The expectation for interest rate hikes by the Federal Reserve has cooled, resulting in a three-day decline for the US dollar, reaching a new low since May, while the emerging market currency index has soared to a historic high.

As a series of disappointing economic data from the United States has completely extinguished market expectations for a Fed interest rate hike in September, global capital is re-pricing at the fastest pace in recent months. On August 17, the Bloomberg Dollar Spot Index fell for the third consecutive trading day, hitting its lowest level since May 15. Meanwhile, the MSCI Emerging Markets Currency Index briefly rose 0.2% to 1906.98, setting a new all-time high; the Emerging Markets Stock Index also climbed 0.6%, indicating a significant recovery in risk appetite. Data "Triple Blow": Probability of Fed Rate Hike in September Plummets from 75% to 30% The persistent weakness of the dollar is not coincidental. In just two weeks, three sets of key economic data have shattered market confidence in the Fed's continued rate hikes. First Blow: Unexpected Shrinkage in July Non-Farm Payrolls. Data released on August 7 indicated that the U.S. non-farm payrolls decreased by 23,000 in July, whereas the market had expected an increase of 80,000. The data for May and June was significantly revised downwards, amounting to a total downward revision of 103,000. Clear signs of cooling have emerged in the U.S. labor market. Second Blow: CPI and PPI Both Cool Down. July CPI and PPI figures revealed signs of fatigue. The inflation data has returned to a downward trajectory, further diminishing the urgency for the Fed to raise rates. Third Blow: Retail Sales "Cold Shock" Ends Nine Consecutive Increases. On August 14, it was reported that U.S. retail sales in July fell by 0.6% month-on-month, far below the market expectation of a 0.1% increase, ending a streak of nine months of growth. The control group for retail sales, directly related to GDP calculations, also recorded a 0.4% month-on-month decline. Consumer confidence index deteriorated due to rising living costs. The cumulative effect of these three sets of data was immediate. According to the CME FedWatch tool, the market's implied probability of a Fed rate hike in September has plummeted from about 75% in late July to 30%. The U.S. swap market is currently pricing in only a 25 basis points rate hike for January next year, which sharply contrasts with the market's prior expectations of a hike before year-end. The remaining expected hikes during the entire tightening cycle have now narrowed to about 36 basis points. Dollar "Loss of Momentum" and Emerging Markets "Carnival" The direct consequence of the weakening dollar is the widespread eruption of emerging market assets. Wee Khoon Chong, a senior strategist for Asia-Pacific markets at BNY Mellon, stated: "Emerging market currencies were supported today primarily by the weak dollar and the continued recovery in risk appetite in the stock market. We are seeing a strong inflow of foreign capital back into emerging markets, especially in Asia." Carry trade revival. As the Fed's rate hike path flattens, the relatively high interest rate advantage of emerging markets has re-emerged, attracting yield-seeking global capital. Geopolitical risk premium retreats. Galvin Chia, an emerging Asia strategist at French Industrial Bank, pointed out that the strength of Asian currencies is a result of multiple factors resonating: "Asian currencies seem to benefit from last week's weak U.S. data and the weakening of the dollar earlier this week. The absence of new geopolitical news over the weekend and Brent crude prices falling below $90 could also provide support to the market." The Dollar Index (DXY) has dropped to around 99.50, hovering near a two-month low. The euro has broken the key resistance level of 1.1577 against the dollar, standing above the 100-day moving average. The yen has rebounded to around 159 against the dollar. From a quantitative perspective, the correlation coefficient between Citigroup's U.S. Economic Surprise Index and the Dollar Index over the past 20 days is as high as 0.85, indicating that unexpected changes in economic data have become a core variable affecting dollar movements. Signals from the options market are even clearer. One-month options have for the first time since late February turned into bets against dollar depreciation, while longer-term contracts still favor the dollar. Key Variables This Week: Will FOMC Minutes Provide a "Hawkish Rescue"? Whether the dollar's decline can continue will hinge on two key events this week. Wednesday (August 20): FOMC July Meeting Minutes. At the Fed meeting on July 29, interest rates were kept unchanged within the range of 3.5%-3.75% for the fifth consecutive time, but three dissenting votes were notedDallas Fed President Logan, Cleveland Fed President Mester, and Minneapolis Fed President Kashkari all advocated for a rate hike. Chris Turner, global markets head at ING, remarked: "If the minutes contain some wording suggesting that the decision to keep rates unchanged might be closer than most expect, we believe it will be difficult for the market to completely revert to a hawkish stance." As Chong from BNY Mellon noted, foreign capital is "strongly rebounding" into emerging markets. Chia from French Industrial Bank cautioned that the end of the summer's low season combined with a vacuum of geopolitical news may have amplified current volatility. This week's FOMC minutes will be a critical litmus test for whether this trend can be sustained. If the minutes reveal the "reaction function" of the Fed under Powell's leadership, it could alter the market's judgment on the probability of rate hikes. Friday: PMI Data. If U.S. PMI figures show an expansion of its growth advantage, it may provide some support for the dollar. Elias Haddad, global market strategy head at Brown Brothers Harriman, noted that if robust U.S. economic data solidifies America's growth advantage, it could bolster the dollar. Emerging market currency indices setting historical highs, the dollar falling to a three-month low, and foreign capital once again flooding into Asian marketsthese changes seem to indicate a loosening confidence in the notion of "American exceptionalism."
