Rising Treasury Yields Pressure Gold and AUD/USD as Select Stocks Score Technical Breakouts

Rising U.S. Treasury yields dominated financial markets on Tuesday, September 15, sending gold to its lowest open in two weeks and intensifying pressure on the Australian dollar ahead of a Federal Reserve meeting that kicked off the same day. Gold December futures opened at $4,340.30 per troy ounce, down 0.3% from Monday's close, and slid further to $4,315.30 during early New York trading. The metal stalled below its 100-day simple moving average as higher yields lifted the cost of holding non-interest-bearing assets, a dynamic underscored by the inverse relationship gold typically holds with both the dollar and real rates.

The Australian dollar compounded its retreat from September highs, with momentum indicators weakening and the pair testing a key uptrend support level that traders flagged as critical ahead of Wednesday's session. AUD/USD had been trading near 0.72 in recent weeks after an extended uptrend, making the support test a potential inflection point for the pair's medium-term direction.

Against the broader pressure, a handful of individual names bucked the trend with notable technical breakouts. ResMed crossed above its 200-day moving average of $227.72, trading as high as $234.33 and gaining roughly 3.7% on the session. The KraneShares SSE STAR Market 50 Index ETF similarly cleared its 200-day average at $22.38, reaching $22.64 and rising about 1.5%. JPMorgan Chase shares also attracted bullish attention from market participants during the session.
