This week, US markets hit a fresh all-time closing high. On Wednesday, the S&P 500 closed at 2,933, beating the record set in October.
Central banks have turned dovish. Growth has held up a little better than expected. Jobs data remains solid.
What’s not to like? No wonder markets are heading skywards again.
Unfortunately, there’s a financial serpent in this bullish paradise.
It takes the form of the US dollar.
This has been an epic year for investors so far
Markets have been in “risk-on” mode all this year. 2019 has
seen just about every asset class enjoy monster rallies, even if it
hasn’t always felt terribly cheerful on this side of the Atlantic, what
with shrieking Brexit headlines everywhere.
According to Bank of America Merrill Lynch, by mid-April,
commodities were up nearly 20%, global stocks by 14%, and junk bonds by
about 7%. That has made it one of the strongest starts to a year on
record.
Fair enough, the year started on a low, following the panic
in the last quarter of 2018. Even so, that’s an impressive start to the
year (though notably 1987 started off in the same way, so let’s not
count our chickens yet).
Anyway, one thing about a “risk-on” market is this – you’d normally expect it to be accompanied by a weaker US dollar.
Why? Firstly, the US dollar is generally viewed as a “safe
haven” asset. When people are feeling exuberant, they sell dollars and
dollar assets to buy riskier assets overseas. So that’s one reason why
the continued strength of the dollar is a little surprising.
Second, a stronger US dollar typically goes hand in hand
with tighter monetary policy. The Federal Reserve has U-turned quite
dramatically this year on interest rates. And yet the dollar has hung on
and in fact stubbornly continued to head higher.
Indeed, this week the US dollar index (a measure of the
strength of the American currency against a basket of the currencies of
its main trading partners) hit its highest point for the year, and it’s
now near a two-year high.
That’s a bit of a worry for the bulls for a third reason –
that is, a strong US dollar effectively means tighter monetary policy
for the entire world. Put simply, everyone needs dollars, so the more
expensive they are, the less money there is for everything else.
We’re already seeing the resulting squeeze having an impact
on the world’s more perennially fragile markets, such as Argentina and
Turkey. And if the dollar stays up here for much longer, the jitters
could spread to emerging economies normally viewed as more resilient.
As Macro Intelligence 2 Partners points out in a recent
commentary, the dollar at this level is “stuck firmly in the middle of
the ‘crisis zone’. A band where historically, dollar strength was
sufficient to trigger the Latam Debt Crisis in the ‘80s, the Asian
crisis in the ‘90s and China’s 2015 devaluation.”
That’s a bit of a worry.
Are we facing a melt-up or a meltdown?
So why has the US dollar been so strong? A lot of it is
simply down to weakness in other currencies. It’s true that the Fed
U-turned at the start of this year. But so has pretty much every other
central bank in the world.
Europe is slowing down. China is warming up to do more
“stimulus”. Japan is – well, Japan. The UK has Brexit to suppress
sterling. Australia’s economy is slowing due to its house price bubble
popping. Sweden has just decided to do more quantitative easing.
In effect, the Fed is losing the war of the “doves”. The US
is hardly enjoying epic economic growth and yet it is still one of the
healthiest-looking economies out there.
With central banks around the world showing no signs of
raising rates, that should be good for asset prices. But the risk is
that a strong dollar not only exerts a pinch on vulnerable countries
with dollar-denominated debt, but also that it starts to squeeze
earnings for big US companies – a big chunk of profits in the S&P
500 derive from overseas sales.
Some are already feeling the pinch – US conglomerate 3M,
maker of Post-It notes, issued a profit warning yesterday, and saw its
share price tumble by more than 10%. Combine a strong dollar with a
weakening global economy and that’s a recipe for a profit squeeze, which
is in turn, bad news for highly-valued share prices.
Now, if I’m writing about this, it’s hardly a big secret.
So it’s quite possible that a nervy Fed will act to curb dollar
strength, or that Donald Trump will get on Twitter and try to talk it
down.
To be clear, if Janet Yellen was running the show right
now, I reckon the Fed would already have stopped quantitative tightening
(QT) and raised hints about another bout of QE. But Yellen is not in
charge any more, and the market has yet to fully believe that Jerome
Powell has its back.
My base case at the moment is that we get the “melt-up
followed by meltdown” scenario, driven mainly by overly loose monetary
policy allowing inflationary pressure to get out of hand. But if the US
dollar doesn’t turn lower soon, we might have to see another big plunge
in the S&P 500 to convince the Fed that it needs to address this.
(By the way, to be clear, I am not calling for Fed
intervention. I like the idea of free markets being able to roam as they
see fit, ideally being informed by economic reality rather than the
volume of printed money available. But this is the way the world
currently works – for the bull case to win out
