Despite a confluence of favorable conditions that are typically Dollar bullish — a decidedly hawkish Federal Reserve, plummeting stocks, and soaring yields — the greenback's response was unexpectedly tepid last week. While it managed to gain ground against European majors and Yen, it faltered when squared against the robust commodity currencies. Dollar Index, a measure of the currency against a basket of other major currencies, also recorded only a modest uptick. With the quarter's end on the horizon, it's plausible that a sense of caution may have restrained Dollar's potential surge. Alternatively, traders might possibly be awaiting further developments to validate a one-sided bullish shift.
