Bourse slumps in 'horror show'

By the Editorial Team · Wednesday, September 16, 2026

The Australian Securities Exchange's ASX 200 index dropped to an 11-week low, falling 0.88 percent amid worries about rising interest rates and increasing oil prices. This decline reflects broader investor anxiety driven by expected central bank rate hikes and geopolitical tensions impacting commodity supplies, with major miners and banks particularly affected.

The Australian Securities Exchange experienced significant declines on Tuesday, with the ASX 200 index falling to an 11-week low amid concerns over rising interest rates and higher oil prices. The benchmark index dropped 77.4 points, or 0.88 percent, closing at 8,672.5. The broader All Ordinaries index also declined 74.6 points, or 0.84 percent, to 8,849.3.

The Australian dollar weakened against the U.S. dollar, slipping to 71.9 U.S. cents. Market sentiment was subdued across sectors, with six of the 11 sectors ending the day in negative territory.

Major miners faced notable losses, with BHP shares falling 2.21 percent to $59.25 and Rio Tinto declining 2.2 percent to $164.50. Fortescue Metals Group dropped 1.88 percent, closing at $16.22. Australia's leading banks also posted declines. Commonwealth Bank shares decreased 1.59 percent to $152.50, National Australia Bank fell 1.29 percent to $38.22, Westpac slipped 0.52 percent to $34.35, and ANZ was down 1.12 percent to $37.12.

Conversely, healthcare stocks provided some relief to the market. Vaccines manufacturer CSL rose 1.57 percent to $174.26. Medical equipment firms ResMed and Sonic Healthcare gained 2.85 percent and 1.57 percent, respectively, closing at $31.37 and $19.35.

The downward pressure on the market coincided with Brent crude futures climbing above $107 a barrel, driven by ongoing geopolitical tensions affecting the Strait of Hormuz and the Red Sea. The supply risks have further fueled concerns over rising commodity prices.

Analysts pointed to the increasing likelihood of interest rate hikes as a key factor depressing investor confidence. Tony Sycamore, senior market analyst at IG, described the trading day as a continuation of a “horror show” for the ASX 200, which followed a sharp decline of 264 points in the previous week. He noted the index has fallen 4.5 percent so far in September.

Sycamore highlighted that the U.S. 10-year Treasury yield had risen above 5.02 percent in Asia, reaching its highest level since 2007. This development occurs ahead of anticipated interest rate decisions by the Federal Reserve and the Bank of Japan later in the week. Along with the recent European Central Bank rate hike, these moves signal a broadening tightening cycle expected to prompt multiple rate increases by major central banks in the coming months.

In company-specific news, Nickel Industries shares plummeted 11.26 percent to $0.78 after the company warned that unexpectedly dry conditions in Central Sulawesi, Indonesia, have severely restricted water supply to its operations, potentially reducing output by 30 percent.
