Brexit: Everything You Need To Know, Part III: Shock To Stocks

In just a few days, it’s conceivable that the European Union’s political and economic future could be reshaped by this Thursday’s scheduled UK referendum vote regarding whether Britain should retain membership in, or exit, the EU. Popularly known as ‘Brexit’ – shorthand for Britain Exit—the vote outcome could have far-reaching consequences for not just the British and Eurozone economies, but also for global currency and equity markets in particular.

Over the course of three articles, two of which were published last week, we’re taking a deeper look at what the vote means for all involved. Today’s article describes the affect the vote might have on global and UK stocks. Part I, Brexit: Everything You Need To Know (But Were Afraid To Ask), offered an over view of reasons for the referendum; The second installment, Brexit: Everything You Need To Know, Part II: The FX Effect, considered the consequences either a remain or leave outcome might have on major currencies.

As discussed in our previous article, consensus opinion believes that if the leave faction wins the upcoming Brexit referendum, the pound sterling could see a devaluation of as much as 15-20%. Currency devaluations are often followed by a rise in the country's leading equities index.

This happens because the price of goods in the local currency decreases versus trading partners’ currencies, thereby making exports by local companies more attractive compared to imports of competitive goods. As a result, local company profits rise, which, for publicly traded companies, generally drives up the price of shares.

In the UK, the leading index is the FTSE 100, a stock index of the 100 largest companies—based on market cap—listed on the London stock exchange. Similar to the US’s S&P 500, where companies such as Apple (NASDAQ:AAPL) or Alphabet (NASDAQ:GOOGL) are traded, the FTSE 100 is made up of such high profile companies as Royal Dutch Shell A (LON:RDSa), HSBC (LON:HSBA), and British American Tobacco PLC (LON:BATS), to name a few.

Though the UK's equity market could plummet immediately after the vote if the Leaves win, a currency devaluation might cause it to rise in the medium-term, as a Brexit takes effect. However, some companies will still bear the brunt of the change in, or nullification of, trade agreements. A breakdown by sector better illustrates the possible consequences.

For starters, the repercussions of Brexit on UK companies depends on how long it will take for the UK to renegotiate with the EU and other trade partners, as well as how the transition period might play out. A report by the Atradius Group found that sectors most likely to be hurt by a Brexit include Mineral Fuels, Chemicals, and Manufactured Goods. Companies within these niches all export more than half of their total output to the EU, making them extremely vulnerable should a trade stoppage occur. The Oil & Gas segment, considered a sub-sector of the Chemicals industry, exports 77% of its output to the EU.

Companies which provide services rather than goods—currently about 80% of the UK economy—are also very much at risk. London is now the biggest financial hub in Europe, and it exports about a third of its total services to the EU. Additionally, many EU investment banks have London headquarters, which would have to be moved.

According to the Wall Street Journal :

“In addition to short-term market turmoil and share selloffs, analysts say, a UK exit would trigger one-off restructuring costs for investment banks in London who may have to relocate their London hubs, could sour banks’ loans to pan-European companies which could face new trade restrictions and generally damp demand for credit.”

As a result, bank stocks including France’s Societe Generale (PA:SOGN), Germany’s Deutsche Bank (DE:DBKGn), and even the US’s JP Morgan Chase (NYSE:JPM) could take a hit. Even UK-headquartered commercial lenders such as Royal Bank of Scotland (NYSE:RBS), Barclays (NYSE:BCS) and Lloyds (NYSE:LYG) might see a ‘moderate impact’ notes the Financial Times .

While new trade agreements are being ironed out, it is expected that accords on services will be more difficult to mediate due to their fluidity and intangible characteristics. Thus, services in general—and financial services in particular—are more likely to be frozen out of the EU for a longer period of time; It’s even possible that not all services will eventually gain access to the EU's single market.
