The weakening of the dollar has triggered a surge in carry trades, and emerging markets are about to face a "tsunami of funds."

Analysts have noted that the U.S. Treasury's bond buyback program has weakened the dollar, which may drive investors seeking new opportunities to pour funds into emerging markets. Last month, U.S. Treasury Secretary Janet Yellen doubled the size of the planned buyback of long-term U.S. government bonds to alleviate the upward pressure on long-term yields caused by market concerns over inflation and debt. Robin Brooks, a senior fellow at the Brookings Institution, stated in an article last week that the market is looking for places to "avoid the debt frenzy." Brooks indicated that as some major developed economies seek to lower long-term government bond yields, emerging markets are expected to see "huge inflows of capital," which will ultimately support arbitrage tradingborrowing cheap money to invest in higher-yielding assets. He pointed out that the biggest risk facing arbitrage trades, namely, a sudden spike in borrowing costs, has been alleviated by U.S. government intervention. Data from Toronto-Dominion Bank shows that in the week ending Wednesday, global emerging market bond funds recorded an inflow of $967 million, an increase of about 15% from the previous week, despite the overall slowdown in inflows for bond funds. As investors seek safe havens, gold prices have also benefited from Yellen's interventions, with institutions such as Deutsche Bank and Ray Dalio, founder of Bridgewater Associates, expressing support for the precious metal. Peter Kinsella, global FX strategy director at Union Private Bank in London, stated that the Treasury's announcement sent a signal to the market that "the U.S. may adopt policies similar to financial repression." He added, "This led to a weaker dollar, benefiting high-yielding G10 currencies and emerging market currencies." Data from the London Stock Exchange Group (LSEG) indicates that since Yellen announced the bond buyback, the South Korean won has strengthened by 2.83% against the dollar, the Brazilian real has risen by 0.64%, and the South African rand has gained 0.59%. Kinsella noted that favorable conditions for arbitrage trading, such as low volatility and a general decline in inflation, remain "firmly in place." He stated that among emerging markets, Brazil and Turkey are favored due to their continued high nominal yields and real yields after adjusting for inflation. He added that among G10 currencies, the Australian and Norwegian currencies are more favored. Brazil has one of the highest real interest rates among major economies, with a benchmark rate of 14% as of mid-August, while the 12-month inflation rate is 4.2%. The Turkish central bank maintained its one-week repo rate at 37% in July, despite the countrys annual inflation rate of 31.75%. Wee Khoon Chong, a macro strategist at BNY Mellon in Hong Kong, stated that Colombia has been "very popular" in arbitrage trading this year. As of last Friday, the countrys currency has appreciated by about 20% year-to-date, and its benchmark stock index COLCAP has also risen by about 20%. On the other hand, Eric Robertson, chief strategist at Standard Chartered Bank, said on Monday that the performance of Asian currencies is expected to continue lagging behind their emerging market peers. This has diminished the attractiveness of Asian currencies as investment targets. He pointed out that Asian currencies generally offer lower implied yields compared to other currencies, a trend that may persist if the Federal Reserve leans toward raising interest rates. India's central bank has one of the highest policy rates in Asia at 5.25%, but it is still only about one-third of Brazil's rate. Brooks noted that given that emerging markets have previously experienced a "massive outflow of capital" due to the Iran war, dollar-funded arbitrage trading is just beginning to unfold. He added that the Treasury's bond buyback announcement foreshadows that "more places may implement stronger measures over time."
