The US national debt now stands at a record $40 trillion (€34.4tn), while the Treasury has responded to the bond market pressure by pledging to buy back far more of its own older securities.

Washington’s two announcements landed on the same day and represent two symptoms of the same underlying strain: a government borrowing at a record pace just as buyers of its longest-dated debt are demanding higher returns to keep lending.

Buybacks work like a targeted repurchase. Rather than printing new money, the US Treasury uses cash it already has to repurchase older, harder-to-trade bonds from investors, improving liquidity without changing the total stock of debt.

From 9 September, the maximum size of each buyback operation in the 10-to-20-year and 20-to-30-year markets will at least double, from $2 billion (€1.7bn) to $4 billion (€3.4bn), running through the next quarterly refunding on 4 November.

The US Treasury said the change reflects “strong sponsorship from market participants” in that part of the curve, but the timing of the decision was no accident.

The 30-year yield had climbed on Tuesday to its highest level since 2007 amid what analysts called a buyers’ strike stretching back to late June, aggravated by a swelling supply of corporate debt tied to AI data centre spending.

Yields duly fell after Wednesday’s announcement, with the 30-year dropping roughly 9 basis points and the 10-year around 6, and Wall Street rallied.

Asked whether Americans should worry about the volatility, US President Donald Trump simply said: “No, I don’t think so.”

However, not everyone is convinced the fix goes deep enough.

The size of the increase is modest next to the $32 trillion (€27.5tn) Treasury market it is meant to steady, and notable economist Mohamed El-Erian suggested the outsized market reaction reflected hopes of broader intervention to come rather than the direct effect of the buybacks themselves.

Thomas Simons, chief US economist at Jefferies, said the announcement broke with Treasury’s usual pattern of steady, well-flagged communication about its borrowing plans and felt “shot from the hip”.

How the US national debt reached $40 trillion

The debt figure, confirmed by US Treasury data covering Tuesday, splits into $32.27 trillion (€27.75tn) held by the public and $7.78 trillion (€6.69tn) owed between government accounts.

It arrived roughly two fiscal years earlier than expected as the US Congressional Budget Office projected in May 2023 that the threshold would not be crossed until 2028, and it came remarkably fast even by recent standards: $39 trillion (€33.5tn) was reached only in March, $38 trillion (€32.6tn) the previous October.

The US government borrowed $1.8 trillion (€1.5tn) in the first ten months of this fiscal year alone, already more than it borrowed in the whole of the last one, as spending on Social Security, Medicare, defence and interest payments continues to outrun revenue.

“The national debt is not just a number on the government’s balance sheet,” said David Young, president of the Conference Board’s CEO Center, noting it shapes the financial decisions Americans make daily.

The two stories feed each other.

A bigger debt load makes investors warier about lending long-term, which pushes yields higher. In turn, higher yields then raise the government’s own interest bill, adding further to the debt the US Treasury has to finance next.

Wednesday’s buyback expansion may ease the immediate pressure, but it does nothing to slow the borrowing driving it.

A $1.15 trillion US defence bill passed by the House includes plans to expand military cooperation with Israel through joint work on missile defence, drones and AI. Critics warn the move could deepen ties amid growing political divisions over aid to Israel.

South Korean chipmaker SK hynix, known for its high-bandwidth memory chips, is preparing to raise roughly $28 billion (€24.5bn) on Wall Street, a sum surpassed only by SpaceX’s record flotation last month.

It is an extraordinary outcome for a firm that once survived on job cuts and asset sales.

Pricing is due on Thursday, with trading expected to begin on Friday under the ticker SKHY.

SK hynix is issuing 17.79 million new shares in the form of American depositary receipts (ADRs), each representing a tenth of a Seoul-listed share, and cornerstone investors including Baillie Gifford and funds run by Coatue Management have signalled interest in up to $7 billion (€6.1bn) worth of stock.

The target was trimmed from an initial $29.6 billion (€25.9bn) after the shares slipped in recent weeks.

ADRs are certificates traded on a US exchange that stand in for shares held abroad, letting American investors buy into a foreign company without dealing in a foreign currency or market.

Unlike a conventional flotation, this is not SK hynix’s stock market debut. Its primary listing remains on Seoul’s Kospi index, and the Nasdaq offering simply opens a second, dollar-denominated avenue for investors to gain exposure.

The listing arrives with the company already worth more than $1 trillion (€876bn), a threshold also crossed by rivals Samsung Electronics and Micron, after a surge of more than 200% this year.

Proceeds will fund new fabrication plants, chiefly a vast cluster in Yongin, plus its first US packaging facility in Indiana.

The move is partly about valuation. Korean-listed chipmakers have long traded at a discount to American peers, and a Nasdaq listing offers a chance to close that gap.

The AI memory boom — and the risks

The AI build-out has transformed the industry’s economics.

As hyperscalers pour hundreds of billions into data centres, memory prices have exploded, with DRAM up 44% and NAND flash up 53% in a single quarter, according to Citi Research, and manufacturers have already sold most of their 2026 production.

SK hynix reported first-quarter revenue above 50 trillion won (€29bn) and operating margins north of 70%, figures unheard of for a chipmaker, and commands about 60% of the high-bandwidth memory (HBM) market, according to Counterpoint Research.

Yet the timing is delicate.

Memory has always been a brutally cyclical business. The AI-driven rally that transformed SK hynix has begun to wobble as chip stocks sold off sharply across Asia last week, and Samsung lost more than $100 billion (€87.5bn) in market value despite posting a record profit.

Investors are increasingly asking whether the vast sums being spent on AI infrastructure will earn a return, a question that the Bank for International Settlements raised in late June when it warned that the boom could seed the next financial crash.

Built, broken and rebuilt

Those concerns are not new for SK hynix.

SK hynix traces its roots to Gukdo Construction, founded in 1949, which moved into electronics in 1983 as Hyundai Electronics, an arm of the Hyundai empire.

The Asian financial crisis of the late 1990s brought disaster. Under an IMF-backed restructuring of the Korean economy, Hyundai absorbed rival LG’s semiconductor business, creating a giant that promptly buckled under its own debts.

Salvation came in stages.

Renamed Hynix Semiconductor in 2001, a contraction of “high” and “electronics”, the firm cut jobs, shed assets and split from Hyundai. Profits returned, but the violent swings of the DRAM market left it perpetually exposed.

Starved of capital, it was rescued in 2012 by the telecoms conglomerate SK Group, becoming SK hynix. The takeover proved decisive. SK Group poured money into high-bandwidth memory, then a costly and unprofitable technology that few believed in.

Today it has become the scarcest commodity in AI computing. And the firm employs nearly 46,900 people.

South Korean president frames the push as a race against time to secure the country’s domination in AI boom.

South Korea has laid out a sweeping industrial strategy focused on semiconductor chips and artificial intelligence projects as President Lee Jae Myung pledges to cement overwhelming industry leadership with investments of hundreds of billions of dollars over several years.

Flanked by the heads of the world’s two biggest memory chipmakers, Lee cast the initiative on Monday as a “great leap forward” centred on the “triple axis” of semiconductors, physical AI and data centres.

“We must secure the core elements of AI faster than any other country,” the president said in a televised address.

The world’s two largest memory chipmakers, Samsung Electronics and SK Hynix, will invest 800 trillion won ($518bn) with suppliers to build two new chip fabrication sites each in South Korea’s southwest, Industry Minister Kim Jung-kwan said.

Lee said the country’s southwestern city of Gwangju and South Jeolla province will also invest 5 trillion to 20 trillion won ($3.2bn to $13bn) in the projects. Kim said a further 81 trillion won ($52.5bn) is expected to be invested for a chip-packaging cluster in the Chungcheong area near Seoul.

The government also unveiled plans to build AI data centres in the region, backed by 550 trillion won ($356bn) in investments from the SK Group, GS Group and Naver.

“By 2035, an additional 10-gigawatt AI data centre will be built with a total investment exceeding 18.4 gigawatts and 1,000 trillion won,” or $648bn, Science Minister Bae Kyung-hoon announced.

The announcement marks the government’s boldest push yet to align South Korea’s AI and chip ambitions with Lee’s pledge to narrow regional disparities and revive economies beyond the Seoul metropolitan area.

The opposition has criticised the plan, arguing that his government’s decision to locate a second semiconductor cluster in Honam, the traditional electoral stronghold of his liberal Democratic Party, is driven more by regional politics than by industrial logic.

They have accused the government of pressuring memory chipmakers to invest in the region to bolster political support rather than allowing companies to choose the most commercially viable locations.

As part of the overall initiative, the southwest would be the home of new, large chip production clusters, Lee said, in part to use the rich power resources yet untapped there.

The president defended the proposed southwestern chip hub in a series of X posts over the weekend, rejecting criticism that it favours a region where 85 percent of voters backed him in last year’s presidential election.

June 12 (UPI) — SpaceX began trading Friday at $150 and has gone as high as $176 as SPCX in its initial public offering, the largest one in history.

Elon Musk and SpaceX President and COO Gwynne Shotwell rang the opening bell Friday. Musk was in Texas and Shotwell was at the Nasdaq in New York City.

After trading opened, the stock topped $160, sending the company to more than a $2 trillion market cap. By early afternoon, the stock was at $176.52.

“I love the incredible people of SpaceX beyond words,” Musk wrote Friday afternoon on X.

The company had traded more than 360 million shares as of 2 p.m. EDT Friday. It has more than 172 million shares on the Nasdaq alone, CNBC reported. Polymarket bettors believe, at 70%, that SpaceX will close at more than $2 trillion Friday. Five other U.S. companies have reached the $2 trillion market cap: Nvidia, Apple, Alphabet, Microsoft and Amazon.

Already a trillionaire, Musk is about to be CEO of two of the Top 10 most valuable publicly traded companies at the same time.

Musk said before the IPO that SpaceX had been cash-flow positive since around 2015, CNBC reported. He said he chose to take the company public now to raise capital for “a significant growth phase.” Some plans for that growth include putting more than 100,000 satellites in orbit for communications and building artificial intelligence data centers in space.

“Having a private company was important to us early on because we weren’t really focused on quarterly financials, we were so focused on the long-term outlook for the company,” Shotwell told CNBC in an interview.

Shotwell said interest from investors also helped drive the decision.

“We’ve been feeling, over the last few years, a lot of pressure from everyday Americans and our friends that wanted to buy stock, and there was just no way for these folks to get in,” Shotwell said.

According to its prospectus, SpaceX has had a total loss of $41.3 billion since it was founded in 2002. Originally founded as a maker of reusable rockets, the only profitable part of the business has been the Starlink satellite Internet service.

In February, SpaceX acquired Musk’s startup xAI, which has been embattled this year for its ability to undress people in AI-generated images. Several countries and people have sued the company to force it to not allow the bot to do so against the victims’ will.

Citadel Securities, which helps execute trade orders, processed more retail activity for SpaceX than any other IPO auction on record, CNN reported the company said. Retail investors are regular people trading stocks instead of professionals.
