The Global Savings Glut by LPL Financial
Can savings be a bad thing? Many people think of saving money as a best practice when it comes to managing their finances, but if everyone in an economy (or even just a single saver that controls much of the wealth) saves at the same time, spending is likely to decline, leading to slower near-term economic growth. This concept also applies to countries. When countries save more than they “spend” (e.g., invest), they may actually cause problems related to slower growth, including downward pressure on interest rates, deflation, and weaker stock market performance. Economists who believe we’re in the middle of a “global savings glut” think that’s exactly what’s happened in recent years. Figure 1 shows some of the potential implications of a global savings glut, which will be discussed in more detail later.
What is a Savings Glut?
The global savings glut hypothesis, which was popularized by Former Federal Reserve Chair Ben Bernanke more than 10 years ago, states (in basic terms) that the world is dealing with an excess of savings, and, as a consequence, insufficient investment. The theory is controversial and competing theories exist, but it does help to explain some of the issues faced by the world economy in recent years.
The negative impact of saving too much makes more sense when considered from an economic perspective. Spending, whether from consumers, businesses, or governments, ultimately drives economic growth. The major benefit of saving from an economic perspective is that it allows us to push spending forward, whether we’re “saving up” for something or planning for a time when our income levels might decline, such as retirement. Thus, although we may need to build up our savings initially, the ideal outcome for continued growth is for those savings to lead to increased spending in the future.
One way a country’s “savings” can be measured is through its current account balance, which economists think of as the amount a country saves minus what it invests domestically. This difference is reflected in trade relationships, which is another way of looking at the significance of the current account balance. A country with a trade surplus is exporting more than it imports, or saving more than it invests back into its country. Just as a consumer spending less and saving more will result in slower economic growth today, the same is true for any individual country.
How a country disposes of its savings also matters. Over time, the total of all of the individual current account surpluses and deficits in the world should net out to zero, meaning if one country “borrows” through a current account deficit, another country will “lend” from its surplus. But over the short term, the numbers don’t always net out; because just like a consumer can have a savings account, a country can place its savings in reserve. In fact, this is what has happened in recent years, leading to a net current account surplus for the world [Figure 2].
Drivers Of The Global Savings Glut
The primary drivers of the global savings glut originate in both emerging market (EM) and developed countries, with several contributing factors, such as a need to reduce debt, low demand for investment, aging populations, and the large amount of cash held by corporations.
EM Countries: Historically Big Savers
EM countries, led by China, were historically big savers and ran large current account surpluses over time. In response to the late 1990s Asian financial crisis, EM countries set out to reduce debt and increase savings. EM countries also tend to have higher savings rates than developed nations, given weaker social safety nets. Additionally, the commodities boom of the 2000s boosted revenue for many EM countries, especially heavy commodity exporters in the Middle East.
For years, China has been perhaps the most significant driver of global savings. Current account surpluses increased given its historically heavy reliance on exports, but its reserves, at more than $3 trillion, are still the largest in the world. China’s foreign reserves have been falling recently, though, due to a slowing economy, investment in a transition to a more consumer-oriented economy, and most recently, using reserves to weaken its currency.
Eurozone: The New Source of Surplus
China’s slowdown has been offset by Germany, which has quietly become the new current account surplus champion of the world, first taking the crown in 2011. This surplus is in large part being caused by the “one-size-fits-all” approach of the euro. If Germany, which has one of the stronger economies in the Eurozone, had an independent currency, it would likely be stronger than the euro is now, which would make German exports more expensive. But given that the European Central Bank’s (ECB) easy money policy?—?mainly intended to help slower-growing peripheral nations?—?also applies to Germany, the weakened euro is helping boost demand for German exports, leading to a large current account surplus. Many countries in the Eurozone periphery have also seen increased surpluses; however, in contrast to Germany and EM countries, the surpluses are largely due to economic weakness, where demand for investment remains low. Figure 3 shows how the sources of global surpluses have changed over time.
The Role of Aging Populations and Corporate Cash
Aging populations in developed countries are one of the main drivers of the savings glut. An increasing proportion of employees are in the later years of their working lives, and on average, savings rates are highest in preparation for retirement. This behavior may help explain why Japan has experienced years of current account surpluses, even though it has been mired in a slow growth environment for years. The amount of cash held by corporations may also be having an impact, with much of the cash held overseas to avoid repatriation taxes.
Although surpluses are the main subject here, no discussion of surplus and deficit could be complete without addressing why the U.S., the largest economy in the world, has (and continues to run) a current account deficit. The major reason is that investment in the U.S. has continued to outpace savings due to an attractive business environment, liquid and developed financial markets that attract foreign capital, and the dollar’s position as the world’s preeminent reserve currency.
What Are The Impacts Of A Savings Glut?
Slower Economic Growth
In the short term, a current account surplus can be viewed as deferred economic growth, as savings do not contribute to consumption or investment today. Additionally, investments in new equipment, processes, and technology tend to increase economic growth over time, so a lack of current investment means future growth is also likely to be impacted. Slower economic growth in response to too much savings has several potential implications.
Lower Interest Rates
One of the largest impacts of the global savings glut is falling, or low, interest rates. Countries generally don’t seek to make money on their foreign reserves, and therefore, they invest in perceived safe-haven securities that can help preserve their buying power, such as Treasuries and high-quality sovereign debt of other developed nations,
