Deutsche Bank's argument, if it plays out, points to further upside risk in bond yields and continued pressure on rate sensitive assets, since current pricing implies only two more Fed hikes by July 2027 despite what the bank frames as intensifying inflationary pressure. Equities are not necessarily the casualty in this scenario. Allen's own comparison to 1999, when the Fed hiked, yields rose and the S&P 500 still gained close to 20%, suggests strong growth and hiking cycles can coexist for a period. The bigger risk in Allen's framing is timing: he argues something has to give between currently resilient risk assets and a tightening path that ends up going further than markets expect, which would matter most for credit spreads and equity valuations if the adjustment comes abruptly rather than gradually.---Deutsche Bank says the market's confidence that only a couple more rate hikes are coming may be exactly the kind of complacency that preceded past tightening cycles running further than expected.Summary:Deutsche Bank strategist Henry Allen said in a note that investors are underestimating the scale of rate hikes needed to bring inflation under control, describing a "fundamental dislocation" between market pricing and building inflationary pressure.Interest rate swap pricing currently implies only two further Fed rate hikes by July 2027, despite Fed Chair Kevin Warsh acknowledging inflation has run above target for more than five years.Allen pointed to rising oil, gas, food and metals prices and an ISM services index signalling input cost pressure last seen when US CPI ran near 5%.He said financial conditions remain unusually loose for this stage of a tightening cycle, citing the S&P 500 near record highs and tight credit spreads, meaning more hikes could be required to actually curb inflation.Allen argued markets have historically underestimated rather than overestimated the scale of hiking cycles, citing 2022, when investors initially priced 200 basis points of Fed hikes in the first year, but the Fed ultimately delivered more than 400.He said strong growth does not necessarily mean rate hikes derail equities, pointing to 1999, when the Fed hiked, yields rose and the S&P 500 still gained close to 20% that year.Separately, Deutsche Bank described a "globally synchronised rate hiking cycle" taking shape across the Fed, ECB and Bank of Japan, tied to commodity price trends pushing inflation higher.Deutsche Bank strategist Henry Allen has warned that financial markets are underpricing how far central banks may need to raise interest rates, arguing there is a widening gap between current pricing and the inflationary pressures building across major economies. In a note, Allen described a "fundamental dislocation" between market expectations for only modest further tightening from the Federal Reserve and European Central Bank and the scale of the price pressures both institutions are facing.Interest rate swap markets currently imply just two additional Fed rate hikes by July 2027. Allen contrasted that pricing with Fed Chair Kevin Warsh's own acknowledgment that inflation has run above target for more than five years without meaningful improvement. He pointed to a broader set of inflationary signals supporting his view, including rising oil, gas, food and metals prices, alongside an ISM services index showing input cost pressures at levels last seen when US CPI inflation was running near 5%. Allen also argued that financial conditions remain unusually accommodative for this stage of a tightening cycle, noting the S&P 500 trading near record highs and credit spreads holding tight, both of which he said suggest more aggressive rate hikes may ultimately be required to bring inflation down.Central to Allen's argument is a historical pattern he says investors consistently overlook. He noted that markets tend to underestimate rather than overestimate the scale of hiking cycles once they begin, pointing to 2022 as the clearest recent example, when investors initially priced in 200 basis points of Fed rate increases over the following year, only for the Fed to ultimately deliver more than 400 basis points of tightening. He also said central banks tend to overcorrect for the mistakes of the previous cycle, and are already responding more aggressively this time than in 2022, when the Fed did not begin hiking until inflation had climbed above 8%.Allen was careful to note that a more aggressive hiking path would not necessarily be disastrous for equities, provided economic growth holds up. He pointed to 1999 as a precedent, when the Fed raised rates and bond yields rose in tandem, yet the S&P 500 still posted gains of close to 20% for the year. Still, he cautioned that the current combination of resilient risk assets and a potentially longer tightening path cannot persist indefinitely, warning that sustained pressure on rates would eventually force an adjustment in risk assets more broadly, with several asset classes vulnerable to a more aggressive tightening cycle than markets currently anticipate. Separately, Deutsche Bank analysts described the broader environment as a "globally synchronised rate hiking cycle" taking shape across the Fed, European Central Bank and Bank of Japan, tied to commodity price trends the bank expects will continue pushing inflation higher across major economies.
