NEW YORK (Reuters) – Investors in financial derivatives called U.S. inflation swaps are betting that President Donald Trump’s tariffs will have a hefty short-term impact on consumer prices that will recede in the next few years as recession concerns escalate.

Inflation swaps are used to hedge against a rise in prices. They have two participants: the receiver and payer. The receiver seeks protection against rising inflation, while the payer, typically a bank, assumes the risk tied to inflation.

Specifically, the receiver agrees to exchange with the payer a fixed amount for floating payments tied to the Consumer Price Index (CPI) for a given notional amount and period of time.

These instruments are also used by market participants to speculate on the path of inflation and more broadly to infer inflation expectations. U.S. inflation swaps cleared by LCH have amounted to $1.3 trillion so far this year, having grown sharply since Trump’s January 20 inauguration in the face of rising tariff uncertainty.

Trump is expected to announce on Wednesday a wide range of reciprocal tariffs against U.S. trading partners who levy tariffs against imports from the United States. While there are no specific details on which products will be affected, analysts expect that tariffs will be imposed on cars, semiconductors, lumber, and pharmaceuticals.

The U.S. president, however, said last week, he was open to negotiating deals with countries seeking to avoid U.S. tariffs.

Ahead of this tariff announcement, U.S. one-year inflation swaps surged to a two-year high of 3.07% on Friday, and were last at 2.99% on Tuesday. This move means that investors believe headline CPI will average about 3% over the next 12 months, higher than the 2.8% year-on-year CPI reading for February, the latest available data.

U.S. two-year swaps, on the other hand, were at 2.84%, while those on three-year maturities stood at 2.42%, LSEG data showed, suggesting the market thinks inflation will come down after that initial spike.

“There’s an initial, one-time increase in inflation at the price level because firms have to raise prices to offset the impact of tariffs,” said Ryan Swift, chief bond strategist at BCA Research.

“But over the medium term, tariffs would actually slow manufacturing activity, which means less demand … and inflation will end up lower than what it would have been otherwise just because the economy is hurt. It reflects recession expectations.”

Recession is not the base case for many banks, although that likelihood has increased.
