SoftBank invested in the Swiss bank’s $7.5bn range of supply-chain finance funds. SoftBank has quietly poured more than $500m into Credit Suisse investment funds for exchange of big bets on the debt of struggling start-ups backed by the Japanese technology conglomerate’s Vision Fund.

The arrangement has allowed SoftBank effectively to provide financial assistance to other Vision Fund companies by paying their suppliers upfront but through a fund commingled with other investors and financing other companies.

In October, the car subscription company’s founder and chief executive resigned shortly after announcing plans to cut 40 per cent of its workforce. Audited accounts for both funds show they had no exposure to Fair at the end of that month, suggesting that they only began financing the company after its difficulties came to the fore.

Clients have withdrawn more than $1.5bn from these supply-chain finance funds this year, after a string of Greensill Capital’s clients defaulted on their debts in high-profile corporate collapses and accounting scandals, such as former FTSE 100 company NMC Health. Credit Suisse has told investors that a group of insurers and Greensill itself are covering losses in the funds.
