The Brexit Effect: The Signals Amidst The Noise by Aswath Damodaran

There are few events that catch markets by complete surprise but the decision by British voters to leave the EU comes close. As markets struggle to adjust to the aftermath, analysts and experts are looking backward, likening the event to past crises and modeling their responses accordingly. There are some who see the seeds of a market meltdown, and believe that it is time to cash out of the market. There are others who argue that not only will markets bounce back but that it is a buying opportunity. Not finding much clarity in these arguments and suspicious of bias on both sides, I decided to open up my crisis survival kit, last in use in August 2015, in the midst of another market meltdown.

The Pricing Effect

I am sure that you have been bombarded with news stories about how the market has reacted to the Brexit vote and I won’t bore you with the gory details. Suffice to say that, for the most part, it has followed the crisis rule book: Government bond rates in developed market currencies (the US, Germany, Japan and even the UK) have dropped, gold prices have risen, the price of risk has increased and equity markets have declined. The picture below captures the fallout of the vote:

While most of the reactions are not surprising, there are some interesting aspects worth emphasizing.

  1. Currency Wars: If this is a battle, the British Pound is on the front lines and taking heavy fire, down close to 10% over the last week against the US dollar and approaching three-decade lows, with the Euro seeing collateral damage against the US dollar and the Japanese Yen.
  2. Old EU, New EU and the Rest of the World : The damage is greatest in the EU, but even within the EU, it is the old EU countries (primarily West European, that joined the EU prior to 2000) that have borne the biggest pain, with sovereign CDS spreads rising and stock prices falling the most. The new EU countries (mostly East European) have been hurt less than Britain’s other trading partners (US, Australia and Canada) and the damage has been muted in emerging markets. At least for the moment, this is more a European crisis first than a global one.
  3. Banking Problems? Though I have seen news stories suggesting that financial service companies are being hurt more than the rest of the market by Brexit and that smaller companies are feeling the pain more than larger ones, the evidence is not there for either proposition at the global level. At more localized levels, it is entirely possible that it does exist, especially in the UK, where the big banks (RBS, Barclays) have dropped by 30% or more and mid-cap stocks have done far worse than their  large-cap counterparts.

[drizzle]While I did stop the assessment as of Friday (6/24), the first two days of this trading week have continued to be volatile, with a big down day on Monday (6/27) followed by an up day on Tuesday (6/28), with more surprises to come over the next few days.

The Value Effect

As markets make their moves, the advice that is being offered is contradictory. At one end of the spectrum, some are suggesting that Brexit could trigger a financial crisis similar to 2008, pulling markets further down and the global economy into a recession, and that investors should therefore reduce or eliminate their equity exposures and batten down the hatches. At the other end are those who feel that this is much ado about nothing, that Brexit will not happen or that the UK will renegotiate new terms to live with the EU and that investors should view the market drops as buying opportunities. Given how badly expert advice served us during the run-up to Brexit, I am loath to trust either side and decided to go back to basics to understand how the value of stocks could be affected by the event and perhaps pass judgment on whether the pricing effect is under or overstated. The value of stocks collectively can be written as a function of three key inputs: the cash flows from existing investment, the expected growth in earnings and cash flows and the required return on stocks (composed of a risk free rate and a price for risk). The following figure looks at the possible ways in which Brexit can affect value:

Brexit Effect

Embedded in this picture are the most extreme arguments.  Those who believe that Brexit is Lehman-like are arguing that it will lead to systemic shocks that will lower global growth (not just growth in the UK and the EU) and increase the price of risk. In this story, these shocks will come from banking problems spilling over into the rest of the economy or an unraveling of the EU.  Those who believe that Brexit’s effects are more benign are making a case that while it may reduce UK or even EU growth in the short term, the effects of global growth are likely to be small and/or not persistent and that the risk effect will dissipate once investors feel more reassured.

I see the truth as falling somewhere in the middle.  I think that doomsayers who see this as another Lehman have to provide more tangible evidence of systemic risks that come from Brexit. At least at the moment, while UK banks are being hard hit, there is little evidence of the capital crises and market breakdowns that characterized 2008. It is true that Brexit may open the door to the unraveling of the EU, a bad sign given the size of that market but buffered by the fact that growth has been non-existent in the EU for much of the last six years. If the European experiment hits a wall, it accelerate the shift towards Asia that is already occurring in the global economy. I also think that those who believe that is just another tempest in a teapot are too sanguine. The UK may be only the fifth largest economy in the world but it has a punch that exceeds its weight because London is one of the world’s financial centers. I think that this crisis has potential to slow an already anemic global economy further. If that slowdown happens, the central banks of the world, which already have pushed interest rates to zero and below in many currencies will run out of ammunition. Consequently, I see an extended period of political and economic confusion that will affect global growth and some banks, primarily in the UK and the US, will find their capital stretched by the crisis and their stock prices will react accordingly.

The Bigger Lessons

It is easy to get caught up in the crisis of the moment but there are general lessons that I draw from Brexit that I hope to use in molding my investment strategies.
