The article examines whether foreign dollar inflows before the 2008 crisis reflected “inordinate savers” increasing holdings in U.S. assets or “thriving traders” acquiring dollars through trade deficits. It links each behavior to distinct movements in exchange rates and balance-of-payments data, then evaluates evidence around the U.S. housing bubble. It also lays out current-account basics, showing how deficits correspond to net financial inflows and how cross-border savings decisions drive those identities.

The Foreign Savings Glut: Inordinate Savers or Thriving Traders?

Current-Account Basics

# The Foreign Savings Glut:Inordinate Savers or Thriving Traders? Owen F.Humpage In the years prior to our recent economic crisis,foreign savings poured into the United States.Did foreign traders whohappened to acquire dollars from American trade defcits merely choose to keep these funds in dollar-denominatedassets?Or,did foreigners decide to increase their savings inordinately and place those funds in dollar-denominated as-sets?The answer is key to the debate about the sources of liquidity that paved the way to our recent economic problems. A lively debate has arisen over the contribution that foreignsavings may have made to our current economic problems.Some economists argue that a glut of foreign savings fowedinto the United States and helped to inflate the U.S.hous-ing bubble,whose bursting caused the financial turmoil thatled to our recent recession.To be sure,in the decade beforethe U.S.housing bust in 2006,foreign savings poured intothe United States.The savings-glut hypothesis,however,im-plies that the foreigners providing the influx of funds were"inordinate savers,"who placed their wealth in U.S.assets,as opposed to "thriving traders,"who acquired and held onto a substantial quantity of dollar-denominated assets.Thedistinction is subtle,but key to the debate. Each of these behaviors leaves a distinct footprint on ourexchange rates and balance of payments,so these datamight help to tell the tale.When inordinate foreign savingsis driving events,a dollar appreciation will accompany anexpanding current-account deficit.When thriving foreigntraders hold sway,a dollar depreciation will go hand-in-handwith a growing current-account deficit. Both patterns have appeared in our accounts over theyears,but the data leading up to the bursting of the hous-ing bubble does not seem consistent with the savings-gluthypothesis.From early 2002 through late 2005,the dol-lar depreciated broadly as the U.S.current-account deficitgrew,suggesting that thriving foreign traders,not inordinateforeign savers,determined events. Number 2010-3 May 24,2010 ## Current-Account Basics A one-to-one correspondence exists between a nation'scurrent-account balance and the financial flows that cross itsborders.In 2008,when the United States ran a $706 billioncurrent-account deficit,it also experienced a $706 billion netinflow of foreign funds,ignoring measurement error.Thatsame year,China maintained a $426 billion current-accountsurplus and experienced a net financial outlow of equivalentsize.This fundamental correspondence comes about wheth-er driven by domestic-consumption choices-and trade-orby foreign-savings decisions. The United States has run a current-account deficit almostcontinuously since 1982.When our imports exceed our ex-ports,we pay for the surfeit of imports by offering the rest ofthe world financial claims against our future output.Thesefinancial claims consist of such things as stocks,bonds,Trea-sury securities,and bank accounts.Private individuals andbusinesses across the globe hold most of these claims,butforeign governments,their central banks,and internationalorganizations take up a good portion.The issuance of thesefinancial claims creates a net flow of foreign savings intothe United States,which,in the absence of measurementerror,must exactly equal our current-account deficit.Shouldthe flow of foreign savings ever start to diverge from theaccumulating current-account deficit,exchange rates-andpossibly other economic variables-will adjust to maintainthe accounting identity between the two. In contrast to the United States,China has run a current-account surplus almost consistently since 1990.Prior to2004,that surplus was fairly small,but since then it has ex-panded sharply.When Chinese traders export more goodsand services than they import,they receive foreign currencyin payment for the balance.China then invests these earn-ings in foreign-currency-denominated assets,thereby chan-neling the funds back into the financ

FAQs

What debate does the article focus on regarding foreign savings?

It asks whether foreign traders channel dollar inflows by simply holding acquired dollars, or whether foreigners increased savings in a way that placed funds into dollar-denominated assets, fueling liquidity and crisis dynamics.

How does the article connect inordinate savers vs thriving traders to exchange rates?

It states that inordinate foreign savings driving events should coincide with dollar appreciation as current-account deficits expand, while thriving traders should coincide with dollar depreciation alongside a growing current-account deficit.

What is the “one-to-one” relationship described for current accounts?

The article explains that a nation’s current-account balance corresponds directly to net financial flows across its borders: for example, a U.S. deficit is paired with an equal net inflow of foreign funds, up to measurement error.
