By now, you’ve probably heard that global supply chains are in a state of disarray.

Here's a simple breakdown of what’s causing it:

1/ There's a lot of talk right now about the global supply chain crisis.

@Business published an article subtitled "Inside the Brutal Realities of Supply Chain Hell”—it's getting serious.

This thread provides my (very) simple framework for understanding the key drivers:
2/ First off, what are the visible impacts of the crisis?

Product delays (good luck getting appliances before 2022), product shortages (see semiconductors), port buildups (fly over LA and you'll see), and rampant freight costs (sorry, retailer margins).

It's pretty bad.
3/ Global supply chains are very complex. We live in a highly-interconnected world.

A butterfly flaps its wings in Shenzhen and impacts when I receive my bike in New York. Ok, maybe not quite, but almost...

So to understand the drivers of the crisis, we need a simple framework.
4/ Let's break down what is happening using an Econ 101 classic: Supply and Demand.

Supply here refers to everything related to manufacturing, production, and transportation.

Demand here refers to everything related to consumption.

I'll walk through each side:
5/ First, demand. This one is pretty simple: it's through the roof.

Consumers are flush and not afraid to spend.

Further, lockdowns and restrictions have meant more spending on goods vs. services.

So you have a ton of demand for goods--those goods need to come from somewhere!
6/ Next, supply. This one is more nuanced.

The major supply drivers I see here:
(1) Factory shutdowns
(2) Port shutdowns
(3) Flight reductions
(4) Container ship challenges

Hitting each one quickly:
7/ COVID Factory Shutdowns

Factories—particularly in Asia—have had a tough time managing and containing outbreaks of COVID.

This leads to delays and bottlenecks in production. If an upstream manufacturer is delayed, that impact cascades downstream and has an extensive impact.
8/ COVID Port Shutdowns

Ports have experienced similar challenges—any have had to shut down or restrict labor to avoid outbreaks.

If ports are closed, products can't flow smoothly through the supply chain.

It's like creating a kink in a hose and watching pressure build.
9/ Flight Reductions

It's news to most people, but about 50% of air cargo flies on passenger flights.

It's a great revenue stream for passenger airlines.

But with travel—especially international travel—reduced by COVID, there was a significant reduction in air cargo capacity.
10/ Container Ship Challenges

The Ever Given clogged the Suez Canal in March, causing a backlog whose impact cascaded through global supply chains.

There aren't enough large container ships to meet all of this demand and containers are in the wrong places at the wrong times.
11/ So looking at all of this through my simplistic framework, here's what I see:

On one end, a structural surge in demand for goods.

On the other end, a number of significant supply challenges and disclocations.

Demand up, supply down.
12/ The net impact: sharp shipping and production price increases, shortages, and massive delays.

For consumers, this means rising prices, as these rising supply chain costs are passed through.

Your holiday shopping may be a whole lot more expensive (and late) this year...
13/ I hope this simple breakdown helps you feel more well-informed about what is happening with the global supply chain crisis.

By the way, if you’re looking for Christmas presents that you can get at a reasonable price, I hear Evergrande has some really nice half-finished apartments on offer at a deep discount…
Looks like a lot of people are flocking to Evergrande offices to take advantage of this limited time opportunity!

THREAD: With #silversqueeze trending on Twitter, it appears that this week's market spectacle may well be in the silver market.

A perfect moment for a thread on the Hunt Brothers and their alleged attempt to corner the silver market...


1/ First, let's set the stage.

The Hunt Brothers - Nelson Bunker Hunt, William Herbert Hunt, and Lamar Hunt - were the sons of Texas tycoon H.L. Hunt.

H.L. Hunt had amassed a billion-dollar fortune in the oil industry.

He died in 1974 and left that fortune to his family.


2/ After H.L.'s passing, the Hunt Brothers had taken over the family holdings and successfully managed to expand the Hunt empire.

By the late 1970s, the family's fortune was estimated to be ~$5 billion.

In the financial world, the Hunt name was as good as gold (or silver!).


3/ But the 1970s were a turbulent time in America.

Following the oil crisis of the early 1970s, the U.S. had entered a period of stagflation - a dire macroeconomic condition characterized by high inflation, low growth, and high unemployment.


4/ The Hunt Brothers - particularly Nelson Bunker and William Herbert - believed that the inflationary environment would persist and destroy the value of their family's holdings.

To hedge this risk, they turned to silver.

They began buying the metal at ~$3 per ounce in 1973.

This is a GREAT argument to pull up when talking to people about minimum wage. Some others nested below


A large number of new jobs being created are minimum to low wage, so looking for a new job generally won’t increase pay.

Raising minimum wage helps things not directly related.

Helps Infant mortality? Yup.

Lowers Suicide? Yup.

Reduce smoking rates? You bet.

It also boosts the local economy! Minimum to low wage earners spend more % of their money, so an increase means more is spent, often in community!

Low paying jobs are often in sectors which would gain from this. More people spending money in your shop makes your business more money! Now you have more profits and increased labor costs are covered.
