The very concept of
negative interest rates seems counterintuitive. After all, why would you
pay someone to hold your money for you? It intrinsically seems wrong
(even though we're already doing it by paying banks monthly fees for various
services).
The new reality of
negative interest rates came home to roost when Switzerland's central bank moved to unpeg the
Swiss franc from the euro. While that move roiled the markets, the SNB's
announcement that it was dropping interest rates further into negative
territory on deposits to minus 0.75 percent. On top of that, effective
January 20th, Denmark's central bank announced that it was
joining the negative interest rate crowd by lowering the rate on certificates
of deposit to minus 0.20 percent. The central banks of both of these
countries made the move further into negative interest territory in a move to
prevent their currencies from appreciating any further against the euro.
In both cases, intervention in the currency market through the purchasing
of euros with both Danish kroner and Swiss francs had failed to stem the flow
of euros into both nations. Why would both Denmark and Switzerland be so
concerned about the strength of their currencies, particularly against the
euro? In both nations, their major trading partner is Europe. When
their exports to Europe become too expensive because of the high value of both
the kroner and the franc, their economies will suffer. On top of that, it
will be cheaper for Danes and Swiss consumers to import/buy goods from Europe
since the euro is relatively cheap, again, negatively impacting the local economy.
Now, let's look a bit
more deeply at the entire concept of negative interest rates. An
interesting paper on negative interest rates was published by the Federal
Reserve Bank of New York back in August 2012. The paper entitled "If Interest Rates Go Negative....Or, Be Careful What You
Wish For" by Kenneth Gorbade and Jamie McAndrews provides us
with an interesting examination of what happens when interest rates go
sub-zero. Here is a summary.
To set the stage, we
first have to look at banking system reserves and excess reserves that are held
by the Federal Reserve. Right now, the Federal Reserve actually pays the
banking system 0.25 percent interest to keep excess reserves
on deposit with the Fed. This experimental monetary policy came to life
in 2008 as part of the Emergency Economic Stabilization Act of 2008,
the Act that famously bailed out the entire U.S. financial system. The
logic behind this decision is quoted here:
"The payment of interest on excess reserves will permit
the Federal Reserve to expand its balance sheet as necessary to provide the
liquidity necessary to support financial stability while implementing the
monetary policy that is appropriate in light of the System’s macroeconomic
objectives of maximum employment and price stability."
The Fed
also believes that it can change the interest rate on excess reserves, an
action that will provide it with an important "exit strategy tool"
when it begins to remove monetary stimulus."
In the year prior to the
Great Contraction (i.e. 2007), required banking system reserves averaged $43
billion while excess reserves averaged a measly $1.9 billion. This
relationship had been pretty consistent over the previous fifty years, however,
in general, excess reserves were less than 10 percent of total reserve holdings
because depository institutions had an incentive to minimize excess reserves
since they earned no interest. As I noted above, all of that changed in
September 2008 when the Fed began to pay interest on excess reserves.
These actions by the Fed caused this to happen:
So, why did the banking
system send trillions of dollars to be stored in the Fed's vaults, figuratively
speaking, of course. Because, there is NO risk to having the Fed hold your
money and, as an added bonus, the banking system makes 25 basis points in
income for its trouble along with avoiding lending the money to those pesky consumers who might default on their loans!
Let's go back to negative
interest rates and the paper in question. The authors of the paper
suggest that, if economic conditions required, the Fed could push interest
rates in the broader economy into negative territory by charging interest on
excess bank reserves. By taking this step, which is similar to that taken
by Switzerland and Denmark, other interest rates would follow in lockstep.
Now, let's look at the
impact of negative impact on the economy. The authors suggest
that negative interest rates greater than 0.50 percent would have a significant
impact on the financial system. For instance, while small retail
investors may prefer to hold at least some cash rather than deposit money in a
bank account to avoid a negative interest rate charge, wealthy individuals,
corporations and governments would find this to be logistically impossible
since storing millions or billions of dollars worth of currency would be both
costly and provide a significant security risk.
Here are some of the
authors' projections about might occur in a negative interest rate environment:
1.) As the number of
individuals who wish to hold physical cash grows, the United States Treasury
Department will be forced to print more currency.
2.) In the case of larger
amounts, financial innovations would likely occur with the formation of special
purpose bank accounts that offer conventional checking services for a fee by pledge
to hold no assets but cash.
3.) Interest avoidance
strategies would emerge. For instance, a taxpayer could make large excess
payments on their individual income tax and property tax filings. In the
case of federal taxes, taxpayers would allow the IRS to hold their money and
refund the excess the following April. As well, holders of credit cards
could make a large advance payment and then run down the balance with
subsequent purchases.
4.) As interest rates
become more negative, consumers and businesses will have increasing incentive
to make payments quickly and receive payments slowly, changes that would also likely spawn financial innovation. This is in sharp
contrast to the reality that most of us have grown up with, particularly in the
late-1970s when spiralling short-term interest rates created a situation where
consumers and businesses wanted to delay making payments for as long as
possible and collect payments as quickly as possible.
The existence of negative interest rates will also impact the accounting profession. It is interesting to
observe that the International Financial Reporting Standards Foundation
(IFRS), a non-profit account organization that develops and promotes financial
reporting standards, has already recognized that negative interest rates are
having a significant impact in the "...presentation of income and
expenses in the statement of comprehensive income.". Interest
resulting from a negative effective interest rate on a financial asset does not
meet the definition of interest revenue because it reflects an outflow rather
than an inflow of economic benefits. It is also not an interest expense because it arises on a financial asset rather than a financial liability.
Obviously, the change to a negative interest rate environment will make a lot of
accountants and tax lawyers very, very wealthy as their clients scramble to
understand their new reality.
While the U.S. economy is
showing some signs of strength, it is also definitely not as healthy as it
could be, particularly when we look at long-term unemployed, declining
workforce participation rate, growing debt levels and overly elevated real estate
valuations in some markets (particularly parts of California) among others.
With interest rates at the zero bound, the Fed is running short of
ammunition to stimulate the economy if should happen to slow down again, a scenario
that is not all that unlikely given the slowing in both Europe and the Far East. As well, if the United States dollar continues to appreciate as investors flee to the
"currency of last resort" in growing numbers, the Fed may be forced to act to push the value of the dollar down as is the case in Denmark and Switzerland.
As it looks now, the Fed faces the
option of further bloating its already morbidly obese balance sheet or pushing
interest rates into negative territory if it is backed into a policy corner.
Unfortunately, as was true in the case of both quantitative easing and
interest rate twisting, the real impact of the negative interest rate
experiment is unquantifiable, however, there is one thing that
we can say for certain about negative interest rates; never, but never say
never.
