Navy Times editor\u2019s note: <\/b> U.S. stocks plummeted today<\/a> despite the Federal Reserve\u2019s shock move to slash interest rates to near zero. Or perhaps it was because of the Fed\u2019s move, which was designed to shore up a shaky economic as the global coronavirus pandemic marches on. It was the second emergency interest rate cut in as many weeks. Markets halted trading multiple time today after prices tumbled below benchmark levels. Luckily, we\u2019re part of a service<\/a> that provides smart experts to figure out what\u2019s going on and what officials might do to fix it. Take it away Dr. Jonathan T. Fluharty-Jaidee.<\/p>\n\n\n\n

1. What measures prevent a free fall in prices?<\/b><\/i><\/p>\n\n\n\n

Most financial markets<\/a> around the world have so-called circuit breakers that are triggered when overall prices drop by a certain magnitude.<\/p>\n\n\n\n

For example, if the price of the Standard & Poor\u2019s 500 index falls 7 percent <\/a>from its previous close, trading of all stocks on the two major U.S. stock exchanges \u2013 the New York Stock Exchange and the NASDAQ \u2013 is suspended for 15 minutes. If it drops an additional 6 percent, trading halts for another 15 minutes. If the S&P 500 drops a further 7 percent \u2013 for a total drop of 20 percent \u2013 then trading ceases for the day.<\/p>\n\n\n\n

A 7 percent drop has happened several times<\/a> in the current crisis, most recently just three minutes into trading on March 16<\/a> following the Federal Reserve\u2019s surprise decision to cut interest rates<\/a> to near-zero.<\/p>\n\n\n\n

Additionally, there\u2019s something known as the \u201climit up, limit down\u201d rule<\/a>, which set limits on how much any stock, exchange-traded fund or futures contract can go up or down in a five-minute period before triggering a temporary halt in trading for that security.<\/p>\n\n\n\n

This rule was created in reaction to the so-called flash crash in May 2010<\/a> in which a single algorithmic trade led to a 1,000-point intraday drop in the Dow Jones Industrial Average \u2013 at the time worth approximately $1 trillion in market value.<\/p>\n\n\n\n

2. Have these measures been triggered before?<\/b><\/i><\/p>\n\n\n\n

U.S. markets first began implementing circuit breakers in 1988 following the \u201cBlack Monday\u201d crash on Oct. 19, 1987, when the S&P 500 fell 22.6 percent<\/a>. The goal was to reduce overall market volatility<\/a>.<\/p>\n\n\n\n

The first and last time U.S. markets hit the circuit breaker \u2013 before this year \u2013 was during the Asian financial crisis<\/a> on Oct. 27, 1997. <\/p>\n\n\n\n

This shows just how infrequent price changes of this magnitude are. Neither the dot-com crash of 2000 nor the 2008 financial meltdown triggered a circuit breaker.<\/p>\n\n\n\n

3. Do they work?<\/b><\/i><\/p>\n\n\n\n

It depends on what we mean by \u201cwork.\u201d<\/p>\n\n\n\n

Their intended purpose<\/a> was to stop a deluge of traders selling assets at increasingly lower prices to get out before the market collapses entirely \u2013 and in effect contributing to that collapse.<\/p>\n\n\n\n

This type of fear-driven run on the markets is dangerous: If no one is taking the buy position, it becomes a race to the bottom<\/a>.<\/p>\n\n\n\n

Since circuit breaks are rare and we don\u2019t have lots of events to go on, it\u2019s hard to say how effective they are. But so far, every time they\u2019ve been triggered, stocks have rebounded the following day. That\u2019s what happened<\/a> in October 1997, and when the breakers were triggered on March 9<\/a> and March 12<\/a> of this year.<\/p>\n\n\n\n

This suggests they were effective at ending panic selling \u2013 at least temporarily. They are not intended to prevent markets from continuing to go down. And research shows circuit breakers may actually increase market volatility in the days and weeks that follow<\/a>. This means that while prices rebound the day following a trading halt, markets experience larger swings in prices over a longer period, which is generally seen as a bad thing.<\/p>\n\n\n\n

And just because the halts have led to rebounds in the past doesn\u2019t mean they\u2019ll keep doing so.<\/p>\n\n\n\n

4. So why not just shut down markets for a while?<\/b><\/i><\/p>\n\n\n\n

The president does have the power to shutter markets in response to a crisis such as the COVID-19 pandemic.<\/p>\n\n\n\n

In fact, the markets have been closed many times<\/a> due to war, victory, deaths of presidents, the celebration of historical events of significance like the Moon landing and disasters, both natural or man-made. <\/p>\n\n\n\n

For example, the NYSE shut down for three days following the 9\/11 terrorist attacks<\/a> and closed for two days during Hurricane Sandy in 2012.<\/a><\/p>\n\n\n\n

The longest shutdown on record<\/a> was during World War I, when the the NYSE closed for four months beginning in July 1914.<\/p>\n\n\n\n

Normally, however, the market remains open as much as possible even during periods of financial crisis, and the management of each exchange is responsible for determining whether there will be trading that day or not. The government, however, has broad powers in regulating commerce<\/a> during national emergencies, which includes the ability to order a shutdown.<\/p>\n\n\n\n

5. So should President Donald Trump order one?<\/b><\/i><\/p>\n\n\n\n

There\u2019s actually no research that I\u2019m aware of on the efficacy of closing down stock markets during crises. But it\u2019s important to understand that even when markets are crashing, investors usually prefer them to stay open so they can continue to trade.<\/p>\n\n\n\n

Moreover, the U.S. holds a principal place in the financial world as a strong and active market for trading securities. If the market is closed too long, or for capricious reasons, it can give the signal that American markets are not free of government intervention and that they are unreliable.<\/p>\n\n\n\n

While temporary halts to trading gives market participants time to parse information and make more levelheaded decisions, a shutdown could cause real damage to U.S. investments in the long run if they\u2019re seen as less of a haven to global investors.<\/p>\n\n\n\n
