From Nigeria on the west coast of Africa to the Pacific Ocean, dire is a fair description of events. Boko Haram, the Islamic State and radical Islam have infected several continents. Iraqi forces are attempting to retake Mosul from IS insurgents. If or when they do, installing some measure of governance, stability and the rule of law will be as testing as driving IS from Iraq. Syria and Libya are in flames. The war in Yemen persists. Afghanistan is far from settled. Kashmir remains a potential flash point for India and Pakistan. North Korea’s Kim Jong-un is aggressively increasing his nuclear weapons capacity. And China persists in fortifying tiny specks in the various seas named after it. Meanwhile, Vladimir Putin appears to be riding a wave of (temporary) success. His popularity with his country mates is above 80 percent, admittedly down a bit. But, if accurate, American politicians would be tempted to rent their souls for that approval rating. Putin’s incursion into Ukraine and his annexation of Crimea have led western powers to fear a new cold war may be underway. Putin’s support of Syrian President Bashar al-Assad has saved that regime, and certainly has shifted the balance of the war against the opposition. His aggressive actions towards NATO with Russian aircraft buzzing alliance war ships and reconnaissance aircraft, and the deployment of nuclear capable Iskander missiles to Kaliningrad can only be regarded as provocative and dangerous. The deployment of a small Russian naval task group through the English Channel smacked of the Cold War and the twice-yearly transit from the Northern Fleet in Murmansk of relief units for the Mediterranean Eskadra. The difference was that Russia purposely chose October 21st — the anniversary of one of Britain’s most celebrated days and the Battle of Trafalgar in 1805 — for this transit. And Russian civil defence exercises in Moscow and seeming preparations for nuclear war are likewise unsettling. While many regard Putin as a growing or even the principal threat, it may prove to be an exaggeration. First, Putin has no intention of invading the Baltics or Black Sea members of NATO as he did in Ukraine. It makes no sense to risk a war that could go nuclear. Second, Putin has other means to intimidate and achieve his aims of expanding Russian influence and prestige through propaganda, cyber tactics and deployment and exercising of his military forces. Interestingly, if the American public were polled as to whether it viewed Congress or Putin as the greater threat, one suspects the result would be a close run thing. What then should worry Americans? I argue that America’s financial structure is fragile. But does this worry also apply to Pakistanis? The financial collapse of 2008-2009, the worst since the Great Depression and stock market crash of 1929, was largely caused by an orgy of excessive leverage of debt in the mortgage and housing sectors. In essence, bets were made without any collateral. When it turned out housing prices were not guaranteed to rise forever, the market collapsed. Today, another potential vulnerability looms. This can be categorised as the P/E or price to earnings ratio that has become hugely inflated. Price refers to the price of the stock. Earnings refer to the profit companies make. Historically, the major stock exchanges operated on P/E’s ranging between 12-16 to 1, meaning that shares sold at that multiple of earnings. Today, the Dow Jones Industrial Average currently fluctuating north of 18,000 has P/E of about 20 to 1. The NASDAQ exchange now about 2500 consisting of higher technology stocks, has a current P/E of about 25 to 1. With interest rates set at record low levels and some negatively — meaning that banks that keep excess cash on hand must pay a fee — stock markets offer the best returns. Interests rates cannot remain at these levels forever. And the World Bank calculates the total global debt has soared to between $150-200 trillion. It is difficult if not impossible to calculate global total net worth or value. Assuming the United States’ total net worth is around $100 trillion, and that is about 1/3 of the rest of the world, $300 trillion total value against $200 trillion of debt seems sustainable. The reality is however that this debt is uneven. So what happens when interest rates go up? How that debt will be serviced is critical. When this happen, the chances that P/Es will revert to historical averages is high meaning that the value of equities markets could decline by 15, 20 or 25 percent. For most investors, that would be extremely damaging. Of course, markets recover. After the 1987 and 2008 meltdowns, markets rebounded. That was not entirely true during the Great Depression. Pakistan, along with other developing economies, would likewise be affected. However the P/Es of the Karachi Stock Exchange (KSE), using the top 30, is not quite so out of balance. The lowest P/E, as of October 25, was K-Electric at 7.2. The two highest were Searle at 35.6 and Honda Atlas at 24.7. Of course, the KSE is vastly different from US markets in size and structure. Yet, all markets are linked financially and through a globalised world that makes insulating a specific country difficult if not impossible. And Pakistan has other more looming dangers and threats that are well understood. The suicide bombing earlier this week of a police training academy that killed at least four dozen and wounded several times that amount is a tragic reminder that terror and radicalism persist. The electricity crisis has not been resolved and access to water remains critical. In many ways, the competence of government has never been complete. Hence, if P/Es in the US were a warning indicator, Pakistan would suffer from secondary and tertiary effects — none good. The conclusion is that while Putin is seen as a threat, beware P/E. A market meltdown is not inevitable. But it will be exceedingly painful. The writer is UPI’s Arnaud de Borchgrave Distinguished Columnist.
