Two weeks ago Bank of America caused a stir when it calculated that central banks (mostly the ECB & BoJ) have bought $1 trillion of financial assets just in the first four months of 2017, which amounts to $3.6 trillion annualized, "the largest CB buying on record."
BofA's Michael Hartnett noted that supersized central bank intervention which he dubbed a "liquidity supernova" is "the best explanation why global stocks & bonds both annualizing double-digit gains YTD despite Trump, Le Pen, China, macro..."
Today we showed just what central bank buying looks like in practical terms when we demonstrated that the Swiss national Bank had purchased a record $17 billion in US equities in just the first quarter, bringing its total US equity long holdings to an all time high above $80 billion...
... in the process soaking up nearly 4 million AAPL shares in the first 3 months of the year.
On the surface, these sums appear vast; however in the latest weekly report by Deutsche's Dominic Konstam, the credit strategist finds something even more troubling: $1 trillion in central bank liquidity YTD - or roughly $250 billion per month - is not enough.
The reason is two-fold: on one hand there is the stock of existing central bank assets that keeps growing at an exponential pace, which implies that central banks have to monetize ever more assets just to keep the system from becoming unstable, or "running to stand still"; on the other hand, offsetting the "organic" expansion of central bank balance sheets is the decline in FX reserves among liquidity managers, the most famous recent episode of which is China's $1+ trillion drop in reserves which started in mid-2014 and has yet to conclude. Recall that global liquidity is defined in dollar terms "as the sum of all FX reserves, the fed’s balance sheet and the central bank balance sheets of the Eurozone, Japan, UK, China, India, Russia, Saudi, South Africa and Brazil."
So what happens when in addition to central bank liquidity one adds various other global liquidity components? Here is Konstam's troubling discovery:
Having accelerated for four straight quarters from 2015q4 to a local peak of +5.0 percent in 20167q4, q1 saw the first slowing to a year over year growth rate of just 2.23 percent. In absolute terms it was $29.5 trillion, almost unchanged from 2016q3. The main culprit (again) was FX reserves that sharply dropped by almost 1 percent versus a year ago, based on February data.
Worse, the Deutsche Banker forecasts that "the weak patch for global liquidity growth is likely to extend through to 2017q4 where even based on flat FX reserves ahead of ECB or Fed balance sheet changes, the current rate of ex Fed central bank liquidity growth should lift liquidity growth back to slightly over 5 percent year over year."
This is a problem because "5 percent is not a lot at a global level. It doesn’t accommodate faster nominal growth. And as the chart below indicates is consistent with relatively subdued bond yields. In 5y5y US Treasury terms a 3 percent rate seems a little elevated as is and is pretty much discounting liquidity growth closer to 10 percent, a level last seen in 2013."
But the biggest disconnect between liquidity and implied "fair value" is once again to be found in stocks:
Global equities tell a similar story but even more starkly; they appear to be discounting liquidity growth over 10 percent. This is another example of how the equity market seems to be discounting something very different from the bond market.
Why did Konstam make this analysis? Because, as he writes in his intro, "more than ever before in this tightening cycle we would suggest that the Fed faces the most delicate of balancing acts. There seems to be an almost automatic convergence on a June tightening with September also a possibility and then some kind of balance sheet adjustment. The ECB is widely viewed to be not far behind in terms of another taper and the possibility of an eventual depo rate increase (we think 15 bps priced by August 2018) as a quid pro quo for QE extension."
In other words, the market is blissfully ignorant of the threat that imminent global central bank tightening poses on risk assets, a risk neither ETFs, nor algos, nor CTA have considered.
Konstam's conclusion is that there are two outcomes: either asset prices drops, or central banks will ultimately be forced to inject even more liquidity. Here is his take on the former:
There are a couple of ways in which these disconnects can be resolved. But until they are, global central banks need to tread warily. One resolution is of course equities retreat and yields decline, recognizing the dearth of liquidity. Recently we have used broader liquidity indicators in the context of nominal output for the US, Europe, China and OECD in general to demonstrate that there is falling “excess” liquidity that always implies some kind of loss in real output momentum with a lag. This doesn’t necessarily mean outright declines in output growth but it would, for example, be consistent with weaker PMIs and typically puts a ceiling of where longer term yields can rise to. Specifically we find that yield momentum tends to decline implying, specifically for the US that 10s might be capped around the 2 ½ percent level with downside potential closer to 2 percent on a moderate loss of upward yield momentum.
And then the latter, which can be resolved by either QE4 (or more) or a sharp drop in the USD.
Another way we could see resolution would be an accelerated move higher in liquidity. This seems unlikely in terms of positive new accommodation by central banks, absent deterioration in observed growth or inflation. However it is possible if the dollar were to weaken which would reflate the dollar value of existing liquidity but also probably contribute to a faster recovery in FX reserves. The problem is that dollar rate correlation has remained stubbornly tight although as we have argued since Trump’s election, one senses that that correlation is less assured.... Recent weakness in the likes of iron ore, copper and oil are concerning. The weakness that we have seen in DXY, especially reflecting the European currencies, seems more to do with better growth expectations in Europe and relief around France politics. This will help global liquidity at the margin but Europe can ill afford a very strong euro and we think of this as more an idiosyncratic adjustment to the dollar rather than a US policy induced regime shift that sustains higher inflation."
The bottom line, however, boils down to the realization that the marginal benefit of QE is now negative.
Which means that when stocks realize just how insufficient the record $1 trillion in central bank liquidity has become, central banks - which have stepped into every single market correction over the past 7 years with some "liquidity supernova" - will, for the first time since the financial crisis - be out of tools... something Janet Yellen appears to have realized some time ago.
