Dollar Index Rises 2% in September, Logging V-Shaped Rebound

The dollar's September rebound from early-month lows is notable because it reverses part of the prior weakness without confirming a broader trend shift: the quarterly gain is marginal, and the Bloomberg index actually slipped over the same three months. That divergence between monthly strength and quarterly flatness matters for dollar-sensitive assets, including commodities and crypto, which often trade against dollar direction. The open question is whether this V-shaped move extends into a sustained bid or fades as the quarter's rangebound pattern reasserts itself.
