When major retailers cut prices, it indicates consumers can no longer afford goods, leading to demand destruction. This squeezes corporate margins, forcing layoffs to control costs. The resulting job losses further reduce consumer spending, triggering a deflationary spiral across the economy.

A severe energy crisis doesn't just raise all prices. It creates shortages of specific fuels like diesel, halting supply chains. This leads to bizarre deflationary effects, like trucks of perishable goods being sold off at fire-sale prices on the roadside because they can't reach their destination.

Contrary to the Fed's theory of inflationary spirals, businesses cannot pass higher input costs to consumers. Customers are too financially strained. Instead, companies absorb the costs, which squeezes profit margins and forces deflationary actions like layoffs and reduced hours to survive.

While moderately high oil prices are inflationary, extreme prices ($500/bbl) become massively deflationary by destroying demand across the entire economy. This paradox complicates the central bank response, as an initial inflationary shock could morph into a severe recessionary impulse.

Technological innovation should naturally make goods and services cheaper every year. When prices rise instead, it's a sign that central banks are 'stealing' that progress through inflation to fund government spending. Crisis-led deflation is bad; innovation-led deflation is beneficial.

Unlike the 1970s oil crisis, today's energy shocks cause demand destruction because consumers are weaker. In the 70s, people had decades of real wage growth. Today, after decades of wage stagnation, consumers have no financial cushion, forcing them to cut spending immediately when prices rise.

While consumers might see 0% inflation as perfect, economists consider it dangerous because it is perilously close to deflation. Deflation can cripple an economy by encouraging consumers to delay spending and increasing the real value of debt, making it a state to be actively avoided.

Jim Grant argues the Fed, haunted by the Great Depression, wrongly treats all deflation as catastrophic. He differentiates between harmful credit-driven collapses and beneficial, technology-driven price declines, which he calls "progress," suggesting this leads to flawed policy.

A significant red flag for the U.S. economy is the year-over-year decline in real disposable income per capita. This erosion of consumer purchasing power rarely happens outside of a recession and is a deeply concerning indicator for future spending, the economy's primary engine.
