Tallest Building Indicator

4 min read

Summary

The Tallest Building Indicator is the observation — central to PSE’s cycle framework — that each successive real estate cycle peak tends to bring about the biggest and grandest construction projects ever seen, with the property market peaking around the time a new record for the tallest building in the world is announced or completed. It is one of several “record-breaking” signals (alongside IPO Mania and NYSE Margin Debt extremes) that PSE uses to confirm the Winner’s Curse Phase is intensifying. The indicator is not original to PSE — it is widely known in cycle literature as the “Skyscraper Index” (originally popularized by Andrew Lawrence of Barclays Capital in 1999) — but PSE integrates it into the 18.6-year land cycle framework as a reliable qualitative peak-proximity marker.

Core Claims

  • 2026-06-16-gann-17-portfolio-update (2026-06-16): “The end of each successive real estate cycle tends to bring about the biggest and grandest construction projects ever seen. The property market tends to peak around the time you see or hear about a new record for the tallest building in the world.” — Phil Anderson — confidence: high
  • 2026-06-16-gann-17-portfolio-update (2026-06-16): Historical examples cited: Empire State Building announced 1929 (ahead of the 1930s crash), Burj Khalifa completed 2004 (ahead of the 2007-2008 crash). The next record: Jeddah Tower in Saudi Arabia, scheduled for completion in 2028, with construction resuming in 2025 after a lengthy pause. — Phil Anderson — confidence: high

Mechanism / How It Works

The indicator works because record-breaking construction projects require three late-cycle conditions to converge simultaneously:

  1. Cheap and plentiful credit — only available when financial conditions are extremely loose (see Financial Conditions). The financing for a $20B+ mega-project is only viable when lenders are flush and risk appetite is maximal.
  2. Land prices at cycle peaks — the residual land value at prime sites is high enough to justify record-breaking density. The economic logic only pencils out at the top of the land price cycle.
  3. Hubris and euphoria — developers, governments, and financiers collectively believe the good times will continue. The decision to break ground on a record-breaking tower is, by definition, a maximum-conviction bet on the cycle continuing.

The lag between announcement and completion means the indicator often fires before the cycle turns — the Empire State Building was announced in 1929 but completed in 1931, after the crash had already begun. Similarly, the Burj Khalifa’s construction began in 2004 and completed in 2010, bracketing the 2007-2008 peak. The Jeddah Tower’s 2028 target date is consistent with PSE’s 2026-2027 cycle-peak window, with completion likely coming after the cycle has turned.

Applications

  • Cycle-phase confirmation. The announcement or resumption of a record-breaking construction project is a high-confidence late-cycle marker. The 2025 resumption of Jeddah Tower construction is read by PSE as confirming the current cycle is in its final phase.
  • Lead-time awareness. The indicator fires at announcement, not completion. By the time the building opens, the cycle has typically already turned. The Jeddah Tower’s 2028 completion target should not be mistaken for the peak date — the peak comes first.
  • Cross-reference with other record signals. PSE stacks the tallest-building signal with IPO Mania (SpaceX as “largest IPO ever”) and NYSE Margin Debt (margin/M2 at 2000/2008 levels) to confirm the Winner’s Curse Phase is intensifying.

Contradictions & Open Questions

  • The Skyscraper Index has false positives — not every record-breaking building coincides with a major cycle peak. The indicator is qualitative, not mechanistic.
  • The Jeddah Tower’s construction timeline has been uncertain (paused for years). Whether the 2025 resumption is a true cycle signal or simply the resolution of a funding gap is debatable.
  • Some cycle researchers argue the indicator is a coincident signal (it marks the peak) rather than a leading signal (it predicts it). PSE’s framing — “the property market tends to peak around the time” — is deliberately ambiguous on timing.
