Glossary
Plain-language definitions for terms you'll encounter in geopolitics and international economics.
Article 5 (NATO)
The collective-defense clause of the North Atlantic Treaty: an armed attack against one ally is considered an attack against all. Invoked once in NATO's history, after the September 11, 2001 attacks on the United States.
BRICS
An informal grouping of large non-Western economies — originally Brazil, Russia, India, China, South Africa — expanded in 2024 to include the UAE, Iran, Egypt, and Ethiopia. The grouping coordinates on alternatives to G7-led institutions but lacks treaty structure.
Bilateral Investment Treaty (BIT)
A treaty between two states that protects investments made by nationals of one state in the territory of the other. BITs typically guarantee fair and equitable treatment, protection against unlawful expropriation, and the right to international arbitration of investor-state disputes (through ICSID, UNCITRAL, or ad-hoc tribunals). Approximately 3,000 BITs exist worldwide. The investor-state dispute settlement (ISDS) mechanism is controversial — supporters argue it provides necessary legal certainty for cross-border investment; critics argue it creates a parallel legal regime that favours capital over states' regulatory discretion. Recent treaty reforms (the new generation of EU agreements with the Investment Court System) attempt to address the ISDS critiques.
Bretton Woods 2.0
An informal label for the post-1971 international monetary system, in which the original Bretton Woods regime of fixed exchange rates tied to gold-convertible dollars was replaced by floating exchange rates with the US dollar as de facto reserve currency. Economists Michael Dooley, David Folkerts-Landau, and Peter Garber coined the Bretton Woods 2.0 term in 2003 to describe the post-2000 pattern in which East Asian central banks accumulated dollar reserves to manage their currencies against the dollar, effectively recreating a quasi-fixed exchange regime through reserve management rather than treaty. The Bretton Woods 2.0 framing helped explain how the US could sustain large current account deficits for decades — the deficit was being financed by surplus countries' reserve accumulation. The 2014-2024 erosion of this pattern, as China and other surplus economies diversified reserves, suggests Bretton Woods 2.0 is gradually unwinding without a clear successor regime.
Bretton Woods system
The international monetary order designed at the July 1944 conference in Bretton Woods, New Hampshire, and in force from 1946 until 15 August 1971. Member currencies were pegged to the US dollar within a narrow band; the dollar in turn was convertible into gold at $35 per ounce for foreign central banks. The IMF and the World Bank were created to backstop balance-of-payments deficits and finance post-war reconstruction. Barry Eichengreen, in *Globalizing Capital* (1996, revised editions through 2019), traces how the system worked while US gold reserves and dollar liabilities were in rough balance, and broke when persistent US current-account deficits made the gold convertibility commitment incredible. President Nixon closed the gold window on 15 August 1971, ending fixed parities by 1973. What replaced Bretton Woods was a hybrid: floating exchange rates among the major economies, the dollar still functioning as the dominant reserve and invoicing currency, and the IMF reoriented towards crisis lending rather than parity defence. The currency-regime articles on this site treat that post-1971 order as the live system, with Bretton Woods 2.0 as one informal label for it.
Chokepoint
A narrow maritime or land passage through which a high share of global trade or energy flows must transit. The Strait of Hormuz, Bab-el-Mandeb, Suez Canal, Malacca Strait, and Panama Canal are the primary maritime chokepoints; their disruption has outsized effects.
Comparable treatment principle
A core principle of the Paris Club's sovereign debt restructuring framework: a debtor government's restructuring offer to Paris Club creditors must be matched, in present-value terms, by the offers made to non-Paris-Club creditors (commercial bondholders, Chinese policy banks, bilateral lenders outside the club). The principle is designed to prevent free-riding — where one creditor group preserves its claim while others take haircuts. In practice, applying comparable treatment to Chinese policy-bank loans has been a structural friction in the G20 Common Framework restructurings of Zambia, Ghana, and other distressed African sovereigns. Chinese creditors prefer case-by-case bilateral negotiation; Paris Club creditors prefer collective application of the principle. The dispute is procedural in form, distributive in substance.
Containment doctrine
A strategy of constraining a rival power's expansion by sustained diplomatic, economic, and military pressure short of direct war. George Kennan, writing as 'X' in *Foreign Affairs* in July 1947, argued that Soviet power would expand wherever it met no firm resistance, and that a patient policy of 'long-term, vigilant containment' would eventually force the Soviet system to mellow or break under its own contradictions. The doctrine shaped four decades of US grand strategy through NATO, alliance networks in Asia, the Marshall Plan, and forward-deployed forces. Kennan himself spent much of the rest of his life arguing that containment had been militarised in ways he never intended. The framework returned in the 2010s applied to China — first as 'pivot' or 'rebalance' under Obama, then as overt strategic competition under Trump and Biden. The Quad, AUKUS, and the Indo-Pacific Economic Framework are best read as alliance architecture for a containment-adjacent posture, even when officials avoid the word. Indo-Pacific analyses on this site track that framing without endorsing it.
Correspondent banking
An arrangement where one bank (the respondent) holds an account at another bank (the correspondent) to access services in a market it doesn't directly operate in. Most cross-border payments rely on correspondent banking, which is why loss of correspondent access from major banks effectively excludes a country from global finance.
Current account
The broadest measure of a country's trade with the rest of the world — covering goods, services, primary income (e.g. investment returns), and secondary income (e.g. remittances). A current account surplus means a country exports more value than it imports.
Current account surplus
A positive balance on the broadest measure of a country's external transactions — exports of goods, services, and net investment income exceeding imports plus net transfers. China, Germany, Norway, and the Gulf petrostates have historically run large current account surpluses, accumulating foreign assets. The mirror image is the current account deficit, which the United States has run continuously since the late 1970s. Persistent surpluses imply persistent capital outflows; persistent deficits imply persistent capital inflows. The macroeconomic identity is mechanical — the savings-investment balance and the current account balance are two views of the same accounting.
Decoupling vs derisking
Two different policy framings for the same underlying problem: how to reduce strategic exposure to China without breaking the trade relationship that funds much of European industry. 'Decoupling' implies a broad commercial separation — fewer supply-chain ties, less investment in either direction, parallel technology stacks. 'Derisking' implies selective diversification in narrowly defined critical sectors (semiconductors, critical minerals, batteries, pharmaceutical inputs) while keeping the wider trade relationship intact. The European Commission, under Ursula von der Leyen, formally adopted 'derisking' in March 2023; Mark Leonard at the European Council on Foreign Relations and Sander Tordoir at the Centre for European Reform have written the clearest analyses of the gap between the EU and US positions. Washington tends to use 'derisking' rhetorically while pursuing policies — chip controls, FDI screening, outbound-investment restrictions — that look closer to decoupling in the technology perimeter. The distinction matters because the two framings imply very different industrial policy commitments and very different diplomatic costs. See the decoupling-vs-derisking and EU anti-coercion-instrument analyses on this site for the working definitions actually in use.
Dollar liquidity (as power)
In a financial crisis, banks and firms outside the United States still need dollars — to settle trade, to refinance dollar debt, to meet collateral calls. Only the Federal Reserve can create dollars without limit. Whoever controls access to that liquidity in a crisis exercises a form of power most observers miss until it is being used. Adam Tooze develops this reading at length in *Crashed* (2018), arguing that the Fed's 2008 and 2020 dollar swap lines to selected foreign central banks were the decisive interventions that kept the global financial system from fragmenting — and that the choice of which central banks got swap lines (the ECB, BoE, BoJ, SNB, and a small expanded group) and which did not was a strategic act, not a technical one. The swap-line geography maps closely onto the US security alliance system. The same liquidity architecture explains why extraterritorial sanctions bite: banks that lose dollar correspondent access cannot fund their books in a crunch. The sanctions analyses on this site treat this liquidity dimension as the binding constraint, not the SWIFT messaging layer.
Export controls
Regulations restricting the export of specific goods, software, or technical information for national-security or foreign-policy reasons. Modern export controls heavily target dual-use technology, especially advanced semiconductors and the equipment to make them.
Extraterritorial sanctions
Sanctions that apply to persons or transactions outside the imposing country's territory, typically by threatening to cut off access to the imposing country's financial system if foreign parties deal with a designated target. US secondary sanctions are the prototypical example.
G7
An informal grouping of seven advanced economies — the US, UK, Germany, France, Italy, Japan, and Canada — plus the European Union as a non-enumerated participant. The G7 holds annual leaders' summits and coordinates positions on macroeconomic, geopolitical, and trade issues.
Geoeconomics
Using economic tools — tariffs, sanctions, investment screening, subsidies, export controls — to pursue what used to be considered purely strategic goals. Edward Luttwak coined the term in a 1990 *National Interest* essay arguing that after the Cold War, economic instruments would replace military ones as the main currency of great-power competition. Robert Blackwill and Jennifer Harris developed the framework into a full doctrine in *War by Other Means* (2016), cataloguing how China, Russia, and the United States each use trade and finance for coercion. The post-2018 tariff wars, the post-2022 Russia sanctions architecture, the October 2022 US semiconductor export controls, and the EU's anti-coercion instrument are all geoeconomic moves. The category is broader than 'economic statecraft' because it includes defensive industrial policy — onshoring, friend-shoring, supply-chain diversification — alongside offensive measures. Critics, including Henry Farrell and Abraham Newman in their later work on 'weaponised interdependence', argue that Luttwak's original frame underweighted the structural choke-points — dollar-clearing, the SWIFT messaging layer, ASML lithography — that determine who can actually coerce whom. See the export-controls and sanctions analyses on this site for case studies.
Hegemonic stability theory
The argument that the world economy works best when one dominant state — a hegemon — is willing to underwrite open trade, lender-of-last-resort liquidity, and a stable reserve currency. Robert Gilpin developed the political-economy version of the theory in *War and Change in World Politics* (1981); Charles Kindleberger had earlier argued in *The World in Depression* (1973) that the inter-war collapse happened in part because Britain could no longer play the stabiliser role and the United States was not yet willing to. The theory predicts that as the hegemon's relative economic weight declines, its capacity to absorb shocks for the system also declines — and the system becomes more crisis-prone unless a successor or a coalition takes over the stabilising functions. Critics, including Susan Strange and later Daniel Drezner, argue the theory overweights material capabilities and underweights the institutional and ideological work that goes into making rules stick. The framework is the analytical backdrop for current debates about whether the United States is still willing to play the role the post-1945 system was designed around — a question the *Chip War* and CHIPS Act analyses on this site both turn on.
Impossible trinity (trilemma)
A country cannot have all three at the same time: a fixed exchange rate, free movement of capital across its borders, and an independent monetary policy. It can have any two. Robert Mundell set out the underlying logic in 1963, and Maurice Obstfeld and Alan Taylor later formalised it as the policy 'trilemma' that every open economy faces. The classical gold standard chose fixed rates plus capital mobility, and gave up policy autonomy. The post-1971 floating regime gives up the fixed rate to keep policy independence with open capital accounts. China for decades chose policy autonomy plus a managed peg, and used capital controls to square the circle. The trilemma is one of the few genuinely ironclad results in international finance — every monetary regime is an answer to which of the three a country is willing to sacrifice. The dollar's reserve role and the local-currency settlement debate on this site both sit inside this frame.
MFN (Most-favored-nation) status
A WTO core principle requiring that any trade advantage one member grants to another (lower tariff, easier customs procedures, market access) must be extended to all other WTO members automatically. Permitted exceptions include free-trade areas and customs unions (GATT Article XXIV), preferential treatment for developing countries (the Enabling Clause), and national-security carve-outs (Article XXI). The 2022 US-EU coordination withdrawing MFN status from Russia in response to the Ukraine invasion was an unprecedented use of the Article XXI national-security exception applied multilaterally. The legal questions around what counts as a national-security justification under Article XXI are unresolved and likely to be tested further as state-on-state economic conflict intensifies.
Monroe Doctrine
A 19th-century US foreign policy stance, articulated in 1823, declaring opposition to European colonization or interference in the Western Hemisphere. Its modern legacy is shorthand for any great power claim to a regional sphere of influence.
Most-favored-nation (MFN)
A WTO principle requiring members to extend any trade advantage given to one country (e.g. a tariff reduction) to all other members. Exceptions exist for free-trade areas, customs unions, and developing-country preferences.
Neo-mercantilism
A new version of an old idea: that a country should run trade surpluses, build its own factories in important sectors, and back national champion firms. The updated version is shaped for global supply chains and high-tech rivalry. Dani Rodrik, in a series of papers from 2020 onwards, argues that the post-2008 retreat from hyperglobalisation has produced a new policy menu that includes explicit industrial policy, sectoral subsidies, local-content rules, public investment in research and development, and screening of foreign investment for security risk. Visible indicators include the US CHIPS Act and Inflation Reduction Act, the EU Chips Act and Green Deal Industrial Plan, Japan's Rapidus consortium, China's *Made in China 2025* and dual-circulation doctrine, and the post-2022 critical-minerals scrambles in Australia, Canada, and Indonesia. Rodrik separates 'productivist' industrial policy — investing in capabilities and good jobs — from 'mercantilist' policy aimed at trade surpluses or beggar-thy-neighbour gains. In practice, current policies blend the two. The CHIPS Act mid-term audit and the industrial-policy reshoring analyses on this site walk through which side of that line specific programmes sit on.
Petrodollar
Dollars earned by oil-exporting countries from their petroleum sales, typically recycled back into US Treasury securities, real estate, or other dollar assets. The arrangement underpinned dollar dominance for decades after the 1971 collapse of Bretton Woods.
Reserve currency
A currency held in significant quantities by central banks and treasuries to back their own currency, settle international debts, and intervene in foreign exchange markets. The US dollar is the dominant reserve currency; the euro, yen, and pound are also widely held.
Rules-based order (qualified)
A phrase Western governments use a lot. It refers to the system of treaties and institutions built after 1945 — the UN Charter, the WTO, the laws of war, freedom of the seas, the rules against the spread of nuclear weapons. The label is contested for three separate reasons that often get conflated. First, the rules in question were largely written by the victors of the Second World War and reflect their interests; many states in the Global South argue the order has always been selective in whose rules get enforced. Second, the United States itself has acted outside the rules when it has judged the stakes high enough — Kosovo without Security Council authorisation, Iraq in 2003, the US position on the International Criminal Court — which undercuts the moral framing. Third, as Amitav Acharya argues in *The End of American World Order* (2014, second edition 2018) and *Multiplex World* writing, the institutions and norms have always been shaped and reshaped by non-Western actors too, so the label 'rules-based order' obscures a more pluralistic history than the standard Western telling. The phrase still has analytical value when used carefully — for the specific bundle of post-1945 institutions and norms — and very little when used as a synonym for 'Western interests'. The Quad, AUKUS, and BRICS analyses on this site treat it as a contested label, not a neutral description.
SWIFT
The Society for Worldwide Interbank Financial Telecommunication — a messaging network used by banks to send payment instructions to each other. SWIFT does not move money itself; it transmits the messages that authorize money movement between banks.
Soft power
The ability to get other countries to want what you want, without paying them or threatening them. The pull comes from your culture, your institutions, and your foreign policy. Joseph Nye introduced the term in *Bound to Lead* (1990) and elaborated it in *Soft Power* (2004), arguing that the United States enjoyed a structural advantage because its universities, films, philanthropies, and political ideals had global reach. The framework had its high water mark in the 1990s and early 2000s. The 2020s have eaten the concept on three fronts: the Iraq war and its aftermath drained the legitimacy account; social-media fragmentation broke the unitary cultural signal Hollywood and American universities once carried; and rising powers — China's Confucius Institutes, Gulf state-funded universities, India's diaspora-based outreach — built their own soft-power infrastructure. Nye's later work concedes that hard and soft power are entangled in 'smart power', and that soft power without hard-power credibility behind it tends to evaporate when tested. The G7-G20 institutional-coordination analyses on this site treat soft power as one input among several, not the master variable the 1990s framing claimed.
Sovereign immunity
The doctrine in international law that a sovereign state cannot be sued in another state's courts without its consent. Modern practice distinguishes 'absolute' sovereign immunity (no suits permitted) from the 'restrictive' doctrine that most states now follow, under which commercial activity by states is subject to ordinary jurisdiction but sovereign acts (military, diplomatic, regulatory) are not. The US Foreign Sovereign Immunities Act of 1976 codifies the restrictive approach. Sovereign immunity is the legal architecture behind the practical fact that defaulting sovereigns cannot be forced to pay by court order alone — restructuring requires creditor coordination rather than judicial enforcement.
Strategic ambiguity
A deliberate policy of leaving unclear whether and how a state would respond to a specific event — most famously US policy on whether it would defend Taiwan from a Chinese invasion. The aim is to deter both attack (by leaving threat plausible) and adventurism (by leaving support uncertain).
