ASX 200 Falls 7.5% in March 2026: Is April a Recovery Opportunity or More Pain Ahead?

ASX 200 Sinks in March: What Comes Next in April?

The S&P/ASX 200 closed March at 8,501.80, down approximately 7.5% for the month and its worst monthly performance since June 2022. The index sits roughly 8% below its all-time high of 9,202 set in late February. Three forces drove the selloff: an energy shock from the US-Iran conflict, a heavy tech sector decline, and banks under mounting rate pressure. The All Ordinaries has lost approximately A$300 billion in value since the conflict began. For investors now sitting on losses, the question is a simple one. Is this a buying opportunity, or is there more pain to come?

What Actually Caused the March Crash

The US-Iran conflict is the root cause of everything playing out on the ASX right now. Brent crude closed March at US$118.31 per barrel, up nearly 5% on the final trading day alone, after US military strikes near Iran’s Kharg Island oil export hub raised fears of a prolonged supply disruption. Higher oil means higher inflation, and higher inflation means the Reserve Bank of Australia (RBA) may be forced to keep hiking rates, which is the last thing investors want to hear.

Technology stocks bore the brunt of the selloff. WiseTech Global fell 5.5%, and Xero dropped 4.7% in a single session, as rising bond yields reduced the present value of future earnings. Banks were also dragged lower, with Westpac falling 4.1% in a single session and CBA shedding 1.37% across March, weighed down by concerns over slowing credit growth and stressed household budgets. The one bright spot was energy stocks. Woodside Energy and Santos held up well as oil prices surged, while gold recovering toward approximately US$4,600 per ounce by the close of March gave gold miners a meaningful tailwind across the month. This sector rotation signals that investors are positioning for inflation, not growth.

The Case For Buying in April

History offers some comfort here. UBS examined 15 geopolitical shocks over the past 50 years and found the ASX 200 returned an average of 4%, 5%, and 11% over the following 3, 6, and 12 months, respectively. If the current conflict remains contained, the worst of the market reaction may already be priced in.

Encouragingly, today brought a material development. President Trump signalled he is willing to end the US military campaign against Iran even if the Strait of Hormuz remains largely closed. WTI crude pulled back from its session high to around US$102, and the ASX 200 staged a solid intraday recovery. This is the most significant positive catalyst of the month and changes the April outlook meaningfully.

There are already early signs of a rotation back into growth stocks. On the final trading day of March, WiseTech jumped 4.5%, and Xero surged 7.2% as investors began buying back into deeply oversold quality growth names. We believe these stocks are beginning to look attractive on a valuation basis after their sharp pullbacks, and further de-escalation in the Middle East could accelerate that recovery meaningfully.

The Case For More Pain in April

The risks should not be dismissed. Brent crude closed March at US$118.31 per barrel, still well above levels that are comfortable for Australian inflation. Morgan Stanley estimates that oil at US$100 per barrel alone adds approximately 70 basis points to headline inflation. With Australian inflation already running at 3.8%, above the RBA’s 2-3% target band, markets are pricing a back-to-back rate hike at above 70% probability, potentially lifting the cash rate to 4.10%. The OECD has separately warned that Australia could face one of the highest inflation rates among advanced economies. At current levels, we believe the ASX 200 is not yet fully pricing in a scenario where oil re-escalates and the RBA is forced into further hikes beyond May.

The Investor’s Takeaway

Our view is that April calls for selective buying rather than broad market exposure. The Trump de-escalation signal is genuinely encouraging and shifts the risk balance modestly in favour of buyers. Energy stocks and gold miners remain well-positioned as inflation hedges and are the sectors we would prioritise. Conversely, consumer discretionary names and highly rate-sensitive stocks carry the most downside risk if oil re-escalates.

For investors watching the data, three triggers matter most in April: the RBA’s next rate decision, the trajectory of Brent crude, and any further diplomatic signal from the Middle East. A sustained ceasefire would change the outlook quickly. Until there is clarity, stay disciplined, focus on quality, and use staggered buying rather than committing all at once.
