Indexmesh Hub

When indices move together, diversification is only a rumour.

We study how global equity and bond benchmarks travel in tandem — and when they stop — for desks that need a clear correlation brief, not another chart pack.

What we deliver

A written correlation brief you can take into committee.

Indexmesh Hub prepares global index correlation analysis for portfolio managers, family offices, and research desks in the City. Each engagement maps rolling relationships across major equity, rates, and regional benchmarks, then explains what those linkages mean for concentration risk in a live book.

You leave with a dated memorandum, annotated correlation matrices for the windows you care about, and a short walk-through of regime shifts — not a login to software.

How desks use us

Stress periods, not fair-weather averages.

Clients commission us when average pairwise correlations look calm but drawdown weeks tell another story. We isolate crisis windows, currency overlays, and sector index clusters so the committee can see where geographic labels still buy true independence — and where they do not.

What clients say after a briefing

Their rolling-window note on FTSE 100 versus Nikkei 225 during the 2022 rates shock changed how we sized the Asia sleeve. The write-up was dense — usefully so — and took a full afternoon to absorb.

We asked for a diversification review ahead of a trustee meeting. Indexmesh Hub showed that our “regional mix” was effectively one US-tech factor. Mild caveat: they refused to soften that conclusion for the slide deck.
