TL;DR In the soft market vs. hard market cycle, soft conditions bring abundant capacity, falling premiums, and broader terms that favor buyers, while hard conditions bring rate increases, stricter underwriting, shrinking limits, and leverage that shifts to carriers. The turns are driven by catastrophe losses, combined ratios, investment income, reinsurance costs, capital inflows, and inflation, but in either phase, the strongest lever a broker controls is submission quality: current valuations, complete property schedules, and explained loss history.
