The Dollar Brief

Week of September 1, 2026: The Dollar's New Lenders Are Stablecoins and Emergency Swap Lines

Here's a question that would have sounded absurd a year ago: who is actually lending America the money it needs to keep running? For decades the answer was boring and reassuring, namely foreign governments, pension funds, and big banks, all happily parking their savings in U.S. government bonds. This past week's podcasts pointed at two much stranger new answers. The first is a crypto company in the Cayman Islands that now owns more U.S. government debt than Germany. The second is the emergency phone line countries call when they suddenly, desperately need dollars and have nowhere else to turn.

That is the real dollar story right now, and it is more interesting than the daily "will the Fed cut or hold" chatter. Last week everyone stared at the 30-year government bond yield touching 5.3% and argued about whether it was a crisis. This week the conversation moved somewhere deeper and, frankly, more revealing: the plumbing, the hidden pipes that move dollars around the world and decide who has to pay what to borrow them. When you look at the plumbing, you see three things happening at once. Stablecoins are quietly becoming a giant new buyer of American debt. A war in the Middle East is straining the system that gets dollars to countries that need them. And a fight over whether the Federal Reserve can stay independent enough to defend the currency is heating up as a new chairman finds his feet.

(Quick vocabulary, used throughout. "FX" is just foreign exchange, where currencies trade. The "DXY" or dollar index measures the dollar against a basket of other big currencies. A "reserve currency" is the money that the rest of the world holds in savings and uses to trade with each other; the dollar has been the world's reserve currency since World War II. A "Treasury" is a loan to the U.S. government, where a "T-bill" matures in under a year and a "bond" runs 10 to 30 years. The interest a bond pays is its "yield"; prices and yields move in opposite directions, so when buyers back away and prices fall, yields rise. A "stablecoin" is a digital dollar, a crypto token designed to always be worth exactly $1, which the issuer backs by holding real U.S. Treasuries. A "swap line" is an emergency arrangement where the Federal Reserve lends dollars to a foreign central bank that has run short of them. The "carry trade" is borrowing money cheaply in one currency, classically the Japanese yen, to buy higher-paying assets in another. "Yield curve control" is when a central bank stops letting the market set borrowing costs and simply pins them at a chosen level by printing whatever it takes. "Debasement" is letting inflation quietly eat away the value of a currency and the savings held in it. "Fed independence" means the central bank sets interest rates free of the elected government.)

TL;DR

A crypto company now out-owns Germany in U.S. debt, and that's suddenly good for the dollar. On Thoughtful Money (Aug 22), the RIA Advisors team noted stablecoin issuer Tether holds "$135 billion US Treasuries," which is "more Treasuries than South Korea, Saudi Arabia, United Arab Emirates, Germany," and argued the coming "tidal wave" of global stablecoin demand means fresh, steady demand for both the dollar and U.S. debt.
Jackson Hole's theme this year wasn't rates, it was digital dollars. InvestTalk (Aug 22) flagged that the Fed's marquee gathering focused on the roughly "$307 billion" stablecoin market, which is "good for the dollar" in the near term but could "starve traditional banks" of their cheapest funding.
The operator's view: corporate treasurers are suddenly asking about this. Ripple CEO Brad Garlinghouse said on On The Chain (Aug 22) that "only in the last six months" have CFOs started asking how to move "dormant liquidity not earning yield" onto stablecoin rails, calling it "a sea change" toward real institutional use.
The other new lender is an emergency hotline. On The Jay Martin Show (Aug 22), Jay Martin argued the UAE quietly asked the U.S. for a dollar swap line, a move he reads as "a bailout of the Treasury market," with foreign central-bank Treasury holdings at the New York Fed "at their lowest level since 2012."
Japan is the canary, and it's stopped singing. In a companion episode (Aug 23), Martin noted Japanese investors "dumped about $29.6 billion of U.S. bonds" in the first quarter, "their largest exit in nearly four years," as a falling yen and rising Japanese rates force selling.
The Fed-independence fight is now the dollar's biggest wildcard. On WSJ's Take On the Week (Aug 23), former Fed governor Frederic Mishkin called Trump's attacks on the Fed "unprecedented" and worried new chair Kevin Warsh wants to return to opaque, "trust-me" central banking.
A hike would strengthen the dollar and lower long rates, says one pundit. On The KE Report (Aug 22), National Investor editor Chris Temple argued Treasury Secretary Bessent's yield-suppression games are "not going to work," and that if the Fed simply raised rates to show resolve, long yields would "come down."
The buyback is a "liquidity" tell, not a rescue. On Top Traders Unplugged (Aug 22), veteran manager Mark Rzepczynski read the Treasury's bigger bond buyback as a signal of a "liquidity problem" in older bonds, with weekly auctions running "close to $800 billion" at peak.
The doom chorus wants gold, and lots of it. On Palisades Gold Radio (Aug 22), technician Michael Oliver called it "a government bond crisis," a "nuclear event," and said the dollar index is "about to implode."
And the contrarian who says calm down: On Unf*cking The Republic (Aug 23), the host argued replacing the dollar as reserve currency is "decades" away and structurally near-impossible, since "there's nobody else that can," dismissing the "money bad, gold good" panic as a "dog whistle."

What's new

The crypto company that now lends America more than Germany does

Start here, because it reframes the whole "is anyone still willing to fund the U.S." worry. The most striking dollar story of the week was not about a central bank, it was about a stablecoin.

On Thoughtful Money (Aug 22), the RIA Advisors team, whose analyst recently wrote a piece on "US stablecoins and the rebasement of the US dollar," laid out a genuinely counterintuitive idea. A stablecoin is a digital token that always equals a dollar, and the company that issues it backs it by buying real U.S. Treasuries. So every time someone in Zimbabwe or the Philippines swaps their shaky local savings into a dollar stablecoin, that money quietly flows into American government debt. "Tether," they noted, referring to the biggest stablecoin issuer, "had $135 billion US Treasuries. They own more Treasuries than South Korea, Saudi Arabia, United Arab Emirates, Germany… a very, very large accumulator of US Treasuries, and they've been a very steady buyer."

Their punchline is that this is only getting started, and that governments cannot stop it. "It's more of the question of not an if, it's a when," one said. Why unstoppable? Because ordinary people want it. "If you ask them, look, perfect world, what currency would you rather earn your income in… overwhelmingly in most countries, the answer to the regular guy on the street would be, 'Oh, gosh, dollars. I just have a hard time getting a hold of them.' The stablecoin instantly removes all that. So I think from a retail standpoint… there's going to be a tidal wave of demand for stablecoins." They pointed at remittances, the money migrants send home and a top slice of GDP for the Philippines, Mexico and much of South America, where a wire through Western Union can take "3 or 4 or 5 days" and cost a fortune, while a stablecoin transfer is "instantaneous" and free. Any government trying to block its citizens would have to do "some pretty draconian stuff."

Here is why it matters for the dollar specifically: this creates, in their words, "a new proxy for the dollar that doesn't force us to have to print new dollars, and it makes the rest of the world more dependent on the dollar." It is dollar demand America gets for free. Crucially, they argued it is not inflationary the way money-printing is, since "we're not increasing the money supply, we're kind of increasing the supply of dollar-like instruments in the rest of the world."

The same story, told two more ways, and its dark side

The Federal Reserve is taking this seriously enough to make it the theme of its year. On InvestTalk (Aug 22), the host explained that the Jackson Hole Symposium, "pretty much the biggest event of the year for the Federal Reserve," was themed around "financial innovation," which really meant "the stable coin market that is now about $307 billion in size… and how this overall will rewire the plumbing of the financial system if it continues to grow."

He landed on the same near-term conclusion, that "in the near term, it's actually good for the dollar," because frightened savers abroad move "out of their banking system… into stable coins, which effectively then go buy treasuries and go buy dollars." But he flagged the catch that the cheerleaders skip. All that money currently sits in bank checking accounts earning the banks free funding. Move it into stablecoins and "commercial banks would lose the cheapest source of funding," which is "bad for banks… think headwinds for smaller regional banks." And he was honest about the long game: if stablecoins ever become "the majority of the way that we transact, suddenly, yes, that would be a negative on the dollar." For now, he thinks adoption will be "slower than most people in the industry want."

Then there was the operator's-eye view, worth separating from the pundits because it comes from someone actually running the plumbing. Ripple CEO Brad Garlinghouse, on On The Chain (Aug 22), described a real shift in corporate behavior. Ripple's businesses "touched $16 trillion of transactions" last year, he said, but only "about 0.1%" moved on crypto rails. What is changing is the customer conversation: "Only in the last, I'd say, six months now… CFOs and treasurers [are] asking us, hey, my CEO is asking me about stablecoins. We have liquidity all over the world and we have dormant liquidity not earning yield. How can you help us maximize that? How can we unlock some of that trapped capital?… So I think there is a sea change happening because you're seeing real utility." His warning to his own industry was pointed: "You have to have utility. If it's just speculation or meme coins, that's not sustainable."

The emergency hotline: how a Middle East war strains the dollar's pipes

If stablecoins are the surprising new lender, the second new lender this week was the Federal Reserve itself, acting as a last-resort dollar dispenser to a foreign government. This one is a commentator's narrative rather than confirmed fact, so treat the specifics as Jay Martin's telling, but the mechanism is real and worth understanding.

On The Jay Martin Show (Aug 22), Martin argued that a dollar shortage is forming in the world's plumbing because of the war with Iran. His story: with the Strait of Hormuz effectively closed "for about 12 weeks," energy-short countries cannot sell oil and are scrambling for dollars to buy fuel on the open market, and the most liquid thing they can sell to raise those dollars is their pile of U.S. Treasuries. "Foreign central bank holdings of treasuries at the New York Federal Reserve have dropped to their lowest level since 2012," he said. Japan holds roughly "$1.2 trillion," the U.K. "$895 billion," and "these are not small positions."

The centerpiece was his claim that in late April, the UAE, which he says holds "roughly $95.6 billion in US Treasury bonds" plus "$270 billion in foreign exchange reserves," approached Washington for a currency swap line rather than dumping its Treasuries onto a stressed market and spiking yields for everyone. "This is not a bailout of the UAE," Martin argued. "I look at it as a bailout of the Treasury market… everybody is going to be talking about swap lines in the months ahead." The point that matters for the dollar: when a country is forced to sell Treasuries in a hurry, it pushes U.S. borrowing costs up at the worst possible moment, and a swap line is how the Fed defuses that, by quietly creating dollars and lending them out.

Japan: the canary that stopped singing

Martin's companion episode (Aug 23) built the same case around Japan, and it is the clearest explanation of the yen carry trade you will hear this week. His framing: "Japan is the canary and the bird has stopped singing."

The setup: Japan imports "roughly 97%" of its oil, "almost all of it… through the Strait of Hormuz," and carries "around 250%" government debt to its economy, "roughly double the United States." For decades Japan got away with it because its citizens are ferocious savers who bought their own government's bonds and still had enough left over to lend the rest of the world, making Japan "the largest creditor nation on earth" for 34 straight years. Japan also invented the entire modern central-bank rescue kit: zero rates in 1999, quantitative easing in 2001, and yield curve control in 2016. "Everything the Federal Reserve did after 2008… Japan did it first. Washington did not invent the modern central bank playbook. It imported it from Tokyo."

Now, Martin argues, the machine is jamming. An oil shock plus a falling yen creates a "doom loop": "every time the yen drops, Japan's oil bill gets bigger in yen, which forces it to sell even more yen to cover the next purchase… weaker yen, higher oil bill." The yen is now weaker than it has been "in nearly 40 years." The Bank of Japan can no longer play buyer-of-last-resort for its own bonds, because printing more yen only feeds the loop, so Japanese borrowing costs are climbing "to levels the country has not seen in a generation." A currency falling while borrowing costs rise is, he said, "the classic signature of a country losing the confidence of its lenders… a thing that normally happens to fragile emerging markets." And the read-through to America is direct: to raise cash, Japan sells its most liquid asset, U.S. Treasuries. "In the first three months of this year, Japanese investors dumped about $29.6 billion of U.S. bonds, their largest exit in nearly four years."

The fight over whether the Fed can defend the dollar at all

Underneath the plumbing sits a political question that decides everything: can the Federal Reserve stay independent enough to do the unpopular things a strong currency sometimes requires?

The insider was Frederic Mishkin, the Columbia economist and former Federal Reserve governor, on WSJ's Take On the Week (Aug 23). His subject was the new Fed chair, Kevin Warsh, three months into the job. Mishkin's core worry is about transparency. Good central banking, he argued, means the public understands the Fed's "reaction function," how it will respond as the economy changes, because then "the markets will do a lot of the work and heavy lifting for the Federal Reserve" and the economy is less volatile. His fear is that Warsh "talks as if he wants to go back to what was true under Alan Greenspan," the era of "cryptic communication, sort of just trust me, I'm the expert." Mishkin's frame is bigger than one man: "when you look at why countries are rich and other countries are poor, it's all about the institutions… a good institution means that bad people still don't do a terrible job."

But the sharpest point was political, and it goes to the heart of dollar credibility. "The attacks that Donald Trump has made on the Fed are unprecedented," Mishkin said, describing how a norm "codified by Robert Rubin under Bill Clinton," that politicians simply do not lean on the Fed because "if you try to influence the Fed, it's just going to end badly," has been abandoned. He walked through the pressure campaign: the attacks on Jay Powell, the attempt to fire governor Lisa Cook "not for cause," and "the whole outrageous attack from the Department of Justice investigating Jay Powell with no evidence at all." Even Powell staying on as a governor after his term as chair, Mishkin noted, is "really unprecedented." To be clear, Mishkin framed all of this as an institutional and inflation risk and did not make an explicit currency call, but a Fed that markets fear has been captured by a president who wants cheap money is, historically, exactly how a reserve currency starts to lose its shine.

The pundit take came from Chris Temple, editor of The National Investor, on The KE Report (Aug 22), and he connected the politics straight to the currency and to bond yields. His view of U.S. fiscal policy: "borrow until you can't." His view of Bessent's attempts to push long-term yields down by buying bonds: "it's just not going to work because… there's just so much volume of debt that needs to be funded." And his counterintuitive fix echoes an argument that has been building for weeks, that raising rates would actually lower long-term yields: "If the Fed raises short-term yields, what happens to long-term yields? They come down, because number one, you're showing resolve to bring inflation down… and you show that you're not going to let the Treasury push [you] around." Temple's read on the politics is that Bessent got Trump to pick Warsh precisely so the two would "work more closely together" to manage a "$40-plus trillion national debt… this extend and pretend game," which, he argued, has put Warsh "in a terrible place politically, because now it's going to be a lot harder politically for him to raise interest rates, which he needs to do."

The plumbers and the doom-callers

First, the sober technician's read on the Treasury's buyback. On Top Traders Unplugged (Aug 22), veteran manager Mark Rzepczynski explained that when the Treasury doubled its bond buyback "from about $2 billion to about $4 billion a month," it was "basically signaling to the market that we have a liquidity problem" in older, less-traded bonds, a plumbing issue rather than a rescue. He put the sheer scale of America's borrowing in perspective: during heavy refinancing weeks, the government "could be auctioning off close to $800 billion in a given week, which is [an] astounding number," and the Treasury Secretary's job amounts to being "the number one salesman for U.S. bonds around the world." The same explainer surfaced on The Rundown (Aug 22), where Public.com's Zaid Admani tallied the three forces pushing yields up: oil-driven inflation (Brent "above $90 a barrel"), a "$40 trillion" debt with a "$2 trillion deficit," and record corporate borrowing for AI ("$1.9 trillion in investment grade debt this year"). His memorable framing of the government's new competition: "Who would you feel more comfortable lending money to? Google or the U.S. government?"

Then the doom chorus, which you should read as sentiment rather than analysis. The loudest was gold technician Michael Oliver on Palisades Gold Radio (Aug 22): "This is a government bond crisis… a nuclear event. They're going to print, print, print. They have no choice." He sees the dollar index "about to implode" and gold as high as "$8,000 to $9,000" with silver "the most explosive market I can think of." On the fundamentals side, respected Hoisington economist Lacy Hunt, on Thoughtful Money (Aug 22), made a quieter but more rigorous version of the worry: using the old "Fisher equation," he argued all three pieces of a bond yield, the real rate, expected inflation, and the risk premium, are set to rise, with money-supply growth running near "7.5%," far above the roughly 4 to 4.5% he thinks appropriate. His conclusion is the same as the gold bugs', arrived at soberly: "assets that… can't be easily inflated away… the precious metals and other hard assets… are likely to do fairly well."

The contrarian: the dollar isn't going anywhere

For balance, the most bracing counterpoint came from the host of Unf*cking The Republic (Aug 23), reacting to a prominent politician floating the idea of walking away from the dollar's global role. His response was blunt: displacing the dollar as the world's reserve currency is not a policy anyone can choose. "The amount of structural change that would have to happen in the international banking settlement and regulatory system to displace us as the world's reserve currency, just from a structural standpoint, is decades. Also, there's nobody else that can… by design."

His demolition of the usual replacement candidates is worth hearing: Russia is "a kleptocracy"; China is "completely opaque," and crucially "it's very useful for the Chinese to have us be the supplier of dollars to the world," so Beijing does not actually want the burden of reserve status. He does concede the "petrodollar" (oil priced in dollars) could fade "10, 15 years down the road," but that is a different, smaller thing than reserve status itself. His sharpest line was aimed at the mood music: the "money bad, gold good" strain running through the current politics is, he argued, a "currency dog whistle… that isn't real." He did agree on where the real pressure shows up, not the stock market but the bond market, noting that giant tech companies now issue "30-year paper at 5.5%, 6%," giving investors a credible alternative to lending to Uncle Sam, which "reduces the demand and increases the risk premium for U.S. debt."

The debate

Are stablecoins good or bad for the dollar? Good now, genuinely uncertain later, and nobody serious disputes the near-term bid. Every voice that touched it (the RIA team, InvestTalk, Garlinghouse) agreed stablecoins are, right now, a fresh and growing source of demand for both dollars and U.S. Treasuries, because each digital dollar is backed by real government debt and appeals most to savers in weak-currency countries. The disagreement is about the long run and the side effects. InvestTalk's caution, that this drains cheap deposits from banks and could eventually undermine the dollar if it fully replaces normal money, is the honest counterweight to the cheerleaders. The through-line: this is the single most dollar-bullish development discussed all week, and it came from the corner of the market people usually associate with dollar-skepticism.

Can the Fed stay independent enough to defend the dollar? This is the real swing factor, and the week's voices split by vantage point. The insider (Mishkin) sees genuine institutional danger in "unprecedented" political pressure but stops short of a currency call. The pundit (Temple) goes further: the whole point of the new Fed-Treasury coziness is to keep borrowing cheap, which is precisely what erodes a currency over time, unless Warsh defies the pressure and hikes. Both agree the credibility of the Fed and the credibility of the dollar are now the same question.

Is the "dollar is finished" story real? Mostly no on reserve status, genuinely open on the currency's near-term direction. The doom camp (Oliver, and more soberly Lacy Hunt) makes a real point about debasement pressure and why gold keeps climbing. But the contrarian on Unf*cking The Republic has the stronger structural argument on the reserve-currency question specifically: there is no ready replacement, and the one country big enough, China, does not want the job. The honest synthesis: the dollar can weaken, and gold can keep rising, without the dollar losing its throne. Those are two different claims, and the week's loudest voices kept blurring them.

The trades in play

Where podcasts named actual expressions this week (these are speakers' own views and positioning, not advice):

Own gold and precious metals as the debasement hedge. The most consistent trade of the week. Michael Oliver sees gold to "$8,000 to $9,000" and silver as "the most explosive" upside, and favors gold and silver miners over the metal itself on a technical breakout. Lacy Hunt lands in the same place from a rigorous macro read, favoring hard assets that "can't be easily inflated away." Chris Temple tied gold's recent rebound directly to the Treasury's failed interventions.
The stablecoin bid as a structural dollar and Treasury tailwind. The RIA Advisors team frames the "tidal wave" of stablecoin adoption as durable new demand for U.S. debt, with issuers like Tether now among the largest Treasury holders on earth. The flip side they name: a headwind for bank deposits, "think headwinds for smaller regional banks."
The pain trade against the gold crowd is a Fed that actually hikes. Chris Temple's argument is that a rate hike would flatten the curve, pull long yields down, and firm the dollar by restoring resolve, the mirror image of the debasement-and-gold consensus.
Watch corporate credit as the alternative to Treasuries. The read that big-tech 30-year paper at 5.5 to 6% is pulling money out of government debt showed up on both Unf*cking The Republic and The Rundown.

Read-throughs

Stablecoins have quietly become macro. What sounds like a crypto sideshow is now a real driver of Treasury demand and, therefore, of the dollar. If the RIA team and Garlinghouse are right that adoption is accelerating from both retail (remittances) and institutions (corporate treasurers), the U.S. has stumbled into a new, self-reinforcing source of demand for its own debt, one that grows precisely when foreign governments are pulling back.
The plumbing is where the next accident lives. Two separate threads, the swap-line story and the buyback story, say the same thing: the machinery that moves dollars and finances the government is under strain that does not show up in the daily yield headline. Rzepczynski's "$800 billion" auction weeks and Martin's "lowest since 2012" foreign holdings are the metrics to watch, not just the 10-year yield.
Japan is the leading indicator. If Martin's canary is right, watch Japanese Treasury selling and the yen. A disorderly yen and a spike in Japanese bond yields would ricochet straight into U.S. Treasuries via forced selling and a carry-trade unwind, the same accident that hit markets in August 2024.
The dollar's fate now runs through the Fed chair's spine. The cleanest way to read the whole week: does Warsh defend the currency's credibility (hike, resist Trump) or serve the budget (stay easy, keep borrowing cheap)? Mishkin's institutional worry and Temple's political read are two windows onto the same decision.
Separate the two "dollar is dead" claims. Reserve-currency loss (very slow, structurally hard, per the contrarian) is not the same as currency weakness (very possible, and what the gold trade is really betting on). Keeping them apart is the difference between sober analysis and a dog whistle.

What changed this week

The dollar conversation moved from the yield to the plumbing. Last week was about the level of the 30-year bond. This week the smartest discussions were about the pipes underneath: who is buying the debt (stablecoins), who is being bailed out of a dollar shortage (via swap lines), and where the liquidity is breaking (off-the-run bonds, Japan). That is a more sophisticated, and more worrying, place for the debate to have landed.
Stablecoins graduated from crypto story to reserve-currency story. The Fed making digital dollars the theme of Jackson Hole, an operator (Garlinghouse) describing a treasurer "sea change," and a macro shop quantifying Tether's Treasury holdings against Germany's are together a genuine shift in how seriously the mainstream takes stablecoins as a dollar-demand engine.
The Fed-independence risk got a named face and a fresh insider voice. Prior weeks' worry was abstract. This week a former Fed governor put "unprecedented" on the record about the political pressure, and tied the dollar's ultimate backstop, institutional credibility, directly to how the new chair handles Trump.
