What happened — and what it teaches
Boston's property market entered a turbulent phase in early 1989 as the national savings and loan crisis rippled through regional real estate. Regional banks, scarred by the S&L meltdown, tightened lending standards while uncertainty hung over commercial and residential valuations alike. Participants replaying this 30-month period face the task of navigating a market where the fundamental consensus on property values was being actively rewritten.
Between March 1989 and August 1991, Boston property prices declined from 74.48 to 64.79, a drop of 13.0%. The market carved out a maximum drawdown of 15.2%, with individual monthly moves capped at 2.0%. Six decision points punctuated this descent, two of them flagged as critical moments where positioning choices carried heightened consequence. This was not a single crash but a grinding compression lasting two and a half years.
This replay trains participants to execute process under sustained pressure rather than react to noise. The lesson centers on risk management during extended drawdowns: preserving capital when no clear floor exists and avoiding the behavioral trap of crystallizing losses at the worst moment. By confronting a historical episode where the consensus turned against an entire asset class, participants sharpen judgment about when fundamentals matter more than momentum.
