Former RBI Governor Raghuram Rajan points to a historical pattern preceding every major financial crisis: a U-shape in monetary policy. An extended period of easy money builds up risk, and the subsequent tightening phase triggers the collapse. This framework helps identify periods of heightened systemic vulnerability.

The US is not facing a single issue but a convergence of multiple stressors. Unsustainable fiscal policy, fragile funding markets, geopolitical shifts, energy production issues, and leveraged financial players create a highly volatile environment where one failure could trigger a cascade.

Don't dismiss megatrends like demographics and technology as only long-term concerns. Research from Vanguard's Joe Davis shows these forces account for roughly 60% of quarter-to-quarter changes in per capita GDP growth and earnings yield, making them immediate drivers of the business cycle.

Deteriorating debt fundamentals are a known long-term risk, but markets often remain complacent until a specific political event, like an election or leadership change, acts as a trigger. These upheavals force an immediate re-evaluation of what is sustainable, transforming abstract fiscal worries into concrete, costly market volatility.

Financial history rhymes because the underlying driver—human nature—is constant. Core desires for wealth, recognition, and love, along with the fear of pain and envy of others' success, have remained unchanged for millennia. These emotions will continue to fuel bubbles and crashes, regardless of new technologies or financial instruments.

Dalio argues that the convergence of five historical forces—debt cycles, internal conflict (wealth gaps), shifting world order, acts of nature, and technology—drives major societal changes. Understanding these interconnected cycles provides a clearer long-term perspective than focusing on daily news.

The predictable four-year crypto cycle isn't random. It's explained by two parallel forces: a macro trend tracking global M2 money supply fluctuations, and a micro, commodity-like pattern of supply shocks, speculative bubbles, and subsequent crashes.

The traditional relationship where economic performance dictated political outcomes has flipped. Now, political priorities like tariff policies, reshoring, and populist movements are the primary drivers of economic trends, creating a more unpredictable environment for investors.

Current instability is not unique to one country but part of a global pattern. This mirrors historical "crisis centuries" (like the 17th) where civil wars, plagues, and economic turmoil occurred simultaneously across different civilizations, driven by similar underlying variables.
