Energy Shock Drives Broad Market Sell-Off
Australian equities endured a bruising week, with the benchmark share market retreating sharply as inflation fears and a sudden surge in oil prices rattled investor sentiment across global markets.
The S&P/ASX 200 declined 2.64 percent for the week. Nearly every major sector finished lower.
Technology companies, healthcare stocks, real estate investment trusts and gold miners experienced the heaviest selling pressure as investors reduced exposure to growth oriented and rate sensitive assets.
Yet beneath the headline sell off, several pockets of resilience appeared. Banks managed to hold relatively steady. Energy stocks gained ground, supported by surging crude prices. Defence related technology names and infrastructure operators also attracted selective buying interest as investors rotated toward sectors with strong earnings visibility.
Currency markets and commodities reinforced the same message. Markets are increasingly pricing a potential stagflation scenario, where slower economic growth collides with rising input costs and renewed inflation pressure.
ASX Winners and Losers
The final trading session of the week provided a clear snapshot of where capital flowed as volatility increased.
Using the volume filtered data from FNArena’s daily movers list for 13 March, the divergence between defensive sectors and speculative names was evident.
Top ASX 300 Gainers
The strongest performers on the final trading day were concentrated in defence technology, infrastructure and specialised technology companies.
| Rank | Code | Company | Price (A$) | Daily Move |
|---|---|---|---|---|
| 1 | EOS | Electro Optic Systems Holdings | 11.74 | +18.35% |
| 2 | LIC | Lifestyle Communities | 5.31 | +17.22% |
| 3 | QOR | Qoria | 0.34 | +7.94% |
| 4 | DRO | DroneShield Limited | 4.17 | +6.38% |
| 5 | DBI | Dalrymple Bay Infrastructure | 4.93 | +6.02% |
The common theme was clear.
Defence related technologies and infrastructure assets attracted buyers despite the broader market weakness, highlighting investor demand for companies linked to long term government spending or essential assets.
Top ASX 300 Losers
Losses were more concentrated in resource stocks and biotechnology names, particularly those that had rallied strongly earlier in the year.
| Rank | Code | Company | Price (A$) | Daily Move |
|---|---|---|---|---|
| 1 | IMM | Immutep | 0.045 | -88.61% |
| 2 | NST | Northern Star Resources | 21.75 | -18.75% |
| 3 | IPX | IperionX | 5.26 | -14.05% |
| 4 | KAR | Karoon Energy | 1.84 | -7.07% |
| 5 | KCN | Kingsgate Consolidated | 6.12 | -6.28% |
The collapse in Immutep highlighted the volatility often seen in small cap biotechnology stocks following disappointing clinical updates.
Meanwhile, gold producers such as Northern Star experienced a sharp pullback after the sector’s strong rally earlier in the year.
Weekly Performance Across ASX Sectors
The selling pressure across the market was widespread.
Growth sectors and interest rate sensitive industries bore the brunt of the correction, while energy stocks stood out as the only sector posting gains.
| Index / Sector | Weekly Move |
|---|---|
| S&P/ASX 200 | -2.64% |
| All Ordinaries | -2.71% |
| S&P/ASX 300 | -2.71% |
| Information Technology | -6.99% |
| All Technology Index | -5.73% |
| Health Care | -4.64% |
| Materials | -4.73% |
| Gold Index | -9.71% |
| Real Estate | -5.04% |
| A-REITs | -4.96% |
| Consumer Discretionary | -2.07% |
| Consumer Staples | -2.69% |
| Energy | +1.72% |
| Financials | -0.37% |
Banks were one of the few areas showing relative resilience. Major lenders managed to post modest gains overall during the week, which helped prevent an even deeper decline in the broader index.
Commodities: Energy Shock Dominates Markets
Commodity markets delivered one of the clearest signals about the source of the recent volatility. Energy prices surged dramatically. Crude oil recorded one of its largest weekly moves in recent years as supply concerns intensified across global markets.
Oil Markets
West Texas Intermediate crude rose approximately 20.8 percent during the week, finishing near US$96 per barrel. Brent crude followed a similar trajectory, rising roughly 20.9 percent to around US$101 per barrel.
At certain points during the week, some contracts briefly traded above US$110. The rally reflects growing fears about supply disruptions in the Middle East combined with already tight global inventories.
Major investment banks have warned that if supply interruptions persist, oil prices could surge into the US$130 to US$150 range.
Such a scenario would create significant inflation pressure for global economies and potentially trigger further volatility in equity markets.
Metals and Precious Metals
Precious metals delivered mixed results. Gold finished the week broadly unchanged, declining just 0.14 percent while still remaining more than 15 percent higher for the year to date.
The gold equities sector experienced a much sharper correction. The ASX Gold Index fell nearly 10 percent during the week as investors locked in profits after the strong rally seen earlier in 2026.
Silver showed greater resilience, rising around 2 percent during the week. Industrial metals remained relatively stable. Copper finished almost unchanged, maintaining its reputation as a barometer of steady but not explosive global demand. Aluminium and zinc recorded stronger gains, while nickel slipped slightly. Iron ore also rose roughly 3.8 percent for the week, although prices remain lower than the start of the year.
Currency Markets Send a Risk-Off Signal
Foreign exchange markets reflected a classic shift toward defensive positioning. The US dollar strengthened as investors sought safe haven assets amid rising inflation concerns and geopolitical tensions. The US Dollar Index advanced during the week, supported by expectations that higher oil prices could delay potential interest rate cuts.
The Japanese yen also strengthened slightly. However, large interest rate differentials continue to weigh on the currency relative to the US dollar.
The Australian dollar weakened modestly. AUD/USD drifted back toward the low 0.70 range as global risk appetite softened and commodity markets remained volatile.
Currency strategists continue to monitor the 0.68 to 0.69 support range, which many analysts view as a critical technical level. For investors, the message is straightforward. The US dollar is regaining strength, while Australian dollar momentum may remain limited until energy markets stabilise and inflation pressures begin to ease.
Earnings and Events Watchlist
With the majority of February earnings results now released, attention is shifting toward corporate guidance updates, dividend events and sector specific catalysts.
Several companies could remain in focus next week.
| Company | Event | Why It Matters |
|---|---|---|
| Electro Optic Systems Holdings | Post rally consolidation | Defence technology demand continues to strengthen |
| Northern Star Resources | Sector sentiment | Investors watching whether gold equities stabilise |
| Karoon Energy | Oil price leverage | Surging crude prices may reshape earnings outlook |
| Cochlear Limited | Ex dividend trading | Healthcare sector remains under pressure |
| Major banks | Dividend cycle | Bank dividends remain key income drivers for the ASX |
The reaction of gold stocks following the recent correction may prove particularly important. If the sector stabilises, it could signal that broader resource equities are approaching a short term floor.
