What Was Operation Twist?
Operation Twist refers to a Federal Reserve monetary policy initiative used in the past, which was designed to lower long-term interest rates to further stimulate the U.S. economy when traditional monetary tools were lacking via the timed purchase and sale of U.S. Treasuries of different maturities.
The term gets its name from the simultaneous buying of long-term bonds and selling short-term bonds, suggests a "twisting" of the yield curve and creating less curvature in the rates term structure.
- Operation Twist is a monetary policy tool used by central banks aimed at stimulating economic growth through lowering long-term interest rates.
- This is achieved by selling near-term Treasuries to buy longer-dated ones.
- Operation Twist effectively "twists" the ends of the yield curve where short-term yields go up and long-term interest rates drop simultaneously.
- Operation Twist was first attempted in 1961, and again in the years following the 2008-09 financial crisis.
Understanding Operation Twist
The name 'Operation Twist' was given by the mainstream media due to the visual effect that the monetary policy action was expected to have on the shape of the yield curve. If you visualize a linear upward sloping yield curve, this monetary action effectively "twists" the ends of the yield curve, hence, the name Operation Twist. To put it another way, the yield curve twists when short-term yields go up and long-term interest rates drop at the same time.
The original 'Operation Twist' came about in 1961 when the Federal Open Market Committee (FOMC) sought to strengthen the U.S. Dollar (USD) and stimulate inflows of cash into the economy. At this time, the country was still recovering from a recession following the end of the Korean War. In order to promote spending in the economy, the yield curve was flattened by selling short-term government debt in the markets and using the proceeds from the sale to purchase long-term government debt.
The operation describes a form of monetary policy where the Fed buys and sells short-term and long-term bonds depending on their objective. However, unlike quantitative easing, Operation Twist does not expand the Fed's balance sheet, making it a less aggressive form of easing.
In June 2012, Operation Twist was so effective that the yield on the 10-year Treasury dropped to a 200-year low.
Remember there is an inverse relationship between bond prices and yield—when prices go down in value, the yield increases, and vice versa. The Fed’s purchasing activity of long-term debt drives up the price of the securities and, in turn, decreases the yield. When long-term yields fall faster than short-term rates in the market, the yield curve flattens to reflect the smaller spread between the long-term and short-term rates.
Also note that selling short-term bonds would decrease the price and, hence, increase the rates. However, the short end of the yield curve based on short-term interest rates is determined by expectations of the Federal Reserve policy, rising when the Fed is expected to raise rates and falling when interest rates are expected to be cut.
Since Operation Twist involves the Fed leaving short-term rates unchanged, only the long-term rates will be impacted by the buy and sell activity conducted in the markets. This would cause long-term yields to decrease at a higher rate than short-term yields.
Operation Twist Mechanism
In 2011, the Fed could not reduce short-term rates any further since the rates were already at zero. The alternative then was to lower long-term interest rates. To achieve this, the Fed sold short-term Treasury securities and bought long-term Treasuries, which pressured the long-term bond yields downward, thereby, boosting the economy.
As short-term Treasury bills and notes matured, the Fed would use the proceeds to buy longer-term Treasury notes and bonds. The effect on short-term interest rates was minimal as the Fed had committed to keeping short-term interest rates near zero for the next couple of years.
A fall in interest rates reduces the cost of borrowing for businesses and individuals. When these entities have access to loans at low interest rates, spending in the economy increases and unemployment falls as businesses can affordably secure capital to expand and finance their projects.
