The LIBOR rate-manipulation scandal

LIBOR was supposed to provide a benchmark for interest rates around the world, but a major scandal eventually raised questions about whether the numbers were being manipulated. Reports began emerging about traders and financial institutions allegedly influencing the rates used to determine how much banks charged one another for borrowing.

As investigations expanded, regulators and financial authorities in several countries began examining the way LIBOR was calculated and the communications surrounding its daily submissions. What initially looked like an obscure technical process suddenly became a much larger issue because LIBOR was tied to an enormous range of financial products and transactions.

The scandal led to investigations, regulatory actions, fines and a broader examination of how one of the world's most important financial benchmarks had been managed. What made it particularly significant was the realization that something as seemingly routine as a daily interest rate could have consequences across global financial markets.
