How big is Bitcoin’s carbon footprint?

  • Concerns mount about the way bitcoin is ‘mined’ using fossil fuels

LONDON: Tesla boss Elon Musk’s sudden u-turn over accepting bitcoin to buy his electric vehicles has thrust the cryptocurrency’s energy usage into the headlights.

Some Tesla investors, along with environmentalists, have been increasingly critical about the way bitcoin is “mined” using vast amounts of electricity generated with fossil fuels.

Musk said on Wednesday he backed that concern, especially the use of “coal, which has the worst emissions of any fuel.”

So how dirty is the virtual currency?

Power hungry

Unlike mainstream traditional currencies, bitcoin is virtual and not made from paper or plastic, or even metal. Bitcoin is virtual but power-hungry as it is created using high-powered computers around the globe.

At current rates, such bitcoin “mining” devours about the same amount of energy annually as the Netherlands did in 2019, data from the University of Cambridge and the International Energy Agency shows. Some bitcoin proponents note that the existing financial system with its millions of employees and computers in air-conditioned offices uses large amounts of energy too.

Coal connection

The world’s biggest cryptocurrency, which was once a fringe asset class, has become increasingly mainstream as it is accepted by more major US companies and financial firms. Greater demand, and higher prices, lead to more miners competing to solve puzzles in the fastest time to win coin, using increasingly powerful computers that need more energy.

Bitcoin is created when high-powered computers compete against other machines to solve complex mathematical puzzles, an energy-intensive process that often relies on fossil fuels, particularly coal, the dirtiest of them all.

Green Bitcoin?

Bitcoin production is estimated to generate between 22 and 22.9 million metric tons of carbon dioxide emissions a year, or between the levels produced by Jordan and Sri Lanka, a 2019 study in scientific journal Joule found.

There are growing attempts in the cryptocurrency industry to mitigate the environmental harm of mining and the entrance of big corporations into the crypto market could boost incentives to produce “green bitcoin” using renewable energy. Some sustainability experts say that companies could buy carbon credits to compensate for the impact. And blockchain analysis firms say that it is possible in theory to track the source of bitcoin, raising the possibility that a premium could be charged for green bitcoin. Climate change policies by governments around the world might also help.

Alternative energy

Projects from Canada to Siberia are striving for ways to wean bitcoin mining away from fossil fuels, such as using hydropower, or at least to reduce its carbon footprint, and make the currency more palatable to mainstream investors.

Some are attempting to repurpose the heat generated by the mining to serve agriculture, heating and other needs, while others are using power generated by flare gas — a by-product from oil extraction usually burned off — for crypto mining.

China crisis

The dominance of Chinese miners and lack of motivation to swap cheap fossil fuels for more expensive renewables means there are few quick fixes to bitcoin’s emissions problem, some industry players and academics warn. Chinese miners account for about 70 percent of production, data from the University of Cambridge’s Center for Alternative Finance shows. They tend to use renewable energy — mostly hydropower — during the rainy summer months, but fossil fuels — primarily coal — for the rest of the year.


Sterling set for worst week since Sept. 2020

Sterling set for worst week since Sept. 2020

LONDON: Sterling extended its fall against the US dollar on Friday, dropping below $1.39, hurt by the US Federal Reserve’s hawkish surprise and an unexpected fall in Britain’s retail sales.
The pound dropped against a strengthening dollar on Thursday after the Fed surprised markets by signaling it would raise interest rates and end emergency bond-buying sooner than expected.
On Friday, it fell further against both the dollar and the euro. It was down 0.3 percent on the day at $1.389, having touched as low as $1.38555 — its weakest since May 4. It was on track for its worst week since September 2020.
Versus the euro, it was down around 0.3 percent at 85.78 pence per euro, on track for a small weekly fall.
“GBPUSD remains bogged down below the 1.39 handle by a confluence of broad USD strength and a slight deterioration in near-term data,” said Simon Harvey, senior FX market analyst at Monex Europe.
“The limited impact of the data on sterling is largely because retail sales volumes remain above pre-pandemic levels and a shift in consumption patterns toward services after the May 17th reopening was always likely.”
For cable, market participants are weighing up the Bank of England and the Fed’s relative pace of possible monetary policy tightening. The BoE next meets on June 24.
BofA strategists said in a note to clients that it changed its view on the central bank’s tightening trajectory.
and now expects a 15 basis point rate hike in May 2022, compared to previously expecting no hikes in 2022.
“Brussels’ patience with London’s having its cake and eating it is wearing thin. Indeed, there is a risk of protocols being triggered and tariffs being threatened more seriously,” wrote ING strategists in a note to clients.
“The next few weeks could thus be a vulnerable period for Cable, where a break of 1.3890 opens up 1.3800/3810 — the last stop before an extension to the March/April lows of 1.3675.”

Bahrain’s Batelco could be first stock to be dual listed on Tadawul

  • Samba has been hired as an adviser on the deal

RIYADH: Bahrain Telecommunications Co. (Batelco) is planning to become the first company to have a dual listing of shares on Saudi Arabia’s stock exchange (Tadawul), Bloomberg reported citing people familiar with the matter.

The investment arm of Samba Financial Group has been hired as an adviser on the deal, the people said, asking not to be identified for information privacy.

No decision has been made and the company may decide against the dual listing, they said.

A spokesperson at Batelco declined to comment, while Samba Capital didn’t respond to messages seeking comment, Bloomberg said.

Tadawul has been trying to encourage Middle Eastern firms to dual list for years, without success. Aluminium Bahrain had considered a dual listing in 2014, but it never occurred.

Saudi Arabia’s National Debt Management Center wins global awards for second year

  • Saudi office won Middle East and emerging market awards

RIYADH: Saudi Arabia won the Best Sovereign Public Debt Office in the Middle East and the Most Impressive Emerging Market Issuer Award at the 2021 Global Capital Bond Awards, for the year 2021, for the second year in a row, SPA reported.

The Global Capital Bond Awards honors the achievements of governments and companies of all sizes in the field of sovereign and regional finance, banking services, hedge funds, and many other areas within the financial services sector.

It also highlights the most prominent innovations and achievements within the financial services sector, globally.

Saudi Arabia sold SR8.27 billion ($2.20 billion) of riyal-denominated sukuk in June, up from $941 million in May, bunt down from $3.1 billion April, National Debt Management Center data show.

“Driving growth of the Kingdom’s capital markets will be an increase in bond issuance to help fund the SR12 trillion Vision 2030," said Khalid Al-Bihlal, head of S&P Global Ratings KSA. "We project a gradual rise in the use of Saudi Arabian riyal-denominated bond issuance as the local capital markets develop. The US dollar is currently the currency of choice for such bonds."

Oil falls amid dollar strength; demand picture still bullish

Oil falls amid dollar strength; demand picture still bullish

  • Prices remain close to multi-year highs
  • Dollar jumped since Fed moved rate-hike forecast forward

LONDON: Oil prices fell for a second straight session on Friday as the US dollar soared on the prospect of interest rate hikes in the United States, but they were on track to finish the week little changed and only slightly off multi-year highs.
Brent crude futures were down 64 cents, or 0.9 percent, at $72.44 a barrel as of 9:00 a.m. GMT, extending a 1.8 percent decline on Thursday. The contract is set to be largely steady for the week.
US West Texas Intermediate (WTI) crude futures were down 53 cents, or 0.8 percent, at $70.51 a barrel, after retreating 1.5 percent on Thursday and is also set to be flat on the week.
On Wednesday, Brent settled at its highest price since April 2019 while WTI settled at its highest since October 2018.
“Oil markets retreated sharply overnight as a stronger US dollar and falling commodity prices elsewhere saw the overbought technical correction continue,” said Jeffrey Halley, senior market analyst at OANDA.
The dollar has rocketed in the two sessions since the US Federal Reserve projected possible rate hikes in 2023, earlier than market watchers previously expected. A rising dollar makes oil more expensive in other currencies, curbing demand.
The prospect of rate hikes also weighed on the longer-term growth outlook, which would eventually hurt oil demand, in contrast to the near-term outlook for growth in demand as COVID-19 related curbs on movement and business activity ease and road and air travel pick up, said Westpac senior economist Justin Smirk.
“The near term’s all very positive. The question is how much further can it rise, how much scope is there if you’re looking at an environment where interest rates are going to rise,” Smirk said.
Oil prices also fell after Britain on Thursday reported its biggest daily rise in new cases of COVID-19 since Feb. 19, with government figures showing 11,007 new infections versus 9,055 a day earlier.
Adding to negative sentiment were remarks from Iran’s top negotiator on Thursday saying talks between Tehran and Washington on reviving the 2015 Iran nuclear deal have come closer than ever to an agreement.
