerage AlphaValue.

“In essence it’s the end of a free resource.”

Meanwhile, traders eyed the Chinese yuan as a funder given bets the currency would weaken amid concerns over the nation’s economy.

Year-to-date returns in a basket of emerging market currencies funded by the yuan turned negative yesterday, while the gain in yen-funded trades came closer to being erased, according to data compiled by Bloomberg.

“It will take quite some time for momentum to recover for those who have lost money on the peso-yen,” said Yoshio Iguchi, head of the market department at Traders Securities Co.

“Once the dollar and yen settle down, some people may start to carry the yen, but it may take some time for investor sentiment to recover.”

The closing of short yen positions represents a “real structural issue” with investors realising they will have to pay a positive interest rate and unwinding the trade as Japan is expected to raise interest rates at least one more time this year, according to Christopher Dembik, senior investment adviser at Pictet Asset Management.

“The issue at stake is not so much the market movement, it’s the scale, we’re talking about of sums which are enormous today on the carry trade,” he said.

“Of course, all the carry trade won’t be unwinded in a day but given the scale, it creates structural problems.”
