And indications from the markets are that the disease is in a late phase, though still short of the final deadly stage characterized by pervasive falls in asset markets, sometimes financial panic, and the onset of recession.

Global Signs of Danger

A key sign of danger, recognizable from historical patterns of how the disease progresses, is the combination of steep speculative temperature falls in some markets, with still-high — and in some cases, soaring — temperatures in other markets. Another sign is some pull-back in the carry trade, featuring, in particular, the uncovered arbitrage between a low (or zero) interest rate, and higher rate currencies. For now, however, this is still booming in some areas of the global market-place.

Specifically, we now observe steep falls in commodity markets (also in commodity currencies and mining equities) which were the original area of the global market-place where the QE-asset price inflation disease attacked (back in 2009–11).

Previously hot real estate markets in emerging market economies (especially China and Brazil) have cooled at least to a moderate extent. Most emerging market currencies — with the key exception of the Chinese yuan — once the darling of the carry traders, are in ugly bear markets. The Shanghai equity market bubble has burst.

Yet in large areas of the high-yield credit markets (including in particular the so-called covenant-lite paper issued by highly leveraged corporations) speculative temperatures remain at scorching levels. Meanwhile, Silicon Valley equities (both in the public and private markets), and private equity funds enjoy fantasy valuations. Ten-year Spanish and Italian government bond yields are hovering below 2 percent, and hot spots in global advanced-economy real estate — whether San Francisco, Sydney, or Vancouver — just seem to get hotter, even though we should qualify these last two observations by noting the slump in the Canadian and Australian dollars. Also, there is tentative evidence that London high-end real estate is weakening somewhat.
