On Monday, I divided the world's equity markets into relative market-value weights for some perspective on asset allocation. The global bond market deserves no less, and so I dive into the numbers below. But first, a caveat. Categorizing the planet's supply of fixed-income components is complicated.

For instance, I'm leaving out US munis and collateralized debt the world over. Those are subjective choices, but then again that's par for the course when it comes to setting up rules for investing in bonds. There's relatively little debate when it comes to establishing benchmarks for equities. Bonds, by contrast, are another matter entirely.

Finally, looking at all the pieces in context, here's how the global fixed-income pie is sliced up:
