This time it is JP Morgan. From today's Financial Times:
The US electricity regulator has subpoenaed JPMorgan Chase twice in the past three months as it investigates whether the bank manipulated power markets in California and the Midwest region, court filings showed.
The Federal Energy Regulatory Commission revealed the probe in court papers filed on Monday that said the bank’s bidding practices may have inflated electricity costs by at least $73m.
What? Only $73 million? For JP Morgan, it is hardly worth getting out of bed.
