With the U.S. June CPI data rebounding for the first time in three months, market concerns about the gradual impact of tariffs are emerging, leading to a delay in interest rate cut expectations, which correspondingly caused a rebound in the U.S. dollar index and dollar interest rates. Although since the second quarter, the market has consistently been bearish on the dollar index and has been buying non-dollar currencies on dips, every rise in the dollar index has been viewed as a rebound rather than a reversal. However, compared to the early stages of de-dollarization trading in April and May, the current momentum of the euro and yen indicates that the sentiment of selling dollars on highs is loosening. I believe that this time we need to be wary of the risk of a dollar reversal for the following three main reasons:
<img src="https://imageproxy.pbkrs.com/https://wpimg-wscn.awtmt.com/ce3fac0a-bbf3-4527-82ff-1fcbe4550552.jpeg?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" alt="" original-src="https://imageproxy.pbkrs.com/https://wpimg-wscn.awtmt.com/ce3fac0a-bbf3-4527-82ff-1fcbe4550552.jpeg"/>
First, the sustainability of the &#34;de-dollarization&#34; trading theme
Since the second quarter, the biggest trading theme in the market has been &#34;de-dollarization&#34;—Trump's reciprocal tariffs and erratic subsequent policies, along with frequent interference in the independence of the Federal Reserve, have impacted the credibility of the dollar, leading overseas funds to collectively flee dollar assets.
However, from a time cycle perspective, the de-dollarization theme has been ongoing for over three months, and the market, which has become aesthetically fatigued, is in dire need of new topics. So, if CPI remains high, could tariff-induced inflation be the next topic?
Furthermore, from the perspective of the de-dollarization theme itself, it was previously widely believed that overseas funds increasing their dollar exposure for hedging was one of the reasons for the dollar's decline. However, according to recent research by Deutsche Bank, investors who are hedging have raised their hedging ratios to a considerable level, while other investors, constrained by execution, are adjusting their hedges slowly, making their foreign exchange hedging a slow and long-term process.

Second, technical aspects and position holdings
From a technical chart perspective, EURUSD has broken below the upward trend line since March on the daily level, with a MACD death cross indicating potential adjustment demand.

This is corroborated by Citigroup's recent weekly fund position data, which shows that euro shorts are accumulating. It is also worth noting that leveraged money is going long on the dollar.

Looking back at the dollar index, it has currently broken through the 20-day moving average, with the next target corresponding to the 50-day moving average around 98.8. Since February of this year, the dollar index has consistently operated below the 50-day moving average, and once it completes an upward breakout, it will signal a dollar reversal
Of course, achieving this will be inseparable from the corresponding decline of the euro, the largest component currency of the US Dollar Index.

Third, interest rate differentials and interest rate cut expectations
Before the end of the month, there will be a vacuum period for important US data, making it easier for the market to continue the perspective that &#34;tariffs will affect inflation.&#34; Therefore, the possibility of a rate cut in September must be questioned (unless the story of Powell stepping down continues to develop). Against the backdrop of relatively resilient hard data in the US and a rebound in CPI, the fundamental advantages and interest rate differential advantages will further support the US dollar—currently, the correlation between EURUSD movements and interest rate differentials is starting to revert, which means that if US dollar rates trend upwards, EURUSD will also be under pressure.

In summary, whether analyzing the sustainability of the &#34;de-dollarization&#34; main line or from the perspectives of technical analysis, positions, and interest rate differentials, the US dollar has established preliminary conditions for a reversal. So, will the first event to trigger this be the Japanese Senate election this weekend?

With the rebound of the U.S. June CPI data, concerns about the risk of a dollar reversal have intensified in the market. Although the market is generally bearish on the dollar, the momentum of the euro and yen shows that the sentiment of selling the dollar on rallies has eased somewhat. Analysts believe that the sustainability of de-dollarization trades, the need for technical adjustments, and the breakout of the dollar index may indicate the risk of a dollar reversal

- The U.S. CPI data rebound in June has raised concerns about tariffs, delaying interest rate cuts and leading to a rebound in the dollar index and rates.  
- The article highlights three reasons for potential dollar reversal: the ongoing "de-dollarization" trend, technical indicators showing a need for adjustment, and the impact of interest rate differentials amid a data vacuum before key U.S. reports.  
- Overall, the analysis suggests that conditions for a dollar reversal are emerging, with upcoming events like the Japanese Senate election potentially acting as catalysts.
