What Is Taper Tantrum?

The term "Taper Tantrum" refers to the swift and dramatic reaction of financial markets to the prospect or actual process of curtailing quantitative easing (QE) policies by a central bank, particularly the U.S. Federal Reserve.

This typically includes sudden spikes in interest rates, market volatility, and abrupt outflows from emerging markets.

It was first coined during the summer of 2013. It occurred after then-Chairman of the Federal Reserve, Ben Bernanke, stated that the Fed might begin tapering or gradually reducing its QE program.

This involved large-scale purchases of government bonds to stimulate the economy in the aftermath of the 2008 financial crisis.

Background of Taper Tantrum

The term "Taper Tantrum" refers to the reaction of financial markets to the announcement made by the then-Federal Reserve Chair Ben Bernanke in May 2013.

  • Post-Financial Crisis Era (2008-2013): After the 2008 global financial crisis, the Federal Reserve (Fed) implemented unconventional policy measures to stabilize the economy.

This included quantitative easing, a policy in which the central bank buys government securities or other securities from the market to increase the money supply and encourage lending and investment.

  • Quantitative Easing: Between 2008 and 2013, the Federal Reserve carried out multiple rounds of QE, known as QE1, QE2, and QE3.

These actions helped to keep interest rates low to stimulate economic growth but also led to a lot of new money being introduced into the financial system.

  • May 2013 - The "Taper" Announcement: In May 2013, Bernanke suggested that the Fed might start to "taper" its asset purchases due to improvements in the economic outlook.

This surprised many investors who had become accustomed to the Fed's policy of QE.

  • Market Reaction - The "Tantrum": The suggestion that the Fed would reduce its level of support led to a sharp increase in U.S. Treasury yields as markets anticipated the end of easy money. This was the "tantrum."

The markets coined the term "Taper Tantrum" to describe this volatile reaction.

  • Global Impact: Emerging markets, many of which had benefited from the search for yield in the era of QE, were also severely affected. They experienced significant capital outflows and currency depreciation as investors returned money to the U.S.

  • Learning Experience: The Taper Tantrum taught the Fed and other central banks valuable lessons about communication and the impact of changing monetary policy after a long easing period.

This experience has influenced how such transitions are handled to minimize market disruptions.

Factors Driving the Taper Tantrum

Investor Expectations

Investor expectations played a crucial role in the Taper Tantrum.

The Fed's announcement about tapering its QE program surprised many investors who had grown accustomed to the low-interest-rate environment. The prospect of reduced liquidity and higher interest rates led to a sell-off in bond markets and a shift away from riskier assets.

Communication and Forward Guidance

The Taper Tantrum underscored the importance of communication and forward guidance in monetary policy. The sudden announcement about tapering QE, without clear guidance about the timing and pace, created uncertainty in financial markets.

This episode highlighted the need for central banks to communicate their policy intentions clearly and transparently to avoid sudden market reactions.

Market Liquidity

Market liquidity, or the ease with which assets can be bought or sold without affecting their price, was another factor behind the Taper Tantrum.

The prospect of the Fed reducing its bond purchases raised concerns about lower liquidity in the bond market, leading to higher yields and increased volatility.

Factors Driving the Taper Tantrum

Consequences of the Taper Tantrum

Impact on Bond Yields

One of the most significant effects of the Taper Tantrum was the sharp increase in bond yields, especially U.S. Treasury yields.

This rapid rise in yields reflected investors' expectations of higher interest rates and reduced liquidity in the bond market. The increase in yields also led to capital losses for bondholders, as bond prices fall when yields rise.

Effect on Emerging Markets

Emerging markets were particularly affected by the Taper Tantrum. The prospect of tighter monetary policy in the U.S. led to capital outflows from emerging markets, putting downward pressure on their currencies and upward pressure on their interest rates.

This posed challenges for these economies, increasing their borrowing costs and leading to higher inflation.

Implications for Monetary Policy

The Taper Tantrum had significant implications for monetary policy. It underscored the importance of clear and transparent communication in managing investor expectations.

It also highlighted the global spillover effects of monetary policy decisions by major central banks, underscoring the need for careful coordination and communication at the global level.

Managing a Taper Tantrum

Clear and Predictable Communication

One of the key lessons from the Taper Tantrum is the importance of clear and predictable communication in monetary policy. Central banks must provide clear guidance about their policy intentions to manage investor expectations and avoid sudden market reactions.

In the wake of the Taper Tantrum, the Fed has sought to improve its communication and provide more explicit guidance about its policy path.

Monetary Policy

Monetary policy plays a crucial role in managing a Taper Tantrum. Central banks can influence market conditions and investor expectations by setting interest rates and controlling the money supply.

In the event of a Taper Tantrum, central banks may need to adjust their policy stance to stabilize markets and mitigate the adverse effects on the economy.

Diversification as a Mitigation Strategy

Diversification is another strategy to manage a Taper Tantrum. By diversifying their portfolios across different asset classes and geographies, investors can mitigate the risks associated with changes in monetary policy.
