Governments around the world are making efforts to crack down on teen social media use amid mounting evidence of potential harms, but critics argue blanket bans are an ineffective quick fix.

Australia became the first country to enforce a sweeping social media ban for under-16s in December, requiring platforms like Meta’s Instagram, ByteDance’s TikTok, Alphabet’s YouTube, Elon Musk’s X, and Reddit to implement age verification measures or face penalties.

Several European countries are now looking to follow Australia’s lead, with the U.K., Spain, France, and Austria drafting their own proposals. Although a national ban in the U.S. looks unlikely, state-level legislation is underway.

It comes after Meta, the parent company of Facebook, Instagram and Threads, faced two separate defeats in trials related to child safety and social media harms in March.

A Santa Fe jury found Meta misled users about child safety on its apps. The next day, a Los Angeles jury ruled that Meta and YouTube designed platform features that contributed to a plaintiff’s mental health harms.

These developments are set to “unleash a lot more legislation,” Sonia Livingstone, social psychology professor and director of the London School of Economics’ Digital Futures for Children center, told CNBC.

However, Livingstone said a social media ban for teens is a slapdash solution from governments that have failed to properly police tech giants for years.

“I think the argument for a ban is an admission of failure that we cannot regulate companies, so we can only restrict children,” she said, explaining that the U.S. and Europe already have a lot of legislation in the books that isn’t being enforced.

“When are governments really going to enforce, raise the stakes on fines, ban the companies if necessary for not complying,” she added.

Experts argue the sector has for too long escaped accountability and the rigid requirements faced by other industries.

“[Governments] should be implementing the law [and] big tech companies should be facing a slew of regulatory interventions that forbid a whole series of practices that they currently do,” Livingstone said.

She highlighted the U.K.’s Online Safety Act, which “requires safety by design” — this means features such as Snapchat’s “Quick Add” that invite teens to befriend others should be stopped, according to Livingstone.

Livingstone believes that a blanket ban wouldn’t even be under discussion if social media companies had undergone appropriate premarket testing to establish if their features are safe for their target audience.

“There are lots of areas where we have a well functioning market that requires testing to establish it meets the standards…[before products] can go into the market,” she said. “If we did that for AI and for social media, we would be in a whole different place and we’d not be having to talk about banning children from anything.”

Josh Golin, executive director at Boston-based non-profit Fairplay for Kids, told CNBC that he’d like to see “privacy and safety by design legislation rather than blanket bans” across the U.S.

This includes passing the Children and Teen Online Privacy Protection Act to put a stop to personal data-driven advertising towards children, so there’s “less financial incentive for social media companies to target and addict kids.”

Golin added that passing the Senate’s version of the Kids Online Safety Act (KOSA) is also key to ensuring platforms are held legally responsible for design features that can cause addiction or other harms.

He added that Meta has already successfully lobbied to stop KOSA even though it passed the Senate in 2024. But, if it continues to block legislation further, Golin thinks this could see further pressure “line up behind bans because addictive and unsafe is not OK.”

Many Australian teens flouted the social media ban when it first came into force in December. A BBC report found that downloads of VPNs, which hide users’ locations to avoid country-specific restrictions, increased before the ban.

Additionally, downloads of some apps that weren’t yet affected such as Lemon8, Yope and Discord also surged in the days after the law came into effect, per the report.

“I think it [a ban] certainly gets rid of all the harmful aspects, but it gets rid of the good ones too and I’m just not yet sure if that’s proportionate,” Nash added.

The surging price of jet fuel isn’t the airline industry’s only problem. Now, it’s whether it will have enough.

Since the U.S. and Israel attacked Iran on Feb. 28, the price of jet fuel in the U.S. has nearly doubled, going from $2.50 a gallon on Feb. 27 to $4.88 a gallon on April 2, with the increases even sharper in other regions. The effective closure of the Strait of Hormuz is choking off supplies of both crude and refined products like jet fuel, further driving up the price.

That’s forcing airlines to consider cutting flights, especially overseas.

Carsten Spohr, CEO of Germany’s Deutsche Lufthansa, told employees in a webcast last week that the carrier is assigning teams to come up with contingency plans because of the war in the Middle East, including for drops in demand or a lack of jet fuel, a spokesman said. Those plans could include grounding some of its aircraft.

The U.S. produces a lot of jet fuel and isn’t as exposed as other regions like Europe and parts of Asia are in comparison. But aircraft fill up locally, so some U.S. airlines could face shortages on international trips.

United Airlines CEO Scott Kirby told reporters late last month that the carrier, which has the most service to Asia among U.S. airlines, would have to cut back its flights there. He also said it’s “not impossible” that airlines collectively would have to reduce service in that region.

He noted that as the price of jet fuel goes up, it could be more acute in parts of the U.S. that aren’t as connected by pipelines.

“There’s not enough refining capacity, and so fuel price prior to this and going forward is more susceptible to supply weakness on the West Coast than anywhere else in the country,” he said.

Kirby told employees earlier in March that the airline is preparing for oil to stay above $100 a barrel through 2027 and is pruning some of its flights in the near term.

“To be clear, nothing changes about our longer-term plans for aircraft deliveries or total capacity for 2027 and beyond, but there’s no point in burning cash in the near term on flying that just can’t absorb these fuel costs,” he said in a March 20 message to employees.

Airlines overall are pruning some flights for the coming months, though they often adjust schedules throughout the year to match demand, aircraft availability or other complications.

Domestic capacity in the second quarter for U.S. carriers is up 2.1%, down from previous plans of 2.3% growth, while total capacity is set to rise 1.1%, down from 2.4% on the week ended March 20, according to a Monday report from UBS.

“We expect more capacity cuts in the coming weeks,” UBS said.

So far, airline executives have said that travel demand is strong, but the fuel strains and price spikes are a headache for carriers and passengers alike as the peak summer travel season approaches.

Fuel is generally airlines’ biggest expense after labor, and carriers are already raising airfare and fees like for checked luggage to make up for the added cost.

Investors will be listening for more insights into how the jet fuel spike could affect the industry as airline earnings kick off Wednesday with Delta Air Lines. That carrier owns a refinery, so it could benefit from jet fuel sales.

Delta Air Lines and Southwest Airlines are raising checked bag fees by $10 for tickets, the third and fourth major U.S. carriers to increase prices as the industry grapples with a jump in jet fuel expenses this year.

“As part of an ongoing analysis of the business and against the evolving global backdrop, Southwest Airlines is increasing its fees on first and second checked bags by $10, effective on all reservations ticketed or voluntarily changed on or after April 9, 2026,” Southwest said in a statement.

Southwest Airlines ended its policy allowing all customers to check two bags for free less than a year ago.

The changes would bring the fee to check a first piece of luggage to $45, and $55 for a second bag on each airline. Delta’s changes take effect with bookings starting Wednesday and don’t apply to long-haul international travel but domestic flights and shorter flights abroad.

“These updates are part of Delta’s ongoing review of pricing across its business and reflect the impact of evolving global conditions and industry dynamics,” the airline said in a statement Tuesday.

A third bag on Delta would cost $200 to check.

Last week, United Airlines and JetBlue Airways increased their checked bag fees. Other carriers often follow such pricing moves.

Jet fuel in major U.S. cities was going for $4.69 a gallon on Monday, according to Airlines for America, citing Argus data, up nearly 88% since the U.S. and Israel attacked Iran on Feb. 28. The key Strait of Hormuz shipping channel has remained effectively closed over the past month, choking off global crude and refined fuel supplies.

Delta reports first-quarter results before the market opens on Wednesday, and investors are likely to question executives on how well they are covering the surge in fuel, airlines’ biggest expense after labor. Analysts have pointed to strong demand as a salve for high fuel, but it’s not clear that carriers will be able to cover the entirety of the fuel price run-up.

Danone’s CEO told CNBC that inflationary pressures from the Iran war may force the company to consider price hikes as the outlook for conflict in the Middle East remains highly uncertain.

When asked if the company would be raising prices, CEO Antoine de Saint-Affrique said, “we are not there yet.”

“Nobody knows when [the war] is going to stop, and depending how the next two to four weeks are going to evolve, the outcome from a macroeconomic standpoint, is going to be very, very different,” he told CNBC’s Charlotte Reed.

“If it lasts for long enough, it will have an impact,” he added.

His comments come as companies increasingly take stock of how the war may impact their operations and cost base. 

The conflict in the Middle East has now entered its sixth week, with U.S. President Donald Trump turning up the tone on Iran over the weekend to reopen the Strait of Hormuz. 

The president on Monday said Iran has until 8 p.m. Eastern time to reopen the strategically important strait where normally a fifth of global oil supply passes through.  

The effective closure of the narrow passage has caused not only surging energy prices but also soaring fertilizer and shipping costs. 

The Head of the International Monetary Fund Kristalina Georgieva warned Monday that even if the conflict resolves soon, the Iran war will inevitably lead to higher inflation and weaker growth.

Earlier this month, Britain’s Food and Drink Federation (FDF) forecasted food inflation of at least 9% by the end of the year, revised upwards from an estimated 3.2% previously. That would be the highest annual food and non-alcoholic drink inflation since 2023. 

“Given the fast-changing nature of the situation, this revision is based on assumptions that the Strait of Hormuz opens to cargo traffic within the next two-three weeks and the majority of key facilities, such as oil, gas and fertiliser sites, return to normal within a year,” the FDF said on April 1. 

“If it lasts for long enough, it will have an impact,” de Saint-Affrique said. 

Danone reported a roughly 2.1% overall price increase in the fourth quarter, while volume-led growth stood at 2.5%. 

The company is betting it can capitalize on its healthy brands to remain relevant as food brands also face increasing competition from cheaper private labels that offer grocers higher margins. In March, it announced it would buy protein shake maker Huel for an undisclosed sum to optimize its position in the fast-growing nutrition space. 

Retailers have also warned that they can only absorb increased costs for so long before passing them on to their customers.

British retailer Next said late last month that it had accounted for £15 million ($20 million) of additional costs likely to arise from the Middle East conflict, such as fuel and air freight, assuming the disruption lasts for three months.

“Beyond the next three months, if we see these costs persist, then we will begin to pass costs through as higher pricing,” Next said.

Oil prices edged higher after U.S. President Donald Trump doubled down on his threats to attack Iran’s civil infrastructure, warning that the nation will be “taken out in one night,” if the Islamic Republic’s leadership failed to reopen the Strait of Hormuz.

U.S. West Texas Intermediate crude futures for May were up 0.93% at $113.46 per barrel as of 8:45 p.m. ET. Brent crude for June delivery gained about 0.54% to $110.36 per barrel.

On Monday, Trump repeated his threat that the U.S. will destroy Iran’s power plants and bridges if Tehran did not reopen the Strait of Hormuz by 8 p.m. ET on Tuesday, while also signaling that Iranian leadership was negotiating in earnest.

The closure of the narrow waterway connecting the Persian Gulf and Gulf of Oman has led to a supply shock, sending prices for crude, jet fuel, diesel, and gasoline soaring since the war broke out on Feb. 28.

“They have ’til tomorrow,” the president said. “Now we’ll see what happens. I can tell you, they are negotiating, we think in good faith, we’re going to find out. We’re getting the help of some incredible countries that want this to be ended, because it affects them also.”

Reuters reported that the U.S. and Iran were discussing a framework plan to end their 5-week-old conflict, as Tehran has pushed back against Trump’s pressure to swiftly reopen the Strait of Hormuz, which would allow traffic to start flowing again through the vital energy artery.

Iran has rejected the U.S. ceasefire proposal, presenting its own 10-point plan, according to Axios, including a permanent end to hostilities in the region, rather than a temporary ceasefire, a protocol for safe passage through the Strait of Hormuz, lifting of sanctions, and reconstruction.

But the changes for a ceasefire deal to be reached before the deadline remained slim, according to the report.

Trump responded to the proposal, saying that “They made a … significant proposal. Not good enough, but they have made a very significant step. We will see what happens.”

“As the deadline approaches, [Trump] wants to apply even more pressure to get them across the finish line,” Brain Jacobsen, chief economic strategist at Annex Wealth Management.

Shipping through the Strait of Hormuz is slowly resuming, with 8 tankers transiting Monday, up from the average of fewer than 2 transits per day in March, according to S&P Global Market Intelligence. That, however, is a fraction of the pre-war levels with an average of 20 million barrels of crude oil and products transiting per day via the strait in 2025.

Broadcom said Monday that it’s agreed to produce future versions of artificial intelligence chips for Google, and signed an expanded deal with Anthropic that will give the AI startup access to about 3.5 gigawatts worth of computing capacity drawing on Google’s AI processors.

Shares of Broadcom rose 3% in extended trading.

The disclosure in a securities filing underscores the surging demand for infrastructure that can run generative AI models. Anthropic’s popularity has soared this year, with its Claude app becoming the top free U.S. app listed in Apple’s App Store in February after a dispute between the company and the Pentagon became public.

On an earnings call last month, Broadcom CEO Hock Tan said that “for Anthropic, we are off to a very good start in 2026” in providing 1 gigawatt of compute from Google’s homegrown tensor processing units (TPUs). Broadcom helps Google make its TPUs.

“For 2027, this demand is expected to surge in excess of 3 gigawatts of compute,” he said.

In a note following the earnings call, analysts at Mizuho led by Vijay Rakesh estimated that Broadcom would pick up $21 billion in AI revenue from Anthropic in 2026 and $42 billion in 2027. The filing on Monday did not contain a dollar amount.

Meanwhile, Broadcom is also collaborating with Anthropic rival OpenAI on custom silicon for AI. Both model builders currently rely heavily on graphics processing units from Nvidia through cloud providers such as Amazon, Google and Microsoft. OpenAI has also committed to drawing on six gigawatts of AMD’s GPUs, with the first gigawatt set to come in the second half of this year.

It pinches here; drags there; the draping is wrong. These are some of the examples of the feedback a new crop of artificial intelligence apps might give a prospective customer trying on clothing ahead of a purchase, and in the process reduce the chances of a product being returned to a store.

Fashion retailers are increasingly turning to AI to solve the issue of rising product returns, a persistent drag on profitability and something many in the industry refer to as the industry’s “silent killer”.

A growing number of AI start-ups have emerged to provide virtual try-on technology, allowing potential customers to visualize fit and style before they buy.

While tech companies have attempted to solve online fit issues since the 2010’s, the rapid development of generative AI has finally made these applications good enough to meaningfully impact retailers’ bottom lines. 

The U.S. National Retail Federation late last year estimated that 15.8% of annual retail sales were returned in 2025, totaling $849.9 billion. For online sales, that number jumped to 19.3%. Gen Z is driving this trend, with shoppers aged 18 to 30 averaging nearly eight online returns per person last year, the NRF found.

Most returned items never make it back to the shelves and often cost the retailer more to process than the value of the refund itself. It’s a multibillion-dollar problem for the industry that’s eating directly into companies’ margins.

“Figuring out how to proactively use returns and then how to minimize them can be a meaningful driver of business and profitability,” Guggenheim Senior Managing Director Simeon Siegel told CNBC.

While fit technology will never be as good as trying something on in person, it’s a great way to bridge the gap, Siegel said. “It’s going to continue to get better, I think that’s going to continue to reduce returns.”

The primary reason for returns and abandoned shopping carts is uncertainty over fit, Ed Voyce, founder and CEO of AI startup Catches, told CNBC in an interview.

Catches has developed a platform that allows users to create a “digital twin” to try on clothes virtually with what it calls “mirror-like realism.” The application went live last month on luxury brand Amiri’s website for a select range of clothes.

Unlike other models that Voyce says “just look pretty,” the Catches platform incorporates the physics of fabric texture and how material interacts with a moving body.

“The reason we built Catches was to take advantage of a kind of confluence of technologies that is taking place right now to solve this issue effectively,” says Voyce, who founded the startup backed by LVMH’s Antoine Arnault and built on Nvidia’s CUDA platform.

While e-commerce has grown rapidly in recent years, with online shopping driving retail sales growth, the current U.S. trade policy under President Donald Trump has put a dampener on the sector which relies heavily on manufacturing in Southeast Asia. Across the price spectrum, retailers are struggling to maintain margins as costs rise and consumers become increasingly price sensitive amid inflationary pressures.

The online fast fashion player has been experimenting with virtual try-ons in partnership with deep-tech startup AIUTA, allowing prospective customers to see a piece of clothing on a range of body types, heights, and skin tones. ASOS, however, cautions that the tool is designed to give general guidance and that customers must still check size guides before purchasing. 

Shopify, meanwhile, has integrated startup Genlook’s AI virtual try-on app into its commerce platform, which it says “removes sizing doubts, boosts buyer confidence and drives higher conversion rates while reducing costly returns.” 

Tech giants like Amazon, Adobe, and Google have also created virtual try-ons in various shapes and forms, partnering with major brands to roll out the technology. 

From April 30, Google’s virtual try-on tech can be accessed directly within product search results across Google platforms, according to Google Labs’ website. 

As for Catches, it projects that its app can drive a 10% increase in conversions and a 20- to 30-times return on investment for brand partners. It focuses on luxury brands because of their higher price point. The startup hasn’t yet put a number on how much returns might decline with the use of its platform, but targets “massive reductions.”

“There are certainly companies that have absolutely seen benefits – figuring out how to quantify them is more difficult,” said Siegel. 

While the benefits are clear, the analyst cautions that AI is not a magic wand. Beyond fit, retailers are looking at AI for inventory management, customer targeting, and fraud prevention.

“All of those are really interesting use cases, as long as companies don’t abandon who they are,” Siegel says.

“What you sell is always going to be more important than how you sell, and so I just think remembering that will help dictate who wins and benefits and amplifies from AI versus who gets consumed by it.”

Does it matter where you sit if you’re sipping Champagne in first class? United Airlines is betting that for some travelers looking for luxury at a discount, it doesn’t.

The carrier is launching new, cheaper tiers for its top-end Polaris and premium economy cabins that come with many of the same perks — but plenty of restrictions too.

Starting this spring, United will offer “Base” Polaris fares which will include a spot in the airline’s long-haul business class cabins featuring lie-flat seats, but will charge those customers extra for advanced seat selection.

The new ticket class will also come with only one checked bag instead of two, and with access to the United Club airport lounge but not the higher-end Polaris lounge, which include showers and other plush features. Ticket changes aren’t allowed.

The other categories for Polaris will be “Standard” and the more expensive “Flexible” option that allows for customers to pay up for the new, more spacious Polaris Studio suites.

The new fares show that United — and perhaps soon, other airlines — are dividing up the front of the plane into smaller categories, just as they have with coach over the past decade, from restrictive basic economy tickets to extra legroom fares.

United’s new strategy comes as it overhauls its nearly decade-old Polaris class with new suites that feature sliding doors and bigger screens, while customers continue to show their willingness to pay more to fly in better seats. United and its competitors have been racing to add more premium seating on its planes, sometimes removing some economy seats to do so.

A spokeswoman for United said customers in Base Polaris would get the same meals — including ice cream — as other passengers in the cabin. She declined to say what the price differences between the fares will be, but said the Base Polaris fare is meant to be an entry-level point for the premium class.

United is also launching similar segmentation for its premium economy class, Premium Plus.

The new options will be available in certain markets starting this month and will expand to other international and long-haul domestic markets later this year, United said.

Rival Delta Air Lines last year said it was also considering segmenting front-of-the-plane cabins.

The U.S. was searching for the crew of an American fighter jet Friday after it was downed in Iran, a U.S. official told MS NOW.

It isn’t clear if the plane was shot down or went down for another reason, MS NOW said. The jet was an F-15, which has two crew members, and the whereabouts of the servicemembers was unknown, according to MS NOW.

The Pentagon and U.S. Central Command didn’t immediately comment.

The New York Times said Iran shot down the fighter jet, citing U.S. and Israeli officials and Iranian state media, though MS NOW said it hadn’t independently verified the reporting.

It appeared to be the first known loss of a U.S. jet in the country since the war in Iran started in late February.

The downing of the jet comes at a delicate time, when the U.S. has showed few signs of slowing its assault on Iran and reports of potential peace talks did not yield a breakthrough. The death toll from the conflict is nearing 5,100 across the Middle East, according to MS NOW.

The war has now gone on for more than a month, suffocating tanker traffic through the critical Strait of Hormuz and threatening supplies of crude oil, fertilizer and other key commodities.

President Donald Trump claimed in a social media post Friday that the U.S. could “easily” open the strait, “TAKE THE OIL, & MAKE A FORTUNE.”

Trump also threatened late Thursday to escalate attacks on Iranian infrastructure. He said the U.S. “hasn’t even started destroying what’s left in Iran,” citing bridges and electric power plants.

In remarks Wednesday, Trump said the U.S. would attack Iran “back to the Stone Ages.”
