How Wall Street Could Wreck The GOP’s Tax Cut Plans

Republicans’ plan to extend and expand the massive tax cuts for the wealthy and corporations they originally passed in 2017 are at the heart of President-elect Donald Trump’s domestic agenda.

But one of the sleepiest corners of Wall Street is flashing warning signs about the GOP’s plans: the bond market.

The Federal Reserve has been cutting the interest rates it controls, which usually results in lower market rates for loans, mortgages and credit cards. But investors holding U.S. debt have demanded increasingly higher returns on their investments, which has kept the Fed’s actions from having much effect and mortgage and credit card rates stubbornly high.

“The bond market is sending a message that investors are worried about the economic policies dead ahead,” Mark Zandi, chief economist at Moody’s Analytics, told HuffPost.

The rate for a 10-year U.S. bond, the benchmark many interest ratesare based on, has drifted upward significantly since Nov. 5, when Donald Trump was elected to his second term, from around 4.29% to 4.76%.

And it’s not alone. The 20-year bond yield has risen from 4.57% to 5.03% and the 30-year bond has gone from 4.45% to 4.95%.

These rates have steadily increased even thoughthe Federal Reserve has cut interestthree times since September, and even as shorter-term debt rates have been stable.

Stocks generally grow in valueas the economy moves faster, butbond values are tied to inflation. Higher inflation, usually accompanied by faster economic growth, makes bonds worth less, while lower inflation increases their value. So while stocks initially rose for the first few weeks after Trump’s election victory, on hopes for better economic growth, bond values went the other direction, because many of the policies Trump has said he’ll pursue will likely drive inflation up, too.

For example, stricter immigration controls or mass deportations could increase businesses’ labor costs. And tax cuts would increase budget deficits and boost the amount of debt issued by the government, making existing debt less valuable.

“I think there’s just a high level of uncertainty with regard to all that, that also is causing consternation among investors, resulting in them asking for a higher interest rate to compensate for the perceived risk,” Zandi said.

Zandi’s not alone in noting the creep upward in longer-term rates. Douglas Holtz-Eakin, president of the conservative American Action Forum and an economic adviser to John McCain in the 2008 presidential election, noted in a blog post the rise could mean two things.

It could mean investors are thinking interest rates in general are going to be higher, no matter what the Fed does in the short term. Or at least some investors are worriedabout the U.S.’ ability to pay its debts.
