A blue wave swept across Washington
Summary
- The Democrats have won control of both the House of Representatives and the Senate in the US midterm elections, leading to increased oversight and regulation but unlikely major changes in economic policy.
- A Democrat-majority Senate would maintain the independence of monetary policy, reducing political pressure on the Federal Reserve regarding interest rate cuts and banking regulations.
- Increased investigations and regulatory risks are expected for banks, tech giants, and oil companies, with potential impacts on AI infrastructure investments due to political opposition and construction bans.
- The agricultural and biofuel sectors may benefit from stricter blending mandates, supporting demand for corn and soybeans, while the stock market's direction will be influenced by the 10-year yield, oil prices, and AI investment returns.

The Democrats are taking victory in both the House of Representatives and the Senate in the US midterm elections. This would mean increased oversight and regulation, but major changes to the broad lines of economic policy are unlikely. Dissatisfaction with personal finances decided the election this time.

From the market's perspective, the most central consequence would be the preservation and emphasis of the independence of monetary policy: a Democrat-majority Senate would loosen Trump's grip on the Fed. To the seven-member Board of Governors, Trump has appointed three central bankers so far, and he would not secure a majority on the central bank's board without a newly vacant seat before Powell's term ends in early 2028. This would decrease the risk of political pressure for interest rate cuts as well as for the easing of banks' capital requirements and regulation of the crypto and fintech sectors.
For the corporate sector, the most significant change would be an increase in investigations and subpoenas, particularly in banks, tech giants, and oil companies, and with Democrat Elizabeth Warren potentially taking the helm of the Banking Committee, the regulatory risk for the financial sector would clearly increase, WSJ reports. Regarding AI investments, the construction of data centers faces growing political opposition, and state-level construction bans in Texas, Georgia, and Michigan would act as a concrete brake on the infrastructure cycle. For instance, tech investor Brad Gerstner stated according to WSJ: "We may see that at least 10–15 gigawatts of expected construction capacity fails to come online. Therefore, I believe that investing in AI infrastructure will become extremely challenging." Because of this, it was no wonder that the market's initial reaction was negative.
On the positive side, the agricultural and biofuel sectors would likely benefit from stricter blending mandates, which would support the demand for corn and soybeans. Overall, a "blue wave" would mean a tightening of the regulatory and oversight environment for the economy rather than a fiscal turnaround.
The post-midterm period has typically been positive for the stock market, as I mentioned in yesterday's macro comment. It is still worth remembering that the direction of the stock markets for the rest of the year will be determined by the 10-year yield, which has risen to nearly 5%, oil prices that have climbed to six-month highs, and the returns on AI investments.
