June 17 (Reuters) - U.S. bond funds suffered robust outflows in the week to June 15 as climbing inflation levels raised the odds of a faster pace of interest rate hikes by the Federal Reserve and spurred worries of a recession.

According to Refinitiv Lipper data, investors dumped bond funds valued at $18.73 billion, the biggest weekly net selling since March 18, 2020.

Data last week showed U.S. consumer prices accelerated faster than expected in May, leading to the largest annual increase in nearly 40-1/2 years.

The Federal Reserve on Wednesday approved an interest rate increase of 75 basis points, its biggest policy rate hike since 1994, to stem a surge in inflation that U.S. central bank officials acknowledged may be eroding public trust in their power.

U.S. investors offloaded municipal bond funds worth $5.93 billion and taxable bond funds of $12.94 billion.

They exited high yield bonds funds, general domestic taxable fixed income funds and short/intermediate investment-grade funds worth $5.87 billion, $5.41 billion and $4.74 billion, respectively.

U.S. equity funds also saw outflows worth $21.62 billion, which was the biggest weekly net selling since Dec. 15.

Investors sold U.S. large and mid-cap funds of $10.26 billion and $591 million, respectively, however, small-cap funds obtained $2.02 billion worth of inflows.

U.S. growth funds recorded a $7.95 billion worth of withdrawals in a 10th straight weekly outflow, while value funds suffered a net selling of $6.02 billion.

Among sector funds, financial, metals and mining as well as tech posted outflows amounting to $989 million, $224 million and $144 million, respectively, but utilities lured purchases of $249 million.

Meanwhile, investors withdrew $8.94 billion out of money market funds after purchases of $24.96 billion made in the previous week.
