History

The history of
purchasing power.

Markets measure prices.
History measures what money could actually buy.

Markets rose dramatically over the last five decades.

Affordability didn't always follow.

SPX Terminal exists to visualise that gap.

The breakpoint

When money
changed.

In 1971, the United States ended the convertibility of the dollar into gold. It was a technical monetary decision — but its effects compounded over decades.

The relationship between money creation, asset prices, and everyday affordability began to shift gradually. More slowly at first. Then less slowly.

By 2020, the effects had become difficult to ignore.

Most people could feel it — even if they couldn't explain it.

The effects were gradual. But over time, the relationship between money, assets, and affordability began to change.

The gap between markets and everyday life is what this page documents.

Everyday purchasing power

Money buys less.

The same items. Decades apart. The products stayed roughly the same — the money changed. These numbers aren't alarming statistics. They're things people buy every day.

Real-world affordability

Housing outran
wages.

Home prices and household income both rose since 1990. But not at the same pace. Homes appreciated nearly three times faster than wages — quietly making ownership harder to reach for each new generation.

Markets rose. Affordability fell. Both things happened at the same time.

The gap between these two lines is where the feeling of unaffordability lives.

The liquidity era

When money expands,
prices adjust.

When central banks create more money, that money flows somewhere. Into stocks. Into real estate. Into assets. Prices rise — not always because things became more valuable, but because the money buying them became more abundant.

Understanding this is the difference between a market that doubled and a life that improved.

Internet-native finance

A new kind of
financial culture
emerged.

Younger generations experienced financial crises, inflation, and digital markets simultaneously. They grew up watching institutions fail, assets inflate, and access narrow.

From this environment, a new form of internet-native financial culture evolved — shaped by liquidity, collective attention, speculation, and a certain cultural irreverence toward traditional finance.

SPX6900 reflects this phenomenon. SPX Terminal documents it through data.

01
Financial crises created distrust

2008 showed that financial systems could fail dramatically. It created lasting scepticism toward institutions — and lasting interest in alternatives.

02
Digital markets became accessible

Mobile apps, zero-commission trading, and blockchain technology opened financial participation to billions of people who previously had limited access.

03
Culture and markets converged

SPX6900 reflects a new form of internet-native financial culture shaped by liquidity, internet culture, and collective attention. Its long-term significance is something markets will determine.

Markets measure prices.
Purchasing power
measures reality.

SPX Terminal tracks the gap between what markets say and what life costs.
