The Dollar's Reach Grew This Week While Long-Dated Treasuries Lost Standing, and the Erosion Thesis Treats Them as One Trend

The first working thesis of this desk says that the dollar's role as the world's reserve currency is slowly eroding. This week's record does not support it. The record shows two separate trends moving in opposite directions. The long-dated Treasury bond is losing its standing as the asset no one questions. The dollar's payment and enforcement network is getting larger. A thesis that treats these as one trend points investors at the wrong risk. For a holder outside the United States, the risk is not a falling dollar. The risk is that Washington decides who may hold and move dollars.

Start with the bonds. The 10-year Treasury yield reached 5.34% on October 6, its highest since 2002, and the 30-year yield touched 5.7%. The 30-year ended Friday near 5.60%. The causes are domestic. The federal deficit is close to $1.8 trillion, and President Trump has promised $5,000 to every adult if Republicans hold Congress, a pledge that would cost more than $1 trillion. Federal Reserve minutes show a majority leaning toward another increase by year end. Treasury Secretary Scott Bessent is skipping the IMF and World Bank meetings in Bangkok. Investors are charging the US government more to lend to it for 30 years. That is a repricing of US fiscal credit.

The dollar did not fall as yields rose. It rose with them. On October 6, gold fell as Treasury yields and the dollar rose. On October 7, Iranian tanker attacks pushed oil, the dollar and Treasury yields higher together. Gold has fallen more than 20% since the US-Iran war began in February, during a war, which is the condition in which a reserve alternative should gain. The euro fell to a 17-month low on French debt concerns. Bitcoin, near $82,800, gained less than gold on Friday and moves with risk assets. If foreign holders were selling dollars, long yields would rise while the dollar fell. They moved in the same direction.

The network is also growing. Stablecoin supply stands at $314 billion, of which Tether accounts for $184 billion. Samsung is bringing USDC transfers to 82 million phones, and Kazakhstan's central bank has asked Tether to study a token linked to the tenge. Each of these tokens is a claim on dollar reserves, and its issuer can freeze it. On October 9, Tether froze four THORChain vaults without warning. The payments company Conduit is suing Tether over a frozen balance of $2.76 million tied to a Brazilian investigation. Bessent says the United States will probably seize $1 billion of Iranian crypto this week, and past US actions of this kind have relied on stablecoin issuers. Dollar enforcement now reaches wallets that correspondent banks never served.

Enforcement now depends on what the president wants. In the same week, Washington sanctioned the International Criminal Court as an institution, which puts sanctions risk on the European banks that serve the court, and it suspended sanctions on Russian diesel until April under a supply deal with President Vladimir Putin. The White House turns the rules on and off according to its interests. For holders, that is a political risk. It is not evidence that the dollar's reserve role is shrinking.

The strongest form of the opposing case is that discretion causes erosion, with a delay. Each seizure teaches governments and companies to diversify. Russia's central bank has cleared Sberbank and VTB to hold bitcoin, and Russians have opened 220,000 digital-ruble accounts. China has ordered a national blockchain network. Japanese institutions sold foreign bonds. Central bankers told Reuters that gold remains a core reserve asset. On this view, yields near 2002 levels are the price that cautious foreign buyers now demand.

The answer is that erosion needs an alternative that keeps its value and can actually be used. Look at the alternatives on offer. Sberbank's planned custody service includes Tether, which is a dollar token, and requires identity checks on every transaction. Russians are choosing cash over bank deposits. China's network is state infrastructure that operates inside capital controls. The Reserve Bank of India cut the limit on rupee derivatives from $100 million to $5 million, and Thailand added paperwork to slow inflows. The governments that issue the alternative currencies are tightening control over them. The Japanese bond sales made dollar funding more expensive, which is a sign of demand for dollars, not of falling demand.

Three things would prove this argument wrong. First, long yields rising while the dollar falls over several sessions, because that combination means foreigners are selling US assets. Second, gold rising together with real yields instead of against them. Third, stablecoin supply contracting while a non-dollar token gains share. A fourth test is political. If European banks keep serving the court without penalty, US enforcement reach stops at the European Union's border.

Four events in the next seven days will test the argument. The September consumer price index is scheduled for October 14. A high reading would push yields and the dollar up together, which supports this view. The Bangkok meetings will show whether finance ministers use Bessent's absence to push settlement in other currencies, or only complain about it. Bessent's Iranian seizure will show its method. A seizure carried out through an issuer freeze confirms that stablecoins extend US power, and a failed seizure weakens the claim. Iran has also said it will answer the US Hormuz counteroffer within days, and that answer will move oil and, with oil, the dollar.
