The top of the capital markets pecking order includes not just banks and asset managers, but stock-exchange companies. Quiet and unassuming compared with the traditional masters of the universe, they are no less powerful. Nowhere is this more apparent than Japan.

First off, stock-exchange companies operate many of the indexes that increasingly drive global capital flows. London Stock Exchange Group Plc, for instance, owns and manages the UK’s FTSE gauges alongside a suite of other benchmarks under the Russell brand. While the Japanese exchange’s best-known index is owned by local newspaper group Nikkei Inc, it has the more useful market cap-weighted Topix, which is tracked by over ¥83 trillion of assets ($750 billion).

Second, there’s clearing. Regulation designed to create more transparency and reduce systemic risk has routed trading activity away from opaque over-the-counter markets managed by banks and into clearinghouses, most of which are owned by stock exchange companies. Japan’s primary clearinghouse – Japan Securities Clearing Corporation (JSCC) – is a subsidiary of Japan Exchange Group Inc, operator of the Tokyo Stock Exchange. It currently clears around 70% of yen interest-rate swaps globally and, as yen-based activity ramps up with changes to monetary policy imminent, JSCC’s role in global markets is sure to be enhanced.
