U.S. stock indexes fell Monday as rising Treasury yields, which move inversely to stock prices, sent technology stocks tumbling.

Investors are preparing for Tuesday’s release of U.S. inflation data for March, which many expect to show the highest price increases in 4 decades.

However, the labor market is also at multi-year highs in terms of full employment as the economy recovers from pandemic-era shutdowns.

Tuesday’s data release will be the last time the Federal Reserve sees official consumer price index data before its May meeting, when it is expected to raise rates by half a point rather than the usual quarter-point.

The price of oil has fallen to about $94 a barrel, which could be a sign that inflationary pressures of the past few months are nearing a peak. If energy prices fall enough, fuel and consumer goods prices will eventually be affected.

In addition, the wave of earnings reports from large companies begins this week as the first quarter reporting season kicks off. Major banks are due to start reporting on Wednesday, and other S&P 500 companies are on the docket as well.

The U.S. stock market is closed on Friday due to a holiday, so investors are in for a shortened trading week.

Here are 3 events that could affect the market on Tuesday:

1. CONSUMER PRICES

The US will release Consumer Price Index (CPI) data on Tuesday at 08:30 am ET (13:30 GMT). In comparison, year-over-year growth of 8.4% is expected after a 7.9% increase in February. Meanwhile, according to analysts at Investing.com, CPI for March is expected to come in at 1.2%, up from 0.8% in the previous month.

2. CORE INFLATION.

The core CPI for the month, which measures changes in the prices of goods and services excluding food and energy, is projected to be 0.5% in the U.S. in March, the same as in February.

3. FRS SPEAKERS’ SPEECHES

Fed vice chair nominee Lael Brainard will speak on Tuesday. Brainard said last week that the Fed could begin rapidly shrinking its balance sheet as early as May. Brainard, along with Fed chief Jerome Powell, are still awaiting her confirmation by the Senate.
