By CCN.com: The Dow and broader U.S. stock market returned to strength on Tuesday after the Commerce Department temporarily rolled back trade restrictions against Huawei, the Chinese telecommunications giant. But beneath the surface, the U.S. economy is showing signs of persistent weakness that could come back to haunt the bull market.

U.S. Home Sales Decline Unexpectedly

Existing Home Sales Down 14 Straight Months, But Probably Nothin’! https://t.co/3Cn1GhreKk pic.twitter.com/FvMJ2UYqEk — David Stockman (@DA_Stockman) May 21, 2019

America’s flailing housing market showed further signs of weakness last month as existing home sales fell unexpectedly.

Home re-sales, which account for the lion’s share of the domestic real estate market, declined 0.4% in April to a seasonally adjusted annual rate of 5.19 million, the National Association of Realtors (NAR) reported Tuesday. Analysts in a median estimate called for home sales to climb 2.7%.

The housing market has been a perennial under-performer during the Trump era, as rising home costs have outpaced a surging labor market and higher wages. What’s most troubling about the April slowdown was that homebuyers don’t seem to be benefiting from declining mortgage rates.

As the following chart illustrates, fixed-rate mortgages across all time periods have declined substantially since November, which was just before the Federal Reserve initiated its fourth interest rate hike of 2018:

The Federal Reserve’s benchmark interest rate impacts mortgage costs indirectly as banks and other lenders pass on the higher cost of borrowing to consumers.

The U.S. central bank has all but abandoned its plan for additional rate hikes following the December flash crash in U.S. equities. A two-speed economic recovery, as evidenced by the recent drop in industrial production and consumer spending, is also keeping policymakers on the sidelines for now.
