How safe are our Japanese investments?
Following the problems in the sub-prime lending market in America and the
runon Northern Rock in the UK, uncertainty has now hit Japan. In the last
7 days Origami Bank has folded, Sumo Bank has gone belly up andBonsai Bank
announced plans to cut some of its branches. Yesterday, it was announced
that Karaoke Bank is up for sale and will likely be going for a song while
today shares in Kamikaze Bank were suspended after they nose-dived.
Furthermore, 500 staff at Karate Bank got the chop and analysts report that
there is something fishy going on at Sushi Bank where it is feared that
staff may get a raw deal.
