According to the St. Luis Fed, U.S. household wealth has reached a historical high of 535% of the U.S. GDP (see: https://www.zerohedge.com/news/2019-04-16/where-inflation-hiding-asset-prices).
There is a problem, however, with the above data: it reflects some dodgy ways of counting 'household wealth'. For two primary reasons: firstly, it ignores concentration risk arising from wealth inequality, and secondly, it ignores concentration risk arising from households' exposure to property markets. A good measure of liquidity risk controlled allocation of wealth is ownership of liquid equities (note: equities, of course, and are subject to Fed-funded bubble dynamics). The chart below - via https://www.topdowncharts.com/single-post/2019/04/22/Weekly-SP-500-ChartStorm---21-April-2019 shows a pretty dire state of equity markets (the source of returns on asset demand side being swamped over the last decade by shares buybacks and M&As), but it also shows that households did not benefit materially from the equities bubble.
In other words, controlling for liquidity risk, the Fed's meme of historically high household wealth is seriously challenged. And controlling for wealth inequality (distributional features of wealth), it is probably dubious overall.
So here's the chart showing just how absurdly property-dependent (households' home equity valuations in red line, index starting at 100 at the end of the Global Financial Crisis) the Fed 'wealth' figures (blue line, same starting index) are:
In fact, dynamically, rates of growth in household home equity have been far in excess of the rates of growth in other assets since 2012. In that, the dynamics of the current 'sound economy' are identical (and actually more dramatic) to the 2000-2006 bubble: property, property and more property.
