These are supposed to be the most important factors in determining a country’s creditworthiness. Risk premium over inflation is critical, while currency risk can affect foreign currency returns. Economic growth factors will also indicate whether a country can grow fast enough to be able to service its debts.
Brazil outperforms Finland on all of these metrics, and yet Brazil’s government has to pay 9.9% in interest on its two-year bonds, while Finland’s two-year bonds yield just 2.9%. The same applies to Brazil’s BB credit rating and Finland’s AAA rating.
Quantitative easing
One possible explanation for these disparities is that countries with currencies that are used as foreign exchange reserves can monetize their debts through quantitative easing (QE), which means that the risk of debt default is lower because central banks banks can “print” money and use that liquidity to buy government bonds at will.
But QE comes with inflationary risks and suggests that G7 central banks could continue to implement monetary policy more easily than countries such as Zimbabwe and Argentina without facing negative consequences. Even in the US, whose dollar remains the world’s dominant reserve currency, QE is still fraught with risks.
Inflation has surged to multi-decade highs in the US following pandemic-era fiscal and monetary measures. When the Fed raised interest rates to contain the inflation it was largely responsible for fueling, it hurt the value of long-term US bonds and resulted in the collapse of many major banks.
Similarly, the Bank of England was forced to intervene in the debt market as higher interest rates caused significant losses to UK pension funds, delaying much-needed credit tightening, while the Bank of Japan opted to sell foreign reserves to defend the yen rather than risk raise interest rates excessively.
Loose fiscal and monetary policy in the EU and UK has been accompanied by sharp depreciations in the euro and sterling, while gold and bitcoin, which serve as hedges against fiat currencies (those issued by central banks), have rallied at record highs.
Similar policies in Japan have driven the yen’s real current exchange rate to record lows. This suggests that developed countries may find it difficult to continue to manage their public debts through monetary policy without experiencing the risk of currency depreciation and higher inflation rates.
Japan’s practice
The Japanese example is illustrative. The country’s central bank is the largest holder of Japanese government debt and corporate bonds. This lowered debt servicing costs but weakened gen. Extremely low interest rates have also created uncompetitive “zombie” companies, reducing Japan’s share of world trade.
Having run a trade surplus for decades, Japan has significant foreign exchange reserves (almost $1.2 trillion) with which to defend the yen, but other G7 nations such as the UK (under $200 billion) and the US (under $40 billion). they do not hold significant reserves to defend their currencies.
Unconventional monetary interventions
After all, few developing countries would be willing or able to resort to historically unconventional monetary policy interventions like QE, and many have arguably better economic fundamentals than current credit ratings suggest.
The BRICS group therefore wants to develop its own credit rating agencies to complement recent efforts to de-dollarize global trade and development finance.
Meanwhile, debt-challenged emerging markets will continue to argue rationally that high debt servicing costs cause rather than reflect the risk of sovereign defaults, trapping economies in the long run.
