Operation Twist: Steering the Yield Curve
Operation Twist, officially known as the Maturity Extension Program, is an unconventional monetary policy tool employed by central banks, most notably the U.S. Federal Reserve (the Fed), to influence long-term interest rates and stimulate economic activity. It gets its quirky name from a popular dance craze of the 1960s, implying a twisting or reshaping of the yield curve.
The core mechanism of Operation Twist involves the simultaneous purchase of long-term government bonds and the sale of short-term government bonds. This is crucial: the central bank isn’t simply injecting more money into the economy. It’s altering the composition of its existing holdings of government debt.
The logic behind this maneuver is multifaceted. Purchasing long-term bonds increases their demand, driving up their prices and consequently lowering their yields (interest rates). Conversely, selling short-term bonds increases their supply, lowering their prices and increasing their short-term yields. This action “twists” the yield curve, flattening it by compressing the difference between long-term and short-term interest rates.
Why would a central bank want to flatten the yield curve? The primary motivation is to lower long-term borrowing costs. These rates are particularly influential for major economic decisions like mortgage rates, corporate investment in long-term projects, and consumer spending on durable goods. By making it cheaper to borrow money for these purposes, the central bank aims to encourage economic growth and investment.
A flatter yield curve can also signal the central bank’s commitment to keeping interest rates low for an extended period. This communication channel can further boost confidence among businesses and consumers, encouraging them to take on debt and invest in the future.
The Fed implemented Operation Twist twice. The first time was in 1961, aiming to weaken the dollar and improve the U.S. trade balance. The more recent iteration occurred between September 2011 and December 2012, in the aftermath of the 2008 financial crisis. At that time, the Fed purchased $400 billion of Treasury securities with maturities of 6 to 30 years and simultaneously sold an equivalent amount of Treasury securities with maturities of 3 years or less.
The effectiveness of Operation Twist is a subject of ongoing debate. Some argue that it had a limited impact on long-term rates and economic growth. Critics point out that interest rates were already very low at the time of the 2011-2012 program, limiting the potential for further reduction. They also suggest that other factors, such as global economic conditions and investor sentiment, play a more significant role in determining long-term rates.
However, proponents argue that Operation Twist did contribute to easing financial conditions and supporting the economic recovery, albeit modestly. They contend that it provided a valuable signal of the Fed’s commitment to low interest rates and helped to reduce uncertainty in the market. Despite the differing opinions, Operation Twist remains a notable example of a central bank’s attempt to fine-tune the yield curve and stimulate economic activity through unconventional monetary policy.
