Markets Rally on Cooling Inflation and Strong Bank Earnings
Strong bank earnings and encouraging inflation data propelled markets higher on January 15, with the S&P 500 climbing 1.83% to close at 5,957.68—its strongest session since November. The rally reflected growing optimism that the Federal Reserve's battle against inflation may be succeeding without derailing economic growth.
December's Consumer Price Index (CPI) report showed core inflation rising 3.2% year-over-year, down from 3.3% in November and beating economists' expectations. This data, combined with last week's softer Producer Price Index (PPI) reading, suggests the Fed may have room to continue cutting interest rates in 2025 while keeping inflation in check.
"Today's CPI print gives the Fed more confidence that their policy actions are working as intended," noted Janet Thompson, Chief Market Strategist at Capital Research. "While we're not completely out of the woods on inflation, the trend is clearly moving in the right direction."
The banking sector led market gains after several major institutions reported better-than-expected fourth-quarter results. Goldman Sachs jumped 6% after posting $4.11 billion in profit, exceeding analysts' expectations. Citigroup and Wells Fargo each added more than 6% on strong earnings, while JPMorgan Chase, which reported a 12% rise in quarterly profit, gained 2%.
Technology stocks also participated in the broader rally, with the tech-heavy Nasdaq Composite surging 2.45%. Industry giants including Tesla (+2.93%), NVIDIA (+2.67%), and Microsoft (+0.88%) all finished higher as lower Treasury yields improved the outlook for growth stocks. The benchmark 10-year Treasury yield dropped to 4.66%, its largest single-day decline since August.
"Lower yields make future earnings of growth companies more valuable in today's terms," explained Michael Roberts, Portfolio Manager at Maven Investments. "This environment is particularly favorable for tech stocks."
North of the border, the S&P/TSX Composite Index rose a modest 0.08% to close at 24,555.34, weighed down by weakness in energy producers despite gains in financial heavyweights. Since the start of 2025, the Canadian benchmark has declined 0.71%, underperforming its U.S. counterparts.
Looking ahead, market participants will closely watch this week's retail sales data and initial jobless claims for further clues about economic momentum. The earnings calendar remains packed, with United Airlines and Alcoa reporting Wednesday, followed by Netflix and Procter & Gamble on Thursday.
"We're entering a critical period where companies need to demonstrate that their fundamentals justify current valuations," said Roberts. "While today's rally is encouraging, investors should remain selective and focused on quality as we navigate what could be a volatile earnings season."
Potential headwinds include ongoing geopolitical tensions and uncertainty surrounding the upcoming U.S. presidential administration's policy shifts. However, if inflation continues to moderate and corporate earnings remain resilient, markets appear well-positioned to build on their recent gains.
For retail investors, the current environment suggests maintaining a balanced approach—taking advantage of opportunities in both growth and value sectors while keeping adequate cash reserves for potential market volatility. With the Fed likely to remain data-dependent in its policy decisions, staying informed about key economic indicators will be crucial for navigating the markets in the weeks ahead.
