Powell’s Battle-Ready Fed Gives the Trump Trade a Stress Test

(Bloomberg) — A month ago, all anyone in markets could talk about was Donald Trump and how his blueprint for the US economy would sow growth, next year and beyond.

Heading into the Christmas break, a no-less-formidable force has retaken the stage: Jerome Powell. The Federal Reserve chair’s hawkish turn this week put inflation back on the map as investors’ obsession of choice, spurring the biggest moves — up and down — since just after Election Day.

First it was Wednesday, when Powell voiced waning enthusiasm for interest-rate cuts and sent stocks and bonds to their worst sessions in months. Then moods improved significantly two days later, when the Fed’s preferred inflation gauge showed prices rising less than forecast, spurring a cross-market rally that helped trim the S&P 500’s weekly loss.

Feeding the extreme moves is high-conviction positioning, much of it by investors wagering the Trump trade has further to run in risky assets. Allocations to US equities jumped to a record while cash holdings all but evaporated, according to Bank of America Corp.’s global fund manager survey. Even systematic players such as volatility-controlled funds were piling into stocks.

The gyrations are a reminder that while it was Trump who sent speculative spirits soaring, the trajectory of inflation — and Powell’s reaction to it — loom just as large in markets where hand-over-fist buying has sent measures of valuation to extreme levels. Even with Friday’s rebound, the benchmark US equity gauge slid about 2% over the five days, while post-election stalwarts like small caps and value stocks slid a third week.

“Investors found themselves thinking that the Fed would lower rates, no matter what,” said Sameer Samana, senior global market strategist at Wells Fargo Investment Institute. “The disappointment was that the Fed finally woke up to the fact that inflation had stopped coming down.”

For now the last remnant of the Trump trade is the leg that many investors wanted least: rising bond yields. Rates on 10-year US Treasuries jumped to the highest in seven months. Driving the move were diminishing bets on interest-rate cuts after Wednesday’s Fed meeting, at which officials predicted fewer would be appropriate given inflation’s nagging presence.
