A week defined by central bank caution and geopolitical risk
The week of 16–20 March 2026 was shaped by a rare combination of synchronized policy restraint and elevated geopolitical stress. The Federal Reserve, European Central Bank, Bank of England, Bank of Japan, and Swiss National Bank all left interest rates unchanged, highlighting how policymakers are now caught between renewed inflation pressure from energy and a broader growth outlook that is losing momentum. At the same time, the war in Iran and uncertainty around the Strait of Hormuz remained the dominant macro risk in global markets.
Oil continued to sit at the center of market pricing. Even though crude pulled back from its recent highs at points during the week, Brent remained near the USD 97–100 range, and WTI stayed volatile after having surged above USD 100 the previous week. That backdrop kept investors focused on inflation risks, rate expectations, and the growing possibility that global growth could slow more sharply if the energy shock persists.
Monday: Wall Street rebounds as oil eases
Markets began the week on a more constructive footing. Wall Street rebounded after three consecutive weeks of losses, helped by a temporary pullback in oil prices. The S&P 500 rose 1.01% to 6,699.38, the Dow Jones gained 0.83%, and the Nasdaq advanced 1.22%, recording its strongest session in five weeks.
Technology also offered some support to sentiment. NVIDIA opened its GTC 2026 conference in San Jose, with CEO Jensen Huang introducing the Vera Rubin platform and projecting USD 1 trillion in orders through 2027 across Blackwell and Vera Rubin systems. That announcement helped lift the stock and gave markets a positive counterweight to the broader geopolitical stress. Meanwhile, the United States also announced efforts to build an international naval escort coalition for the Strait of Hormuz, although negotiations were still ongoing.
Tuesday: cautious gains ahead of the Fed
Risk appetite remained fragile on Tuesday. Equity markets managed modest gains ahead of the Federal Reserve decision, but oil resumed its upward move. The S&P 500 added 0.25% to 6,716.09, the Nasdaq rose 0.47%, and the Dow gained 47 points.
The energy complex remained one of the clearest market winners. Brent crude jumped 3% and consolidated above USD 100 per barrel, while WTI settled above USD 96. Energy shares, including APA, BP, ConocoPhillips, and Devon Energy, reached fresh highs, while sector ETFs such as XLE and VDE touched record levels. NVIDIA’s conference remained in focus, and Bank of America reiterated a buy rating on SAP, emphasizing the appeal of defensive quality in an increasingly unstable market environment.
Wednesday: the Fed holds, but Powell keeps markets uneasy
Wednesday was the pivotal session of the week. The Federal Reserve left the federal funds rate unchanged at 3.50%–3.75% in an 11–1 vote, with Governor Miran dissenting in favor of a cut. While the decision itself was widely expected, the broader message was more restrictive than markets had hoped.
The updated dot plot pointed to a median of only one rate cut in 2026, and seven of the nineteen participants expected no cuts at all this year. At the same time, Fed projections raised PCE inflation to 2.7% and GDP growth to 2.4%. Chair Powell emphasized that inflation had not improved as hoped and said the war in Iran was adding substantial uncertainty to the outlook. Equities weakened after his press conference, reflecting concern that rates could stay higher for longer in a riskier macro environment.
Geopolitical headlines also darkened the backdrop further. Israel reported that it had killed Iran’s top security official, while the Islamic Republic struck a natural gas field in the United Arab Emirates, intensifying fears of broader regional escalation.
Thursday: a rare global pause from four major central banks
Thursday delivered one of the most remarkable policy sessions of the year, with four major central banks all leaving rates unchanged. The ECB kept its deposit facility rate at 2.00% and its main refinancing rate at 2.15%. President Lagarde revised the 2026 inflation forecast to 2.6% and downgraded GDP growth to 0.9%, explicitly warning about risks linked to the Iran conflict.
The Bank of England also held Bank Rate at 3.75%, and this time the decision was unanimous at 9–0, a sharp contrast to February’s 5–4 split. The MPC stressed the burden that higher energy prices place on households and businesses. At the same time, European natural gas prices surged 25%, and the UK 10-year gilt yield climbed to 4.87%.
In Asia, the Bank of Japan held rates at 0.75% in an 8–1 vote, with Takata dissenting in favor of a hike to 1.0%. The BoJ flagged upside inflation risks tied to oil, while USD/JPY traded in the 158–159 range. The Swiss National Bank left its rate at 0.00% and signaled a stronger willingness to intervene in foreign exchange markets to limit Swiss franc appreciation.
Friday: markets end the week in risk-off mode
By Friday, markets were digesting the combined impact of hawkish holds from central banks and still-elevated geopolitical risk. The S&P 500 was down 0.73% by mid-morning and was on track for a fourth consecutive weekly decline. Market regime models showed the implied probability of recession rising to 35%, up from 10% just two weeks earlier.
Oil remained volatile rather than decisively lower. WTI traded around USD 93.55, off weekly highs but still elevated, while Brent fluctuated in the USD 97–100 range. The 10-year US Treasury yield hovered near 4.27%. European equities posted broad losses, while South Korea’s KOSPI suffered a dramatic 12% intraday plunge, underscoring how fragile sentiment had become by the end of the week.
