Global Bond Slump Sends Long-Term Borrowing Costs to Highest in Decades
Longer-maturity bonds are at the epicenter of investor angst about everything from inflation to the debt-laden artificial-intelligence boom — and governments are paying the price.
Sovereign borrowing rates are surging around the world. Yields on 30-year US Treasuries rose to the highest since 2007 this week, while French borrowing costs hit the loftiest since 2008 and their German peers traded at 2011 levels. Equivalent gilt yields are approaching 6% in the UK and similar-maturity Japanese ones are close to their all-time high.
While domestic factors have a role in each market, the structural forces driving up yields are global in nature.
One fear is that an increasingly divided world order will make economies more prone to supply shocks and persistent inflationary pressures. Bondholders are also worried that governments will fail to rein in spending, pressuring fiscal health. Meanwhile, changes in market structure and demographics are resulting in waning demand from once-steady buyers. (…)
US 30-year yields have climbed almost 40 basis points since the end of June to touch 5.32% on Tuesday, the highest level since mid-2007. (…)
Global debt markets have been battered this year by surging energy prices caused by the conflict in the Middle East, which has fueled bets the Federal Reserve and other central banks will tighten monetary policy.
Rising interest rates added to the challenging fiscal backdrop of the world’s major economies. In the US, interest on the public debt continues to be a key driver of the nation’s growing budget deficit. For the fiscal year to date, the tally is $1.17 trillion — a 15% increase, thanks in part to higher yields on Treasuries. (…)
One element acting as a headwind for longer-maturity government debt globally is competition from corporate borrowers. A record pace of bond issuance has added substantial duration supply to US fixed-income markets, especially as tech firms looking to finance AI investment seek to borrow at longer maturities.
These US firms are increasingly tapping overseas bond markets, with one example being Alphabet Inc.’s decision to market a debut Australian dollar debt issue of A$5 billion ($3.6 billion).
The supply challenge comes just as the buyer base is shifting. Traditionally, many bond markets were supported by demand for long-dated assets from the likes of pension funds seeking to match such securities against their liabilities. Nowadays, many providers are moving away from defined-benefit systems, while regulations are encouraging funds to invest more in stocks. (…)
Minutes from the Fed’s June policy meeting show officials were briefed on how ownership of Treasuries was shifting from “relatively price-insensitive official-sector holders to more price-sensitive private investors,” which could impact the term premium — or the extra yield investors demand to hold longer-dated debt. (…)
In Europe, nerves over elevated government borrowing and persistent inflation headwinds have helped push long-term borrowing costs to multi-year highs. France’s 30-year bond yield hit the highest since 2008, with investors turning their attention to the 2027 budget negotiations and next year’s presidential election.
Meanwhile Germany could pay the most in 15 years in a syndicated bond sale of 30-year debt on Tuesday, as the nation’s financing needs increase. In the UK, gilts were rattled in late July after Prime Minister Andy Burnham unnerved investors by saying he would seek fiscal flexibility.
In Japan, outright yield levels remain below their peers but their recent increase has been relentless.
The nation’s relatively steep yield curve reflects speculation that the Bank of Japan has been too slow to raise rates to tame inflationary pressures. That’s on top of other concerns including the central bank’s decision to wind down its bond-buying program, and fears over increased government spending and elevated energy costs.
“The prospect of rising imported energy inflation and mounting pressure for the BOJ to tighten provides little incentive to step in and buy JGBs,” said Prashant Newnaha, a senior Asia-Pacific rates strategist at TD Securities in Singapore. “Japan was meant to be the anchor for global rates, and the risk that JGB yields move higher raises the risk that global duration reprices.”
While concern over price pressure has driven much of the bond selloff, long-dated break-even rates — which measure market expectations for future inflation — have remained relatively well anchored in most major markets. Instead, the rise in borrowing costs has been driven by so-called real yields, or the extra compensation investors demand on top of inflation to hold bonds. (…)
Bloomberg Strategists:
There are many reasons to think yields will be structurally higher this decade, but one important difference is how rising deficits are being financed.
Typically, deficits expand when the economy weakens, accompanied by lower policy rates that help insulate the bond market. However, today’s procyclical fiscal expansion means more government borrowing is pushing yields higher when rates are already elevated.
(…) “We are sticking with our view that the US bond yield should continue to trade in a normal range of 4%-5%, without causing any adverse consequences for the economy and corporate earnings,” the strategists wrote. “Nevertheless, now that the yield is approaching the top of this range, we are monitoring the activities of the bond vigilantes more closely.”
Yardeni pointed to the summer of 2023, when US yields surged from 4% to 5% in just a few months. That level ultimately proved attractive to buyers, and the firm says there may be a similar buying opportunity ahead. (…)
Ed Yardeni, president and chief investment strategist, coined the term “bond vigilantes” in the 1980s to describe investors who sell bonds in protest against government policies they deem inflationary. This drives bond prices down and yields up, forcing authorities back on a course of fiscal restraint.
The firm said bond vigilantes have been stirring around the world in recent months, suggesting concerns over government debt extend beyond the US. They’ve been especially active in the UK and Japan, where debt burdens are especially high relative to the size of their economies, the strategists said.

- From Almost Daily Grant:
The latest look at Uncle Sam’s slipshod finances does little to quell those concerns, as Wednesday brought word that July’s budget deficit totaled $432.3 billion, the largest monthly shortfall since the Covid spending bacchanal in early 2021. Even after adjusting for nearly $100 billion in outlays shifted to July from August, last month’s deficit grew by 14.3% from the same period last year.
Bounding supply of fresh obligations accompanies those torrents of red ink, with the tally of Treasurys held by the public now topping $32.2 trillion, up 8.4% year-over-year and nearly 100% from this time in 2019. The ongoing march higher in benchmark borrowing costs duly serves to aggravate that unwelcome dynamic: interest expense on federal debt now registers at more than 4% of GDP, according to the Government Accountability Office, up from less than 2% as recently as 2022.
Meanwhile, Bianco Research points out that 10-year yields have risen by nearly 100 basis points since the Federal Reserve commenced its most recent easing cycle in fall 2024, which has totaled 175 basis points of rate cuts. In each of the eight previous easing cycles of that magnitude over the past 55 years, 10-year yields declined. “Can the bond market scream any louder, ‘wrong policy?’”, Bianco et al. ask.

Trump Takes Hard Line on Iran as Hormuz Standoff Drags On
(…) A memorandum of understanding the US and Iran signed in June that gave them a 60-day window to negotiate a lasting peace deal technically expired Monday, and when Trump was asked if he would seek an extension, he replied: “No.” (…)
Brent crude climbed as much as 1.1% to $91.85 a barrel on Tuesday — its highest level in more than three weeks — as prospects dimmed for a swift reopening of Hormuz, through which a fifth of the world’s oil and gas transited before the war. (…)
Trump on Monday said the US retains leverage over Iran, citing the naval blockade of its ports. He reiterated his idea of declaring Hormuz an American territory, insisting the US had total control — remarks directly at odds with those of Iranian officials.
Iran and Oman are negotiating a deal on how Hormuz should be managed, but the US isn’t part of those discussions. In a phone interview with Fox News, Trump warned that if “Oman gets in the way we’ll bomb the s—— out of them,” without giving any further details, repeating a similar threat he made in May. Oman isn’t a formal US military ally, but has served as a close security partner. (…)
Trump told Fox News back channels with officials from Iran’s Islamic Revolutionary Guard Corps remain open. An IRGC spokesman later described that assertion as a “delusion,” according to the state-run IRNA news agency.
US Energy Secretary Chris Wright told Fox News earlier on Monday that the American military is “bringing out 8 or 9 million barrels of oil per day” from the region, while crude exports from Iran had halted completely.
Windward yesterday:
EO imagery collected over the Koh-e-Mubarak anchorage on August 14 at 07:07 UTC identified a cluster of approximately 20 vessels — tankers, LPG carriers, and bulk carriers — assessed as conducting sanctions evasion and ship-to-ship transfer activity, with eight OFAC-designated vessels confirmed present.
All sanctioned vessels are operating under OFAC EO13846 and EO13902 designations linked to Iran. (…)
Several vessels have been stationary for extended periods, confirming this location is an established and ongoing shadow fleet aggregation point rather than a transient encounter. New arrivals between August 11 and 14 include four bulk carriers, indicating continued fleet turnover and active operations. Two additional laden dark tankers of approximately 337 and 152 meters and two ballast dark tankers of approximately 237 and 174 meters are also present, likely supporting undeclared cargo transfers. (…)
Iranian anchorages are now visibly functioning as institutionalized evasion infrastructure rather than opportunistic gathering points. (…)
On the Saudi side, the commercial disruption continues to deepen. (…)
Windward assesses the operational risk environment across the Strait of Hormuz, Red Sea, Gulf of Aden, and northern Arabian Gulf as critical, with kinetic incidents recurring against Gulf state shipping, Iranian anchorages operating as established evasion infrastructure, and Saudi export logistics absorbing escalating structural cost.
Windward last week: The Caspian Sea Russia-Iran Corridor Structurally Expands
A Windward analysis covering the 164 days before and after the February 28, 2026 blockade escalation documents a sustained structural shift in Russia-Iran maritime trade through the Caspian Sea. Russian cargo and tanker visits to Iran’s EEZ rose 13%, from 208 to 235, and Iranian vessels visiting Russia’s EEZ rose 7%, from 142 to 152. Wet cargo data shows the same shift more sharply at the shipment level. Russia-to-Iran wet cargo movements rose 2.9 times from 8 to 23 shipments, with volume rising 2.5 times from approximately 174,100 to approximately 437,000 barrels, per Vortexa. Iran-to-Russia flows remain at zero, a one-way supply corridor.
On top of this structural shift, a shorter mid-to-late July window shows a sharper spike, as tanker presence and Iranian anchorage counts combined ran approximately 2.0 times above baseline, 82 versus 42 expected, on top of a tanker baseline already elevated approximately 6.5 times since September 2025. Iran’s own public announcement on July 21 to 22 of a pivot of more than 30% of imports through Russia and Caspian routes directly predicts and spans the full anomaly window.
As of August 8, Iran and Russia officials were actively negotiating a joint roadmap explicitly targeting Caspian Sea logistics, covering facilitation of Iranian essential goods transportation through the Caspian Sea and removal of obstacles to maritime and land trade, alongside the Rasht-Astara railway project.
The dominant signal is structural and deliberate rather than event-driven, assessed as a direct reaction to the Hormuz blockade and a durable expansion of the Russia-Iran bilateral trade relationship.
Iran’s export architecture continues to adapt as the U.S. blockade holds. Kharg Island’s western terminal reactivated for the first time in 25 days, with a VLCC that had been holding since July 11 finally berthed and loading. North Larak anchorage has grown from 28 to 35 hulls in two days, actively absorbing additional sanctioned tonnage. And the Caspian Sea corridor is now measurably functioning as a durable structural workaround, with Russia-to-Iran wet cargo movements 2.9 times higher than pre-blockade levels and both governments actively negotiating a joint logistics roadmap.
Windward assesses [that] Iran’s export architecture [is] visibly adapting through Kharg terminal reactivation, North Larak sanctioned tonnage accumulation, Caspian corridor expansion, and commercial-side protective adaptation to the widening kinetic threat environment.

Canada Inflation Heats Up to 3% in July The consumer-price index rose 0.5% in July, bringing the annual inflation rate to 3%, Statistics Canada says
Canadian inflation accelerated a touch faster than expected last month as prices at the pump again spiked higher, though cost pressures continue to be narrow enough that the central bank isn’t expected to be pushed into lifting interest rates. (…)
Stripping out gas, annual inflation held at 2.2% for a third straight month. (…)
The trimmed mean and weighted median measures of underlying inflation preferred by the central bank averaged 1.95% annually compared with 1.9% a month earlier. Core prices excluding volatile food and energy costs increased by 1.9% from a year earlier after rising 1.8% in June.
“Core inflation remained benign in July, and there continues to be little evidence of widespread passthrough of higher energy prices to the broader CPI basket,” said Michael Davenport, senior economist at Oxford Economics. (…)
Anthropic’s Annualized Revenue Tops $65 Billion Before IPO
Anthropic PBC is on track to generate annualized revenue of more than $65 billion based on its current performance, according to people familiar with the matter, up more than sevenfold from its pace at the end of last year.
The company’s run rate, a metric that projects full-year revenue from a shorter period, hit $65 billion by the end of July, said the people, who spoke on condition of anonymity to discuss private information. Anthropic shared the figures as part of a regular update with investors, one person said. (…)
Anthropic, the developer of Claude and Fable, was valued at $965 billion after a funding round in May, making it one of the world’s largest private companies and eclipsing arch-rival OpenAI’s valuation for the first time.
Anthropic’s revenue run rate topped $9 billion in late 2025 and crossed $47 billion in May. OpenAI’s revenue run rate recently exceeded $40 billion, Bloomberg News has reported, though the two firms may not measure it the same way.
Anthropic reported a preliminary revenue figure of more than $11.5 billion in its latest completed quarter, compared with $787 million in the corresponding period in 2025, according to documents seen by Bloomberg News. It also reported positive adjusted operating income for the quarter, the documents show. (…)
Why AT&T Is Betting Big on Open-Weight AI The telecom company is staking its future on open models, both to control token cost and protect its proprietary data
Corporate America’s AI playbook is changing as more businesses substitute proprietary AI models in favor of open alternatives to save on costs. AT&T’s effort to remake its business for the AI era shows just how far that shift has come.
Such open models currently power about 25% of the telecommunications company’s overall AI usage, including helping manage its network, said AT&T Chief Data and AI Officer Andy Markus, “and we believe we can get way higher than that.”
Over time, he expects open models to power 70% to 80% of the company’s total AI usage.
That conviction has driven Markus to experiment with a number of different open models, including powerful new models from China, which help prevent AT&T from becoming “beholden to any one solution,” he said. (…)
True open-source models allow full access to training data and code, while open-weight models typically share only the numerical parameters, or “weights,” that underlie them.
AT&T uses both open-source and open-weight models.
Because AT&T uses an average of 45 billion AI tokens each day, directing user prompts toward cheaper models makes an impact, Markus said. The company built what it calls a “smart router” to automatically pick the most cost-effective model for a specific task.
Switching from closed, proprietary AI models to open models has already resulted in savings of 80% to 90% for AT&T in certain applications, he said. (…)
AT&T has over a thousand internal uses for AI, from supporting back-office functions like legal and finance to assisting field technicians and running its core network operations. Summarizing and analyzing customer service call transcripts—what Markus describes as an intensive process—is supported entirely by open models, he said.
The work of managing AT&T’s sprawling network is also done by open models. OTel, an open model that AT&T customized using telecom-specific data, supports AI agents that can detect the root cause of network issues, according to Markus.
Another benefit of open models is that they can be run on AT&T’s own data centers rather than rented infrastructure from a cloud-computing provider—a setup that trims AI costs even further. In the future, Markus says the telecom will likely use a mix of cloud-hosted AI models and open models that run on its own hardware.
Although many enterprises say they need the premium capabilities offered by proprietary frontier models, they soon reach an inflection point where the costs of such models become unsustainable, said Chirag Dekate, an analyst at market research and IT consulting firm Gartner.
Plus, they don’t want to risk it all with a single AI vendor, and feel the need to guard their intellectual property from those AI labs, Dekate said.
Over the next two years, open models will underpin more than 50% of use cases for businesses, up from less than 10% today, according to Gartner.
Critics have argued that open models—many of which come from China—present potential risks to national security.
For AT&T, however, using open models is nonnegotiable because of what Markus described as data protection and intellectual property concerns. Open models are generally preferred for data protection because they offer more control over the flow and access of corporate data.
“We have to keep our information safe and protected, and we have to control the inputs and the outputs of the models,” he said. “The enterprise data is the gold mine, and the tools are just a way to mine the gold.”
Enterprises have long sought to keep their proprietary business data away from tech vendors, aiming to keep a strict hold over what they consider their most important assets. The same thinking applies to AI vendors, who train their models on vast amounts of data.
While labs like OpenAI and Anthropic have said enterprise customer data isn’t used for training their models, some companies fear that’s not enough.
“As our data flows through the model ecosystem, we just want to make sure that it is safe and secure from a security standpoint, but also an IP standpoint,” Markus said. “The concept of AI sovereignty has become truly paramount to us.”
See How Europe’s Rivers Are Drying Up and Threatening Its Economy Intense heat and lack of rain have driven water levels across the continent to record lows
Major arteries for trade and agriculture across the continent—including the Rhine, Danube and Po—are now at record low levels, disrupting freight transportation, forcing nuclear power plants to shut reactors and eroding agricultural productivity.
Water levels in the Danube have become so low that the river can no longer supply the cooling water needed for Romania’s only nuclear power plant.
The Cernavodă plant, which supplies about a fifth of Romania’s power demands, shut down in mid-August after the military’s attempts to divert more water toward the plant using explosives didn’t pay off.
At Hungary’s Paks plant, which generates about 40% of the country’s electricity, water shortages have put the facility on the threshold of a shutdown.
In some parts of the Rhine, Western Europe’s principal economic artery, conditions have forced vessels to carry loads as little as 20% of normal capacity, raising shipping costs and disrupting the supply chain.
Italy’s longest river, the Po, is essential for irrigating farmland. The river’s retreat makes it vulnerable to the incursion of sea water from the Adriatic, posing a threat to crops. (…)
Most of the rain that does eventually fall will be absorbed by the parched ground before it can replenish rivers, exacerbating the problem.
The drought across large parts of Europe helped fuel devastating wildfires in France and Spain in July, and there is no respite in sight. Forecasts indicate that hot and dry conditions are likely to persist through August and into September, according to the European Commission.
- The Colorado River Is Shrinking The Colorado River provides water for 40 million people and more than 5 million acres of farmland. But drought and overuse have drained its reservoirs.
(…) Lake Powell’s problems have been exacerbated by exceptionally dry conditions this year. Record-low snowpack in many parts of the Rockies last winter deprived the river of needed replenishment. Runoff into Powell is now far below historic averages.
The dry conditions follow a “megadrought” that has gripped the region since 2000. Reduced river flows have made it harder to meet the needs of states downstream of Powell, leading to more frequent deficits over the last 25 years. (…)
Last month marked a grim milestone: the combined volume of both reservoirs hit their lowest level since 1957, when Glen Canyon Dam was still under construction.
While the recent federal actions offered a lifeline for Powell, they shifted water around rather than addressing systemwide deficits. Jack Schmidt, director of the Center for Colorado River Studies at Utah State University, likened the measures to rearranging deck chairs on a sinking ship. “The ship continues to sink,” he said. (…)
(…) In the more than 15 years, since the government first determined climate change to be a public health danger, there have been more than 29,000 peer-reviewed studies that looked at the intersection of climate and health, with more than 5,000 looking specifically at the United States, according to the National Library of Medicine’s PubMed research database.
More than 60% of those studies have been published in the past five years.
“Study after study documents that climate change endangers health, for one simple reason: It’s true,” said Frumkin, a former director of the National Center for Environmental Health appointed by President George W. Bush.
In a Thursday [Feb. 2026] event at the White House, Trump disagreed, saying: “It has nothing to do with public health. This is all a scam, a giant scam.” (…)

China’s Top Envoy to Visit Seoul as Trump Shakes US-Korea Ties
Chinese Foreign Minister Wang Yi will visit South Korea for two days from Wednesday, stepping up engagement with Seoul as President Donald Trump sows doubts about Washington’s reliability in the region.
Wang will meet South Korean Foreign Minister Cho Hyun to discuss North Korea and bilateral and global issues, South Korea’s Foreign Ministry said in a statement Tuesday. The trip follows renewed high-level exchanges after years of friction over Seoul’s deployment of a US missile defense system opposed by Beijing.
The visit comes after Trump ordered the Pentagon to “substantially reduce” joint exercises with South Korea, citing their cost and his “very good relationship” with North Korean leader Kim Jong Un. The announcement appeared to catch Seoul by surprise. (…)
Wang’s first trip to South Korea in nearly five years will include meetings with President Lee Jae Myung, according to Lee’s office. South Korea expects the talks to advance efforts to restore relations and prepare for high-level exchanges ahead of November’s Asia-Pacific Economic Cooperation summit in the southern Chinese city of Shenzhen.

In the FT: Seoul rattled by Trump’s threat to drills at heart of US alliance
Trump’s language “sounds like he is parroting Pyongyang’s line”, said Mason Richey, professor of international politics at Hankuk University of Foreign Studies in Seoul.
The US president said the drills were “inappropriate and hostile” to North Korea, a country deemed “unthreatening and respectful”. Trump also said his decision was “somewhat related” to Seoul’s refusal to support US military action against Iran — piling further pressure on Seoul. “
This is just another example of how unreliable the US is as an ally right now, whether that be to allies in Asia or Europe,” Richey added. (…)
Trump officials are increasingly frustrated by what they see as Seoul’s foot-dragging in identifying projects for the $350bn of investments it pledged to make in the US in exchange for lower tariffs, according to several people familiar with the situation. (…)
“By scaling these [exercises] down, Trump appears to be extending an olive branch to draw Kim in,” said Victor Cha, Korea chair at the Center for Strategic and International Studies. Trump similarly suspended joint drills that coincided with his summit with Kim in 2018, the first of three meetings between the pair.
Lee has sought to reopen dialogue with Pyongyang and this weekend used an annual liberation day address marking the end of Japanese colonial rule to reiterate calls for “peaceful coexistence” with North Korea.
South Korea’s president’s office, the Blue House, on Monday said it hoped Trump’s comments would lead to renewed US-North Korean talks.
In the seven years since the flurry of Trump-Kim summitry, North Korea has expanded its arsenal of nuclear and conventional weapons, deepened military and economic co-operation with Russia and gained valuable modern battlefield experience in Ukraine.
“Kim has no compelling need to meet now given all the support from Russia and China,” said Cha, who added that the North Korean leader may believe he will have better leverage after US midterm elections in November.
Even if Kim returns to the negotiating table, Seoul could be frozen out. Pyongyang has consistently rebuffed Lee’s efforts to restart inter-Korean dialogue. It has also revised its constitution to formally drop the aim of reunification with South Korea, which it now treats as a separate, hostile state. (…)
The latest episode already appeared to be driving South Korea to pursue a more active role in its own defence.
Lee on Tuesday called for faster progress towards acquiring nuclear-powered submarines and transferring wartime operational control of South Korean forces, which he has pledged to achieve before his presidency ends in 2030. (…)
