BY THE NUMBERS: HERE'S WHAT YOU NEED TO KNOW ABOUT HSBC'S MONEY-LANDERING AND TAX-EVASION SCANDALS

HSBC CEO Stuart Gulliver.

Swiss authorities shocked the markets Wednesday morning when police raided HSBC's Geneva offices.

In an emailed statement to Business Insider, the Swiss prosecutor's office confirmed it was investigating "HSBC Private Bank (Suisse) SA and persons unknown for suspected aggravated money laundering."

HSBC told us: "We have cooperated continuously with the Swiss authorities since first becoming aware of the data theft in 2008 and we continue to cooperate."

But for HSBC, being embroiled in a money-laundering scandal is not new. The bank already settled with US authorities in 2012.

Here's the quick guide about HSBC's money-laundering and tax-evasion scandals, old and new, in numbers.

£1.2 billion — this is how much HSBC was fined in December 2012 for having lax systems that allowed money laundering to occur through the bank.

2 years — Herve Falciani worked in HSBC's IT department between 2006 and 2008.

2008 — the year Falciani became a whistle-blower by handing over HSBC client bank account details to French authorities.

100,000 — HSBC client accounts under scrutiny related to tax evasion and money-laundering investigations.

£78 billion — the accounts' asset total.

2005 to 2007 — years in which the account data stems from.

203 — countries the scrutinised bank accounts come from.

£188 million — taxes and fines recovered by France from Herve Falciani's data leak.

£220 million — Spain's total amount of recovered tax from the whistle-blower.

£135 million — Britain's comparatively small amount of tax recovered from the Falciani leak.

140 — number of journalists from 45 countries to help unearth the secret accounts in Switzerland.
