Yeah, sure -- (he was short-selling bonds)

"Official figures at the time showed that reserves had only dwindled by 2bn. Overall, the cost of the operation was estimated at 3.3bn.
Mr Soros made 1bn from his position, earning him the nickname "The man who broke the Bank of England"." -- https://www.independent.co.uk/news/business/news/black-wednesday-john-major-norman-lamont-1992-bank-cost-a8460626.html

Soros himself has remarked:

It also caused a chain reaction, which effected Indonesia:

"Nevertheless, few if any foresaw an economic downturn in Indonesia of the rapidity or depth of that triggered by the Thai financial crisis
of mid-1997, much less that it could lead to the collapse of the Soeharto regime."

Which caused serious malnutrition in millions:

"The official figures indicate that poverty in Indonesia increased from 22.5 million (11.3%) in 1996 to 36.5 million (17.9%) in 1998. Food production decreased by 20-30% in some parts of the country. Compared with prices in January 1998, food prices had escalated 1.5- to threefold by August/November 1998 when acute food shortages occurred, especially in urban Java. Coupled with a drop in purchasing power, the higher food prices worsened health, nutritional status and education of children of urban poor and unemployed families."
