In this five-part series, financial journalist Frances Coppola, regularly featured in the Financial Times, The Economist, Forbes and a range of other financial industry publications, explores the global macro forces acting to change the values of economists’ classic measures. She discusses the tools the Federal Reserve used before the Great Recession of 2008 to help it decide what is the "right" level for interest rates, and explains how (and why) these tools appear to be failing today—and what it all means for businesses attempting to manage FX risk.
The so-called “neutral rates” of inflation, unemployment and interest rates collectively determine the point at which the economy is running at full capacity and inflation is stable. When inflation is stable, the currency exchange rate also tends be stable, which is good news for businesses managing FX risk. But the neutral rates themselves are changing in unpredictable ways as the global economy evolves.
The Fed uses the “neutral” rate of interest as a benchmark for its interest rate policy, which affects the dollar exchange rate. But the neutral rate seems to have fallen since the 1980s. Economists have many potential reasons for this, ranging from so-called “secular stagnation” to ageing populations saving more. But some say that the neutral interest rate itself is determined by Fed policy, while others doubt that the neutral interest rate even has an independent existence—all of which adds to dollar exchange rate uncertainty and FX risk management challenges.
Since the 1960s, economists have believed that there is a trade-off between unemployment and inflation: typically, when unemployment is low, inflation is high, and vice versa. But now, unemployment is at historic lows, yet inflation has not taken off. Could this mean the relationship between unemployment and inflation has broken down, and what does this mean for interest rates, the dollar exchange rate, and companies managing their FX risk?
Inflation is commonly believed to result when there is too much money chasing too few goods. High inflation tends to cause exchange rates to fall. But between 2008-14 the Fed put $4.6 trillion of new money into the economy, yet both inflation and the dollar exchange rate stayed on the floor. Why didn’t all this new money cause inflation—and what could happen to exchange rates now it is being withdrawn?
If the unpredictable evolution of what rates of inflation, unemployment and interest rates will enable an economy to run at “full capacity” isn’t confounding enough, the very notion of what constitutes full capacity may be subject to question. Many economists believe that the lower rates of global economic growth seen since the Great Recession may constitute a new, lower, normal for sustainable growth. And that could have ripple effects spreading into companies’ FX risk management thinking.
