INTRODUCTION

English translation pending.

CORE DEFINITION

Proposed by the analyst Andrew Lawrence. The pattern is that record-breaking skyscrapers are commissioned during periods of easy credit and peak optimism and are completed just as the cycle turns, so the ribbon-cutting coincides with recession. The core proposition is that such projects are monuments to surplus capital and confidence rather than to current demand. The key qualification is that the sample is tiny and the relationship is suggestive rather than causal, so the index works best as one sentiment reading among many rather than as a forecast.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Bubble watch: flag industries funding grand monuments unrelated to their current function. - Cycle marker: treat landmark completions as a sentiment reading rather than a forecast. - Capital check: ask where the financing came from before reading the project as demand.

anchor

Anchor fast decisions

Towering projects need long lead times, cheap credit and abundant optimism, all of which peak late in an expansion. By the time the building opens, the credit conditions that funded it have tightened and the demand assumptions behind it have usually weakened. The monument therefore records the moment of maximum confidence rather than maximum need, which is why its completion tends to mark the turn rather than the trend.
