When Stability Becomes Strategy: Economic Security, Financial Power, and the Psychology of Global Order

The New Politics of Stability

Economic security used to sound like a technocratic phrase, the kind of language found in central-bank minutes and trade communiqués. Today it sits much closer to the center of geopolitics. The OECD now defines economic security as a nation’s ability to protect economic stability and growth by strengthening resilience against internal and external threats, and it explicitly links that idea to access to energy, food, technology, infrastructure, and trade and investment flows. [1] [2]

That shift matters because the institutions that were built after the Second World War were designed to make prosperity boring and therefore peace more durable. In July 1944, delegates from forty-four nations met at Bretton Woods to create a new monetary order, establish the IMF and what became the World Bank, and avoid the destructive mix of competitive devaluations and restrictive trade policies that had worsened the interwar collapse. [3] [4]

The paradox is that the same dense networks that once promised stability now create leverage. A payments system can become a chokepoint. A reserve currency can become a strategic asset. A tariff can be less about revenue than about expectations. And markets react not only to actual losses, but to the fear of what might become unfinanceable, uninsurable, or politically untouchable. The WTO warned in April 2025 that, under current conditions, world merchandise trade was expected to fall by 0.2% in 2025, with a worse scenario of a 1.5% decline if policy deterioration continued. [5] [6]

The deeper story, then, is not just about sanctions, tariffs, or market volatility. It is about whether the global economy can still function as a peace architecture when stability itself has become a strategic weapon.

Peace Has a Material Infrastructure

One of the least sentimental but most important ideas in international affairs is that peace depends on systems. It depends on shipping routes, reserve assets, credit channels, legal predictability, and the everyday expectation that tomorrow’s transactions will still clear. The postwar order was built around that assumption: durable peace required more than treaties; it required institutions that reduced panic and made economic breakdown less likely. Bretton Woods was explicitly a response to the failures of the interwar period, when monetary disorder and trade restriction helped intensify the global slump. [7] [8]

That intuition has never been entirely naïve. Research in political economy has long argued that the gains from trade can raise the cost of conflict. In a widely cited IZA discussion paper, Solomon Polachek argues that higher gains from trade between two countries lower the level of bilateral conflict because conflict destroys those gains. [9] [10]

The historical record is harsher than the theory. A World Bank paper notes that a civil war costs the average developing country roughly thirty years of GDP growth and that trade can take twenty years to return to pre-war levels. [11] [12] This is the part that is easy to miss in abstract debates about “resilience”: once security collapses, the repair bill is not only military or political. It is commercial, financial, and generational.

So economic security is not simply a nationalist reflex or a fashionable umbrella term. At its best, it is an old lesson restated in modern language: if societies cannot rely on energy, food, payments, credit, and trade, they do not remain calm for long. The peace dividend has always rested on material confidence, not on idealism alone.

The Postwar Bet

The original postwar wager was not that commerce would eliminate power politics, but that it would raise the cost of chaos. That is why institutions such as the IMF and World Bank were created before the age of high-frequency trading or supply-chain software: policymakers already understood that economic disorder is rarely just economic. [13] [14]

Finance Is Both Safety Net and Battlefield

If trade is the circulatory system of the global economy, finance is its nervous system. It transmits trust quickly, and panic even faster. That is why financial stability and geopolitical stability are now impossible to keep neatly separate. The 2008–09 crisis showed how a financial rupture can become a geopolitical event in everything but name: the WTO reported that the volume of world trade fell by 12% in 2009, a contraction larger than economists had expected and unmatched by any other decline since 1965. [15] [16]

More recently, the invasion of Ukraine demonstrated the opposite dynamic: geopolitics can weaponize finance directly. The ECB notes that, after Russia’s invasion, sanctions included the freezing of nearly half of the Russian central bank’s foreign-exchange reserves and the exclusion of some Russian banks from SWIFT, the dominant financial messaging system for cross-border payments. [17] [18] Brookings reports that the stock of frozen Russian sovereign reserves has been estimated at roughly $280 billion, with many experts placing the figure between $300 billion and $330 billion. [19] [20]

This is where the language of “weaponized interdependence” becomes useful. Farrell and Newman argued that institutions built to generate efficiencies and lower transaction costs can also be deployed for coercive ends, turning focal points of cooperation into sites of control. [21] [22] The global economy does not stop being integrated when conflict rises; instead, integration itself becomes usable terrain.

Yet there is a second paradox. Even after the Russia shock, the monetary order has shown more inertia than some commentators expected. IMF COFER data for 2025Q4 still showed the U.S. dollar at 56.77% of disclosed global reserves and the euro at 20.25%, while the renminbi was just 1.95%. [23] [24] ECB and IMF staff also found that the dollar and euro together still accounted for more than 80% of global trade invoicing. [25] [26] The system is weaponizable, but it remains hard to replace.

The Chokepoint Problem

That difficulty of exit is precisely what gives network power its bite. Brookings describes weaponized interdependence as the ability of states controlling central nodes to gather information, block flows, and compel change, which is why payment rails, custody systems, and reserve currencies matter far beyond finance ministries. [27]

Markets Price Fear Before They Price Damage

Markets do not wait for full information. They trade on probabilities, analogies, and the speed with which bad narratives can become funding stress. That is why risk perception has become one of the most underrated variables in global stability. The Federal Reserve’s geopolitical risk research, based on newspaper records since 1985, finds that higher geopolitical risk depresses economic activity, lowers stock returns, and causes capital to flow from emerging economies toward advanced ones. [28] [29]

The ECB makes the mechanism explicit: adverse geopolitical events can trigger rapid shifts in market sentiment, sharp increases in uncertainty, and negative effects on funding, lending, solvency, asset quality, and profitability across both banks and non-banks. [30] [31] The same ECB analysis also warns that such events may not cause a systemic crisis on their own, but they can trigger one when they interact with pre-existing vulnerabilities. [32] [33]

That interaction effect is crucial. In January 2026, the ECB and ESRB reported that, in response to geopolitical shocks, banks and non-banks reduce lending, especially cross-border exposures; the adjustment lowers exposure to external shocks but also reduces international diversification. [34] [35] What looks prudent at the firm level can quietly fragment the system as a whole.

And still, confidence does not disappear evenly. The Bank of England’s 2026 H1 Systemic Risk Survey found that respondents remained confident in the stability of the UK financial system even as geopolitical risk and cyberattack were the two most frequently cited risks and the most likely to materialise. [36] [37] That is the psychological hinge of modern finance: the same actors can be worried and confident at the same time, provided they believe the backstops are credible.

Fear Travels Through Funding Markets

When confidence weakens, the damage often appears first in dollar funding. The Federal Reserve says its central-bank liquidity swap lines are designed to improve dollar funding conditions in the United States and abroad and to serve as a prudent liquidity backstop. [38] [39] An IMF note on the March 2020 shock found that swap-line announcements were associated with a narrowing of the cross-currency basis by about 80 basis points for swap-line currencies. [40] Markets do not just need capital; they need proof that somebody will stand behind the plumbing.

Psychological Warfare, Economic Competition, and the Case for Mindful Diplomacy

The most sophisticated forms of economic competition are rarely only about immediate material loss. They are about shaping beliefs. A sanction can tell banks that a jurisdiction has become compliance-heavy. A tariff can tell firms that a supply chain is politically insecure. A reserve freeze can tell central banks that “safe” assets are safe under conditions. That is why psychological warfare in economics is often conducted through perfectly legal instruments.

The global economy is increasingly vulnerable to this pressure because interdependence creates both efficiency and strategic exposure. OECD research warns that poorly designed economic-security measures can undermine the benefits of open markets even when the original goal is resilience. [41] [42] The IMF’s work on geoeconomic fragmentation makes the same point from another angle: fragmentation threatens losses to global living standards severe enough to be comparable to those seen during COVID-19. [43] [44] And the IMF’s broader staff discussion note argues that the costs of fragmentation run through trade, migration, capital flows, technology diffusion, and the provision of global public goods. [45] [46]

The phrase “mindful diplomacy” sounds soft, but the substance is hard-headed. It means calibrating pressure so that coercion does not become self-harming disorder. It means recognising that not every vulnerability should be turned into leverage, because overuse of leverage teaches the system to route around you. The ECB has already noted that some countries have explored alternatives to traditional currencies and payment systems, even if the broader international-currency structure has not yet dramatically shifted. [47] [48] Economic statecraft works best in the short run when it is credible, but it remains sustainable in the long run only when it is seen as bounded.

Restraint Is Part of Power

Two quiet examples matter here. In December 2022, the UN Security Council created a standing humanitarian carve-out across UN sanctions regimes, and OFAC said the carve-out was meant to enable legitimate humanitarian assistance while still denying resources to malicious actors. [49] [50] In February 2024, the EU introduced a further humanitarian exception to sanctions, explicitly stating that sanctions should not obstruct the delivery of assistance or other activities supporting basic human needs. [51] [52] The point is larger than aid: durable economic power requires visible limits, because trust is part of the instrument.

The Peace Function of a Credible Economy

The central tension in the global economy is no longer whether states will pursue security through economic means. They already do. The real question is whether they can do so without dissolving the cooperative foundations that made economic stability a pillar of peace in the first place. The postwar order was built on a sober idea: confidence, convertibility, and commerce could make conflict costlier and collapse less contagious. [53] [54]

What has changed is that these same systems now carry coercive power. Payments networks can punish. Reserve assets can be politicised. Market sentiment can transmit strategic fear long before actual shortages appear. But the answer is not nostalgia for a depoliticised economy that never fully existed. It is better design: stronger backstops, clearer carve-outs, narrower use of coercive tools, and more disciplined diplomacy around the infrastructures that everyone depends on. The more interconnected the world remains, the more peace will depend not just on wealth, but on the credible management of shared vulnerability.
