Massive investment requires issuing assets (bonds, equity), creating supply pressure that pushes prices down. The resulting spending stimulates the real economy, but this happens with a lag. Investors are in the painful phase where supply is high but growth benefits haven't yet materialized.

German defense firm Rheinmetall's market cap surged from $5B to $80B post-Ukraine invasion, mirroring the explosive growth of AI companies. This highlights how major geopolitical shifts can act as powerful, unexpected catalysts for traditional industries, creating immense value for well-positioned incumbents.

During the 1720s South Sea Bubble, hundreds of speculative companies emerged with no revenue or clear business plans, mirroring the 2020-2021 SPAC boom. One notorious company was pitched for an "undertaking of great advantage, but nobody knows what it is." This highlights that financial vehicles designed to capitalize on market euphoria are not new.

Germany's modern economic problems are rooted in complacency born from past success. Many of its largest firms (Siemens, Bosch) are 19th-century giants that survived two world wars. This fostered a belief that the system was invincible and required no modernization, stifling innovation and startup culture.

In an act of financial warfare, post-war Germany sold its vast silver reserves to adopt the gold standard, intentionally harming France’s bimetallic system. This collapsed silver prices, sparking a global scramble for gold. The resulting shortage of the world's primary safe asset caused a severe credit crunch and a two-decade-long deflationary spiral.

The creation of the Bank of England and John Law's monetary schemes were not academic exercises. They were desperate measures to solve the massive national debts accumulated by England and France from decades of war, showing how fiscal crisis is a powerful catalyst for financial innovation.

After a deep equity bear market, European savers sought alternatives to low-yielding government bonds. They poured capital into higher-risk global bonds, especially for railroads, creating the conditions for the 1873 crisis. This illustrates how past trauma can shape future risk appetite and create new bubbles in seemingly 'safer' asset classes.

For 25 years, public markets were mainly for VC exits. AI's immense cash requirements, which exceed private market capabilities, are forcing a return to the market's 19th-century role: funneling public savings into massive, transformative projects, much like the financing of railroads.

Bubbles have a paradoxical benefit. While they cause immense financial pain for investors caught in the crash, the frenzied capital allocation during the boom often funds transformative infrastructure. The railroad and dot-com bubbles, for example, left behind the national rail network and the fiber-optic backbone of the modern internet.
