Aug 2 (Reuters) -

Even as markets on Wednesday largely brushed off Fitch’s downgrade of U.S. debt, investors said they expected long-term market unease about the country’s debt position, political polarization and the global standing of the U.S. dollar.

U.S. stocks, bonds and the dollar were largely calm the day after Fitch unexpectedly

stripped the U.S. of its top credit rating

, saying expected fiscal deterioration over the next three years and repeated debt ceiling disputes threaten the government's ability to pay its bills.

Wall Street's three major indexes ended the day lower

, but analysts said many investors were cashing in some profits after five straight months of gains. Most major brokerages said they did not expect sustained turbulence, especially since strong U.S. economic data has calmed fears of a recession.

Yet some market participants also said the ratings cut was a reminder that the country’s fiscal picture is becoming increasingly cloudy, which could heighten worries for everyone from asset managers to global central banks and others holding massive amounts of U.S. government debt.

Fitch’s call will “cause people to stop and ask questions," said Robert Tipp, PGIM Fixed Income's chief investment strategist and head of global bonds. “The fiscal framework of the 1990s is gone, as is the budget surplus, replaced by alarmingly large deficits, along with more frequent threats of government closure, and default.”

Tipp pointed at the country’s soaring

debt to GDP ratio

, which stood at around 100% at the end of 2022. Just a decade ago, that level would have been considered in the “danger zone” for sovereign credits, he said.

Strategists at Macquarie led by Thierry Wizman said the downgrade could lend ammunition to countries calling for alternatives to the U.S. dollar's decades-long reign as the world’s premier reserve currency.

Fitch’s downgrade will likely be used at a summit of leaders from the BRICs trade bloc including Brazil, Russia, India, China and South Africa this month as a public relations ploy to help tout a new currency, Wizman wrote in a Wednesday report.

“If that matters in shaping sentiment toward the USD in the "court of global public opinion then the status of the USD just took another notch downward,” he said.

The dollar share of official FX reserves fell to a 20-year low of 58% in the fourth quarter of 2022, according to International Monetary Fund data. Still, few believe the

U.S. currency’s dominance

will be challenged anytime soon.

For now, however, many investors focused on the near term outlook for the U.S. economy, as the country looks increasingly likely to avoid a recession that had been widely expected early this year.

Josh Frost, the U.S. Treasury’s assistant secretary for financial markets, said he did not expect Fitch's announcement to hurt demand for Treasury debt.

“Treasuries remain the safest and most liquid assets in the world and we continue to see strong demand from our broad and diverse investor base,” he said.

Data released last week showed the U.S. economy grew faster than expected in the second quarter as a resilient labor market supported consumer spending, with markets now pricing in a soft-landing scenario for the economy despite rapid interest rate hikes by the Federal Reserve.

Markets also took comfort that Fitch did not adjust U.S. "country ceiling", which it affirmed at AAA, showing strength in the ability of the corporate sector to convert local currency into a foreign currency for debt repayments.

"If Fitch had also lowered the country ceiling, it could have had negative implications for other AAA-rated securities issued by U.S. entities," said Goldman Sachs economists led by Jan Hatzius.

Steven Zeng, strategist at Deutsche Bank, said Friday’s U.S. employment report could trump the downgrade news for markets.

"Investors have lived through the

S&P downgrade

in 2011 and remember coming away unscathed,” he said. Also, people may have “gotten used to an elevated level of deficit spending," he said.
