Highlights When interest rates are ultra-low, central banks have no margin for policy error. A small loosening or tightening has the potential to produce either a stall or catastrophic turbulence. The analogy is flying a plane at high altitude. Bond investors should have a strong preference for U.S. T-bonds over German bunds (currency hedged). Currency investors should prefer the euro over the dollar. For equity investors, valuations do not appear structurally attractive anywhere, once a sufficient equity risk premium is factored in. But a setback in the region of 5-10% could create a tactical entry point. Feature As the ECB Governing Council convenes for its October monetary policy meeting, an experience familiar to pilots1 provides a perfect analogy for central banks' very limited margin for error. Pilots call the experience "flying in coffin corner." Chart of the WeekUnusually High Turbulence For The German 30-Year Bund Next time you're in a plane climbing to 35,000 feet, here's something to think about; or perhaps, not to think about. As the plane gains altitude, its stall speed increases while its upper speed limit simultaneously decreases. For the pilot, this means less and less margin for error (Figure I-1). The plane's stall speed is the minimum speed to generate sufficient lift. At higher altitude, as the air gets thinner, the stall speed increases. Meanwhile, the plane's upper speed limit is set by the speed of sound. Airliners cannot fly too close to the speed of sound because the sonic shockwave produces violent and catastrophic turbulence. At higher altitude, as the air temperature drops, so does the speed of sound. Which means the plane's upper speed limit decreases. By the time the plane has reached the rarefied atmosphere of 35,000 feet, these lower and upper speed limits are barely 25 knots (30mph) apart,2 leaving almost no room for flight data misinterpretation or pilot error.3 Hence, at high altitude pilots morbidly say they are "flying in coffin corner." Analogously, in the rarefied atmosphere of zero or near-zero interest rates, central bank policy is also in coffin corner. When short-term and long-term interest rates approach the zero bound, there is no room for economic data misinterpretation or policy error. A small loosening or tightening of monetary policy has the potential to produce either a stall or catastrophic turbulence (Figure I-2 and Chart of the Week). Figure I-1Flying At High Altitude ##br## Has No Margin For Error Figure I-2Monetary Policy At Ultra-Low Rates ##br##Has No Margin For Error Avoiding A Stall At today's zero or near-zero interest rates in the euro area, a small loosening of monetary policy risks stalling the banking system, and thereby stalling the economy. A bank's core business is simple. Take in deposits, and lend them out at a higher interest rate than the deposit-rate - with the difference in the two defining the bank's net interest margin. A part of the net interest margin is a compensation for the risk of non-performing loans. This should be profit-neutral if correctly priced. The other large part of the net interest margin comes from the interest rate term-structure, as loans tend to be long-term while deposits are short-term. Hence, all else being equal, the bank's profitability suffers as the term-structure flattens. For a while, the bank can protect its profitability by cutting the interest rate paid on short-term deposits to well below the policy rate. However, once the policy rate hits zero, this profit-protection strategy hits a wall - because a negative deposit rate would risk an exodus of deposits into cash or cash-substitutes. Alternatively, the bank could charge a higher rate to borrowers, but this would tighten credit conditions. The third possibility is for the bank to suffer a hit to its already-thin net lending margin, but this would also tighten credit conditions. The pressure on the bank's profitability and share price would increase the cost of equity, making it harder to raise capital (Chart I-2). Given that an insufficient capital buffer is a major constraint to euro area bank lending, this would be a de facto tightening of credit conditions. The paradox is that at the zero bound, the smallest additional monetary loosening - via interest rate cuts or QE - risks stalling euro area bank credit creation (Chart I-3). Thereby it risks stalling economic growth. Chart I-2The ECB's QE Has Hurt Bank Valuations Chart I-3The Interplay Between Bank Profits And Bank Credit Creation Avoiding Violent Turbulence An extended period of ultra-low interest rates, and a commitment to keep them structurally low, has compressed the yields on government bonds pushing up their prices. As competing asset classes, the prices of corporate bonds and equities have also increased. This phenomenon is called the Portfolio Balance Effect. The big problem is that the prices of riskier assets have increased by more than is justified by the portfolio balance effect alone. This distortion is the result of a behavioural finance phenomenon called Mental Accounting Bias. Mental Accounting Bias describes the irrational distinction between the return from an investment's yield and that from its capital growth. The distinction is irrational because the money that comes from yield and the money that comes from capital growth is perfectly fungible.4 Rationally, what should matter is an investment's total return. But psychologically, the distinction between yield and capital is very stark. Fears about self-control cause people to compartmentalise yield as spending money and capital as saving money. Hence, people who want their investments to generate spending money - say, retirees - have an irrational focus on yield. Traditionally, the safe income from cash and government bonds satiates the people who irrationally focus on yield. However, in recent years, central banks' extended experiments with ZIRP, NIRP and QE have forced these yield-focussed investors out of cash and government bonds into risky investments. And just like every distortion, this phenomenon has generated memes to justify the act: 'reach for yield', 'search for yield', and 'there is no alternative' (TINA). But the irrational focus on yield instead of total return has artificially bid up the prices of risky investments. To the point that they no longer offer a sufficient risk premium5 for the very real possibility of substantial losses over a 5-10 year horizon (Chart I-4 and Chart I-5). The unfortunate thing is that as central bankers have little expertise in psychology or behavioural finance, they have been blind to the very dangerous behavioural distortion that their monetary policy experiments have unwittingly unleashed. Chart I-4A Positive Yield On Equities##br## Can Produce A Negative 5-Year Return... Chart I-5...And Even A Negative ##br##10-Year Return The risk is that the smallest monetary tightening could trigger an aggressive unwinding of this behavioural distortion. Recall the violent turbulence in global financial markets at the start of the year after just one 25bps rate hike from the Federal Reserve. Now consider what might happen if the Fed hiked again and the ECB simultaneously announced a rapid tapering of its QE program. How Must The Pilots Fly? In a rarefied atmosphere, pilots have very little margin to alter speed without inducing a stall or violent turbulence. The same applies to central banks today. The ECB has the hardest piloting task. It is becoming difficult to justify the current aggressive pace of QE given the danger of stalling the euro area banking system; and given that the euro area's nominal GDP and nominal wage bill are both growing at a very respectable 3% (Chart I-6). But an abrupt end to the ECB's QE could create violent turbulence in QE-distorted financial markets. Chart I-6What Deflation Threat? Euro Area Nominal GDP And The Wage Bill Growing At 3% Hence, the ECB's best course of action is to hint at a very gradual deceleration of QE to start at some point in the second half of 2017. Turning to developed economy central banks in general, we remind readers of a very powerful observation. Since 2008, no major central bank has been able to hike interest rates by more than 1.75%. And every central bank that has hiked rates has had to start unwinding those hikes within a year, ultimately taking the policy rate to a new all-time low (Chart I-7 and Chart I-8). Chart I-7Since 2008, All Rate Hikes ##br##Have Been Quickly Reversed Chart I-8Will The U.S. Be ##br##Any Different? No Given the turbulence that rate hikes will generate in the financial markets and/or the economy, we fully expect the Federal Reserve to go through exactly the same experience. The important upshot is that global central bank policy through 2017-18 will be considerably less divergent than is discounted. Bond yields could creep higher in the short term. But on a 1-year horizon, bond investors should have a strong preference for U.S. T-bonds over euro area bonds, and especially over German bunds (currency hedged). Over the same horizon, currency investors should prefer the euro over the dollar. For equity investors, valuations do not appear structurally attractive anywhere once a sufficient equity risk premium is factored in. Moreover, the potential for ECB QE-tapering combined with expectations for a Fed rate hike could generate some near-term turbulence. That said, a setback in the region of 5-10% could create an excellent entry point for a 3-month trade.

Last week's long silver/short lead pair trade has bounced sharply. And the short U.K. A-rated corporate bonds trade has achieved its 4% profit target. For any investment, excessive trend following and groupthink can reach a natural point of instability, at which point the established trend is highly likely to break down with or without an external catalyst. An early warning sign is the investment's fractal dimension approaching its natural lower bound. Encouragingly, this trigger has consistently identified countertrend moves of various magnitudes across all asset classes. Chart I-9 * For more details please see the European Investment Strategy Special Report "Fractals, Liquidity & A Trading Model," dated December 11, 2014, available at eis.bcaresearch.com The post-June 9, 2016 fractal trading model rules are: When the fractal dimension approaches the lower limit after an investment has been in an established trend it is a potential trigger for a liquidity-triggered trend reversal. Therefore, open a countertrend position. The profit target is a one-third reversal of the preceding 13-week move. Apply a symmetrical stop-loss. Close the position at the profit target or stop-loss. Otherwise close the position after 13 weeks. Use the position size multiple to control risk. The position size will be smaller for more risky positions. 1 Your author is a former pilot in the Royal Air Force reserve. 2 For an Airbus A330. 3 Tragically, a combination of flight data misinterpretation and pilot error at 35,000 feet was disastrous for Air France flight AF447 flying from Rio de Janeiro to Paris in June 2009.
