US dollar firms on risk aversion, but DXY risks break below key 100.5 support

The US dollar was broadly firmer as risk aversion dominated, with equities weaker and oil higher. The US Dollar Index (DXY) drift from late-June highs paused at support around 100.5, even as weak inflation data shaped trading through the week. Bonds were mostly firmer across core markets, and Treasurys modestly outperformed.

Late-week price action was more supportive for the dollar, yet DXY still faced the prospect of a bearish weekly close unless it rallied further before the session ended. Concerns centred on the tech and chip cycle alongside escalating US/Iran attacks, feeding the risk-off tone across markets. Overnight index swaps (OIS) continued to imply a Federal Reserve hike by year-end, and that pricing was described as too rich; a repricing of the swaps curve was framed as a potential source of USD downside.

Bearish Outlook for the US Dollar and Trading Strategies

We advise derivative traders to position for a weaker US Dollar in the coming weeks as the US Dollar Index (DXY) struggles to hold its critical 100.5 support level. Although safe-haven flows from rising geopolitical tensions have temporarily propped up the greenback, the broader technical outlook remains heavily bearish. Selling DXY rallies or buying put options on the dollar appears to be the most profitable strategy right now.

Divergence in Rate Expectations and Structural Risks

We see a major discrepancy in the market, as Overnight Index Swap (OIS) pricing currently implies a high probability of a Federal Reserve rate hike by the end of the year. However, with recent US inflation data cooling to a year-over-year rate of 2.6%, further rate hikes are highly unlikely. As the swaps curve reprices to align with a pausing Fed, the dollar is bound to lose its yield support and fall.

While the current drop in global equities and rising oil prices have sparked a classic “risk-off” move, we expect this dollar support to be short-lived. Historically, failing to sustain a rally during risk-off periods indicates underlying structural weakness for a currency. Traders should exploit this by establishing short USD positions against stronger core majors, anticipating a break below the 100.5 floor.
