Quick Take

According to Ecoinometrics, 2023 has marked a distinct shift in the volatility pattern typically associated with Bitcoin. Contrasting with the preceding decade, this year represents a period of unprecedented stability for the cryptocurrency, with volatility rates persistently ranging between 20 to 40%.

Despite this decreased volatility, Bitcoin’s performance has remained robust, delivering 100% returns year-to-date and soaring above the $35,000 mark.

This exceptional stability, combined with solid performance, has resulted in a higher Sharpe Ratio for Bitcoin. As a measure of risk-adjusted performance, a higher Sharpe Ratio signals superior returns for each unit of risk investors endure. In essence, Bitcoin investors in 2023 are receiving more bang for their buck, reaping maximum returns from their investments while staying considerably less volatility compared to previous years.

Another airline is making lounge fees more expensive

Qantas Airways is increasing the price of accessing its network of lounges by as much as 17%.



Over the last two years, multiple airlines have dealt with crowding in their lounges. While they are designed as a luxury experience for a small subset of travelers, high numbers of people taking a trip post-pandemic as well as the different ways they are able to gain access through status or certain credit cards made it difficult for some airlines to keep up with keeping foods stocked, common areas clean and having enough staff to serve bar drinks at the rate that customers expect them.

In the fall of 2023, Delta Air Lines  (DAL)  caught serious traveler outcry after announcing that it was cracking down on crowding by raising how much one needs to spend for lounge access and limiting the number of times one can enter those lounges.

Some airlines saw the outcry with Delta as their chance to reassure customers that they would not raise their fees while others waited for the storm to pass to quietly implement their own increases.

This is how much more you'll have to pay for Qantas lounge access

Australia's flagship carrier Qantas Airways  (QUBSF)  is the latest airline to announce that it would raise the cost accessing the 24 lounges across the country as well as the 600 international lounges available at airports across the world through partner airlines.

More Travel:

Unlike other airlines which grant access primarily after reaching frequent flyer status, Qantas also sells it through a membership — starting from April 18, 2024, prices will rise from $600 Australian dollars ($392 USD)  to $699 AUD ($456 USD) for one year, $1,100 ($718 USD) to $1,299 ($848 USD) for two years and $2,000 AUD ($1,304) to lock in the rate for four years.

Those signing up for lounge access for the first time also currently pay a joining fee of $99 AUD ($65 USD) that will rise to $129 AUD ($85 USD).

The airline also allows customers to purchase their membership with Qantas Points they collect through frequent travel; the membership fees are also being raised by the equivalent amount in points in what adds up to as much as 17% — from 308,000 to 399,900 to lock in access for four years.

Airline says hikes will 'cover cost increases passed on from suppliers'

"This is the first time the Qantas Club membership fees have increased in seven years and will help cover cost increases passed on from a range of suppliers over that time," a Qantas spokesperson confirmed to Simple Flying. "This follows a reduction in the membership fees for several years during the pandemic."

The spokesperson said the gains from the increases will go both towards making up for inflation-related costs and keeping existing lounges looking modern by updating features like furniture and décor.

While the price increases also do not apply for those who earned lounge access through frequent flyer status or change what it takes to earn that status, Qantas is also introducing even steeper increases for those renewing a membership or adding additional features such as spouse and partner memberships.

In some cases, the cost of these features will nearly double from what members are paying now.

“Our results show that PR55α specifically reduces p16 expression […]”

BUFFALO, NY- March 19, 2024 – A new research paper was published in Aging (listed by MEDLINE/PubMed as “Aging (Albany NY)” and “Aging-US” by Web of Science) Volume 16, Issue 5, entitled, “PR55α-controlled protein phosphatase 2A inhibits p16 expression and blocks cellular senescence induction by γ-irradiation.”

Cellular senescence is a permanent cell cycle arrest that can be triggered by both internal and external genotoxic stressors, such as telomere dysfunction and DNA damage. The execution of senescence is mainly by two pathways, p16/RB and p53/p21, which lead to CDK4/6 inhibition and RB activation to block cell cycle progression. While the regulation of p53/p21 signaling in response to DNA damage and other insults is well-defined, the regulation of the p16/RB pathway in response to various stressors remains poorly understood. 

In this new study, researchers Chitra Palanivel, Lepakshe S. V. Madduri, Ashley L. Hein, Christopher B. Jenkins, Brendan T. Graff, Alison L. Camero, Sumin Zhou, Charles A. Enke, Michel M. Ouellette, and Ying Yan from the University of Nebraska Medical Center report a novel function of PR55α, a regulatory subunit of PP2A Ser/Thr phosphatase, as a potent inhibitor of p16 expression and senescence induction by ionizing radiation (IR), such as γ-rays. 

“During natural aging, there is a gradual accumulation of p16-expressing senescent cells in tissues [76]. To investigate the significance of PR55α in this up-regulation of p16, we compared levels of the p16 and PR55α proteins in a panel of normal tissue specimens derived from young (≤43 y/o) and old (≥68 y/o) donors.”

The results show that ectopic PR55α expression in normal pancreatic cells inhibits p16 transcription, increases RB phosphorylation, and blocks IR-induced senescence. Conversely, PR55α-knockdown by shRNA in pancreatic cancer cells elevates p16 transcription, reduces RB phosphorylation, and triggers senescence induction after IR. Furthermore, this PR55α function in the regulation of p16 and senescence is p53-independent because it was unaffected by the mutational status of p53. Moreover, PR55α only affects p16 expression but not p14 (ARF) expression, which is also transcribed from the same CDKN2A locus but from an alternative promoter. In normal human tissues, levels of p16 and PR55α proteins were inversely correlated and mutually exclusive. 

“Collectively, these results describe a novel function of PR55α/PP2A in blocking p16/RB signaling and IR-induced cellular senescence.”

Wall Street Bonuses Fall For Second Year To 2019 Lows Amid Capital Markets Freeze

Wall Street Bonuses Fall For Second Year To 2019 Lows Amid Capital Markets Freeze

Wall Street bonuses have declined for two consecutive years, falling to levels last seen in 2019, according to the latest yearly figures released by New York State Comptroller Thomas P. DiNapoli. This trend is occurring amidst a multi-year downturn in capital markets due to the Federal Reserve's interest rate hiking cycle.

According to the report, the average Wall Street cash bonus fell 2% to $176,500 in 2023, the lowest level since 2019. The drop was far less than the 25% plunge in 2022. Last year's bonus pool was $33.8 billion, unchanged from the previous year but far less than the $42.7 billion during the stock market mania in 2021.

"Wall Street's average cash bonuses dipped slightly from last year, with continued market volatility and more people joining the securities workforce," DiNapoli said in a news release on Tuesday. 

He continued: "While these bonuses affect income tax revenues for the state and city, both budgeted for larger declines so the impact on projected revenues should be limited." 

"The securities industry's continued strength should not overshadow the broader economic picture in New York, where we need all sectors to enjoy full recovery from the pandemic," he added.

Despite the slump, the report said Wall Street's profits rose 1.8% last year, "but firms have taken a more cautious approach to compensation, and more employees have joined the securities industry, which accounts for the slight decline in the average bonus." 

The report showed the industry employed 198,500 people in 2023, up from 191,600 the prior year. This expansion occurred during a period when US banks laid off 23,000 jobs. 

Given that swaps traders and economists at Goldman Sachs Group are forecasting fewer Fed interest-rate cuts this year, a higher-for-longer rates environment will continue to discourage capital-market activity. 

There's about a 50% chance of a June cut. Over the last several months, the Fed's interest-rate target implied by overnight index swaps and SOFR futures went from 700bps of cuts to currently 292bps of cuts for the full year. 

Any delay in the easing cycle will only mean another year of depressed bonuses for Wall Street.
