The Weekly Fix: Bond Boon for Banks; Dr. Copper Gets a Cold

Welcome to the Weekly Fix! I’m cross-asset reporter Katherine Greifeld, and I’ll be guiding you through this week in fixed-income markets while Emily Barrett takes a well-deserved vacation.

It’s officially earnings season, and the big banks kicked it off with a bang. Second-quarter reports were expected to be anything from confusing to shocking for financials. One thing quickly became crystal-clear: it’s boom-time for bond traders. A flurry of debt deals against a choppy market backdrop boosted Citigroup Inc.’s fixed-income, currencies and commodities trading revenue by 89% last quarter, while JPMorgan Chase & Co. posted an awe-inspiring 120% gain versus a year ago. Goldman Sachs Group Inc. took the crown with a 149% surge, shattering estimates.
