The code is full of magic tuple indices: (nth o 0) for loan id, (nth o 1) for amount, and so on. Add:

(defrecord loan (id amount term defaultn)), (defrecord bond (price size turns-left)), (defrecord offer (price size turns-left))
accessors: loan-id, loan-amount, loan-term, loan-default
pattern matching: (match loan [(loan id amount term default) ...])

This alone prevents a large class of AI bugs. Acceptance: the market accessors return record-shaped values (or the records are constructible from them), and the brains stop using nth for tuples.
