RBA Warns Australian Markets Face Geopolitical Shock Risk

Australian institutions need to prepare for a more shock-prone financial system as geopolitical tensions rewire global linkages, a senior Reserve Bank official said Wednesday.

RBA Assistant Governor Brad Jones used a speech in Melbourne to trace how the international order shapes financial stability – from the 1648 Peace of Westphalia to the post-war Bretton Woods system. After decades of relative calm following the Cold War, frictions between power blocs have returned, he said.

"All of this brings us to the old aphorism – we must take the world as it is, not as we wish it to be," Jones told a banking conference. "It is in this context that policy makers are dialing up efforts to ensure the financial system can weather a more challenging risk environment."

The warning lands just before the U.S. and Iran are expected to sign an interim deal Friday, ending a war that sent oil prices surging and threatened a wave of inflation. Earlier trade conflicts already upended supply chains and raised costs for companies sourcing goods across borders. Any fresh disruption would hit a system Jones described as more interconnected – and more fragile – than in past decades.

He pointed directly at Australia's vulnerability. Roughly half the nation's fixed-income market is held by foreign investors, meaning shocks from abroad transmit quickly into local bond yields. And "around half of the assets of our super fund industry are invested offshore," Jones said, referring to the pension sector. A disruption to cross-border capital flows would hit both bond prices and retirement savings simultaneously.

The transmission path for traders runs through the Australian dollar and bond yields. If the Iran deal fails or new frictions emerge, the AUD could drop as risk appetite contracts, while yields may spike on foreign outflows. Gold and crude oil would be the first cross-asset movers – oil because of the direct Iran link, gold as a hedge against systemic uncertainty.

Jones did not name which specific shocks the RBA sees as most likely. His historical framing – from Westphalia to Bretton Woods – suggested the central bank is thinking in decades, not quarters. The message for institutions: plan for a world where the old certainties about open markets and stable capital flows no longer hold.

Friday's U.S.-Iran signing is the first real test. If it proceeds smoothly, markets may treat the speech as background noise. If it stalls, Jones's warning starts looking prescient – and the Australian dollar becomes the front line.
