This trust loss damages the perceived fairness of ratings. Ratings are key signals in bond markets. They help investors judge risk. But a broken rating process ruins that signal. Investors then avoid securities that need those ratings. Risk-averse groups like pension funds and insurers are especially affected. They must hold top-rated assets by law. After the 2007-2009 crisis, agencies overstated product quality. That caused a loss of credibility. It led to laws like the Dodd-Frank Act. Regulators also reduced their use of ratings. The system is fragile because a few agencies control most ratings. These ratings are built into financial rules. This makes distrust spread quickly. The real damage is not just reputation. It is that markets no longer see ratings as true risk summaries. This raises transaction costs. It lowers liquidity in rated bonds. It pushes markets toward other risk tools.
