What are the light and shadow of the economy indicated by rising interest rates? How to determine if it is a sign of a boom or a harbinger of a recession
💪 Global long-term interest rates: From a quiet warning to a clear risk
The global bond market is now exuding a different kind of tension than before. The rapid and sustained rise in long-term interest rates is making anxieties about economic breaking points and debt crises feel increasingly real. Interest rates are not usually at the center of the news. However, the changes happening behind the scenes are quietly and powerfully rippling through home mortgages, corporate financing, national fiscal management, and investor asset allocation. This movement cannot be dismissed as mere temporary market volatility. It suggests that the premises of the global economy, which have long been supported by low interest rates, may be starting to crumble.
In early October, the U.S. 10-year Treasury yield reached 5.30%. This is an increase of over 400 basis points compared to the beginning of 2020, and more than 100 basis points higher than at the start of the year. Basis points are a unit for measuring changes in interest rates, where 1 basis point is equivalent to 0.01%. In other words, over 400 basis points means an increase of more than 4%, and over 100 basis points means an increase of more than 1%. While these might look like cold statistics, the reality behind them is very heavy. It means the phase is shifting from an era where funds could be borrowed at low rates to an era where appropriate costs and resolve are required for financing.
Similar movements have been confirmed in France. French government bond yields rose by more than 160 basis points between March and October, reaching 4.91%. Such a change in just a few months is quite large for normal times. Moreover, this is not just about France. The rise in long-term interest rates in the U.S., Europe, and major global markets is affecting the psychology of investors, policymakers, corporate executives, and households. Rising interest rates visibly increase the burden on households and businesses, while simultaneously rebounding on government debt repayment costs. The fact that market interest rates are rising means that low-interest debt issued in the past could turn into a heavy burden when refinanced in the future.
🔥 The rise in long-term interest rates is not someone else’s problem
Long-term interest rates are critical prices that incorporate expectations and risks for the future. Various factors, including economic outlooks, price trends, central bank policies, fiscal sustainability, and even geopolitical anxieties, are reflected in long-term interest rates. That is precisely why a sharp rise in long-term interest rates is not just a problem for the bond market. For those looking to buy a home, rising mortgage rates become a factor that squeezes repayment plans. For companies, the cost of capital investment, acquisitions, and working capital increases. For governments, the burden of issuing and refinancing government bonds increases, narrowing the freedom of fiscal policy. For investors, the premises for evaluating asset prices such as stocks and real estate change, forcing a review of portfolios.
What is particularly concerning is that interest rate hikes permeate slowly and, one day, suddenly affect the funding of households, businesses, and governments. Once interest rates rise, they do not immediately affect all existing debt in the same way. Fixed-rate loans do not change immediately, and refinancing timings vary. However, as time passes, there are more situations where funds must be raised at higher interest rates. This accumulation erodes household disposable income, lowers corporate profit margins, and inflates government interest payments. Because it takes time to surface, early inspection is essential.
Furthermore, the rise in long-term interest rates affects currency and capital flows. Funds tend to gather in countries with high interest rates and leave countries with low interest rates. As a result, exchange rates move, which ripples into import prices, the profitability of export companies, and capital outflows from emerging countries. In a phase where global interest rates are rising simultaneously, each country faces pressure in the same direction, despite their individual circumstances. It is as if the steering wheel of interest rates is being turned globally at the same time. Moreover, it is not just one country’s central bank holding that wheel. Multiple factors are intertwined, including fiscal credibility, political stability, energy prices, and the international situation. That is why there is no simple prescription, and careful assessment is required.
⚡ Why anxiety about a debt crisis is rearing its head again
The rise in long-term interest rates hits hardest in countries with large debt balances or those carrying fiscal deficits. Until now, thanks to low interest rates, interest payment burdens could be kept down even with large amounts of debt. However, as interest rates rise, the conditions for issuing government bonds deteriorate, and the possibility of paying high costs with each refinancing emerges. Even in situations where one wants to increase fiscal spending, the increase in interest payments reduces the capacity available for new policies. In household terms, this is similar to a situation where the proportion of income spent on repayments increases, reducing the freedom of life. The same thing is happening at the national level.
The term ‘debt crisis’ might sound a bit exaggerated. However, when the market begins to feel anxious, the rise in government bond yields itself can become self-reinforcing. Interest rates rise, interest payment burdens increase, concerns about fiscal health intensify, and interest rates rise further. Once in this cycle, governments are forced to make difficult choices such as tax hikes, spending cuts, or new borrowing. Of course, not all countries fall into the same crisis at the same time. Resilience varies depending on economic growth rates, the currency composition of debt, central bank credibility, and political stability. Even so, if the rise in interest rates is prolonged, the likelihood of previously hidden vulnerabilities surfacing increases.
For companies, rising interest rates also change the premises for financing. Companies that have built business plans based on low-interest borrowing need to incorporate the rise in interest costs. In particular, for companies with high dependence on borrowing, unstable cash flow, or those facing refinancing in the short term, the impact of rising interest rates is likely to be significant. For investors, interest rates are like a yardstick for measuring asset prices. If interest rates rise, the rate used to discount future profits to present value increases, which can lead to adjustments in the valuation of stocks and real estate. That is why operations that ignore interest rate movements are dangerous. It is important to adopt a stance of checking not just the stock prices or real estate prices in front of you, but the interest rate environment behind them.
💪 So, what should we look at and how should we prepare?
First, I want to confirm the meaning of the U.S. 10-year Treasury yield reaching 5.30%. This indicates not just the height of the level, but that it has risen at a speed of over 400 basis points since the beginning of 2020 and over 100 basis points since the start of the year. Along with the level of interest rates, attention must also be paid to the speed of the rise. Rapid interest rate hikes force market participants to adjust positions, which can lead to declines in bond prices and fluctuations in stock prices. In particular, investment strategies and business plans based on low interest rates may need to be reviewed.
Next, the fact that French government bond yields rose by more than 160 basis points between March and October to reach 4.91% cannot be overlooked. The rise in European interest rates is easily linked to issues such as regional economic disparities, fiscal discipline, and the durability of the banking sector. The degree of impact from rising interest rates varies depending on each country’s fiscal situation and political circumstances. That is why it is necessary to look not just at one country’s figures, but also at interest rate differentials with neighboring countries, market reactions, supply and demand for government bond auctions, and currency movements. Interest rates are numbers, but behind them are the expectations and anxieties of market participants. Reading the story behind the numbers is essential for future judgment.
For households, I want to re-examine plans for mortgages, education funds, and retirement funds. If you have a variable-rate loan, it is important to specifically calculate the repayment amount when interest rates rise. When considering switching to a fixed rate, it is necessary to comprehensively judge fees, periods, and future interest rate outlooks. For companies, I want to confirm the interest conditions of borrowings, repayment deadlines, and cash flow durability, and conduct stress tests in case interest rates rise further. For governments and local municipalities, it is necessary to scrutinize the impact of increased interest payments on the budget and clarify fiscal priorities. For investors, it is required to review the balance of bonds, stocks, real estate, and cash, and organize assets that are strong and weak against rising interest rates.
🔥 What is needed in the era of interest rates is preparation that does not procrastinate
The sharp rise in long-term interest rates stirs anxiety about economic breaking points and debt crises. However, just holding onto anxiety changes nothing. What is important is to proceed with preparations in each area of households, businesses, investments, and fiscal policy, assuming the possibility that interest rates will remain at high levels. Interest rates are like a mirror reflecting future risks. If you look directly at the changes reflected in the mirror, you can take action early. Conversely, if you spend time with the sensibilities of the low-interest-rate era, you may suddenly face an increase in repayment burdens or financing costs one day.
First, I want to start by grasping your own funding and asset situation with numbers. Write down your monthly repayment amount, outstanding loan balance, type of interest rate, refinancing timing, cash reserves, and income stability. If you are a company, calculate how profits and cash flow will change if interest rates rise by 1% or 2%. If you are an investor, identify assets whose valuations are likely to change during a phase of rising interest rates, and reconfirm diversification and risk management. If you are a policymaker, it is important to calculate the impact of rising interest rates on fiscal policy over the medium to long term and not neglect dialogue with the market.
Global long-term interest rates are no longer statistics of a distant country. When choosing a mortgage, thinking about business borrowing, deciding on investment policies, or discussing national fiscal policy, they affect everything. U.S. 10-year Treasury yield 5.30%, over 400 basis points higher than early 2020, over 100 basis points higher than the start of the year. French government bond yields rose over 160 basis points from March to October to 4.91%. These numbers tell the story of the speed and magnitude of change. Now is the time not to dismiss rising interest rates as temporary noise, but to think specifically about what they mean for your household, work, investments, and the fiscal foundation of society. Not procrastinating on preparation is the first step to surviving the uncertain era of interest rates.
