During Asian trading on Monday, the U.S. dollar index (DXY) remained weak, holding near the 99.50 level and lingering around its lowest point in nearly two months. A string of weaker-than-expected economic indicators, led by a surprise 0.6% monthly drop in July retail sales compared to the forecast of a 0.1% gain, is prompting traders to sharply reduce bets on a Federal Reserve rate hike. According to the CME FedWatch Tool, the implied probability of a rate increase in September has fallen to 33%.

Meanwhile, U.S.-Iran negotiations remain deadlocked, with Iran's foreign minister explicitly stating that "no talks are currently underway with Washington." While this geopolitical risk provides some safe-haven support for the dollar, it has not been enough to reverse the greenback's overall weak trajectory.

The disappointing retail sales data, which showed a 0.6% month-over-month decline in July after a 0.2% increase in June, and a year-over-year slowdown to 5.0% from 6.8%, followed last week's soft CPI and PPI figures. This reinforces a narrative of cooling economic growth and inflation. The CME "FedWatch" now shows a 66.9% probability of the Fed holding rates steady in September, with a 33.1% chance of a 25-basis-point hike. Analysts at BNY Mellon noted that the softer U.S. data has reduced rate hike expectations, and the market is now pricing in less than one full rate hike by December. They also pointed out that long-end Treasury yields remain elevated, which some commentators attribute to "credibility concerns."

On the geopolitical front, the stalemate in U.S.-Iran talks persists. Iran's Foreign Minister Abbas Araghchi stated that no negotiations are currently happening between Tehran and Washington, adding that the U.S. must agree to Iran's conditions for shipping through the Strait of Hormuz to resume. This suggests that tensions in the Middle East are unlikely to ease in the near term, keeping the risk of energy supply disruptions alive. However, the safe-haven boost for the dollar from this risk appears limited. Strategists at Scotiabank observed that the dollar's brief bounce following the CPI data "has quickly run out of steam," stalling after the PPI release, and the market is "again leaning heavily into dollar shorts." They believe this renewed bearish sentiment reflects growing investor conviction that the Fed is unlikely to tighten policy again soon.

Kit Juckes, Chief FX Strategist at Societe Generale, noted in an August report that the dollar may trade in a range over the summer but is relatively bullish looking toward year-end, forecasting the DXY to be about 4% higher than current levels. Over the long term, the dollar faces pressure from potential slowing U.S. growth and improving European economies. He added that the current dollar level is broadly consistent with priced-in rate expectations (one Fed hike), making it neutral in the short term, and crowded positions could make the path choppy. While interest rate differentials and fundamentals support a stronger dollar into year-end, the narrowing growth gap will be a headwind over a longer timeframe.

State Street Global Advisors, in its August currency commentary, stated that the dollar has softened, creating selective opportunities in G10 currencies. However, the resilience of the U.S. economy, high yields, and geopolitical uncertainty mean it's too early to declare a sustained bear market. The dollar entered August facing headwinds from weaker-than-expected jobs, inflation, and Q2 GDP data, along with a dovish-leaning July FOMC meeting. Yet, strong domestic final demand, low unemployment, leading G10 yields, and Iran-related risks provide support. They suggest only tactical short positions unless employment and inflation weaken significantly further. The firm maintains a medium-to-long-term bearish view on the dollar due to fiscal deficits, current account issues, and policy risks, but believes the risk of a sustained bear market is not imminent.

In summary, the dollar index's continued weakness to the 99.50 level is primarily driven by a broad-based softening of U.S. economic data. The surprise drop in retail sales, combined with cooling CPI and PPI, has pushed the probability of a September rate hike down to 33%. While the U.S.-Iran negotiation impasse offers some safe-haven support, it has not been enough to shift the dollar's bearish momentum, with Scotiabank noting the market is again leaning heavily into dollar shorts. Should upcoming U.S. data weaken further, the dollar index could break below the 99 mark. Conversely, a significant escalation in geopolitical risks or a surprise upside in U.S. data could trigger a short-covering bounce for the dollar.
