US retail sales see surprise bounce in August

US consumers buying cars and going to restaurants and bars in August drove a surprise bounce in retail sales, even as spending on gasoline fell as prices at the pump dropped, according to government data Thursday.

Americans flush with savings have been a key driver of the US pandemic recovery and the Federal Reserve is keeping a careful eye on economic data as it battles to quash red-hot inflation without tipping the world’s largest economy into recession.

Retail sales last month rose 0.3 percent compared to July, to $683.3 billion, the Commerce Department said.

But while the headline gain was much better than the flat result economists had projected, the figure for July was revised down to show a 0.4 percent drop, so the August increase means the total remains below the level in June.

The 3.0 percent jump in auto sales was the main factor behind the increase, and when that segment is excluded, retail sales would have declined 0.3 percent, according to the report.

Gasoline stations saw sales drop 4.2 percent following weeks of declining energy costs.

US gas prices at the pump soared in the wake of the Russian invasion of Ukraine in late February, but in recent weeks have been trending down and have fallen by more than $1 a gallon after hitting an all-time high of over $5 in mid-June, squeezing family budgets.

Meanwhile, restaurants and bars rose 1.1 percent, as did building supplies, the report said, but online sales fell.

“Households continue to spend, supported by strong job growth and rising nominal incomes. However, households face headwinds from elevated inflation that is not yet showing any significant sign of abating,” said Rubeela Farooqi of High Frequency Economics.

The data are seasonally adjusted but do not take into account changes in prices, so as costs rise, a shopping dollar does not stretch as far and American families have had to use more of their earnings on staple goods.

The latest consumer price data showing widespread inflation has solidified expectations that the Federal Reserve will announce a third consecutive three-quarter-point interest rate increase at its policy meeting next week.

The central bank has raised the benchmark borrowing rate four times this year, including two massive three-quarter point increases in June and July after US annual inflation spiked to 9.1 percent in June.

While the annual pace slowed to 8.3 percent in August, Fed officials have made it clear they will continue to hike borrowing costs until inflation moves down.

How the tide turned on data centres in Europe

Every time we make a call on Zoom, upload a document to the cloud or stream a video, our computers connect to vast warehouses filled with servers to store or access data.

Not so long ago, European countries were falling over each other to welcome the firms that run these warehouses, known as data centres or bit barns.

Wide-eyed politicians trumpeted investments and dreamt of creating global tech hubs.

But then the dream went sour.

The sheer amount of energy and water needed to power and cool these server farms shocked the public.

The industry sucked up 14 percent of Ireland’s power last year, London warned home builders that power shortages caused by bit barns could affect new projects, and Amsterdam said it simply had no more room for the warehouses.

Then things got worse.

The war in Ukraine helped spark an energy crisis across the continent, leaving consumers facing rocketing bills and countries contemplating energy shortages.

“Data centres will be a target,” critical blogger Dwayne Monroe told AFP, saying the focus would only grow if Europe cannot fix its energy crisis.

Grassroots campaigns and local opposition have already helped to halt projects this year by Amazon in France, Google in Luxembourg and Meta in the Netherlands.

The Irish government, while reaffirming support for the industry, put strict limits on new developments until 2028.

The data industry says it feels unfairly targeted, stressing its efforts to source green energy and arguing that outsourcing storage to bit barns has helped slash consumption.

– ‘Veil of shadow’ –

These arguments are playing out most spectacularly in Ireland.

Activists are campaigning on a broad range of topics and using local forums to push their case.

“They take up a huge amount of space but provide basically no employment,” says Madeleine Johansson, a Dublin councillor for the People Before Profit party, which is campaigning on the issue.

Johansson recently had a motion passed in her council area banning the centres, sparking an almighty row with the national government that is yet to be resolved.

Dylan Murphy of Not Here, Not Anywhere, one of several climate groups pushing the issue in Ireland, has filed a motion in his local council in Fingal calling for companies to reveal the kind of information they are holding.

“There’s a complete lack of transparency… about what data is actually being stored in these data centres,” he said, calling it a “veil of shadow”. 

The data industry says revealing that information would be impossible.

Michael McCarthy of Cloud Infrastructure Ireland, a lobby group, said activists had lost the argument on sustainability and were now throwing everything at the wall. 

“Data centres definitely are large energy users but they’re part of a cohort of larger energy users,” he said.

McCarthy and industry figures in other countries say the real problem is years of underinvestment in national energy infrastructure. 

He also pointed out that the industry in Europe had pledged to become carbon neutral by 2030.

And there are still countries hankering to get data firms to locate there — particularly Iceland and Norway.

– Questions over metaverse –

Against this backdrop, the tech industry continues to innovate new products that invariably require vast amounts of processing power and data storage.

Machine-learning tools, for example, are hugely energy hungry — Google said earlier this year they accounted for between 10 and 15 percent of its total energy usage.

The metaverse, an emerging concept for a 3D internet championed by Facebook owner Meta, would also be hugely energy intensive. 

Critical blogger Monroe reckons the metaverse will buckle under its own weight, partly because of its data requirements.  

“The construction of the metaverse would require Facebook to build out a distribution of data centres that would rival what Amazon, Microsoft and Google have done for their clouds,” he said.

Meta did not respond directly to questions about the metaverse but told AFP that it was “proud to build some of the most energy and water efficient data centres in the world”.

As far as the carbon footprint of such innovation goes, energy experts interviewed by AFP said it would be difficult to assess.

The metaverse, for example, could help to reduce emissions in other areas by reducing the need for travel.

An energy official who did not want to be named questioned whether data centres were the best target for criticism when cryptocurrencies were so wasteful.

While data centres accounted for one percent of global electricity use in 2020, cryptocurrency mining used about half that amount, according to the International Energy Agency.

McCarthy said those who opposed data centres needed to reckon with just how embedded they had become in everyday life, particularly since the coronavirus pandemic.

“They facilitate how we can work and live online, that’s the reality of it,” he said.

Path clear for Swiss purchase of US F-35 fighters

Swiss lawmakers voted Thursday to proceed with the controversial purchase of F-35 fighter jets without holding a referendum sought by opponents of the deal.

The lower house National Council gave the government the go-ahead to buy the 36 aircraft from US manufacturer Lockheed Martin by a large majority.

The upper house, the Council of States where Switzerland’s cantons are represented, has already approved the acquisition.

The Swiss government said last month it planned to go ahead with the acquisition of the combat aircraft despite a petition to hold a popular vote on the issue.

The left-leaning “Stop-F-35” alliance handed over the 100,000 signatures required under Switzerland’s direct democracy system to take any subject to a vote.

But the government said there would not be enough time to hold a vote before Lockheed Martin’s offer for the F-35A aircraft expired, which would have left Switzerland unable to replace its ageing fleet of fighter jets.

Switzerland decided in June 2021 to acquire F-35s and has until March 2023 to sign the contract.

In September 2020, Swiss voters narrowly approved six billion Swiss francs ($6.3 billion) to replace the country’s fleet of F/A-18 Hornets.

The selection of the F-35 sparked some controversy, particularly in light of the cost-overruns of the fighter programme in the United States, but a Swiss parliamentary investigation did not call into question the selection of the fighter.

Switzerland will join a growing number of European countries which have opted for the stealth multi-role combat aircraft, including Belgium, Britain, Denmark, Finland, Italy, Greece, Germany, the Netherlands, Norway, and Poland.

Thai Supreme Court dismisses final Toyota appeal over tax bill

Thailand’s Supreme Court on Thursday dismissed a final appeal by the local subsidiary of car giant Toyota over a disputed $270 million import tax bill following a decade of legal wrangling.

The case relates to Toyota Motor Thailand’s importation of parts for its Prius model at a reduced tax rate between 2010 and 2012 under a Japan-Thailand trade agreement.

Thai authorities said Toyota’s imports were not included under that agreement and estimate the company owes roughly 10 billion baht ($270 million).

While the country’s Central Tax Court ruled in favour of Toyota in 2017, the decision was later overturned.

On Thursday the Supreme court issued a final ruling against Toyota, stating the firm was not eligible for the 30 percent import duty reduction. 

In a statement Toyota Motor Thailand said it “respects the Supreme Court’s ruling”.

But it noted that a 2012 customs ruling — later upheld by the Supreme Court — reinterpreted previously agreed import rules, “resulting in a much higher tax on TMT”.

“Once TMT has obtained the Supreme Court’s full, written decision, we will study the ruling and comply with its requirements,” the statement said.

“We are committed to ensuring that our business practices comply with all applicable government regulations,” the firm added.

The dispute centres on whether the imports should be classified as car parts or fully assembled cars.

The 10 billion baht is comprised of import duty, value-added tax, excise tax, and municipal tax, explained customs department senior official Chaiyut Khumkhun.

“We have yet to see the exact amount Toyota has to pay because we are waiting for the full document of the ruling,” he said.

United States officials are also examining allegations that consultants hired by Toyota Motor Thailand may have attempted to bribe officials over the tax dispute.

In April 2020, Toyota reported possible anti-bribery violations related to its Thai subsidiary to the US Securities and Exchange Commission and the US Department of Justice.

Those two bodies oversee America’s Foreign Corrupt Practices Act — a law that aims to stop businesses from bribing public officials in foreign countries.

The company said it is cooperating with the investigations.

“The investigations could result in the imposition of civil or criminal penalties, fines or other sanctions, or litigation by the DOJ or the SEC,” the company said in a filing made public in March last year.

“Toyota cannot predict the scope, duration or outcome of the matter at this time.”

The firm has operated in Thailand since 1962 and runs three plants employing 13,500 people.

It manufactures about 760,000 vehicles in the Southeast Asian country annually.

Europe stocks waver after inflation-driven rout

European stock markets wavered Thursday after recent heavy losses triggered by higher-than-expected US inflation.

London rose, Paris fell and Frankfurt flatlined nearing the half-way stage.

The yen was under pressure as weak Japanese data further fuelled speculation of possible intervention from the Bank of Japan to support the unit.

Traders were awaiting US retail sales data released later in the day.

Equities suffered a rout on Wednesday as higher-than-expected US inflation stoked concern of more hefty Federal Reserve interest rate hikes.

– ‘Rollercoaster week’ –

“Stock markets are a bit mixed on Thursday following a rollercoaster week in the run-up to, and aftermath of, the US inflation report,” said analyst Craig Erlam at trading platform OANDA.

The data showed US annual consumer price inflation slowing by 8.3 percent in August from 8.5 percent in July but markets had expected a bigger fall.

Asian bourses mostly logged cautious gains Thursday, but Shanghai and Seoul dipped.

Analysts said traders have priced in an expected 75 basis-point interest rate hike by the Fed at a meeting next week.

The data “reinforced expectations that the Fed is going to… proceed with further aggressive hikes until inflation comes back under control,” said Forex.com analyst Fawad Razaqzada.

US producer price data also affected market sentiment, showing costs dropping for the second straight month, mainly driven by falling US fuel prices.

Global consumer prices have soared this year on Russia’s invasion of Ukraine — which has hiked energy and food costs — and because of supply chain strains worsened by Covid lockdowns in China.

Central banks are aggressively hiking interest rates to try and cool prices but this is putting the brakes on economic output, increasing expectations of a global recession.

Ethereum blockchain completes 'monumental' overhaul

Leading cryptocurrency figures hailed on Thursday the completion of one of the biggest software upgrades the sector has ever attempted, an overhaul of the Ethereum blockchain aimed at reducing its massive energy consumption.

Developers had spent years working on an energy-efficient version of Ethereum, a digital ledger that underpins tens of billions of dollars worth of cryptocurrencies, digital tokens (NFTs), games and apps.

Ethereum is the second most important blockchain after bitcoin, but it has faced criticism for burning through more power each year than New Zealand.

“And we finalized!” tweeted Ethereum’s co-creator Vitalik Buterin, calling it a “big moment for the Ethereum ecosystem”.

Buterin quoted research claiming that the “merge”, as developers have called the software upgrade, would reduce global electricity consumption by 0.2 percent.

Enthusiasts hope a more energy efficient Ethereum will spur wider adoption of blockchain technology, particularly for banks and financial firms to automate backend processes.

But so far the technology has been used largely to create speculative financial products.

And critics remain sceptical of the energy saving claims, pointing out that it is unclear how much energy the new system will need.

– Trading resumes –

Blockchain company Consensys called it a “monumental technological milestone” but the scale of the work and potential for glitches led several companies and major exchanges to halt trading during the merge process.

The biggest exchange, Binance, said on Thursday it had resumed trading in ether, the native currency of Ethereum, tweeting: “The Ethereum Merge is complete.”

Ether was down slightly in early trading and has lost more than half of its value since the start of the year, suffering a rout along with the rest of the crypto world as investors shied away from risky assets.

But ether has recovered better than most crypto assets and Edouard Hindi of Geneva-based crypto hedge fund Tyr Capital told AFP the currency was now likely to rise against the dollar and bitcoin as cautious investors begin to buy.

Ether accounts for almost 20 percent of a cryptocurrency market valued at around $1 trillion, according to the site CoinGecko.

The upgrade changes the way transactions are logged on the Ethereum blockchain.

From the start of Ethereum in 2015, so-called crypto miners competed for the prize of adding entries to the blockchain.

They used vast computer power to solve complex equations with only the winners getting the reward, a mechanism known as “proof of work”.

The new system scraps the competition element and eliminates the miners and their energy-guzzling computer stacks.

Instead, potential “validators” need to put up 32 ether (worth $55,000) with the winner chosen in a lottery-style system to update the chain and receive the reward, a system known as “proof of stake”.

“It makes Ethereum much easier to understand conceptually and far less controversial,” Charlie Erith of ByteTree Asset Management told AFP.

He said it would make it harder for investors and regulators to take a tough line on the technology.

However, the upgraded blockchain could face a rocky start.

Some crypto mining companies have already promised to keep running the old mechanism on a smaller blockchain, “forked” from the main Ethereum chain.

And even if the “merge” is successful, Ethereum will remain expensive and slow compared with non-blockchain alternatives.
