ASX gold shares have tumbled since the war in Iran began, with the gold price slumping to nearly US$4,300 per ounce today.
The S&P/ASX All Ords Gold Index (ASX: XGD) has fallen 31% since 28 February, when Israel and the US launched strikes on Iran.
By comparison, the S&P/ASX All Ords Index (ASX: XAO) has fallen nearly 9% amid investors worrying about higher oil and gas prices.
The gold price is now down 13.2% over the past week and down 15.8% over 30 days as the Middle East conflict continues.
For now, concern about a potential resurgence in inflation has overridden gold's traditional safe-haven appeal.
Analysts from Trading Economics explain:
Gold had dropped as much as 25% from its March peak as rising energy prices fueled inflation concerns and bolstered expectations of interest rate hikes.
In a blog, Zaner Precious Metals said the Iran conflict had triggered broad market deleveraging and a stronger US dollar.
This has pushed US Treasury bond yields close to a 10-month high, weakening the appeal of non-yielding precious metals like gold.
Zaner said markets are tilted toward a 'risk-off' temperament, commenting:
That risk aversion is underpinning the dollar, as the trade seeks maximum liquidity.
