Middle East shipping disruptions push up oil prices, putting inflation and interest rates under pressure

On Monday (2026-09-14), U.S. large-cap stocks started off weaker. SPY fell 0.38%, down 1.15% over the past 5 trading days; QQQ fell 0.82%, down 1.38% over the past 5 trading days. ETF Radar's main theme to watch today is still the chain of "oil, inflation, and interest rates."

The first link in this chain comes from Middle East shipping. Yemen's Houthi forces continue to advance along the Red Sea coast, and have tightened oil shipping routes toward the Bab el-Mandeb; at the same time, there were reports of ships attacked in the Strait of Hormuz. The Bab el-Mandeb and the Strait of Hormuz are chokepoints for global energy transportation. Plainly speaking, crude oil is like trucks crossing a bridge—if the bridge mouth is constrained, the market first worries "will there be enough oil to deliver, and will deliveries get more expensive?"

So the second link is direct: concerns about oil and gas supply rise, and pressure on energy prices is harder to ease. News also mentioned that a key Saudi oil pipeline has been shut, and in Europe there are voices saying this round of inflationary shock could last longer than previously thought. Plainly speaking, oil prices aren't just about gas stations; they ripple through transportation, chemicals, power, heating, and finally into store shelves and service prices. Imagine deliveries, airfare, and heating all costing a bit more—inflation won't come down easily.

The third link reaches central banks. The fresh news in the U.S. is that inflation has made "whether the Fed needs to raise rates further" tense again, and even the clash between Trump and Kevin Warsh's positions has been amplified by the media. There's an interesting contrast in the U.K.: the British economy is described as "quite resilient," yet the market simultaneously feels that it would be a surprise if the Bank of England suddenly turned particularly hawkish. "Hawkish," in plain terms, means the central bank is more willing to keep rates high or even raise them. As long as oil prices and inflation are misbehaving, central banks won't dare loosen policy too quickly.

The fourth link is what markets care about most: asset prices. If inflation is a bit higher, central banks will be reluctant to rush into rate cuts; if rates are a bit higher, borrowing costs rise; with higher borrowing costs, smaller companies, real estate, and long-duration assets are often the first to struggle. "Duration," in plain terms, refers to assets that are especially sensitive to interest rate changes—like long-term bonds, whose prices are more easily pressured when rates rise. The same applies to stocks, especially sectors whose valuations rely on "profits many years into the future"—when the discount rate goes up, the price buyers are willing to pay today gets discounted.

However, there's a real contrast on Monday's tape: energy hasn't risen exaggeratedly, while semiconductors have fallen more noticeably. SOXX fell 5.52%, SMH fell 4.63%. This shows the market is simultaneously digesting other pressures in the short term, such as profit-taking after prior gains or worries about economic slowdown. Plainly speaking, the news mainline is "oil and interest rates," but trading desks are also executing "let's trim the high-volatility sectors first," so the picture won't be neat and uniform.

One more side thread separate from today's mainline. In China, news on financial regulation and financing support continues to ferment. There have already been fiscal and central bank actions, and in the past two days the China Securities Regulatory Commission revised regulatory measures for futures firms, and the state-owned assets system emphasized easing difficulties in SMEs collecting payments. Plainly speaking, this is more like fixing the pipes and adding liquidity to keep the financial system and corporate cash flows from getting clogged. It's not the same line as Middle East oil shipping, but it will affect emerging market sentiment, especially how capital views China and Asian assets.

Next, we look at several related ETFs, separating "what has already occurred in the price action" from "what the models see next."

First, look at XOP, which is the U.S. oil & gas exploration and production sector. XOP's actual change over the past 5 trading days is not listed separately in this input for weekly decline, so here I can only reference the shorter-term market action. Among similar energy ETFs, on Monday USO rose 1.73%, BNO rose 1.97%, indicating the oil-price complex is still gaining momentum. Looking forward, the ETF Radar model is biased positive on XOP, with fairly consistent signals. In quantitative readings, the CFTC COT net long is +111,731 contracts, and week-on-week it added another +17,450. COT net long, in plain terms, is the large traders' bullish positions after subtracting bearish bets—the remaining net bullish exposure. The second reading: WTI front month 103.59, versus 12 months out 73.9, slope of the curve 40.176%. This indicates front-month oil is much more expensive than the back months—in plain terms, the market thinks near-term oil is tighter. The third reading: OVX is 60.76. OVX can be understood as the oil market's "stress thermometer"—the higher it is, the more concerned participants are about volatility and supply risk. But also note a reality: XOP had net outflows of -2.57% AUM over the past 5 days. AUM is the fund's total assets under management; this number means some money is being withdrawn, so the bias is positive but not without bumps along the way.

Second, look at IEF, which is the 7- to 10-year U.S. Treasury sector. IEF actually fell 1.17% over the past 5 trading days. And looking forward 1 to 3 months, the ETF Radar model is biased negative on IEF, with fairly consistent signals. There are three core readings here. First, the CFTC COT net position in 10-year Treasury futures is -1,938,754 contracts. Such a large net short, in plain terms, means large traders are generally positioned for bond prices to fall, i.e., yields to rise. Second, the 10-year Treasury yield is 4.95%, with a term premium of 0.8892%. Term premium, in plain terms, is the extra return investors demand for lending to the U.S. for a longer period. Third, U.S. core CPI month-over-month 0.3%, above the expected 0.2%. Core CPI excludes volatile items like food and energy to show the underlying inflation temperature. The transmission is straightforward: hotter inflation makes it harder for the market to price in rapid rate cuts, putting more pressure on long bonds. Note that on Monday IEF actually rose 0.18% for the day, which is a short-term divergence: down over the past 5 trading days but a small rebound on Monday; the model is looking at the next 1 to 3 months, not one-day sentiment swings.

Third, look at IWM, which is U.S. small-cap equities. IWM actually fell 2.48% over the past 5 trading days. Going forward, ETF Radar is biased negative on IWM, with fairly consistent signals. The first quantitative piece of evidence: the Russell 2000's CFTC net position is -110,147 contracts, and it sits in a very bearish part of its own range. Second, since 2026-09-04 net outflows are -$215M, i.e., an outflow of 2.15 hundred million USD; 30-day cumulative outflow -0.78% AUM. The meaning is straightforward: money is leaving. Third, IWM's excess return versus SPY is -3.80%. Excess return, in plain terms, means small caps have fallen 3.8% more than the broad market. This aligns with the earlier interest-rate chain: when rates are high, small companies that rely more on external financing generally suffer more. Here price and the model agree: it has been falling over the past week and also down 5.38% over the past 1 month, so the market is validating that logic.

The fourth is EEM, which is emerging markets. EEM actually fell 3.76% over the past 5 trading days. Looking further back, the ETF Radar model is biased positive on EEM, with fairly consistent signals. It should be noted that this does not have a direct causal line to today’s “Middle East shipping → energy → inflation → rates” theme; it is more like an independent mid-term stance. The readings supporting it mainly come from the China financial support thread. First, EEM 30-day subscription/redemption flows +1.52% AUM, 90-day +3.17% AUM. Subscription/redemption flows, in plain terms, indicate whether money is continuously flowing into this fund. Second, U.S. Fed net liquidity 4-week +$60B. Net liquidity can be simply understood as extra liquidity in the market; when there is more liquidity, risk assets are generally easier to be noticed. Third, EEM’s current price window has cumulative only -0.17%, which shows that although it fell in the past 5 trading days, there has not been a particularly large mid-term breakdown. Here is a clear divergence: it has been falling in the past week, yet the model leans positive. The reason is that the model captures policy and capital chains, while short-term market moves are being pressured by global rates and risk appetite.

Also add SMH, which fell conspicuously today but the model still leans positive. SMH’s specific moves over the past 5 trading days are not listed separately in the inputs, but on Monday it fell 4.63% in one day, and it has fallen 7.76% over the past 1 month. The ETF Radar model is biased positive for the next 1 to 3 months, with fairly consistent signals. On the readings, SMH has net inflows since 2026-09-03 of +$1,554M, that is an inflow of 15.54 hundred-million USD, approximately +2.19% AUM; 30-day and 90-day also saw inflows of +0.94% and +6.16% AUM, respectively. Second, DRAM spot front-month rose 13.81%, DDR5 16Gb rose 18.72%. In plain terms, memory chip prices are rising, indicating an improvement in supply and demand. Third, SMH’s ATM IV percentile is only 13%. IV is implied volatility, which can be understood as the score the options market gives to future volatility; a low percentile means the market is not treating it as 'super risky'. Again, honestly point out the divergence: semiconductors were heavily sold on Monday, but the model is looking at 1 to 3 months of capital and supply/demand, not a one-day emotional vent.

Putting the news and quant together today, the picture is actually very clear: Middle East shipping risk pushed up energy concerns, energy concerns increased inflation stickiness, and inflation stickiness lengthened the pressure to keep rates elevated, so long bonds and small caps are more likely to be pressed; at the same time, China’s financial support has left a mid-term repair path for emerging market assets like EEM.
