Temasek invested in both the FTX mothership and its U.S. wing in concurrent funding rounds of $400 million each in January of this year. The investment fund is now prepared to write off the entire amount of its investments, according to the report, which cited people familiar with the matter.

The Singaporean state fund has been among the most high profile investors in the crypto industry of late, also backing liquidity provider and market maker Amber Group and non-fungible token investment firm Animoca Brands this year. It will remain to be seen to what extent having to write off $200 million to 300 million on the back of FTX's dramatic collapse will dampen Temasek's appetite for the digital assets industry. Temasek managed $294 billion in assets as of the end of March, according to Bloomberg.
