Land-Credit Feedback Loop

5 min read

Summary

The Land-Credit Feedback Loop (also called the “property-credit nexus” or “financialisation of land”) describes the post-1970s structural mechanism by which bank credit and land prices mutually reinforce each other. Rising land prices enable more bank lending (against rising collateral); more bank lending drives more demand for land; higher demand raises prices further. This self-reinforcing cycle — absent during the Bretton Woods / post-war capital control era — emerged when financial deregulation allowed banks to switch from business lending to mortgage lending. Ryan-Collins, Lloyd, and Macfarlane (2017) argue it is the key mechanism explaining why house prices have outpaced incomes and GDP since the 1970s, and why financial crises are now longer and deeper than standard business cycles.

Mechanism

Stage 1: Deregulation Unlocks the Loop

  • Pre-1970s: Banks primarily lent to businesses for productive investment; property lending was regulated and limited
  • Post-1970s: Deregulation allows banks to shift dramatically toward mortgage/property lending
  • Land becomes the dominant form of bank collateral in modern economies
  • Regulatory incentives (Basel risk weights) further favor property lending over business lending [Ryan-Collins Ch.1, p.13]

Stage 2: The Self-Reinforcing Cycle

  1. Banks lend against rising land collateral
  2. Borrowers use credit to bid for land → prices rise
  3. Rising prices increase collateral value → banks lend more
  4. More lending → more demand → prices rise further
  5. Cycle continues until either: (a) borrowers can’t service debt at current rates, or (b) land prices stop rising (removing the expected return that justified prices)
  6. When prices stop rising → they fall (no equilibrium plateau — overpricing must correct)

Stage 3: The Bust

  • Borrowers default → banks hold overvalued collateral
  • Banks must choose: write down (take losses) or hold (freeze credit for years/decades)
  • Japan 1990s: chose to hold → “lost decade” extended to two decades
  • 2008: “creative” destruction of mortgage-backed securities accelerated the reckoning

Evidence: UK Land Prices vs. House Prices vs. Credit

  • UK land prices (real, since WWII): +1,500% (15x)
  • UK house prices (real, since WWII): +500% (5x)
  • Land price volatility dwarfs house price volatility — three major boom-bust cycles (1970s, late 1980s, 2000s) correspond exactly to credit expansions [Ryan-Collins Ch.1, Figure 1.1]
  • House price volatility is “primarily driven by land values” — construction costs move slowly; land prices are the swing factor

What Makes Land Different from Other Collateral

  • Supply of land is fixed (cannot produce more) → rising demand must be met by rising prices
  • Land cannot depreciate (unlike buildings, machines, inventory)
  • Land does not respond to rising prices by increasing supply (unlike other commodities)
  • This means: unlike standard collateral (inventory, equipment), land never triggers the corrective supply response that equilibrates other markets
  • Result: a self-reinforcing loop with no natural brake except debt-service limits

Connection to the 18.6-Year Cycle

The Land-Credit Feedback Loop is the modern credit mechanism that powers the broader 18.6-year real estate cycle:

  • The Georgist/Hoyt cycle describes the land speculation pattern (18-year average)
  • The Loop describes the amplifier — why post-1970 cycles have become more extreme
  • Gaffney’s Element 6 (“Lending for overpriced land weakens banks”) describes the same mechanism [Source: gaffney-role-of-land-markets-2009.pdf]
  • Foldvary’s Austrian component (credit expansion distorting rates) is the Loop’s monetary analog

Policy Implications

Ryan-Collins et al. propose multiple reforms to break the loop:

  1. Land Value Tax — imposes annual carrying costs on land, removing speculative buy-and-hold incentive
  2. Banking regulation — limit banks’ ability to use land as collateral; require higher capital against mortgage lending
  3. Planning reform — reduce speculation by making development more predictable
  4. National accounting reform — separately track land values from building values to make the loop visible
  5. Ownership reform — expand community land trusts, public ownership

PSE Relevance

Phil Anderson’s framework implicitly relies on this loop — his observation that the “winners curse phase” sees land being financed by ever-more-leveraged credit directly maps to this mechanism. The PSE Clock’s “afternoon” phases (3pm–6pm in the current cycle reading) correspond to the loop running at maximum intensity before collapse.

Notable Quotes

“The last few decades have seen an extraordinary growth in real-estate related credit, in particularly for mortgage lending: what we call the ‘financialisation’ of land. The chapter argues that the move towards home ownership as the preferred form of tenure and the liberalization of the banking sector have led to the emergence of a feedback cycle between land and credit that has come to dominate modern economies.” — Ryan-Collins et al. [Ch.1, p.15]

“Capitalist economies are characterized by a land-credit ‘cycle’, which may be longer and deeper than the standard economics’ textbook ‘business-cycle’.” — Ryan-Collins et al., citing Borio (2014)

“Rapid rises in real-estate credit lead to increased financial fragility and are strong predictors of financial crises and long-lasting recessions.” — Ryan-Collins et al. [Ch.1, p.13]
