Peter Frew is one of a tiny number of people left in the United States who can — entirely on his own, using almost no machinery — make a classic bespoke suit. He can measure you, draw a pattern, cut the fabric and then hand-stitch a suit designed to fit your body perfectly.

Frew spent more than a decade as an apprentice for a remarkable tailor in his native Jamaica. He now sells his suits for about $4,000. Since New York is filled with very rich people who see their suits as an essential uniform, Frew has all the orders he can handle.

Every day at 11 a.m., a few big banks tell the British Bankers' Association what it costs them to borrow. Out of that comes LIBOR — the London Interbank Offered Rate, a dull but vital interest rate that underpins trillions of dollars of transactions globally, from home mortgages and personal credit cards to major corporate lending.
