NEW YORK, June 11 — Blistering inflation is threatening to re-ignite twin declines in US stocks and bonds, leaving investors with few places to hide from a Federal Reserve that appears locked in to its most aggressive policy tightening in decades.

Yesterday gave a hint of what investors may expect in coming weeks, as the S&P 500 fell more than 2.5 per cent while yields on the benchmark Treasury hit their highest since early May after stronger-than-expected inflation data ramped up expectations for more aggressive Fed rate hikes later this year. Bond yields move inversely to prices.

"Today, the inflation data was disappointing. Many hopes for a peak are now dashed,” said Ryan Detrick, chief market strategist at LPL Financial.

"The fears over inflation and the potential impact of profits in corporate America are adding to the worries for investors here.”

Stocks and bonds have fallen in lockstep for most of the year as tighter Fed policy lifted yields and dried up risk appetite, pummeling investors who had counted on a mix of the two assets to buffer declines in their portfolios.

Those moves partially reversed over the last few weeks on hopes that a potential peak in inflation would allow the Fed to turn less aggressive later this year.

But with markets now betting policymakers will hike rates by at least 50 basis points in their next three meetings, expectations of Fed dovishness are fading and investors believe more declines are in store.

"Given that price pressures in the US show little sign of easing, we doubt that the Fed will take its foot off the brakes anytime soon,” analysts at Capital Economics wrote yesterday.

"We therefore suspect that more pain is yet in store for US asset markets, with Treasury yields rising further and the stock market remaining under pressure.”

The S&P is down 18.5 per cent year-to-date, again approaching the 20 per cent decline from record highs that many investors consider a bear market.

Yields on 10-year US government bonds — a benchmark for mortgage rates and other financial instruments — have more than doubled.

Phil Orlando, chief equity market strategist at Federated Hermes, has beefed up cash positions in the portfolios he manages to 6 per cent — the largest allocation he’s ever held — while cutting holdings in bonds. In equity markets, he is overweight the sectors expected to benefit from rising prices, such as energy.

"You have a very difficult picture for financial markets for the next several months,” he said. "Investors (have) to accept that the consensus view was wrong and inflation is still a problem.” Orlando sees fears of stagflation — a period of slowing growth and high inflation — as the market driver.

Overall, 77 per cent of fund managers expect stagflation in the global economy over the next 12 months, the highest level since August 2008, according to a survey by BoFA Global Research taken before yesterday's inflation data.

That white-hot print — which showed consumer prices rising 8.6 per cent in May — is pushing some Wall Street banks to raise forecasts for how much the Fed will need to hike rates to staunch inflation in coming months, potentially maximising the pain for investors.

Barclays now sees policymakers delivering their first 75 basis-point increase in 28 years when they meet next week, while Goldman Sachs strategists forecast 50 basis-point hikes at each of the next three meetings, in line with what markets were pricing yesterday.

The Fed has already raised rates by 75 basis points this year. FEDWATCH Meanwhile, few investors expect falling equity markets to knock the Fed from its inflation-fighting path.

A BoFA Global Research poll taken before yesterday's CPI number showed that 34 per cent of global bond investors believe the central bank will ignore equity weakness entirely, only pausing if markets become dysfunctional.

Pramod Atluri, fixed income portfolio manager at Capital Group and Principal Investment Officer on Bond Fund of America (BFA), is among the bond investors who have dialled back duration — which is a portfolio sensitivity to changes in interest rates — over the last few weeks.

"I thought there was a reasonable chance that inflation had peaked at 8.5 per cent, and we would be on a steady downward trend through the rest of this year. And that has not played out,” Atluri said.

"We’re now back to a point where we’re wondering if two 50 basis point hikes and maybe a third 50 basis point hike is enough.” — Reuters
