New World Order, Part IV: The Petrodollar, and What Is Downstream

Introduction: Where the Three Rewrites Meet

The first three parts of this series traced three rewrites in parallel. Security is becoming a patchwork of regional balances rather than a single underwritten umbrella. The financial plumbing is being matched by parallel rails that have made bypassing the dollar cheap enough to be routine. The energy map is being redrawn along non-Western axes, with the next-generation supply chains concentrated in places the West does not control.

Each of those rewrites is significant on its own. What makes them historically interesting is that they reinforce each other. A regional security order that no longer defers to one underwriter has more reason to build parallel financial rails. A financial system with parallel rails makes it cheaper to settle energy trades outside the dollar. Energy trades settled outside the dollar erode the financial premium that funded the security umbrella in the first place. The three loops feed each other.

The petrodollar is the place where all three converge. Part IV closes the series at that keystone, then steps back to what it means for the institutions, the actors, and the people downstream of them.

The four parts of the series:

• Part I: Security: How the unipolar security umbrella is being replaced by overlapping regional balances.
• Part II: Financial: How parallel payment rails and reserve diversification are ending the dollar's monopoly on cross-border plumbing.
• Part III: Energy: How OPEC, pipelines, nuclear cooperation, and the energy transition are being redrawn along non-Western axes.
• Part IV: The Petrodollar, and What Is Downstream: The keystone case where security, finance, and energy converge.

The Petrodollar as Keystone

The petrodollar arrangement was never a single document. It was a set of mutually reinforcing practices: oil priced in dollars, oil revenues recycled into dollar assets (most prominently US Treasuries), security guarantees from the United States to the major producers that underwrote the arrangement, and a global market structured around dollar settlement as the default. The pieces emerged out of the 1970s and have shaped fifty years of global capital flows.

The arrangement is not gone. The majority of internationally traded oil is still priced and settled in dollars. The largest oil exporters still hold the bulk of their reserves in dollar assets. The US is still the most important security partner of the largest Gulf producers. The keystone has not been removed.

But the keystone has been loosened.

• Oil priced in non-dollar settlement is no longer a curiosity. Saudi-China barrel flows include yuan-denominated tranches. Russia-India crude moves in rupee-ruble structures. The UAE prices and settles a growing share of its energy and non-energy trade with Asian partners outside the dollar. None of these is a majority share. All of them were rounding errors five years ago.
• Recycling has diversified. Petrodollars used to flow predictably into US Treasuries and US assets. They now flow into infrastructure stakes across Asia, Africa, and Latin America, into Chinese and Indian growth equity, into AI infrastructure and defense industrial assets in the West, and into gold. The pool is still enormous and a large share still ends up in dollar assets. The reflexive default is gone.
• The security half of the bargain is no longer assumed. Part I argued that US security guarantees are now discounted by the political season. That discount applies as much in Riyadh and Abu Dhabi as it does in Tokyo and Warsaw. Hedging the security side is now part of how producer states think about the financial side.

The petrodollar is the keystone because, when you tug at it, you feel all three rewrites at once. Security guarantees, financial settlement, and energy pricing are the same arrangement looked at from three angles. The fact that all three angles are visibly shifting in the same direction is what makes the rewrite real.

The dollar's pricing dominance is not uniform. It is near-total in the Americas, fragmented in Europe, dominant but contested in Asia-Pacific, and dominant in the rest of the world for now. The interesting movement in 2026 is in the Asia-Pacific column.

"The petrodollar's significance was never just in oil. It was in how oil revenues recycled into one financial system. The recycling has diversified. The implications have not yet been priced into the policy assumptions of the major Western capitals." - Senior fellow, Atlantic Council

Trump-Xi: The Substance Is Now Bilateral

The Trump-Xi visit was the year's clearest demonstration of how great-power management actually works in 2026, and how little of it now runs through the multilateral institutions that were built to host it.

The visit was choreographed, dense with substance, and bilateral in a way that earlier US-China summits often were not. Trade terms, technology controls, currency understandings, defense de-escalation arrangements, energy and critical-minerals supply commitments - the work was done in the room between the two principals and their teams, and the outcomes were announced in joint statements rather than at the WTO, the UN, or the IMF.

A few features of the visit are worth naming as a pattern, not as a single event:

• The two-power format absorbs the substance. The questions that used to be negotiated in twenty-country forums are now negotiated in two-country meetings, with smaller forums used to communicate the outcome to the rest of the world.
• The deliverables are concrete and conditional. Earlier era summits produced communiques. The current era produces specific exchanges: this much access for that much restraint, this much technology for that much market opening, this much energy supply for that much security signaling. The contracts are tighter and the time horizons shorter.
• The institutions are informed, not consulted. The WTO, the IMF, the UN system - they receive readouts. They do not host the negotiations.

This is not a Trump-era anomaly. The bilateral G2 dynamic between the US and China has been building for fifteen years. What has changed is that it has stopped pretending to defer to the multilateral system. The two countries that matter most for the global economic and security order are now negotiating directly and acknowledging that they are doing so.

The Institutions Remain, Their Function Changes

The UN, the WTO, the IMF, the World Bank, the BIS, and the rest of the post-1945 institutional layer are not going away. They still meet. They still publish. They still play roles. But the role they play in 2026 is different from the role they were built for.

• The UN is increasingly theater. The General Assembly is a venue for signaling. The Security Council is paralyzed on the questions that matter most. The agencies that actually do work (UNHCR, WFP, IAEA) continue to deliver, but they operate as service providers within a political vacuum, not as instruments of a coherent international consensus.
• The WTO is in slow drift. The dispute settlement mechanism has been functionally weakened for years. Major trade questions are now resolved through bilateral or plurilateral arrangements (IPEF, CPTPP, RCEP, the EU's bilateral free trade agreements) rather than through the WTO framework. The institution is still useful for technical work and dispute adjudication where political stakes are low, but the marquee decisions happen elsewhere.
• The IMF and World Bank still matter for crisis lending and development finance, but they are no longer the only games in town. The AIIB, the New Development Bank, the Chinese policy banks, and the larger Gulf and Asian sovereign funds all provide alternatives. Conditionality is now negotiable.
• The BIS retains a quiet but important role in the technical layer of cross-border finance, including in the multi-CBDC work mentioned in Part II. This is one institution where the post-1945 architecture is still doing real work and is not yet bypassed.

The pattern is not collapse. The pattern is drift into a different role. The institutions remain useful for legitimacy, technical coordination, and signaling. They are increasingly bypassed for substantive decision-making.

"The post-1945 institutional architecture is not being dismantled. It is being repurposed. The hard work of coordination is moving to bilateral and plurilateral venues, and the institutions are being asked to legitimise outcomes they no longer shape." - Director, Chatham House

What Is Downstream

The job of the closing post is to translate the diagnosis into something usable. Across capital, supply chains, corporate strategy, and individual positioning, the same logic applies: read the new arrangement accurately, do not bet on the old one returning, and do not assume the new one is more settled than it actually is.

A few specifics:

• Capital allocation. Diversification away from a single-currency, single-jurisdiction default is now a normal portfolio behavior rather than a political statement. Reserve diversification by central banks, sovereign wealth deployment, and large-pool private capital are all running the same playbook: keep dollar exposure dominant, build optionality in adjacent currencies and assets, treat gold and adjacent stores of value as a structural allocation rather than a tactical one. Sanctions and asset-freeze risk are now a line item in long-term planning.
• Supply chains. Friend-shoring is the new floor. Single-source supply for critical inputs is increasingly treated as a strategic vulnerability rather than a cost optimization. The hardest cases are the ones where the friend-shored alternative does not yet exist at scale: critical minerals processing, advanced lithography, certain pharmaceutical inputs. The structural response is investment, but the time horizons are decade-plus.
• Corporate strategy. Operating across blocs that no longer share a single rulebook is now the default mode for any multinational. Compliance regimes are diverging, data and AI governance is fragmenting, and the cost of doing business across the US-China line keeps rising. The companies that handle this best treat regulatory and political environments as a first-class input to strategy rather than a back-office function.
• Individuals. The default assumption of dollar denomination, US-dominated equity exposure, and US-anchored career capital is no longer the only sensible posture. It is still a strong posture - the dollar is still the deepest currency, US capital markets are still the deepest pools, US labor markets are still among the most dynamic - but the tail risks on each are higher than they were. Geographic optionality, currency diversification, and skills that travel across regulatory regimes are all worth more than they used to be.

What This Means

The series began with a thesis: the post-1945 order is being rewritten, not collapsing. Across security, finance, energy, and now institutions, the same shape has appeared. The old arrangement still exists. It is still the largest single arrangement in the world. But it is no longer the only one, and the cost of operating outside it has fallen far enough that doing so is now routine.

A few final observations are worth making explicit:

First, the new order is not yet stable. The patchwork of regional balances, parallel financial rails, and bilateral great-power management is messier than what it is replacing. It is more honest about who has capability where, but it is also more contingent on the political season in any given capital. A more honest order is not necessarily a more peaceful one.

Second, the rewrite is uneven. Some pieces are moving fast (parallel payment rails, bilateral energy deals). Others are moving slowly (reserve composition, institutional decay). The temptation is to project the fastest-moving piece forward and assume the rest will follow at the same pace. The history of these transitions suggests they unfold over decades, not years.

Third, the West is not absent from the rewrite, it is participating in it. The US is rebuilding its industrial base, restructuring its alliance commitments, and rewriting its own rules on trade and technology. Europe is choosing resilience over efficiency. The story is not that the West has disappeared from the table. The story is that the table has more chairs, and the chairs are no longer arranged the same way.

The order is being rewritten. The job is to read it accurately, not to mourn the old one or pretend the new one is already here.

That is the whole series.
