"Dollar rebound ends emerging market currency bull market, hottest forex trading of the year cools rapidly"

The shift of the Federal Reserve hawks is reshaping the global foreign exchange market. With the new Federal Reserve Chairman Kevin Warsh releasing a strong hawkish signal at his first interest rate meeting, the US dollar has rebounded strongly. The emerging market currencies and commodity-exporting country currencies that have been the best performers this year are experiencing a collective reversal, and forex trading strategies that were highly sought after earlier in the year are rapidly cooling down. Warsh emphasized the central bank's mission to fight inflation at his first press conference after taking office, breaking market expectations of a dovish stance by the Federal Reserve. The futures market has already priced in a 25 basis point rate hike by the Federal Reserve before October, with the US dollar spot index rising by about 1% over the course of two days on Wednesday and Thursday, marking the largest two-day increase in three months. The Brazilian real, Australian dollar, and South Korean won have all fallen by over 2% against the US dollar in the past month, with the Norwegian krone falling by over 4%. This round of US dollar rebound is particularly significant for carry trade strategies centered around emerging markets. Investors who previously borrowed low-interest US dollars to buy assets in high-interest countries like Brazil are now facing pressure to unwind their positions, as US dollar assets regain attractiveness, further accelerating capital outflows. Hawkish debut breaks market narratives Warsh's first appearance has completely reshaped the market's expectations of the Federal Reserve's policy path. Previously, the market widely expected the Federal Reserve to continue its dovish stance, which was a key support for the pressure on the US dollar and the strength of emerging market currencies this year. Lee Hardman, a strategist at MUFG Bank, said that the Federal Reserve's hawkish update "is threatening to trigger a bullish breakthrough for the US dollar," with its impact surpassing the suppressive effect of the US-Iran talks agreement on the US dollar, according to Bloomberg. Alex Cohen, a foreign exchange strategist at Bank of America, called this meeting "undoubtedly hawkish, and therefore undoubtedly positive for the US dollar," while Jane Foley, head of currency strategy at Rabobank, said that this meeting has "reactivated" dollar bulls. US inflation has recently accelerated to around 4%, reaching a three-year high and doubling the Federal Reserve's 2% target. The AI investment boom and energy price shock are the main drivers. Shaniel Ramjee, co-head of multi-asset investments at Pictet, said, "The resilience of the US economy compared to what people expected a few months ago has been somewhat unexpected, and US real yields are also remaining quite strong." Carry trades face collective unwinding In the first five months of the year, the Australian dollar, Brazilian real, and Norwegian krone all saw gains against the US dollar close to 10%, driven by rising commodity prices due to the Middle East war and market expectations of Federal Reserve rate cuts. However, as expectations of Federal Reserve policy reverse, this logic chain is breaking. The core logic of carry trades involves borrowing low-interest US dollars to buy assets in high-interest countries. Brazil's benchmark interest rate is currently 14.25%, making it a popular destination for these trades. However, Lee Hardman pointed out that "higher US rates and a stronger US dollar have triggered a reversal in some popular carry trades." Currencies like the Malaysian ringgit and Canadian dollar are also affected by this round of adjustment. According to CFTC data compiled by Bloomberg, hedge funds, asset management firms, and other speculative funds collectively held $27.78 billion in long US dollar positions as of June 9, the highest since February 2025. Significant bullish buying in the options market Changes in positions in the options market visually reflect a sharp shift in market sentiment. According to Bloomberg, quoting multiple traders, hedge funds and leveraged funds have been heavily buying bullish US dollar options since Wednesday, with the volume of euro-US dollar options trading reaching the highest since March 3 this year, and the volume of pound-US dollar bullish options trading more than five times that of bearish options. Tobias Jungmann, head of FX options trading at Bank of America New York, said, "We are seeing a large amount of bullish US dollar options buying," with a focus on G10 currencies, where the current low implied volatility levels make it "attractive to establish a bullish US dollar position through options." James Swindell, senior FX options trader at Barclays, also said, "We are seeing a comprehensive surge in demand for bullish US dollar options, particularly in the euro-US dollar and pound-US dollar." DTCC data shows that volumes of euro-US dollar options trading have risen to the highest since March 3 this year, with large bullish contracts worth over 200 million euros trading almost twice as much as bearish contracts of the same size. Differentiation within emerging markets This round of adjustment is not a comprehensive blow to emerging markets, with clear internal differentiation. The depreciation of the South Korean won is partly due to factors at the stock market level - the strong performance of chip stocks such as Samsung and SK Hynix has led some institutional investors to reach concentration risks, with profit-taking pressure spilling over into the foreign exchange market. Meanwhile, currencies of energy-importing countries are relatively resilient. The Indian rupee, Indonesian rupiah, and Philippine peso have recorded gains in the past month, benefiting from policy support such as interest rate hikes or relaxed capital inflow restrictions by central banks. Kurt Knowlson, portfolio manager for emerging market debt at Aviva Investors, said, "What impresses me is that this is the first major oil shock that has not triggered a wholesale sell-off in emerging market currencies. Policy credibility has played an important role." Emerging markets are no longer a one-size-fits-all trade. Long-term logic remains unchanged, but short-term pressures persist Despite the recent pressures, fund managers generally point out that the fundamental aspects of emerging markets have significantly improved since the last Federal Reserve rate hike cycle from 2022 to 2023, with ample foreign exchange reserves, relatively strict fiscal discipline, and improved monetary policy credibility. While the J.P. Morgan Emerging Markets Local Currency Bond Index has risen by about 2% so far this year, Ramjee of Pictet said, "The long-term logic of emerging markets relative to developed markets, particularly the healthier balance sheets of the US, still holds true." However, in the short term, the direction of the US dollar remains a key variable. Ugo Lancioni, senior portfolio manager at Neuberger with assets under management of $57.6 billion, said that while the company remains bearish on the US dollar in the medium term, mainly due to overvalued valuations, "strong US macro data, inflation pressures triggered by the energy shock, and the AI investment cycle continue to provide support for the US dollar." It is worth noting that there is a clear divide in the market on the direction of the Japanese yen, with Japanese Finance Minister Satsuki Katayama warning that the government may take "bold action" against speculative exchange rate fluctuations, making bets on a bullish US dollar in that direction more cautious.
