From Cádiz to Hormuz: What a Silver Crisis from 1805 Can Teach Us About Investing in 2026
The Trafalgar squeeze and its relevance to positioning post-Iran war, plus timely ideas that haven’t moved massively yet
An equity investing framework for the post-Hormuz energy sovereignty regime. The historical analysis draws on a May 2026 Bank for International Settlements (BIS) working paper by Bignon, Mojon, and Ortiz Serrano.
We start with a story…
Gabriel-Julien Ouvrard was thirty-five years old in 1805, and he had borrowed an enormous amount of money against ships he could not see.
The ships in question were Spanish galleons carrying silver from the mines of Mexico and Peru. Ouvrard, the son of a provincial paper merchant who had become one of the richest men in France by quietly supplying the navy during the Revolution, had built a financial structure around them. He and two partners, Médard Desprez and Ignace-Joseph Vanlerberghe, ran a firm called the Compagnie des Négociants Réunis (CNR), which translates with a kind of corporate plainness that would not be out of place in a modern pitch deck as “The Merged Merchants Company.” The economists at the BIS who later reconstructed the firm’s balance sheet would call it “arguably even greater than that of Lehman Brothers in the 2008 financial crisis.” That comparison is not a metaphor. It is structural.
Here is what the CNR did. Napoleon’s Treasury needed money to fight Britain. The Spanish Crown, which owed France a great deal of money, did not have any cash but did, theoretically, have access to enormous quantities of silver from its American colonies. Ouvrard negotiated to buy the future silver shipments at 3.75 francs per coin, knowing the same coins would be worth 5 francs once they reached Europe. To finance this arbitrage, he borrowed from everyone. He borrowed 10 million francs from Parisian banks. He borrowed 12 million florins from Hope & Co. in Amsterdam, the bluest of blue-chip lenders. He borrowed 100 million francs in credit from a Spanish institution called the Caja de la Consolidación, itself secured by discounted futures on the very same Spanish dollar coins. And, most consequentially, he borrowed from the Banque de France, where his partner Desprez sat as a director and owned 17.6 percent of the equity, making him by a wide margin the largest single shareholder. The second-largest held 8 percent. Most held less than 1 percent.
In modern terms, the partner of a leveraged investment fund was also the largest equity holder of the central bank, and the firm’s collateral consisted of physical commodities that had not yet been shipped from another hemisphere. By October 1805, Desprez’s exposure to the Banque de France had reached 105 million francs.
This worked exactly as long as the silver kept arriving.
The silver that ran the world
It is hard, from a vantage point in 2026, to grasp how thoroughly silver dominated the financial system of 1805. The Spanish dollar, formally the Real de a Ocho or Peso de a Ocho, was the bitcoin and the dollar of its century combined: minted in Mexico and Peru, shipped through Cádiz, accepted from Canton to Calcutta to Boston. Early central banks, including the Banque de France, the Bank of Amsterdam, and the Bank of England, held Spanish dollars as their primary reserves. Qing dynasty China absorbed staggering quantities of them in exchange for tea, silk, and porcelain. The entire pan-European credit system, denominated in bills of exchange that circulated like modern Eurodollars, assumed that more silver was coming.
What Ouvrard had built was, in essence, a trade financing the conversion of future silver into present credit. Every bill of exchange he discounted, every loan he took out, every advance to the French Treasury, was implicitly an option on the continuing flow of Spanish silver through the Atlantic. The Caja de la Consolidación in Madrid. The Hope partners in Amsterdam. The Baring brothers in London. The receveurs généraux who collected French taxes. The merchant banks of Marseille. All of them held paper that, traced back through enough layers, was an IOU on a galleon that had not yet sailed.
A modern reader will recognize the shape of what comes next.
The news that traveled by horse
On the morning of October 21, 1805, off Cape Trafalgar near the southern coast of Spain, the combined French and Spanish fleet under Vice-Admiral Pierre-Charles Villeneuve met the British Royal Navy under Vice-Admiral Horatio Nelson. By nightfall, eighteen French and Spanish ships had been captured or destroyed. Nelson was dead, shot by a sharpshooter from the rigging of the Redoutable. The British had paid a terrible price for it, but they now controlled, more thoroughly than at any previous moment in history, the Atlantic shipping lanes between Spain and Latin America.
In Paris, no one yet knew.
News from Cádiz to Paris in 1805 traveled at roughly the speed of a man on horseback, about 100 kilometers per day. The 1,800 kilometers between the two cities meant that the most consequential piece of financial information of the decade would not be read in Paris until November 6. The newspaper that carried it, Journal des Arts et des Spectacles, ran the report on November 9.
Two and a half weeks of latency between the event and the price action. There is something darkly amusing about this, in retrospect. Modern markets are obsessed with low-latency trading; firms spend hundreds of millions of dollars to shave microseconds off the trip between Chicago and New Jersey. In 1805, the news that the silver was not coming had to walk.
While it walked, the Banque de France’s discounting peaked. On November 6, the same day the news from Cádiz finally arrived in Paris, the Banque’s outstanding bills of exchange hit their crisis high. At precisely the moment confidence collapsed, exposure was at its maximum.
Three men in a room
The Conseil de Régence of the Banque de France met on October 2, 1805. The directors knew the Cádiz blockade was tightening. They knew the value of Spanish public debt, the vales reales, had collapsed. They knew Desprez was leveraged to the silver shipments. They did not yet know about Trafalgar. They had to decide what to do anyway.
Three positions emerged from that meeting, as documented in the Banque’s minutes and reconstructed by the BIS authors.
Director Benjamin Delessert, a textile manufacturer who would later found France’s first savings bank, argued that the Banque should halt discounts and withdraw support from Desprez. Continued lending, he said, endangered the Banque’s survival. He was, in modern parlance, the moral hazard hawk.
Director Rame argued the opposite. Hesitation had already triggered 25 million francs of deposit withdrawals at Desprez. Continued support, up to 30 million francs through November 11, would prevent panic and, in a phrase that would not feel out of place in the 2008 emergency meetings at Treasury, would “prevent defeating Napoleon in Paris.” He was the systemic-risk dove.
Director Sevene proposed the middle path. Partial support combined with shareholder solidarity to prevent the hoarding of specie. His appeal to moral restraint and the wisdom of the Paris merchant houses reads, two centuries later, like J.P. Morgan’s effort to lock the bankers of New York in a room during the Panic of 1907 until they recapitalized the system.
The Conseil temporized through October. Then, on November 6, the news arrived. On November 7, the conseil de régence explicitly linked excess note circulation to the crisis. On November 8, Delessert renewed his proposal to “suspend discounting until the banknotes were restored to par.” On November 11, the Banque intensified credit rationing, including toward the Treasury.
Between November 6, 1805 and February 11, 1806, the Banque de France cut its discounting of bills of exchange from roughly 120 million francs to 60 million francs. A 50 percent contraction of credit to the productive economy, in three months, achieved by a five-year-old central bank in order to protect itself.
What followed
The Banque de France saved itself. The metallic coverage of its banknotes rose from one quarter at the start of the crisis to 100 percent by late 1806. The Banque hoarded silver. It dispatched a representative to Madrid to extract more. It purchased silver piastres in December despite high prices. It rationed credit to private counterparties.
Approximately twenty major Parisian merchant houses failed. Eight commercial houses in Marseille filed for bankruptcy. The CNR was one of them. So was the house of Récamier, whose own director sat on the Conseil de Régence and watched his firm collapse from the inside. Aggregate annual discounts by the Banque de France collapsed from 847 million francs in 1804 to less than 400 million in 1806. The Banco de San Carlos in Madrid saw its silver reserves drained to near zero as the Paris hoarding pulled specie out of every peripheral market that would yield it.
Pierre Samuel du Pont de Nemours was commissioned to write a report on the crisis in 1806. His son had founded a chemical company in Wilmington, Delaware four years earlier. It is still operating.
The same story, told in oil
Read the previous five paragraphs again and ask yourself which words to change.
In February 2026, the United States and Israel went to war with Iran. The Strait of Hormuz, through which 20 percent of global crude oil and 12 to 14 percent of Europe’s liquefied natural gas had been moving as recently as January, was effectively closed to commercial shipping. Iran imposed a $2 million toll per tanker for transit. War-risk insurance premiums, which had been a baseline 0.125 percent of vessel value, spiked to between 0.2 and 0.4 percent.
West Texas Intermediate, which had traded at $67.02 a barrel on February 27, reached $102.68 by May 18. Diesel rose 49.8 percent. Jet fuel rose 56 percent. Urea fertilizer, the production of which depends on natural gas and the export of which is concentrated in the Persian Gulf, rose 25.9 percent.
The 10-year US Treasury yield spiked to 4.46 percent on March 27, the highest level since July 2025. Equities fell. Bonds fell. The dollar moved with crude oil rather than against it. The classic 60/40 portfolio diversification, which assumes that government bonds rally when stocks fall, did the opposite for six weeks running.
Meanwhile, the central banks of the world did what the Banque de France did in 1805. They hoarded reserves. The asset they hoarded was gold. Annual gold purchases by global central banks, which had averaged about 500 metric tonnes for years, doubled to over 1,000 tonnes in the run-up to the war. By January 1, 2026, Russia’s central bank held gold reserves worth $326.5 billion, or 43.3 percent of its total reserves, at a spot price of $4,400 per ounce. Turkey, facing a currency collapse with the Lira hitting 11 consecutive record lows in 16 trading days, began exploring whether its $135 billion of gold held at the Bank of England could be pledged as collateral for emergency dollar liquidity.
The precipitating event for all of this hoarding was not 2026. It was 2022, when the United States and Europe froze approximately $300 billion of Russian central bank assets following the invasion of Ukraine. From that moment, the world’s non-aligned central banks understood that dollar reserves carried a kind of political default risk that gold did not.
What is the silver of 2026?
The BIS paper makes a careful point. In 1805, the dominant safe asset was Spanish silver. In 2026, it is, in different ways, both gold and oil. Gold, because it sits outside the dollar system and cannot be sanctioned. Oil, because every modern fiat currency is, in the long run, a claim on the productive output of an economy that requires energy to function.
When the supply of either is severed, the consequences are not merely inflationary. They are systemic. The Banque de France in 1805 did not collapse the European economy because silver got expensive. It collapsed the economy because a credit system that had been built on the assumption of continuous silver supply suddenly required everyone to hold actual silver. The contraction of credit was the disaster, not the rise in the price of silver.
This is what investors in May 2026 must understand. The Iran war and the Hormuz closure are not, principally, an inflation event. They are a collateral event. The financial system has been operating on the assumption that energy would continue to flow through chokepoints that turn out to be more vulnerable than anyone had priced. When that assumption breaks, the credit system that depends on it has to recompose itself around different physical assets and different geographies. The companies that own those physical assets, in those geographies, are the silver of 2026.
This report is an attempt to identify them.
Key Findings
The macro thesis is structural, not cyclical.
The BIS framing and the 1805 analogy describe a regime where the central choke point of global trade and credit shifts to physical commodity routes and sovereign collateral. In 1805, the Royal Navy’s Trafalgar victory reorganized capital flows for a generation. In 2026, the Strait of Hormuz closure has done something similar to the assumed permanence of dollar liquidity and just-in-time energy. Investors are being repriced for a world where security of supply, not lowest cost, is the operative metric in energy valuation models, and where central banks treat gold as the politically neutral reserve asset of last resort.
The structural beneficiaries fall into eight buckets.
Energy sovereignty (LNG export, midstream, gas E&P), nuclear and AI power, defense and asymmetric warfare, agricultural inputs, LNG shipping, industrial gases and grid, reinsurance, and real assets (timber, farmland). The thread tying them together is that each owns or sells something that cannot be reshored quickly, manufactured on demand, or substituted away.
The consensus winners are now too crowded for new capital, but quality alternatives are available.
Rheinmetall (up roughly 100 percent since end-2024), Frontline (up 162 percent), MP Materials (up 313 percent), Quanta Services (up 129 percent), Cameco (up 104 percent), Newmont (up 189 percent), and Hanwha Aerospace (up 291 percent) have done their work. Multiple compression is the dominant risk for these names.
The contrarian discipline is to find quality businesses that are exposed to the same structural drivers but have not yet been bid up. We have done that work. Each company profiled in this report was screened to exclude any name up more than 30 percent year-to-date or more than 60 percent since end-2024, then selected on the basis that the underlying business shares the same macro tailwinds as the consensus winners above. Several of the names we discuss are actually down on the year despite the structural backdrop. In our view, the set is available at attractive market quotations relative to underlying business value.
The gold equity opportunity has structurally closed under our criteria.
Every senior producer (Newmont, Agnico, Barrick), royalty company (Franco-Nevada, Wheaton, Royal Gold, Sandstorm, Triple Flag, Osisko), and mid-tier producer we screened is up more than 50 percent since December 2024. Investors who want gold exposure should pursue it via physical bullion rather than equity, since the equity now carries both the gold price beta and a sentiment premium.
The 60/40 portfolio remains structurally broken in the same way.
The 10-year Treasury spiked to 4.46 percent on March 27, 2026 as equities fell and the dollar tracked oil rather than acting as safe haven. The replacement diversifier is real assets with cash yield: midstream, royalty trusts, farmland, infrastructure, and reinsurance with hardening rates.

Theme 1: North American Energy Sovereignty
The Hormuz closure has revealed how dependent Europe and the Asian developed importers are on Atlantic-basin and Pacific-basin LNG and on non-Gulf crude. The structural winners are the US Gulf Coast LNG export complex, the pipelines that feed it, and the upstream gas producers that supply the molecule. The Permian crude royalty trade (Texas Pacific Land, Diamondback Energy) has already moved hard; we now express this theme through the gas-LNG export chain, where multiple names are still attractively priced.
