In short, society couldn’t function as-is without algorithms – and as we lean on them to run more things, it becomes more important for us to learn what they are and what they do.
Algorithms 101
Today’s infographic from Futurism digs into the origins of algorithms, and how they impact our everyday lives.
What is an Algorithm?
An algorithm is a predetermined set of steps for a computer to accomplish a task. It’s basically an instruction manual. And as in life, instruction manuals can be simple (e.g. building an Ikea side table) or extremely complex (e.g. filing a patent). Below is “Sorting Out Sorting” (1981), a timeless primer on sorting methods. It clearly demonstrates the way computers approach sorting vast quantities of information by following a set of instructions.
A famous example of an algorithm is Google’s PageRank, which determines the order in which websites appear in Google’s search rankings. PageRank’s methodology is explained succinctly and effectively in the video below.
By building on a stochastic model called the Markov chain, PageRank revolutionized the way the world accesses information. The power of this algorithm is partially responsible for Google’s ability to control 41% of the online ad market, which is where Alphabet still generates the majority of its revenue.
How Algorithms Influence Society
Social platforms play a substantial role in delivering news and information to us. In fact, an estimated 44% of the U.S. population consumes news via Facebook. The more we rely on social networks to supply us with news, the more algorithms will influence what information we’re exposed to. Since social platforms are designed to serve us customized content, there is a growing concern that we are creating online echo chambers that crowd out opposing views. Algorithms also have a profound influence on our economy. Roughly 50% of the market moves through high frequency trading – the process of using dedicated programs to make automated trading decisions to place orders. Large portions of our economy are now managed with very little human intervention. In recent years, progress in the field of artificial intelligence has generated an abundance of interest and excitement. Deep learning (a technique for implementing machine learning) is making all kinds of machine-assisted tasks possible. Preventive healthcare, driverless vehicles, drug discovery, bioinformatics, and hyper-customized recommendations on shopping websites are all here today or coming down the pipeline.
Deep Learning
The remarkable thing about deep learning is that it goes beyond what any human can program a computer to do. Programmers have instead used a learning algorithm – fueled by terabytes of data – to train it to perform complex tasks. The computer essentially figures out for itself how to recognize the desired objects, text, or actions. Breakthroughs like this are the reason AI startups are now receiving billions of dollars of funding.
The Algorithmic Economy
The potential upside for technology providers are enormous, particularly if proprietary processes work on a global scale. An era where “things” will communicate autonomously and take actions without human intervention is sure to profoundly impact our society. The big question is, what will we do once computers and algorithms are taking care of business?
on But fast forward to the end of last week, and SVB was shuttered by regulators after a panic-induced bank run. So, how exactly did this happen? We dig in below.
Road to a Bank Run
SVB and its customers generally thrived during the low interest rate era, but as rates rose, SVB found itself more exposed to risk than a typical bank. Even so, at the end of 2022, the bank’s balance sheet showed no cause for alarm.
As well, the bank was viewed positively in a number of places. Most Wall Street analyst ratings were overwhelmingly positive on the bank’s stock, and Forbes had just added the bank to its Financial All-Stars list. Outward signs of trouble emerged on Wednesday, March 8th, when SVB surprised investors with news that the bank needed to raise more than $2 billion to shore up its balance sheet. The reaction from prominent venture capitalists was not positive, with Coatue Management, Union Square Ventures, and Peter Thiel’s Founders Fund moving to limit exposure to the 40-year-old bank. The influence of these firms is believed to have added fuel to the fire, and a bank run ensued. Also influencing decision making was the fact that SVB had the highest percentage of uninsured domestic deposits of all big banks. These totaled nearly $152 billion, or about 97% of all deposits. By the end of the day, customers had tried to withdraw $42 billion in deposits.
What Triggered the SVB Collapse?
While the collapse of SVB took place over the course of 44 hours, its roots trace back to the early pandemic years. In 2021, U.S. venture capital-backed companies raised a record $330 billion—double the amount seen in 2020. At the time, interest rates were at rock-bottom levels to help buoy the economy. Matt Levine sums up the situation well: “When interest rates are low everywhere, a dollar in 20 years is about as good as a dollar today, so a startup whose business model is “we will lose money for a decade building artificial intelligence, and then rake in lots of money in the far future” sounds pretty good. When interest rates are higher, a dollar today is better than a dollar tomorrow, so investors want cash flows. When interest rates were low for a long time, and suddenly become high, all the money that was rushing to your customers is suddenly cut off.” Source: Pitchbook Why is this important? During this time, SVB received billions of dollars from these venture-backed clients. In one year alone, their deposits increased 100%. They took these funds and invested them in longer-term bonds. As a result, this created a dangerous trap as the company expected rates would remain low. During this time, SVB invested in bonds at the top of the market. As interest rates rose higher and bond prices declined, SVB started taking major losses on their long-term bond holdings.
Losses Fueling a Liquidity Crunch
When SVB reported its fourth quarter results in early 2023, Moody’s Investor Service, a credit rating agency took notice. In early March, it said that SVB was at high risk for a downgrade due to its significant unrealized losses. In response, SVB looked to sell $2 billion of its investments at a loss to help boost liquidity for its struggling balance sheet. Soon, more hedge funds and venture investors realized SVB could be on thin ice. Depositors withdrew funds in droves, spurring a liquidity squeeze and prompting California regulators and the FDIC to step in and shut down the bank.
What Happens Now?
While much of SVB’s activity was focused on the tech sector, the bank’s shocking collapse has rattled a financial sector that is already on edge.
The four biggest U.S. banks lost a combined $52 billion the day before the SVB collapse. On Friday, other banking stocks saw double-digit drops, including Signature Bank (-23%), First Republic (-15%), and Silvergate Capital (-11%).

When the dust settles, it’s hard to predict the ripple effects that will emerge from this dramatic event. For investors, the Secretary of the Treasury Janet Yellen announced confidence in the banking system remaining resilient, noting that regulators have the proper tools in response to the issue.
But others have seen trouble brewing as far back as 2020 (or earlier) when commercial banking assets were skyrocketing and banks were buying bonds when rates were low.
