Australia should establish a unit dedicated to financial warfare capabilities

In an age of great-power competition, the next major conflict may be waged not in the skies over the Indo-Pacific or in the South China Sea, but through sanctions regimes, targeted financial disruptions and coercive use of trade and capital. Finance has emerged as a sixth domain of warfare.
Economic and financial warfare has become a critical instrument of statecraft, from Iran’s isolation from SWIFT to China’s creation of the Cross-border Interbank Payment System (CIPS). The ability to shape behaviour through financial tools is now a strategic reality. Australia, as a middle power with limited kinetic mass but outsized regulatory and technological clout, must take financial warfare seriously.
Australia’s deterrence measures lie in asymmetric capabilities. Just as cyber and space reshaped operational planning, Canberra can use financial tools to shape adversary behaviour, impose costs and support allies in the grey zone.
Our economic integration with the Indo-Pacific makes us both influential and vulnerable. Australia is deeply embedded in global financial networks and supply chains, with extensive dependencies in sectors like semiconductors, pharmaceuticals and critical minerals. The regulatory reputation of institutions such as AUSTRAC and the Reserve Bank gives Australia credibility, and our intelligence partnerships provide a deep well of financial data. These interconnections create leverage, but also exposure.
Australia should properly mobilise these assets to become a leader in economic and financial statecraft among middle powers offering asymmetric capability to our arsenal. The combined effort would also help to protect our financial vulnerabilities.
From an AUKUS perspective, our institutional architecture has not kept pace. Australia lacks a coherent entity capable of wielding financial power with precision and purpose, like the US Treasury’s Office of Foreign Assets Control or the wartime Ministry of Economic Warfare in Britain. This must change.
Warfare has always been about economics, since Athens and Sparta blockaded each other’s trade routes and the British disrupted Axis supply chains through economic subversion. More recently, US sanctions reduced Iranian oil exports from 2.7 million to under 500,000 barrels per day. These economic tools degraded adversary capacity without firing a shot.
But today, financial intelligence, market manipulation, sanctions enforcement, and cyberattacks on financial infrastructure converge as multidomain tools in warfare. China’s efforts to control rare earths, buy foreign ports and develop a digital yuan are coherent strategies of financial statecraft.
Financial warfare encompasses a wide spectrum of instruments, often deployed in synchronised campaigns to shape the strategic environment before the first shot is fired:
—Sanctions and export controls have constrained Iran’s oil exports and Russia’s defense industrial base.
—Asset freezes and Magnitsky-style laws target kleptocrats and human rights violators, disrupting elite networks.
—Cyber-financial attacks, such as North Korea’s 2016 Bangladesh Bank heist, illustrate the intersection of hacking and financial disruption.
—Currency manipulation and trade coercion, notably by China, undermine fair competition and weaponise market access.
—Supply chain domination, especially in critical minerals, allows adversaries to impose latent costs or influence decision-making through chokepoints.
To develop our own strategies of financial warfare, Australia should establish a Financial Warfare Office. Whether embedded within the Joint Capabilities Group or established as a standalone body reporting to the National Security Committee, its mission must be unambiguous: to use finance to deter aggression, degrade coercion and defend sovereignty.
Core capabilities should include fusion of financial intelligence, in which data is aggregated from AUSTRAC, the Australian Federal Police, private banks and allied intelligence to map financial vulnerabilities and illicit flows. Targeted economic instruments should be developed in collaboration with existing government entities to combine sanctions, investment restrictions and export controls. The dedicated unit should lead in resilience planning to identify weak points in critical financial infrastructure and supply chains. It should run strategic influence operations, leveraging financial narratives and market signals to amplify deterrence.
This unit would also serve as a key interface with AUKUS partners, particularly under Pillar Two, where financial, cyber and technological tools must be integrated for strategic effect.
For example, it could pre-emptively disrupt illicit financing of a hostile proxy group by tracing shell companies across Southeast Asia and triggering coordinated asset freezes with Five Eyes partners. It could also identify and block foreign acquisition of a biotech firm holding sensitive data, using regulatory levers to frustrate strategic land and IP grabs. Such risks are already recurring features of grey-zone competition.
Financial warfare is powerful but double-edged. Ill-considered sanctions can harm civilian populations, erode legitimacy and strain alliances. Cyber-financial campaigns may escalate unpredictably. Australia’s response must therefore be grounded in rule-of-law principles and transparent governance.
For this, we must invest in legal authorities, oversight frameworks and international coordination to ensure that economic tools serve democratic security, not undermine it. Financial warfare must not become a pretext for economic nationalism or short-term political gain.
Australia must now make economic and financial statecraft a core pillar of our national defense strategy. Doctrine, investment, institutions and alliances must be calibrated for this new domain of warfare.
