This week, the Federal Reserve's updated rate projections turned materially more hawkish under new chair Kevin Warsh, as Iran war energy inflation also pushed the Bank of Japan to a 31-year rate high. China issued its first AI governance rules for banks and insurers and launched a new yuan liquidity tool for foreign central banks.

Read more on the week's key developments:

1. Hormuz status disputed three days after signing, ceasefire terms unresolved

Iran's top military command claimed on 20 June that the Strait of Hormuz was closed, just three days after the US-Iran ceasefire MOU, accusing Washington and Israel of violating the agreement through continued strikes in Lebanon. Iran's navy warned ships to stay clear, and called the closure a first step, with further measures threatened if the alleged violations continue. The US disputed the claim outright: US Central Command said commercial traffic through the Strait actually increased that day, with no Iranian action to close it detected on the ground.

The contradiction leaves the Strait's practical status unresolved heading into talks on a permanent settlement in Switzerland. For banks with Gulf, trade-finance or energy exposure, this widens the range of outcomes the 17 June MOU had appeared to narrow.

2. Fed signals hike as inflation outlook worsens

The Federal Open Market Committee (FOMC) held the federal funds rate at 3.50%–3.75% on 17 June, but its updated projections told a more hawkish story. The median year-end rate projection moved to 3.8% from 3.4% in March, above the current 3.50%–3.75% range, with nine of 18 participants projecting at least one hike before year-end. As many as 17 of 18 participants see inflation risks tilted to the upside, and the Fed lifted its 2026 inflation forecast to 3.6% from 2.7%. New chair Kevin Warsh also stripped the statement down to 130 words, a third of April's length, cutting all forward-guidance language and declining to submit his own rate projection. The UAE central bank held its rate at 3.65% the same day, tracking the Fed via the dirham peg.

The shift in projections, paired with the loss of forward guidance, changes the planning assumptions banks have relied on for liability repricing and net interest income forecasting.

3. US banks flag $22 billion capital hit in final Basel III submission

Large US banks made their final case to the Federal Reserve on 18 June, as the comment period closed on its revised Basel III capital rules proposal. A joint letter from the American Bankers Association, Bank Policy Institute, Financial Services Forum, Consumer Bankers Association and the US Chamber of Commerce argued the proposed changes to Basel III, the GSIB surcharge and annual stress tests would cut capital at the eight largest global banks by roughly $22 billion, or 2.7%. Their main asks are lower trading book capital charges, removing the requirement to hold capital against unused credit card lines and pushing the GSIB surcharge baseline back to 2015.

The letter is the industry's final input before the Fed finalises the rules, and the $22 billion figure represents the industry's estimate of capital that would be removed from the system under the proposed rules, and sets the floor for the argument banks will make if the final version differs from what they proposed. The same week, the UK PRA proposed easing its own trading book rules and the EU moved toward subsidiary level capital waivers.

4. Germany blocks UniCredit's Commerzbank bid on price grounds

Germany's Federal Finance Agency formally rejected UniCredit's share exchange offer for Commerzbank on 16 June, the final day of the initial acceptance period, saying the offer did not provide an adequate premium over Commerzbank's prevailing share price. The decision came from the interministerial steering committee of the Financial Market Stabilisation Fund, which manages Germany's stake of more than 12% in Commerzbank, acquired during the 2008 financial crisis. UniCredit's offer had valued Commerzbank at approximately €37.33 ($41.94) per share. Frankfurt prosecutors separately confirmed a preliminary investigation into possible market manipulation, following a criminal complaint from Commerzbank's workers' council. An extended acceptance period now runs from 20 June to 3 July.

The rejection shows a government shareholding can block a cross-border bank takeover when the political will exists to use it. UniCredit can still pursue a majority through the extended offer period, but it would do so without state support and under an active prosecutorial inquiry.

5. UK Prudential Regulation Authority eases internal model rules for trading risk

The Prudential Regulation Authority (PRA) published a consultation paper on 19 June easing how banks calculate capital for trading risk using their own internal models. The main change extends a key model accuracy test from one year to three, so a desk that fails it will not be automatically forced onto the regulator's more conservative standard approach. The PRA also loosened the data requirements for including a position in the model at all. The January 2028 start date is unchanged, and the PRA estimates the proposals would save UK banks between GBP 1.9 million ($2.5 million) and GBP 3.8 million ($5.0 million) per firm annually.

For UK banks building toward using their own models, this lowers the risk of a desk being bumped onto the costlier standard approach over test calibration issues rather than genuine model failures.

6. China's new AI rules require oversight for credit, trading and claims

China's National Financial Regulatory Administration (NFRA) published 32-point guidance on 18 June covering the safe development and use of AI in banking and insurance. High-risk applications, explicitly including fund trading, credit approval and underwriting and claims settlement, now require risk management committee approval and NFRA notification before deployment, with mandatory human oversight at key decision points. The guidance also bans the use of personal data to train generative AI models, and requires large institutions to build independently controllable computing infrastructure while extending computing services to smaller ones.

This is the first dedicated AI regulatory framework the NFRA has issued for banking and insurance institutions, according to China Daily. All institutions under NFRA supervision, including foreign bank subsidiaries and branches operating in China, will need to assess whether their existing AI governance arrangements meet the new requirements.

7. Bank of Japan hikes to 1.00%, a 31-year high

The Bank of Japan's Policy Board voted 7-1 on 16 June to raise the overnight call rate by 25 basis points to 1.00%, the highest level since September 1995. Board member Asada Toichiro dissented, citing greater downside risks to production and employment than upside risks to prices. The board met under Deputy Governor Ryozo Himino, with Governor Ueda absent due to hospitalisation.

The board said underlying inflation is approaching its 2% target and that it will keep raising rates while watching how the Middle East conflict affects Japan's economy and prices. A rate at 1.00% is expected to widen net interest margins on yen lending and returns on JGB holdings, consistent with the record profit guidance each of MUFG, SMFG and Mizuho issued at their full-year results announcements in May 2026.

8. PBOC launches yuan repo facility for foreign central banks

The People's Bank of China announced a new RMB repurchase facility on 17 June, letting overseas central banks, sovereign wealth funds and international financial organisations obtain yuan liquidity by posting RMB-denominated bonds as collateral. Governor Pan Gongsheng unveiled the facility at the 2026 Lujiazui Forum in Shanghai, alongside authorising six banks to conduct offshore foreign exchange transactions in the Shanghai Free Trade Zone. Pan also said maintaining China's previous pace of credit growth is "difficult and unnecessary."

The facility gives overseas central banks yuan access against bond collateral without needing an onshore account. Pan's statement that China's previous pace of credit growth is difficult and unnecessary to sustain signals a shift in the direction of Chinese monetary policy that banks with China-linked credit or trade finance exposure will want to monitor.

9. HSBC partners with Google Cloud, sets $100 million AI threshold

HSBC and Google Cloud announced a multi-year partnership on 17 June to deploy AI across HSBC's global operations, using Gemini models, the Gemini Enterprise Agent Platform and forward-deployed Google DeepMind engineering teams. The programme targets over 200 new AI use cases over two years, with HSBC prioritising those it estimates will deliver more than $100 million each in revenue gains or efficiency savings. Initial focus areas are wealth management support, financial crime risk management and an AI decision assistant for frontline staff.

The $100 million threshold gives peer banks a concrete benchmark for the scale HSBC is targeting per initiative, rather than for the programme overall.

10. Indonesia hikes for the fourth time since May as Philippines ends its easing cycle

Bank Indonesia raised the BI-Rate by 25 basis points to 5.75% on 18 June, its fourth increase since May, as the rupiah traded around IDR 17,826 per dollar, down roughly 7% year to date. The same day, the Bangko Sentral ng Pilipinas (BSP) raised its benchmark rate by 25 basis points to 4.75%, reversing an easing cycle that had cut rates by 225 basis points between August 2024 and February 2026. BSP inflation is running at 6.8% in May against a 2%–4% target, and Governor Eli Remolona said that even if the Strait of Hormuz reopens, several months of infrastructure rebuilding will be needed before oil prices return to pre-conflict levels.

Both Southeast Asian nations raised rates on the same day, both driven by Iran-war energy inflation. For banks active in either market, rising funding costs and compressed margins on lending priced during the prior easing cycle are the immediate consequence.

What to watch: Fed stress test results (24 June); UniCredit-Commerzbank extended acceptance period closes (3 July); US bank Q2 results (week of 13 July); Bank of Korea rate decision (16 July); ECB rate decision (23 July); Federal Reserve FOMC (28–29 July); Bank of Japan policy meeting (30–31 July)
