A new paper co-authored by Ethereum’s Vitalik Buterin highlights the use of zero-knowledge proofs as a tool for regulatory compliance and on-chain privacy.

Ethereum co-founder Vitalik Buterin has published a research paper diving into privacy pool systems as a tool to achieve more privacy in financial transactions, allowing users to prove dissociation from illicit funds through zero-knowledge-proof technology.

The document initially discusses one of the most popular privacy-enhancing protocols, Tornado Cash, which allows users to deposit and withdraw cryptocurrencies without creating an identifiable link between the two addresses. Recently, United States authorities filed criminal charges against its founders, alleging extensive use by bad actors.

"The critical issue with Tornado Cash was essentially that legitimate users had limited options to dissociate from the criminal activity the protocol attracted," reads the paper, co-authored by Jacob Illum, Matthias Nadler, Fabian Schar and Ameen Soleimani.

The analysis then elaborates on an extension of Tornado Cash’s approach that would enable users to publicly prove the source of funds on-chain by allowing membership proofs (“I prove that my withdrawal comes from one of these deposits”) and exclusion proofs (“I prove that my withdrawal does not come from one of these deposits").

According to the authors, the concept could provide a balance between honest and dishonest protocol users, potentially enabling financial compliance on-chain in the future:

“The core idea of the proposal is to allow users to publish a zero-knowledge proof, demonstrating that their funds (do not) originate from known (un-)lawful sources, without publicly revealing their entire transaction graph. This is achieved by proving membership in custom association sets that satisfy certain properties, required by regulation or social consensus."

With privacy pools, users can exclude themselves from anonymity sets that include addresses related to illegal activities based on zero-knowledge proofs — a method of proving a statement without disclosing the statement’s details.

The underlying idea presented in the document asserts that instead of simply using zero knowledge to prove that a “withdrawal is linked to some previously-made deposit, a user proves membership in a more restrictive association set."

The association set can include all previously made deposits, only the user’s own deposits, or anything in between. As a public input, the user specifies the set by providing its Merkle root. “For simplicity, we do not directly prove that the association set actually is a subset of the previously-made deposits; instead, we just require the user to zero-knowledge-prove two Merkle branches."

To illustrate it in a law enforcement context, the authors provide a simple example:

“Suppose that we have five users: Alice, Bob, Carl, David and Eve. The first four are honest, law-abiding users who nevertheless want to preserve their privacy, but Eve is a thief. Suppose also that this is publicly known."

In the example, when one of the users wants to withdraw funds, the individual can specify which association set to be a part of, meaning users are incentivized to make their association sets larger to safeguard privacy. However, to avoid their funds from being perceived as suspicious by merchants or exchanges, the users do not include Eve in their association set. Eve, however, cannot exclude her own deposit and will be forced to make an association set equal to the set of all five deposits.

“[W]e assume that Alice, Bob, Carl and David include all other 'good’ deposits in their respective association sets and exclude deposit 5, that originates from a known illicit source. Eve, on the other hand, cannot create a proof that disassociates her withdrawal from her own deposit." 

According to the authors, the example illustrates one possibility for the use of association sets in privacy pool protocols. "Note, that the system does not rely on altruism on Alice, Bob, Carl and David’s part; they have a clear incentive to prove their disassociation." 

The paper further offers several other use cases of zero-knowledge proofs for users to demonstrate that funds are not tied to illicit sources or to prove that funds originate from a specific set of deposits without revealing any further information.

“In many cases, privacy and regulatory compliance are perceived as incompatible. This paper suggests that this does not necessarily have to be the case, if the privacy-enhancing protocol enables its users to prove certain properties regarding the origin of their funds."

Protocols working on zero-knowledge solutions are on the rise, with the Ethereum network dominating major launches, according to recent research. The findings point out that scaling ZK-proof solutions are set to experience the highest growth in the coming 12 months as global regulations evolve and users seek to protect their privacy.

Today, in the Calculated Risk Real Estate Newsletter: Q4 Update: Delinquencies, Foreclosures and REO

A brief excerpt:
I’ve argued repeatedly that we would NOT see a surge in foreclosures that would significantly impact house prices (as happened following the housing bubble). The two key reasons are mortgage lending has been solid, and most homeowners have substantial equity in their homes..
...
And on mortgage rates, here is some data from the FHFA’s National Mortgage Database showing the distribution of interest rates on closed-end, fixed-rate 1-4 family mortgages outstanding at the end of each quarter since Q1 2013 through Q3 2023 (Q4 2023 data will be released in a two weeks).

This shows the surge in the percent of loans under 3%, and also under 4%, starting in early 2020 as mortgage rates declined sharply during the pandemic. Currently 22.6% of loans are under 3%, 59.4% are under 4%, and 78.7% are under 5%.

With substantial equity, and low mortgage rates (mostly at a fixed rates), few homeowners will have financial difficulties.

'Bougie Broke' - The Financial Reality Behind The Facade

Authored by Michael Lebowitz via RealInvestmentAdvice.com,

Social media users claiming to be Bougie Broke share pictures of their fancy cars, high-fashion clothing, and selfies in exotic locations and expensive restaurants. Yet they complain about living paycheck to paycheck and lacking the means to support their lifestyle.

Bougie broke is like “keeping up with the Joneses,” spending beyond one’s means to impress others.

Bougie Broke gives us a glimpse into the financial condition of a growing number of consumers. Since personal consumption represents about two-thirds of economic activity, it’s worth diving into the Bougie Broke fad to appreciate if a large subset of the population can continue to consume at current rates.

The Wealth Divide Disclaimer

Forecasting personal consumption is always tricky, but it has become even more challenging in the post-pandemic era. To appreciate why we share a joke told by Mike Green.

Bill Gates and I walk into the bar…

Bartender: “Wow… a couple of billionaires on average!”

Bill Gates, Jeff Bezos, Elon Musk, Mark Zuckerberg, and other billionaires make us all much richer, on average. Unfortunately, we can’t use the average to pay our bills.

According to Wikipedia, Bill Gates is one of 756 billionaires living in the United States. Many of these billionaires became much wealthier due to the pandemic as their investment fortunes proliferated.

To appreciate the wealth divide, consider the graph below courtesy of Statista. 1% of the U.S. population holds 30% of the wealth. The wealthiest 10% of households have two-thirds of the wealth. The bottom half of the population accounts for less than 3% of the wealth.

The uber-wealthy grossly distorts consumption and savings data. And, with the sharp increase in their wealth over the past few years, the consumption and savings data are more distorted.

Furthermore, and critical to appreciate, the spending by the wealthy doesn’t fluctuate with the economy. Therefore, the spending of the lower wealth classes drives marginal changes in consumption. As such, the condition of the not-so-wealthy is most important for forecasting changes in consumption.

Revenge Spending

Deciphering personal data has also become more difficult because our spending habits have changed due to the pandemic.

A great example is revenge spending. Per the New York Times:

Ola Majekodunmi, the founder of All Things Money, a finance site for young adults, explained revenge spending as expenditures meant to make up for “lost time” after an event like the pandemic.

So, between the growing wealth divide and irregular spending habits, let’s quantify personal savings, debt usage, and real wages to appreciate better if Bougie Broke is a mass movement or a silly meme.

The Means To Consume 

Savings, debt, and wages are the three primary sources that give consumers the ability to consume.

Savings

The graph below shows the rollercoaster on which personal savings have been since the pandemic. The savings rate is hovering at the lowest rate since those seen before the 2008 recession. The total amount of personal savings is back to 2017 levels. But, on an inflation-adjusted basis, it’s at 10-year lows. On average, most consumers are drawing down their savings or less. Given that wages are increasing and unemployment is historically low, they must be consuming more.

Now, strip out the savings of the uber-wealthy, and it’s probable that the amount of personal savings for much of the population is negligible. A survey by Payroll.org estimates that 78% of Americans live paycheck to paycheck.

More on Insufficient Savings

The Fed’s latest, albeit old, Report on the Economic Well-Being of U.S. Households from June 2023 claims that over a third of households do not have enough savings to cover an unexpected $400 expense. We venture to guess that number has grown since then. To wit, the number of households with essentially no savings rose 5% from their prior report a year earlier.  

Relatively small, unexpected expenses, such as a car repair or a modest medical bill, can be a hardship for many families. When faced with a hypothetical expense of $400, 63 percent of all adults in 2022 said they would have covered it exclusively using cash, savings, or a credit card paid off at the next statement (referred to, altogether, as “cash or its equivalent”). The remainder said they would have paid by borrowing or selling something or said they would not have been able to cover the expense.

Debt

After periods where consumers drained their existing savings and/or devoted less of their paychecks to savings, they either slowed their consumption patterns or borrowed to keep them up. Currently, it seems like many are choosing the latter option. Consumer borrowing is accelerating at a quicker pace than it was before the pandemic. 

The first graph below shows outstanding credit card debt fell during the pandemic as the economy cratered. However, after multiple stimulus checks and broad-based economic recovery, consumer confidence rose, and with it, credit card balances surged.

The current trend is steeper than the pre-pandemic trend. Some may be a catch-up, but the current rate is unsustainable. Consequently, borrowing will likely slow down to its pre-pandemic trend or even below it as consumers deal with higher credit card balances and 20+% interest rates on the debt.

The second graph shows that since 2022, credit card balances have grown faster than our incomes. Like the first graph, the credit usage versus income trend is unsustainable, especially with current interest rates.

With many consumers maxing out their credit cards, is it any wonder buy-now-pay-later loans (BNPL) are increasing rapidly?

Insider Intelligence believes that 79 million Americans, or a quarter of those over 18 years old, use BNPL. Lending Tree claims that “nearly 1 in 3 consumers (31%) say they’re at least considering using a buy now, pay later (BNPL) loan this month.”More tellingaccording to their survey, only 52% of those asked are confident they can pay off their BNPL loan without missing a payment!

Wage Growth

Wages have been growing above trend since the pandemic. Since 2022, the average annual growth in compensation has been 6.28%. Higher incomes support more consumption, but higher prices reduce the amount of goods or services one can buy. Over the same period, real compensation has grown by less than half a percent annually. The average real compensation growth was 2.30% during the three years before the pandemic.

In other words, compensation is just keeping up with inflation instead of outpacing it and providing consumers with the ability to consume, save, or pay down debt.

It’s All About Employment

The unemployment rate is 3.9%, up slightly from recent lows but still among the lowest rates in the last seventy-five years.

The uptick in credit card usage, decline in savings, and the savings rate argue that consumers are slowly running out of room to keep consuming at their current pace.

However, the most significant means by which we consume is income. If the unemployment rate stays low, consumption may moderate. But, if the recent uptick in unemployment continues, a recession is extremely likely, as we have seen every time it turned higher.

It’s not just those losing jobs that consume less. Of greater impact is a loss of confidence by those employed when they see friends or neighbors being laid off.   

Accordingly, the labor market is probably the most important leading indicator of consumption and of the ability of the Bougie Broke to continue to be Bougie instead of flat-out broke!

Summary

There are always consumers living above their means. This is often harmless until their means decline or disappear. The Bougie Broke meme and the ability social media gives consumers to flaunt their “wealth” is a new medium for an age-old message.

Diving into the data, it argues that consumption will likely slow in the coming months. Such would allow some consumers to save and whittle down their debt. That situation would be healthy and unlikely to cause a recession.

The potential for the unemployment rate to continue higher is of much greater concern. The combination of a higher unemployment rate and strapped consumers could accentuate a recession.

The most potent labor market indicator of all is still strongly positive

 - by New Deal democrat


On Monday I examined some series from last Friday’s Household survey in the jobs report, highlighting that they more frequently than not indicated a recession was near or underway. But I concluded by noting that this survey has historically been noisy, and I thought it would be resolved away this time. Specifically, there was strong contrary data from the Establishment survey, backed up by yesterday’s inflation report, to the contrary. Today I’ll examine that, looking at two other series.


Historically, as economic expansions progress and the unemployment rate goes down, average hourly wages for nonsupervisory workers improve at an increasing rate (blue in the graph below). But eventually, inflation (red) picks up and overtakes that wage growth, and a recession occurs shortly thereafter. Not always, as we’ll see in the graph below, but usually:



As you can see, there have been a number of exceptions to the rule, chiefly where inflation outstripped wage growth, but no recession happened anyway. Typically this has occurred because of the entry of so many more people (like women in the 1980s and early 1990s) into the labor force.

And we certainly see that inflation outstripped wages in 2022, not coincidentally when there were several negative quarters of real GDP. But with the decline in gas prices, in 2023 inflation subsided much more sharply than wage growth, and the economy improved more substantially. That has remained the case in the first two months of 2024.

But an even more potent indicator is one I have come to rely on even more: real aggregate payrolls for nonsupervisory workers. Here’s its historical record up until the pandemic:



There’s not a single false positive, nor a single false negative. If YoY aggregate payroll growth is stronger than YoY inflation, you’re in an expansion. If it’s weaker, you’re in a recession. Period.

And here is its record since the pandemic:



Real aggregate nonsurpervisory payrolls are positive, and they got more positive in 2023 compared with 2022. Currently they are 2.6% higher YoY than inflation.

In addition to the YoY comparison, real aggregate nonsupervisory payrolls have always declined, at least slightly, from their expansion peaks before every single recession in the past 50 years except for when the pandemic suddenly shut down the economy:



Not every slight decline means a recession is coming. But if real aggregate payrolls are at a new high, you’re not in a recession, and one isn’t likely to occur in the next 6 months, either.

And in case it isn’t clear from that long term graph, here’s the short term graph of the same thing:



Real aggregate nonsupervisory payrolls made a new all-time high in February. Despite the negative metrics in the Household survey, this is *very* potent evidence that not only are we not in a recession, but one isn’t likely in the immediate future either.
