The NZX 50 experienced a decline of 47 points, equating to a 0.4% drop, settling at 12,719 during the morning trading session on Monday. This decline paused the gains seen in the previous session, as the index mirrored the downturn in US stock futures. This downward trajectory occurred after President Donald Trump announced that the implementation of new tariffs would commence on August 1, rather than the initially slated date of July 9. Additionally, investor caution grew in anticipation of the Federal Reserve meeting minutes set to be released later this week, providing insight into the central bank's future policy direction. Domestically, the apprehension increased ahead of the Reserve Bank of New Zealand's upcoming monetary policy decision, with market forecasts predicting the central bank will maintain the interest rate at 3.25%. Most sectors saw a decline, notably consumer staples, healthcare, financials, and real estate. Early notable losses included Fletcher Building with a 2.0% decrease, Ryman Healthcare down by 1.7%, South Port New Zealand dropping 1.4%, A2 Milk falling by 1.1%, and ANZ Group dipping 0.5%. Meanwhile, Fisher & Paykel, Contact Energy, and Infratil each experienced a 0.6% decline.
