In February 2020, SoftBank Group Corp.¡¯s Masayoshi Son visited Indonesia, offering to invest billions of dollars toward the development of a new capital city. Lex Greensill, at the time a favorite of Son¡¯s, was part of the entourage.

SoftBank had invested $1.5 billion (?166 billion) in Greensill¡¯s eponymous finance company, but in a meeting with Indonesian President Joko Widodo, Son introduced Greensill as the ¡°money guy,¡± according to local TV footage.

One year later, the money guy has become a money pit. Greensill Capital collapsed in March in one of the most spectacular financial blowups of recent years, sending shock waves through a Swiss banking giant, two of Japan¡¯s largest firms and a British tycoon¡¯s industrial empire.
