On Thursday, July 16, the US dollar index remained in a narrow range after the release of retail sales data, last quoted at around 100.60. The index had previously fallen by approximately 0.8% over two consecutive trading days, mainly due to cooling inflation data and a pullback in expectations of a Federal Reserve rate hike. US retail sales rose 0.2% month-on-month in June, a significant slowdown from the revised 1.0% in May, but largely in line with market expectations. The data did not produce any strong directional surprises, and the dollar index thus failed to break out of its tug-of-war within the 100.35 to 101.30 range.

The slowdown in retail sales is not a real signal of 0.2%.

June retail and food service sales totaled $768.6 billion, up 0.2% month-over-month and 6.7% year-over-year; cumulative sales from April to June increased by 6.4% year-over-year. It's important to note that this statistic is adjusted for seasonality, holidays, and trading days, but does not exclude price changes. Therefore, the nominal year-over-year growth rate of 6.7% cannot be directly equated with actual consumption expansion. More importantly, the 0.2% month-over-month increase corresponds to a 90% confidence interval of ±0.4%, which is statistically insufficient to confirm a true increase in sales for the month. This means the market should not judge continued strong consumption solely based on superficial positive growth. The May growth rate was revised upward from 0.9% to 1.0%, creating a high base, and the June decline was somewhat technical; however, structurally, consumption momentum is indeed becoming more concentrated. Sales at automobile and parts dealerships increased by 1.9%, non-physical retail sales increased by 1.9%, sporting goods, hobby products, musical instruments, and bookstores increased by 1.3%, and electronics and home appliance sales increased by 0.8%. The significant contributions from automobile and online sales indicate that the overall growth has not stalled, but the expansion of broad-based demand is limited. Non-physical store retail sales grew by 14.2% year-on-year, further reflecting the continued concentration of consumption in online channels. For the US dollar index, this data combination neither reinforces the narrative of a rapid economic slowdown nor is sufficient to re-establish a tightening premium. Nominal consumption growth provides a floor for the dollar; declining month-on-month momentum limits further increases in short-term interest rates, ultimately resulting in a market outcome with limited volatility after the data release.

The core of dollar pricing has shifted to expectations of real interest rates.

Recent consumer and producer price data have both fallen short of market expectations, reducing the necessity for the Federal Reserve to raise interest rates immediately at its July meeting. The market is pricing in nearly 90% of a rate hike in July, expecting it to remain within the 3.50% to 3.75% range. Against this backdrop, retail sales, merely in line with expectations, are unlikely to significantly raise terminal interest rate expectations or push the 2-year yield above its recent range. The US dollar is currently facing a divergence between growth and inflation signals. Total consumption remains high, preventing the market from quickly pricing in an economic recession; marginal declines in inflation, however, are suppressing the probability of a rate hike. Unless real interest rates continue to rise, the dollar index rebound is more likely to be a mean reversion within its range rather than a unilateral trend expansion.

Technical indicators suggest that the price is entering a repricing zone above the 100 level.

The daily chart shows that the US dollar index previously formed a high near 101.80, and subsequent rebounds failed to break through 101.30, with short-term highs gradually shifting downwards. The latest price is around 100.60, having broken below the Bollinger Band middle line at 100.81, but still above the lower line at 99.68. The index is in the lower half of the Bollinger Bands, indicating short-term pricing weakness, but it has not yet entered a state of uncontrolled volatility. In the MACD indicator, the DIFF is around 0.1977, lower than the DEA at around 0.3217, with a histogram value of around -0.2480, reflecting a continued contraction in upward momentum. It is worth noting that both the DIFF and DEA are still above the zero line, indicating that the medium-term structure has not yet fully turned bearish, but is closer to the end of an upward cycle with weakening momentum. 100.35 is a clear recent low in the price structure, and the area around 100.55 has repeatedly formed intraday support; together, they constitute a short-term demand zone. Above, 100.81 corresponds to the Bollinger Band middle line, while 101.30 is the recent rebound high. If the index remains below 100.81 for an extended period, the market will continue to reduce the dollar interest rate premium; only a return above 101.30 will indicate that retail sales and subsequent data are driving a substantial change in interest rate expectations.

Subsequent variables will determine whether the interval can be broken.

Retail sales are not the sole basis for the Federal Reserve's assessment of consumption. This indicator does not include most service spending and does not eliminate price factors; therefore, subsequent personal consumption expenditures, employment, wages, and consumer credit data are more reliable indicators of the true affordability of the household sector. The main contradiction currently facing the US dollar index is that nominal consumption remains resilient, but marginal growth, inflationary pressures, and policy expectations are all cooling simultaneously. If core consumption and employment remain stable, while energy costs re-push inflation expectations, US Treasury yields may find support, and the US dollar index will retest its upper resistance level. Conversely, if real consumption, wages, and hiring weaken simultaneously, the market focus will shift from whether to continue raising interest rates to the duration of high interest rates, significantly increasing the importance of the 100 level.
