Last week, the US and Iran signed a memorandum of understanding that could reopen the Strait of Hormuz. Nigeria’s inflation climbed for a third straight month to its highest level since November. And the NGX banking index plunged 10.49% in a brutal selloff.
Here are the highlights you missed.
Global Economy
US: Iran Deal Lifts Markets
Most major US equity indices closed the holiday-shortened week higher, supported by improved investor sentiment after the US and Iran signed a memorandum of understanding that could pave the way for the reopening of the Strait of Hormuz. Markets reacted positively nonetheless because the direction is right. A closed Strait of Hormuz passing 26% of global oil trade has been the defining supply shock of recent months. Any credible progress toward reopening that chokepoint justifiably moves oil prices and risk sentiment.
The Nasdaq Composite outperformed, advancing 2.43%. The Russell 2000 gained 1.21%. The S&P 500 rose 0.93%.
But the Federal Reserve’s policy meeting complicated the picture significantly. The central bank left the federal funds rate unchanged at 3.50% to 3.75%, in line with expectations. What wasn’t expected was the shift in forward guidance. Updated projections now show policymakers expect modest tightening by year end. The Fed also revised its inflation outlook upward for 2026, with headline and core PCE inflation forecasts moving higher.
Comments from Chair Kevin Warsh emphasized the Fed’s commitment to price stability in a tone markets interpreted as hawkish. The comments pushed short-term Treasury yields higher midweek before broader risk sentiment improved as the Iran MOU news dominated. The week ended on a positive note, but the underlying message from the Fed is clear: rate cuts are off the table, and a hike is now being considered.
Japan: First Rate Hike to 1% in Three Decades
The Bank of Japan raised its short-term policy rate by 25 basis points to 1% in a widely expected move, bringing borrowing costs to their highest level since 1995. Japan has maintained near-zero or negative interest rates for most of the past three decades in an attempt to escape deflation and stimulate economic activity. Raising rates to 1% is the most decisive step yet in unwinding a decades-long experiment with ultra-loose monetary policy.
The decision was aimed at managing inflation risks from Middle East tensions and addressing sustained yen weaknesses. For Japan, which imports virtually all of its energy and significant portions of its food, yen weakness directly translates into higher consumer prices. The BoJ is using rate hikes to make yen-denominated assets more attractive and slow the currency’s decline.
Governor Kazuo Ueda was absent due to a recent hospitalization. Deputy Governor Shinichi Uchida led the post-meeting press conference. He highlighted the risk that underlying inflation could exceed the BoJ’s 2% target, reinforcing expectations that further rate hikes may be forthcoming.
Japanese government bond markets reacted with relative calm. The 10-year yield eased slightly to 2.61% from 2.63%. The yen weakened to around JPY 160.8 against the dollar from JPY 160.2, increasing speculation about potential FX intervention. Japanese authorities reiterated readiness to respond to excessive currency volatility.
Sub-Saharan African Economies
African Eurobonds showed mixed but relatively contained movements. Nigerian papers were broadly stable.
Nigeria: Inflation Rises for Third Consecutive Month
Nigeria’s annual inflation rose for a third consecutive month to 15.93% in May 2026, up from 15.69% in April and the highest since November. The question now is whether June brings a fourth consecutive increase or whether the monthly momentum, which is already slowing, translates into a headline pause.
Food inflation accelerated for a fourth straight month to 16.96%. Transport inflation rose to 17.1%. These are the two categories that dominate household budgets for most Nigerians. The fuel price shock in March linked to Middle East tensions continues passing through to these categories months later. Core inflation climbed to 16.82% from 15.86% the previous month. Core strips out volatile food and energy prices to show underlying price trends.
The one relatively positive signal is the monthly pace. CPI rose 1.75% in May, slowing from 2.13% in April. Monthly deceleration while annual inflation is still rising means the rate of increase is easing even if the level hasn’t yet peaked. If this monthly slowdown continues into June, the annual rate should start moderating sometime in Q3. But that’s conditional on no new shocks arriving to re-accelerate the monthly pace.
South Africa: Energy Costs Push Inflation Higher
South Africa’s annual inflation rose for a third straight month to 4.5% in May 2026, the highest since July 2024, though slightly below expectations of 4.7%. Transport inflation jumped to 9.4% on higher fuel costs linked to Middle East tensions. Housing and utilities rose to 5.3% amid Eskom tariff increases.
Food inflation continued to ease, which provides some relief for households but doesn’t offset the transport and utilities increases for most spending patterns. Core inflation climbed to 3.8%, a one and a half year high, indicating persistence in underlying price pressures. South Africa’s central bank had been in an easing cycle. Three consecutive months of rising inflation with core at a 1.5-year high complicates that trajectory.
Domestic Economy
Major Updates During the Week
1. FAAC Distribution Rises as VAT Surges
Nigeria’s FAAC allocation rose 11% month-over-month to ₦2.3 trillion in May 2026, driven by a 45% surge in VAT collections that offset weaker oil revenues. VAT is collected on the value of goods and services consumed domestically.
The fact that VAT can offset weakening oil revenues is itself significant. For most of Nigeria’s fiscal history, oil revenues dominated FAAC distributions. When oil prices fall or production disappoints, allocations to states and local governments suffer. A VAT surge large enough to compensate for oil weakness represents a meaningful shift in the revenue composition that states can rely on. Non-oil revenues being this responsive to economic conditions creates a more diversified fiscal base.
However, bearish global crude prices are expected to weaken future disbursements. With oil prices under pressure from potential Middle East de-escalation and softening global demand, the oil revenue side of FAAC faces headwinds. Federal, state, and local governments that planned spending based on recent high FAAC levels may need to adjust expectations for the second half of 2026.
2. Inflation Hits 8-Month High
Nigeria’s headline inflation ticked up slightly for the third consecutive month to 15.93% in May 2026, fueled by a sharp rise in food inflation to 16.96%. A slowdown in month-on-month momentum is expected to maintain a cautious policy outlook from the Central Bank.
Equity Market: Banking Sector Leads Sharp Decline
The Nigerian stock market turned sharply bearish in the third week of June, with the NGX All-Share Index dropping 3.59% to close at 235,941.27 points. Market capitalization fell 3.59% to ₦151.32 trillion. The decline was broad-based and heavy. Seventy-eight equities declined against just eleven gainers.
The Banking index led the sell-off, plunging 10.49% for the week. FIRSTHOLDCO fell 20.29%. GTCO dropped 15.01%. The banking sector had been recovering from similar losses in earlier weeks. Successive sharp declines suggest something more systematic is pressuring the sector beyond just short-term volatility. Rising inflation, elevated interest rates, potential credit quality concerns, and regulatory uncertainty are all factors that can compound into sustained banking sector weakness.
The NGX temporarily suspended trading in Fortis Global Insurance on June 17 for a routine regulatory reconciliation of shareholder records ahead of a reconstructed shares listing. Temporary trading suspensions for regulatory purposes are administrative procedures that ensure the shareholder register is accurate before significant corporate events. However, suspensions during a broader market selloff can amplify uncertainty if investors conflate routine regulatory actions with distress signals.
Fixed Income Market: Inflation Data Drives Yields Sharply Higher
The Nigerian bills market showed mixed performance during the week. Average Treasury bill yields rose 28 basis points to 18.13% on weaker secondary demand. OMO bill yields dipped 9 basis points to 20.69% on sustained interest.
At the June 17th primary auction, the DMO allocated ₦1.49 trillion against a ₦1.00 trillion offer, drawing ₦1.86 trillion in total subscriptions. The oversubscription shows demand for government paper remains strong despite rising yields. 89.27% of subscriptions concentrated in the 364-day tenor. Stop rates increased across all maturities, peaking at 17.34% for the 364-day bill, driven by rising May inflation data.
The FGN bond market closed bearish with benchmark yields rising across the curve. Short-term bond yields jumped 67 basis points to 17.47%. Mid-term yields rose 58 basis points to 17.37%.
The Bottom Line
The US and Iran got a peace deal, which could lower oil prices and ease global inflation. The Fed’s hawkish pivot keeps the dollar strong, which pressures emerging market currencies. And Nigeria’s inflation keeps climbing, which erodes purchasing power no matter how high fixed-income yields go.
For the average investor, the week offered three clear signals. First, global geopolitics can shift quickly, and the investment landscape shifts with it. Second, inflation is sticky, and central banks are choosing to fight it rather than accommodate it. Third, sector rotation is real. The banks that led the market up are now leading it down.
The response is not to panic, but to recalibrate. Check your exposure to banking stocks. Ensure your fixed-income returns are beating inflation and review your portfolio to be sure it’s positioned for a world of higher rates, stronger dollars, and selective growth.
