Can A Nation $19 Trillion In Debt Afford Higher Interest Rates & Will This Change Our Retirements?
by Daniel R. Amerman, CFATweet
For some years now, very low interest rates have been reducing the earnings of retirement investors as well as the lifestyles of many of those already retired. To understand why this has been happening – and why it may continue for a very long time – one must recognize that there is a direct relationship between the interest rates that are paid to savers, and the interest payments made by a heavily indebted federal government.
For a retirement investor who is currently earning a 1% interest rate, a 5% increase in rates to a 6% return would increase their total investment earnings by 1,263% over 30 years, allowing for a radical improvement to their eventual retirement standard of living.
And for a current retiree who is drawing down their investment portfolio over 20 years, a 5% increase in annual interest rates from 1% to 6% would allow them to raise their standard of living by a full 57% in each and every one of those years.
Because the government borrows the money to make interest payments, this could set off a chain reaction of paying interest on money borrowed to pay interest, leading to a national debt increase of the current $19 trillion up to $94 trillion in 20 years. So unless there are some huge tax increases, a 5% increase in interest rates would increase the national debt by $75 trillion.
To put such a fantastic number in more personal terms, if we divide it by the number of American households with incomes above the poverty line, that means that for each able to pay family, their personal share of the national debt would rise by almost $700,000.
So the very same major increase in interest rates that so many millions of savers badly need for their financial security – could simultaneously send the national debt spiraling upwards and out of control.
Let me suggest that this relationship creates an extraordinary financial conflict of interest between savers and the government.
Many people believe that the enormous national debt is a somewhat theoretical problem for the future. That is, they suspect that it will at some point be a great financial burden for our collective children and grandchildren to deal with, but they don't see a direct impact on people's lives today in any major or practical way. At the same time, they are quite frustrated by the very low interest earnings that could force them to delay retirement, or if they are currently retired, that are already reducing their standard of living.
What they fail to see is that record setting national debts and record low interest earnings for savers are not separate issues but rather they're two sides of the same coin.
When we understand this essential point, we can see that massive national debts dramatically and directly impacting the lives of many millions of people is not something to anticipate in the distant future, but rather it is happening right now just as it did last year, and just as it will likely happen again next year.
And in seeking viable solutions for investing in this challenging environment, there is no substitute for understanding why it is that we currently have such low interest rates, and why they may continue into the indefinite future.
A Mysterious Reduction In Interest Payments
The graph below shows the amount of federal debt outstanding over the last 40 years. As can easily be seen, the federal debt exploded upwards with the financial crisis of 2008, and began its meteoric ascent to the over $19 trillion dollars outstanding.
Given its sheer size, if the interest rate on that debt were to rise by even 1%, the annual federal deficit rises by $190 billion. A 2% increase in interest rate levels would up the federal deficit by $380 billion, and if rates were 5% higher, the annual federal deficit rises by $950 billion.
Now ordinarily if we think about having our debts balloon out of control, we would expect to be making much higher interest payments.
That is, all else being equal, if our debt doubles or triples then our interest payments should double or triple.
As can be seen in the following graph, however, this hasn't been the case for the US government.
To the contrary, interest payments by the federal government have either been falling or level ever since the financial crisis began.
How can this be?
As plainly shown in the graph, the answer is that interest rates have in recent years plunged to their lowest levels in the last 40 years. It should also be noted that the highly publicized 0.25% increase in the Fed Funds rate range by the Federal Reserve in December of 2015 was very small – interest rates are still far, far below normal.
At the very same time, savers and investors have also been experiencing these very low interest rates.
Government Interest Rate Interventions
Now if someone viewed the federal government's being in debt as being similar to an individual being in debt, they might wonder if this just comes down to extraordinarily good luck. To have interest rates plunging even as the amount of debt outstanding was soaring upwards!
And generally speaking, this is where a lot of confusion can occur when trying to understand the debt and the deficit, because indebted national governments that can borrow in their own currencies are nothing whatsoever like individuals or corporations being in debt.
In the case of the United States, interest rates have been controlled for some years now through the actions of the Federal Reserve.
That is, as illustrated in the graph below, at the very same time that the federal deficit has been soaring, the Federal Reserve has been quite literally creating trillions of dollars out of the nothingness and using this brand new money to purchase United States debt – not directly from the US government, but through the markets.
In doing so, the Fed has taken control of interest rates in the short, medium and long term in the United States. (It is worth noting that that this process of quantitative easing has not actually ended in the US, it has just stabilized, with the Fed buying enough securities to replace principal payment receipts, thereby keeping total holdings level.)
Thus there is nothing fortuitous or "lucky" about the current very low interest rates – but rather they are a direct result of governmental policies.
The Impact On Savers & Investors
How do interest rates impact someone who is pursuing a long term investment program, perhaps to fund a desired retirement lifestyle?
As shown in the above graph, a saver who invests at a 7% rate for 30 years can expect to turn a $10,000 initial investment into a $76,123 investment, meaning their total earnings were $66,123. This is the math that drives conventional long-term investment models – each dollar invested creates another six dollars and more, thus savers who practice long-term discipline are highly rewarded over time.
And if the saver were able to get a 10% rate of return, then their earnings would soar to $164,494, with that 3% increase in interest rates leading to a near tripling of investment returns.
On the other hand, if we drop that interest rate to 1% – then the profits earned over thirty years plummet from $66,123 to $3,478, which is a reduction of 95%.
If interest rates turn out to be 2% on average, a saver would fare better with earnings of $8,114, but that is still a reduction of 88%.
The Federal Government's Interest Rate Problem
While little remarked upon or understood, the United States government has an interest rate-related problem of its own when it comes to the debt and the deficit.
That is, tax revenues are not sufficient for the federal government to make either principal or interest payments on the federal debt.
So each time a principal payment is due – the federal government issues a new debt to get the money to pay off the old debt.
And each time an interest payment is due, the federal government issues new debt to make that interest payment. Indeed, borrowing the money to make interest payments is the source of over half of the annual federal deficit.
What this means is that the federal government has a compound interest problem, as shown in the graph below. The issue is not just about the interest rate itself going up, but the amount of borrowing that must be entered into to pay those interest payments rises sharply as well.
Thus the exact same rising interest rates that would provide what savers need – which is the rapid compounding of investment interest – would simultaneously set off the extraordinary danger of a rapid compounding of debt interest for the federal government.
As shown in the graph, and explored in further detail here, a 5% increase in interest payments for the federal government would cause the level of federal debt to rise to $94 trillion over the next 20 years because of the compounding of interest, and a 10% increase in interest rates would cause the federal debt to climb to well over $200 trillion.
Shared Interest Rates, Opposite Objectives
Now if interest rates were entirely different for savers and investors than they were for the federal government, this problem with the government needing low interest rates on its extraordinary amount of debt would not be an issue for savers and investors.
Unfortunately, as we can see, the opposite is true.
Whether explicitly stated or not, almost all interest rates are effectively tied to what is known as the risk free rate, which is the government bond rate. In other words, this federal borrowing rate is the base, most other interest rates are effectively tied to that base, and therefore most interest rates tend to rise and fall with the base federal rate.
So when interest rates on the federal debt climb, interest rates on deposits, money market funds, bonds and mortgage securities all rise as well.
And when interest rates paid by the government on its debt falls, all of these other interest rates usually fall as well.
So there is a sharing of interest rates so to speak, where the interest returns received by investors very directly correlate to the interest rates paid by the government.
Which again points to the huge conflict of interest between the objectives of savers and the needs of the government.
Impact On Retirement Standard Of Living
When someone is building wealth by investing over a period of decades, there is another crucially important factor aside from the wealth-building returns, which is the lifestyle that can be afforded once one has actually retired and is drawing down their portfolio.
The graph below assumes $250,000 in retirement savings being evenly drawn down over a period of 20 years, with nothing left at the end of the 20 years. Now the higher the interest rate, naturally the more the interest income each year, which allows the principal to be drawn down more slowly. So with higher interest rates, retirees get both higher interest payments and larger average principal balances over time, which can combine to make a surprising amount of the difference.
So if we assume a 7% interest rate, as bonds have often returned over the last 40 years, the $250,000 portfolio would produce $23,598 per year in cash available for spending.
If we were to increase that rate to 10%, the annual standard of living would be almost $30,000 per year.
If on the other hand we were to drop it to 5%, the annual standard of living that could be supported from these investments would fall to $20,061.
Now the heart of the issue with very low interest rates is that if someone holds their money in short-term, high-quality investments that pay a 1% interest rate – then specifically because the federal government has suppressed interest rates to keep them down to a mere 1% – the saver's income is only $13,854 per year for those 20 years.
At a 2% rate it would be $15,289.
While this is little remarked upon, it's the incredibly important heart of the issue.
This drastic reduction in interest rates to serve the needs of a heavily indebted federal government may drop retiree incomes by 30-50% for decades relative to what they would be with longer-term average interest rates.
So tens of millions of retirement investors who are planning on supporting themselves primarily with their investment portfolios and the rewards of their many decades of disciplined savings may see their lifestyles drastically reduced – specifically because the federal debt outstanding is now approximately 19 trillion dollars.
Impact On State & Local Governments And Pensions
This destruction of investor wealth creation is also affecting the financial solvency of states, cities, school districts and other local governments across the United States. There has been wide coverage of a public pension crisis in the United States, but when low rates are taken into account, the shortfalls are far worse than reported, and could approach the catastrophic.
As explored in the analysis linked here and shown above, the issue is that state and local governments are generally still assuming very high legacy investment rates such as 7.50% for their pensions - and even with those high return assumptions, there are still drastic funding shortfalls, as shown on the far right of the graph. When we move to the left and explore the needed funding with lower returns, the shortfalls (red bars) soar upwards to an extent that could lead to major nationwide tax increases, or reductions in pension benefits - or both.
The explosive increase in the national debt has created a fundamental conflict of interest between the federal government, and state & local governments. For decades, generous promises have been made to public employees that were not paid for by taxes, but by the assumption of high future earnings into the indefinite future. The possibility of the federal debt soaring - was not even considered.
But the debt did soar - and if rates rise materially, then the national debt spirals upwards and out of control. However, if rates don't rise materially, then the solvency of every level of state and local government is threatened because of extraordinary pension shortfalls. And if the federal government bails out the pensions, then the federal debt soars - and so do the future interest payments.
There is a cruel but inescapable mathematical collision that was set off as soon as the federal debt jumped even while interest rates were pushed to historic lows. The extent of the damage is currently being hidden by pension accounting assumptions, but these highly questionable assumptions do not change the financial realities of what is happening right now and (absent major tax increases) will be building each year into the future.
Who Is Really Paying For The Debt?
Many well-intentioned older people feel very badly indeed about the massive federal debt which they believe we are leaving for our children and grandchildren to repay. And they are correct in that we are leaving tremendous financial challenges for our children and grandchildren, of which this extraordinary level of federal debt is a key component.
There are many other people who don't worry or think about the size of the national debt at all – and who have a strong desire to keep things that way. Yes, they are likely aware that the federal government owes some fantastic, almost surreal amount of money, but it doesn't seem to be affecting their personal daily lives in any way that they can see – so they just choose to ignore it.
Unfortunately, both groups of people – who comprise the great majority of the population – could not be more mistaken when it comes to the national debt being primarily a problem for the somewhat distant future.
For if we're talking about the value of the federal debt and its repayment in the decades ahead, the debt is actually far more likely to be paid in inflation (as explained here), or through a combination of inflation and artificially-suppressed interest rates (as explained here), than by our children and grandchildren toiling for decades to slowly repay the debt with dollars that have the same value as today's dollar.
Rather than being some far-off burden for our children and grandchildren to bear – the price of the massive amount of federal debt is being paid in the here and the now.
Anyone who has a retirement account is paying a price. Anyone who has or is entitled to a pension is paying the price, because that pension may very well be in financial distress now or in the future because it just can't get the interest earnings needed to meet its obligations.
Conversely – anyone who uses a loan to buy a car now or in the future is likely to benefit from low rates. As will anyone who takes out a mortgage to buy a house. Particularly for younger people who are still in a borrowing phase and have not yet reached the saving phase of life, the current low interest environment has acted to improve the quality of their lives by reducing what they pay each month in interest payments.
In some ways, the current extraordinary level of federal debt could be likened to sharing our solar system with a financial black hole. Just because people aren't seeing it every day – doesn't mean it isn't there. Whether seen or not – the massive gravitational pressure dominates everything around it.
And every time someone saves, invests, retires or makes a major purchase – the massive weight of that $19 trillion debt pulling interest rates down through the corresponding governmental interventions impacts their life in some way, right that minute.
This "black hole" can be found in other nations around the world as well, for the United States is far from alone when it comes to having huge national debts with a rapidly aging population.
While this massive weight affects every part of society, there is one group that is more affected than any other. That group is the people who are following traditional retirement planning or other conventional long-term investment strategies.
Traditional financial planning doesn't take massive federal debts into account, nor does it take into account the Federal Reserve creating money by the trillions to force interest rates downwards. Instead, investors are supposed to receive market interest rates that will reward them with a compounding of wealth before retirement, and a generous cash flow after retirement.
But if the federal government can't afford substantially higher interest rates – it could be a very, very long time before medium and high interest rates return. And if that is the case – tens of millions of people may never achieve the compounding of wealth they were anticipating for retirement, nor the level of cash flow they were counting on after retirement.
This doesn't mean that it is impossible to successfully build wealth in low interest rate environments, but rather, it is a matter of assumptions and choices. If an investor starts with the traditional assumption that interest rates will be high enough to support a desired standard of living in retirement, and interest rates turn out in practice to be a fraction of what was assumed – then the natural and expected result is that the actual standard of living experienced in retirement may be much lower than what was planned.
On the other hand, if one starts with the opposite assumption that there is a strong chance that rates may remain low for an extended time, then quite different strategies can be chosen for that environment, where the lower that interest rates are, the better the strategies perform. So that the longer the low interest rates continue, the better the long-term investor results, and the higher the resulting standard of living.
But before such choices can be made, the necessary first step is to recognize the existence of the problem. Which is, in this case, to understand that a $19 trillion federal debt is neither irrelevant to our personal lives, nor is it just an issue for the distant future – but rather it is influencing and changing each of our lives every day right now, and is likely to continue to do so for many years to come, particularly as the debt grows steadily larger.
What you have just read is an "eye-opener" about one aspect of the often hidden redistributions of wealth that go on all around us, every day.
For simplicity, the analysis on this page isolated the impact of interest rate changes, and assumed non-interest deficits remained constant. We know that won't be the case, however. The long expected surge in Boomer retirement expenses is finally upon us, and as shown above and explored in the analysis linked here, increasing benefit payments alone will lead to an increase in annual deficits of almost half a trillion dollars a year by 2020, and nearly a full trillion dollars a year by 2023. Making any future major increase in interest rate levels even more expensive, and even more unlikely.
The next level of understanding moves from savers to governments, and explores a historically proven method for reducing outsized national debts. As analyzed here, governments have now returned to using the 1-2 combination of their control over not only 1) interest rates but also 2) inflation, to actually take real wealth from private savers in order to pay down massive public debts, much like they did in the years following World War II.
The stakes are high for the government when it comes to the national debt – and that is also true of Social Security. And once again, the numbers don't quite work the way many people think. The government strongly encourages people to wait as long as possible before collecting their retirement benefits – but as explored here, is that truly in your best interest, or are a few factors being left out?
If you find these "eye-openers" to be interesting and useful, there is an entire free book of them available here, including many that are only in the book. The advantage to the book is that the tutorials can build on each other, so that in combination we can find ways of defending ourselves, and even learn how to position ourselves to benefit from the hidden redistributions of wealth.
