USDJPY | The Petrodollar Deal And The Real Risk In TokyoUSD/JPYOANDA:USDJPYHowToChart About the Chart: When a Median Line is broken, as shown by the white Lower Median Line in this chart, a test or retest often follows. The main target is the red Center Line, although price does not usually fall there immediately. The yellow Zig Zag therefore represents one possible path toward the red Center Line. Rule #1 in the Alan Andrews Pitchfork framework: The Center Line is reached approximately 80% of the time. The chart presents the technical path. The article below explains the fundamental forces that could support such a move in USDJPY. The following article matters... ...because the current USDJPY situation involves more than interest rate expectations and currency intervention. Japan holds about $1.12 trillion in United States Treasury securities, nearly eight times Saudi Arabia’s position. This makes Tokyo far more important to the Treasury market than the traditional petrodollar story suggests. At the same time, the conflict with Iran has increased Japan’s energy costs and intensified the pressure created by a weak yen. Japanese authorities have already spent about $98.7 billion supporting the currency, with the United States participating in part of the operation. A stronger yen can reduce the pressure that might otherwise encourage Japanese investors to bring foreign capital home. However, official intervention may require Japan to draw down foreign reserves, including Treasury securities. This creates a direct connection between USDJPY, Japanese reserve management and American bond yields. The September yen rally may have reflected expectations of a Bank of Japan rate increase, capital repatriation and the unwinding of yen funded trades rather than another official intervention. Understanding these connections is essential when judging whether the latest move in USDJPY is temporary or the beginning of a larger shift in global capital flows. The Petrodollar Deal That Never Existed. And the Real Risk in Tokyo For half a century, one story has explained American financial power with irresistible simplicity. In 1974, Henry Kissinger supposedly made a deal with Saudi Arabia: sell oil only in dollars, invest the proceeds in U.S. government bonds and receive American military protection in return. It is a memorable story, but it is also misleading. No evidence has emerged of a 50 year agreement requiring Saudi Arabia to sell oil exclusively in dollars. The pact signed on June 8, 1974, created the U.S.–Saudi Arabian Joint Commission on Economic Cooperation. It covered trade, industrial development and closer political ties, but it did not establish exclusive dollar pricing. Saudi Arabia continued accepting British sterling after the commission was created. This distinction matters because reports claiming that the agreement “expired” in 2024 described the end of a contract that apparently never existed. There was, however, a second and more important arrangement. Later in 1974, U.S. Treasury Secretary William Simon led negotiations that encouraged Saudi Arabia to invest its growing oil revenue in Treasury securities. The United States would continue buying Saudi oil while supplying the kingdom with military assistance and equipment. At King Faisal’s request, Saudi Treasury purchases were kept secret. Bloomberg later reconstructed the negotiations using a diplomatic cable obtained from the National Archives. Petrodollar recycling was therefore real. The expiring, exclusive dollar contract was not. The dollar became dominant in oil markets because it was widely accepted and supported by the world’s deepest financial system. Saudi cooperation strengthened that position, but no single document created it. Where the Saudi money went The modern Treasury market looks very different from the popular petrodollar story. In June 2026, Saudi Arabia held approximately $142.5 billion in Treasury securities. Japan held $1.12 trillion, the United Kingdom about $940 billion and mainland China roughly $633 billion. Saudi Arabia’s holdings are large enough to matter, and a sudden sale could unsettle markets, particularly if other investors were selling at the same time. However, the kingdom is not the central pillar of foreign Treasury demand. Japan holds nearly eight times more. Treasury figures also come with an important warning. They are based largely on custodial records, so securities held through accounts in another financial center may not be credited to their true owners. The rankings are therefore estimates, but the difference between Saudi and Japanese holdings remains substantial. Saudi oil wealth has not disappeared. Much of it now flows into sovereign wealth funds and domestic investment. The Public Investment Fund reported about $909 billion in assets under management at the end of 2025. Its 2030 target is SAR10 trillion, or roughly $2.67 trillion. That capital is financing infrastructure, technology, entertainment, sports and large development projects rather than moving automatically from oil sales into Treasury bonds. The war divided the Gulf The conflict with Iran has caused severe damage to Gulf oil production. In 2025, about 20 million barrels of oil and petroleum products passed through the Strait of Hormuz each day, representing roughly one quarter of global seaborne oil trade. Traffic has since been heavily restricted, although it has not stopped completely. Saudi Arabia and the United Arab Emirates have pipelines that bypass the strait, but their available spare capacity is estimated at only 3.5 million to 5.5 million barrels a day. Production fell sharply. OPEC figures supplied directly by member governments show Saudi output declining from about 10.11 million barrels a day in February to 6.87 million in April. Iraqi production fell from 4.14 million to 1.49 million, while Kuwait dropped from 2.58 million to about 560,000. Independent estimates differ slightly, but they all indicate a historic disruption. The financial results were less obvious. A Reuters analysis estimated that Iraq’s March oil export revenue fell 76% from a year earlier, while Kuwait’s declined by 73%. Saudi Arabia moved in the opposite direction. Although its export volume fell, higher oil prices increased its estimated revenue by about $558 million, or 4.3%. Iran gained approximately $1.54 billion, Oman gained about $610 million and the UAE recorded a modest decline of 2.6%. These figures were estimates based on shipping volumes and average Brent prices, not official government receipts. Even so, they show why the argument that every Gulf exporter suffered the same financial shock is inaccurate. Geography determined the outcome. Iraq and Kuwait lacked adequate alternatives to Hormuz, while Saudi Arabia could send oil west to the Red Sea. The countries suffering the largest revenue losses were not major Treasury holders, while Saudi Arabia initially earned more despite producing less. This shifts the focus away from Riyadh and toward the country with the much larger Treasury position. The larger risk is in Japan On September 7, the yen strengthened sharply, reaching about ¥154.05 to the dollar after trading above ¥160 a week earlier. The move led to speculation that Japanese authorities had intervened again. There was no firm evidence of another intervention. Investors were preparing for a possible Bank of Japan interest rate increase, while capital repatriation and the unwinding of yen funded trades also supported the currency. ING noted that a similar move on September 3 produced none of the disruption in electronic trading systems that often accompanies official intervention. This made intervention less likely, though not impossible. The earlier intervention was confirmed. Between July 30 and August 26, Japan spent about ¥15.4 trillion, equivalent to $98.7 billion, buying yen and selling dollars. Part of the operation was coordinated with the United States, making it the first joint U.S.–Japan currency intervention since 2011. Treasury Secretary Scott Bessent said Washington was prepared to act again, although the size of the American contribution was not disclosed. Japan creates a more serious Treasury risk than Saudi Arabia because it combines a trillion dollar bond position with a weak currency and a rising energy import bill. Persistent yen weakness increases import costs and can encourage Japanese investors to hedge their dollar exposure or bring foreign capital home. Supporting the yen may reduce that pressure, which could help limit disorderly sales of foreign assets. However, describing the intervention as a disguised American bond rescue goes beyond the available evidence. Japan also financed its intervention by drawing down reserves held largely in foreign securities, including Treasuries. An operation intended to stabilize the yen may therefore reduce the incentive for private investors to repatriate capital while requiring the government to use part of its own foreign asset portfolio. The intervention may have reduced one risk while creating another. No foreign exodus, yet Foreign Treasury holdings reached a record $9.49 trillion in February 2026, up 6.6% from a year earlier. By June, they had declined to $9.30 trillion but remained above their June 2025 level. These figures do not indicate a mass foreign withdrawal. However, it is also too early to claim that overseas investors are buying without hesitation. The February record came before most of the war’s financial effects, and total foreign holdings have since retreated. The real picture is less dramatic than the myth. There was no expiring petrodollar contract. Saudi Arabia remains important, but it does not control the Treasury market. The Gulf oil shock affected countries unevenly, and higher prices initially protected Saudi revenue. The more credible vulnerability lies in Japan, where currency weakness, rising energy costs and enormous Treasury holdings meet. These pressures help explain why USDJPY now matters far beyond the foreign exchange market. That risk deserves attention, but it should be described as a risk rather than presented as a proven conspiracy. So, the petrodollar legend survived because it made a complicated system easy to explain. But unfortunately, easy explanations are often the ones investors can least afford to trust.
