Korean Monetary Velocity down – Korean Media Overreacts
MK English News (by 매일 경제) reports that the “Nation’s velocity of money showed its worst performance in the first quarter of 2009,” and that “In short, the real economy failed to benefit from a massive injection of capital by the government and monetary authorities to save the faltering economy.
‘In short’ – to put it bluntly – such a conclusion is itself short-sided. While the real economy might not have benefitted from the government’s massive capital injection (and only time will tell whether this is or is not the case) measuring the efficacy of the strategy half way through the execution by the monetary velocity is akin to measuring the health of a stroke patient by how fast he can run a kilometer. Sure monetary velocity is connected with the overall health of the economy, but not in such a causal way as to form the basis of a terminal prognosis. I’m just glad that Ms. Hong’s not my doctor. “I’m sorry madam, but your husband didn’t complete the test in the allotted time, I’m afraid there’s no hope. Never mind that his faculties have all returned to normal, a 15 minute kilometer means that he’s basically dead.”
Here is the article in full with a few comments.
The nation’s velocity of money showed its worst performance in the first quarter of 2009.
In short, the real economy failed to benefit from a massive injection of capital by the government and monetary authorities to save the faltering economy.
According to the Bank of Korea (BOK) on June 7, Korea’s velocity of money plunged to 0.687 in the first quarter of 2009, marking the first 0.6 range since record- keeping began.
Velocity of money is calculated by dividing Gross Domestic Product (GDP) with M2 which illustrates the speed of money circulation in the market.
This she’s got right, although it might be helpful to define M2: money and close substitutes for money – i.e. cash, cash equivalents, savings deposits, time deposits (CDs) of less than $100,000 value.
In terms of quarter, velocity of money has consistently maintained a 0.8 range since 2000. However, the figure declined from 0.807 at the 2007-end to 0.778 in Q1 of 2008, followed by 0.748 in Q2; 0.703 in Q3; and 0.6 in Q1 of 2009.
Another indicator, money multiplier–M2 divided by reserve money– sharply declined from 26.5 in October to 26.3 in November, 24.2 in December of 2008 and 22.5 in January 2009. The figure managed to edge up to 23.1 in February, but slid back to 22.4 in March 2009.
Here it would be prudent to explain what the money multiplier really is. The money multiplier is a measure of the total amount leverage from an initial money deposit at a given reserve requirement (the amount of money that can be loaned (or created)based on a certain deposit amount). And yes, the money multiplier is calculated as M2 divided by the reserve amount. If this indicator is dropping, either the reserve level has been elevated, or M2 has declined. But wait…
Velocity of money has been slowing down primarily due to a surge in money supply amid negative growth of the real economy.
Another reason behind the declining velocity of money is reluctance in the banking sector to lend. Banks have increased lending to small-and mid-sized companies as advised by governmental policy, but aggregate loan severely lags behind the previous year. Bank’s lending to corporate sector rose by 3.2 trillion won ($2.5 billion) compared with April of last year which is a third of last year’s 10.9 trillion won ($8.6 billion).

So basically here, Hong has explained how the money multiplier indicator has gone down. M2 has increased, but reserve levels at banks are uncommonly high. In effect, the government has released money to the banks, but they aren’t lending it out again.
In order to explain why Ms. Hong is using the wrong measure to judge the efficacy of the Korean government’s stimulus package, let’s look at what a capital injection is actually supposed to do. First, some basic economic monetary theory (don’t worry, I’m no economist, so I will keep this really basic).
GDP is defined as:
GDP = consumption + gross investment + government spending + (exports − imports)
In a recession situation where consumption, investment, exports and imports are all down, government uses two primary methods to bolster GDP
1. Increase G (government spending). If the government spends on things like tax cuts, development projects, and handouts, the funds spent by the government are theoretically multiplied as they change hands, increasing consumption and possibly even investment (e.g. tax cuts produce increased consumer spending, development projects increases funds going to workers who participate in the economy)
2. Cut the primary interest rate. In order to stimulate lending, the monetary authorities (the Fed in the US and Bank of Korea in Korea) will cut the rate at which they lend money to banks. Savings are then theoretically passed on to credit consumers – both individuals and corporations, who increase spending – in turn increasing consumption, investment, and possibly exports.
Now the question of velocity:
The relationship of velocity to GDP is defined in the following relationship:
![]()
Where nQ is nominal GDP (GDP adjusted for inflation), M is the supply of money in terms of M2, and V is monetary velocity.
Both government spending and interest rate cuts are designed to increase overall GDP. However, both also have the tendency to increase the overall money supply (M).
Hong is quite right in her assessment that the velocity “has been slowing down primarily due to a surge in money supply amid negative growth of the real economy.” However, her conclusion that “the real economy failed to benefit from a massive injection of capital by the government and monetary authorities” based on depressed monetary velocity fails to recognize what the primary purpose of government stimulus is.
Velocity has been shown to peak and decline just before or during a recession, and velocity decline generally outlasts the real-economy recession. Below is a historical chart of US monetary velocity which I borrow from a fantastic article on monetary velocity by Goldseek.com that illustrates this point well.

The real question is: “to what extent will the stimulus buoy GDP.” For that I’m afraid the jury is still out.
What does this velocity talk mean for businesses? Not much really. I’d think the Korean consumer confidence index, which is at a 2-year high, or manufacturer sentiment, which is at a 7-month high would be a more useful indicators of the near future. While Korea is definitely not out of the woods, and the real economy may not have bottomed out just yet, most economists are cautiously optimistic. As for monetary velocity, banks will loosen their hold on funds, individuals and companies will increase their appetites for credit, and M2 is likely to increase dramatically over the short term. As GDP recovery will follow more slowly, monetary velocity is likely to remain low for some time. Frankly speaking, I don’t give a flying fuck, and neither should you.
